The steel making process involves three main stages:
1) Preparing iron ore by removing impurities through washing, crushing, and sieving.
2) Using a blast furnace to heat iron ore, coke, and limestone above 1500°C to produce pig iron.
3) Further processing pig iron in a converter to reduce its carbon content and remove impurities by adding oxygen and scrap, producing the final liquid steel.
Steel is made through a process that begins with iron ore, coke, and limestone being fed into the top of a blast furnace. Hot air blown into the bottom of the blast furnace causes a series of reactions where carbon monoxide reduces the iron ore to molten iron, which is drained from the bottom. The limestone also reacts to form slag, which is separated from the molten iron. The molten iron can then be cast or further processed to produce steel, which has a variety of important uses including in construction, automobiles, packaging, and infrastructure. Steel production is crucial to modern society but manufacturers must consider the environmental impact of their processes.

How steel is helping to achieve a global circular economy (Author: Clare Broa...POSCO Research Institute
There is an increasing focus on making products last longer, reusing or mending them, or even remanufacturing them. This new concept has been branded a circular economy where the focus is on reduce, reuse, remanufacture and recycle (4Rs). The steel industry is well placed to contribute to a circular economy and is part of the solution in addressing environmental concerns for many products and services. Key properties of steel (strength, durability, magnetic properties) make steel a key enabler of a circular economy. This article outlines how the steel industry is addressing current environmental issues as well as how regulations can be utilized to generate an overall environmental improvement of products and services.
Improving sustainable competitiveness in preparation for a circular economy ...POSCO Research Institute
In terms of sustainability and a circular economy, steel is not free from environmental concerns, but steel can become a cornerstone for a sustainable circular economy considering lightweighting, long service life, and rich iron ore reserves, Based on whole life cycle, POSCO is applying life cycle assessment (LCA) to develop products from the perspective of sustainable competitiveness and improve their eco-friendliness. Representative products to which LCA was applied include advanced high strength steel (AHSS), Hyper NO electrical sheet, Giga Steel, and PosMAC.
AHSS applied to gasoline vehicles reduces vehicle body weight, improving fuel efficiency and reducing greenhouse gas emissions. Motor cores with Hyper NO minimize core losses, thereby improving the power efficiency of home appliances and cut greenhouse gas emissions. In terms of PosMAC and Giga Steel, POSCO is preparing for a low-carbon circular economy through a full life cycle database and third-party certification. Developing “PosMent” with a higher slag content, POSCO is strengthening the circular industry ecosystem and reduce greenhouse gas emissions.
The decoupling of gdp and steel demand cyclical or structural (Author: Cheol...POSCO Research Institute
In the 2000s, global steel demand growth consistently surpassed global GDP growth. The dip in global steel demand after 2012 can be mostly explained by the slowdown in global investment and exports. China shifted its growth strategy from investment and exports to consumption as President Xi Jinping took power in November 2012.
∙ The decoupling of GDP and steel demand will last for the time being on several aspects: global investment and exports, raw materials prices forecast, mega trend (aging populations, the sharing economy and the Fourth Industrial Revolution), and major forecast institutions’ prospects. Just as the decoupling of global GDP and steel demand persisted until China emerged as a new growth engine for steel demand after the early 2000s, there is a possibility that the decoupling will repeat. The global steel industry should prepare for this.
A Comprehensive Survey of Steel Demand Forecasting Methodologies and their Pr...POSCO Research Institute
This article classifies and compiles the methodologies through a comprehensive review of the literature, and then finds clues to enhance the accuracy of steel demand forecasting.
The approaches for forecasting steel demand can broadly be classified into the econometric and intensity of use (IU) approaches.
Econometric approaches are divided into the econometric demand model and vector autoregression (VAR). The econometric approach widely uses a simple single equation or a simultaneous equation to forecast steel consumption, considering that steel demand is affected by macroeconomic variables including GDP, industrial production, trade structure, and economic volatility. The VAR methodology has the merit of avoiding the weakness of econometric demand model that requires forecasts of exogenous variables since VAR assumes all variables in a model are endogenous.
The intensity of use (IU) approaches rose to prominence in the early 1970s when some OECD member countries observed their steel demand fall while macroeconomic indicators grew. The IU approach is a useful concept that attempts to link steel consumption to the technological and structural changes in an economy.
Mathematical methodologies and computational approaches
Hybrid mathematical methodologies seek to enhance predictability based on the grey model, algorithm, and fuzzy ARIMA model. The steel weighted industrial production (SWIP) index is broadly used by worldsteel and other steel associations.
To complement the weakness of top-down macro methodologies which directly predict total steel demand, POSRI is concurrently applying a bottom-up micro methodology to predict demand for 16 steel products and summing them to forecast total demand.

The Korean Steel Industry in Retrospect : Lessons for Developing Countries
Rising from the ashes of war, Korea has joined the ranks of advanced countries. The rapid development of the Korean steel industry offers lessons to developing countries. The development patterns differ before and after the financial crisis of 1998. Examining the changes that took place around the crisis of 1998 based on factors related to steel use, there are some distinctive items: a significant slowing in the urbanization rate after 1996, gross capital formation as percentage of GDP declining after peaking in 1996, and the Korean economy being shifted from government-driven to market-driven. The author adopted various theories to re-examine the success factors and offer implications for developing nations—catch-up theory, infant industry argument, fourth factor of production, Lewis turning point, and endogenous growth theory.
Based on its analysis on the development and success factors of the Korean steel industry, this article offers several policy implications for developing countries. The first is the importance of the government’s role and strategic decisions. The second implication is entrepreneurial leadership and a “can-do” attitude. The third is the importance of industrial policy based on medium- to long-term outlook for supply and demand. Finally, there is the importance of determined drive of technological development and R&D investment.

Restructuring Scenario of the Indian Steel lndustry to Enhance Its Global Competitiveness
The Indian government has recently released the“National Steel Policy (NSP) 2017,”which declares the aim of increasing steel production capacity from 122 Mt in 2015 to 300 Mt in 2030 in order to attain self-sufficiency. However, the insolvency issue recently looming large in the Indian steel industry makes this goal appear somewhat hollow. As of March 2016, the Indian steel industry’s debt surpassed INR 3 trillion, and between INR 1.15 to 2 trillion within it is categorized as non-performing assets. However, steel imports are not the only culprit in the insolvency of the Indian steel industry. There are other fundamental reasons underlying the insolvency. The first relates to policies based on the ripple effect from the NSP 2005. The second cause of insolvency is investment fervor among Indian steelmakers, which left huge aftermath within the industry. Restructuring of the Indian steel industry will be mainly led by Tata and JSW.
Now is the right time for the Indian government to seek not only quantitative growth, but also qualitative improvement to enhance the global competitiveness of the domestic steel industry.

Chinese Steel Moves along the One Belt, One Road
After President Xi unveiled the concept of a“New Silk Road”in September, the Chinese government began to actualize the“New Silk Road”and announced One Belt, One Road (OBOR) in March 2015. China has contributed USD 40 billion to a Silk Road Fund to finance OBOR and established the Asian Infrastructure Investment Bank (AIIB). China also held a major OBOR summit in May 2017. The Chinese steel industry has begun to search for a way forward through OBOR for the following reasons: falling steel consumption; prolonged oversupply with declining steel prices; and the spike in financial, environmental, and labor costs. The OBOR project is positive in that it boosts steel demand and address overcapacity; however, it needs adjustment and balance to prevent any dispute and side effect.

The Impact of Sino-Indian Economic Cooperation on the Indian Steel Industry
In the mid-2000s, Sino-Indian trade and investment began to expand. In light of India’s strategic culture, the economic cooperation between India and China will continue. India exports iron ore to China, while it imports steel products from China. India’s trade deficit with China is surging, dragging India down into chronic steel deficits with China. In early this year, the Indian government released draft National Steel Policy of 2017 (NSP) with an aim to boost its crude steel capacity to 64 Mt by 2030 to satisfy the continuously rising domestic steel demand and to export some steel products.

Global steel demand will rise by around 1% for the next 20 years, reaching 1.69 billion tonnes by 2025 and 1.86 billion tonnes by 2035. Despite some concerns, global steel demand has not yet peaked and will not do so within the next two decades. Steel-consuming industries’ requirements for steel products will become stricter and more diverse under the influence of evolving megatrends. Their needs will become more sophisticated mainly in three areas: high strength and high toughness, high corrosion resistance, and high performance. The rising megatrend of global climate action will compel steelmaking processes to become more eco-friendly. For the long term, the steel industry is gearing up to develop carbon-free technologies such as the hydrogen reduction process. Under the other emerging megatrend of the Fourth Industrial Revolution, the steel industry will seek a smart transformation using IoT, Big Data and AI.

Will the Shipbuilding Industry Flourish Again?
The shipbuilding industry will be recovered in the long term backed by global economic growth and highly influenced by environmental issues and technological advances. Under strict environmental regulations, demand for eco-friendly ships will rise. Ships will be required to use low-sulfur fuel oil. A wide range of technologies will bring about differentiated and innovative types of ships. Under the influence of the Fourth Industrial Revolution, remotely controlled or fully autonomous ships will become available in the future. Emerging technology will not only change ships, but also shipyards and the shipping and port industries. The changing steel industry will result in qualitative changes of steel products. As vessels become larger and lighter, the steel intensity of ship’s tonnage will fall continuously, and then decline even further following the rise of electric propulsion, unmanned, and autonomous ships.
The Impact of China’s Early "Peak Steel" and Scrap Generation on Steel Raw Ma...POSCO Research Institute
1) China has already reached its peak steel demand of 766 million tons in 2013 according to POSCO Research Institute forecasts. Demand is expected to gradually decline to 670 million tons by 2020 and 650 million tons by 2025.
2) China's steel production growth slowing since 2013 has contributed to declining global iron ore and coking coal prices as major suppliers expanded capacity. China's steel production is strongly correlated with prices of these raw materials.
3) As China's steel demand declines and obsolete steel scrap generation increases, the structure of China's steel production is expected to change with increased electric arc furnace production and higher scrap usage in integrated mills. This will further reduce China's demand for iron ore and coking

The Demographic Cliff: How It Will Impact Asia’s Steel Demand
Changes in working-age population determine economic fundamentals. They are directly related to steel demand, because the working-age population is the main consumer group of houses and vehicles, the key sources of steel demand. Therefore, the acceleration of decline in working-age population will have a negative impact on economic growth and steel consumption.
Learning lessons from advanced countries about the experience of population aging, there are some characteristics in common: the share of manufacturing shrinks in the economic structure, while the share of service increases; and steel consumption declines after a peak. Particularly in the case of Japan, which is the world’s most aged society, changes in working-age population has a strong correlation with changes in the steel-consuming industries and steel consumption.
The decrease in working-age population in Korea, China, and Japan, which have led growth of the global steel industry until now, will have a negative impact on global steel demand in the medium to long term. It is unlikely that India and the ASEAN’s demand will grow fast enough to offset the decline in steel demand in the three East Asian countries.

Increased trade barriers in southeast asia following a rapid rise in steel im...POSCO Research Institute
The document discusses the steel industry in Southeast Asia. It notes that at a 2015 conference, Southeast Asian countries raised concerns about surging steel imports from China, which have doubled in recent years. This has led to a loss of competitiveness for domestic steel industries. Though steel production is rising in Southeast Asia, it still falls short of demand, which is met through imports, especially from China, Korea, and Japan. There is increased competition among steelmakers from these countries to establish production facilities and expand their businesses in Southeast Asia.

The myth and reality of global steel overcapacity (Jun H. Goh, Moon-Kee Kong)POSCO Research Institute
[Asian Steel Watch] Vol.1(2016.1)
Overcapacity has long been blamed as the main cause of the recession in the steel industry (especially the price decline), but this claim has not yet been backed by enough systematic analysis.
For this reason, the exact amount of overcapacity continues to be a controversial topic, and a consensus on realistic measurement of capacity is nonexistent. Therefore, one is hard-pressed to provide an insightful answer to the question of whether the current overcapacity level is more serious than the past.
In this article, we will first examine how serious global steel overcapacity is in terms of nominal amount. Reliable annual historical data for China and other countries are derived mainly from OECD data on nominal crude steel capacity, and are compared to annual crude steel consumption data. Next, we will try to measure the genuine steel overcapacity by introducing the concept of effective capacity, and investigate whether the steel industry’s recession after the financial crisis was triggered by overcapacity....

Accelerating Digital Transformation
with Smart Factory to Unlock New Value:
Case of POSCO
The Fourth Industrial Revolution is bringing
massive changes to mankind through accelerated
integration of traditional industries and ICT. The
Internet of Things (IoT), Big Data, and Artificial
Intelligence (AI) are forcing traditional industrial
structures to rapidly change. The scale, scope, and
complexity of these changes will be unlike any-
thing mankind has experienced. It is no coinci-
dence that new startups such as Google and Tesla
have outpaced traditional market leaders such
as IBM and GM. This is a sign that the time has
come for companies to move beyond the limita-
tions of traditional practices and seek innovative
transformation.
Manufacturing plays a fundamental role in
the economy, accounting for 16% of the world’s
GDP and 62 million diverse jobs. Since the start
of the Industrial Revolution 200 years ago, man-
ufacturing has changed the world through relent-
less advancement in the automotive, chemical,
machinery, electronics, and materials industries.
There is no doubt that manufacturing will con-
tinue to lead technological innovation in the
future. Products that will totally change our way
of life are continuing to emerge: electric vehicles,
self-driving cars, drones, and humanoid robots.
At the heart of the Fourth Industrial Revolu-
tion, manufacturing is poised to shift from “tra-
ditional” to “smart” through integration with ICT.
Leading global companies are already seeing new
growth opportunities through breakthrough in-
novations. General Electric is moving away from
its core financial business towards smart manu-
facturing under the name “Industrial Internet.”
Siemens’s Amberg factory has significantly re-
duced defect rates through IoT technologies, and
boasts the world’s best production quality rate at
99.9988%.
POSCO, one step closer to smart factory
In the face of the great paradigm shift brought on
by the Fourth Industrial Revolution, many Asian
steelmakers are taking preemptive measures to
maintain competitiveness and contribute to the
advancement of manufacturing. POSCO is also

one of the leading global steelmakers in this are-
na.
POSCO has been working diligently to adapt
to this paradigm shift with the Smarter POSCO
mandate, not only to continuously reinforce the
competitive edge of its core business, but also to
contribute to the advancement of manufacturing
industries. The Smarter POSCO mandate calls
for creating new, differentiated value through
digitalization and intelligence to unlock potential
value. Digitalization involves storing, analyzing,
utilizing, and emulating the data generated by
people, products, assets, and operations. Intelli-
gence harnesses the power of advanced machine
learning technologies to enable machines to un-
derstand, execute, and improve best practices.
Encompassing the goals of the Smarter POS-
CO mandate, POSCO defines smart factory as
an intelligent factory that senses, analyzes, and
controls itself by closely investigating and analyz-
ing production processes using ICT to optimize
production, thereby reducing costs, eliminating
defects, and minimizing downtime.
In concrete terms, a smart steelworks is a
facility that gradually evolves through “smart
sensing,” “smart analytics,” and “smart control.”
Smart sensing means collecting, translating
and connecting data from production sites in
real-time, increasing data’s visibility. Smart
analytics predicts the status of production pro-
cesses, that is, the flow of products on the fac-
tory floor and the conditions of manufacturing
assets, based on the integration of technological
(metallurgical) theory, expertise, and big data
analysis. Smart control means that intelligent
machines learn best practices and optimize pro-
duction.

try-specific requirements have to be factored in.
First, it is difficult to determine the root cause
of defects in plates by tracing processes because
the physical properties of steel change when mol-
ten steel solidifies into plates during the continu-
ous casting process, and plates are frequently cut,
flipped, and rotated. Second, adjusting or chang-
ing upstream and downstream production pro-
cesses that are online is costly and difficult. For
example, all materials are scheduled to go through
production routings and steps in a predetermined
order. If trouble occurs in the middle of a process,
former processes might be suspended until the
problem is solved. Third, various materials are
processed in the same facility, and a number of
facilities and production methods are involved in
making one kind of product, making it difficult to
find the exact cause of a problem.
Recognizing these complexities in producing
“World Premium (WP)” products, the Gwangyang
plate factory is building a model for the smart
factory by applying IoT, big data, and AI to pro-
duction, worker safety, and cost management.
POSCO tailored Germany’s Industry 4.0 ap-
proach to meet industry-specific requirements
with the following refinements: 1) Converted
academic and conceptual theories into practi-
cal, applicable actions at the shop floor level;
2) adopted a value-centered, outcome-driven
approach aligned with relevant policies; 3) inte-
grated domain knowledge with information and
communications technology, rather than simple
information technology-driven implementation;
4) employed an evolutionary approach rather
than a big-bang approach, and 5) flexibly adapted
strict Industry 4.0 standards that made sense for
deployment at the shop floor.
Here are the details and major outcomes by
phase of the smart factory at Gwangyang Steel-
works.
1. Selection of smart factory projects
In order to increase global competitiveness and
maximize customer value, POSCO developed a
mid- to long-term vision for the Smarter POSCO
mandate. Initiatives were then derived in the
The Fourth Industrial Revolution has already started and is expected to have a great
impact on the survival and development of companies. Steelmakers will strive for long-
term innovation to realize smart factories by interconnecting data across production
operations, quality and maintenance, upstream and downstream production processes,
followed by lengthwise alignment of material-to-final product data.

areas of production operation, quality, mainte-
nance, safety and energy. New ideas were born
through cooperation between experts in steel,
R&D, and IT, and were given shape in integrated
projects involving IoT technologies focusing on
sensing, analytics, and control.
Feasibility and potential outcome were
among the high priorities in the selection of
projects, with goals including quantification and
automation of work that used to depend on ex-
perience, combined analysis of interconnected
processes, utilization of forecasting and predic-
tion models, and expansion of autonomous con-
trol.
2. Development of the “digital genome map” to tackle
challenges of smart factory initiatives
POSCO undertook an extensive, thorough as-
sessment of data residing not only in production
control systems, e.g. PLC/DCS, but also in busi-
ness systems such as ERP and MES, as well as the
data generated by individual sensors installed
on production machines. This rigorous exercise
was geared towards the following: 1) identifying
data likely to impact production operation and
quality that had not been captured, stored, or
used (structured/unstructured and macro/micro
data); 2) standardizing descriptions and attri-
butes of about 60,000 data entities to ensure that
all stakeholders involved have a common under-
standing; and 3) charting out the digital genome
map of steelworks by interconnecting data across
production operations, quality and maintenance,
upstream and downstream production processes,
followed by lengthwise alignment of materi-
al-to-final product data.
To achieve this goal, POSCO has made full use
of microdata on manufacturing, where previously
we used only 6% while discarding the remaining
94%. Additionally, we have collected new, addi-
tional data using IoT technology.
In cases of customer claims, it is now possible
to quickly and easily trace the exact point where
a defect occurred, all the way back to raw mate-
rials. An issue can be addressed before it carries
into the next process and the cause of a previous
process’ issue can be resolved in the middle of
production.
3. PosFrame—POSCO’s smart factory platform for con-
tinuous process industries
Generally, a software platform is common soft-
ware where various applications can be developed
and serviced. A smart factory platform works as a
software substructure that supports smart sens-
ing, smart analytics, and smart control to realize
a smart factory.

for process industry applications. It empowers
POSCO to: 1) apply the digital genome map
to production operations through high-speed
collection and inter-connection of structured/
unstructured and macro/micro data; 2) rapidly
convert smart factory initiatives in domains such
as production operation, quality, maintenance,
safety and energy into applications with the same
ease and speed as building and deploying apps for
smart phones; 3) leverage a common platform to
adopt emerging technologies, including IoT, big
data, and deep learning, which are required for
smart factory implementations at the enterprise
level; and 4) cost-effectively roll out the smart
factory model to other similar factories with
standardized, re-usable software components.
In the future, POSCO will continue to adopt new
ICT for this platform and blend it with global best
practices.
4. Smart factory project execution and results sharing
POSCO ran pilot projects to validate business cas-
es and to secure success stories before initiating
full-blown smart factory projects. The experience
of each preliminary project was applied to the
next project, leading to a continuous evolution
and development of technologies and experienc-
es. Success cases were replicated at similar plants
in order to reproduce outcomes.
The smart factory plant, scheduled to be com-
pleted in 2017, seeks to change maintenance,
operations, quality, safety and energy as follows:
1) Maintenance: Pre-scheduled and regular
maintenance and repairs of defects will be re-
placed by predictive maintenance that finds de-
fects in advance.
2) Operation: Pre-scheduled production will be
replaced by real-time, adaptive production, resil-
ient to changes in demand, quality, and mainte-
nance status.
3) Quality: Reactive quality control will be re-
placed by real-time, on-the-spot quality control.
4) Safety: Worker safety has historically depend-
ed on physical barriers and safety training, but
IoT technology will automatically identify danger
Generally, a software platform is common software where various applications
can be developed and serviced. A smart factory platform works as a software
substructure that supports smart sensing, smart analytics, and smart control to
realize a smart factory.

and sound alarms.
5) Energy: Pre-arranged energy production and
distribution will be replaced by optimal energy
production and distribution based on changes
in supply and demand as well as changes in the
operating environment, thus saving costs and re-
ducing CO2 emissions.
In addition, virtual factories, which are cur-
rently used for training, will make product devel-
opment possible in cyberspace, reducing time and
expenses.
Key smart factory projects of POSCO
The following are some smart factory projects for
the Gwangyang steel factory: analyzing causes of
defects using a digital genome map, addressing
issues using big data, and utilization of AI and
virtual factories.
1. Material to final product defect tracking
During the course of processing plates, the steel
frequently changes length and shape. There-
fore, quality control engineers need much time
and effort to collect and analyze hundreds of
thousands of data sets generated during each
process in order to identify the causes of defects.
It is also difficult to find the precise cause. To
solve this problem, POSCO has devised a way
to collect real-time macro and micro data on
operations, quality control, and maintenance
corresponding to each unit of length and width
of products, and connecting the data from each
process phase, thus more than halving the time
needed for engineers to analyze data. For exam-
ple, if the surface defect detector (SDD) detects
any cracks in a plate, operation, quality control,
and maintenance data from the previous pro-
cesses are analyzed in 100mm increments of the
product in each phase, tracing back from plates
to mother plate and slab, as shown in Figure 2.
Doing this allows engineers to determine the
precise cause of a defect, leaving more time for
product improvement.
2. Minimizing unnecessary scarfing in the continuous
casting process
The scarfing process, which removes surface de-
fects from slabs, is the highest bottleneck process.
WP products are all scarfed, as they demand high
quality. However, in the case of general steel prod-
ucts, only slab samples are examined, and if there
is a defect, the whole lot of slabs with the defect is
scarfed. This means that normal slabs are unneces-
sarily scarfed. The recent increase in production of
WP products has overloaded the scarfing process,
necessitating the expansion of production capacity.
The Gwangyang smart factory analyzes struc-

tured and unstructured data from connected pro-
cesses and automatically detects surface defects
on individual slabs. This allows the scarfing pro-
cess to be conducted only when necessary, thus
reducing the load and using the current scarfing
capacity to produce more WP products. Finding
the root cause of quality defects improves the up-
stream processes (steel-making and continuous
casting), and guides the downstream processes
(rolling and shearing) to optimal operation, pro-
foundly reducing defects in the final product. This
is a prime example of problem solving using data
and software without expanding capacity.
3. New product development simulation in cyberspace
The steel-making process entails large-scale facility
investments, so it is difficult to have separate pro-
cesses to test new products. Moreover, owing to
the innate characteristics of steel production, it is
also difficult to create a new product and test func-
tions through design and simulation software, as
is done with home appliances such as refrigerators
and washing machines. To address these chal-
lenges, on-going research into virtual factories is
required to enable new product development and
simulation in a cyber environment. In a virtual
factory, facilities built by 3D technology are inte-
grated with advanced control algorithms and op-
erational technologies, based on steel production
knowhow, and used for training and advanced
commissioning. In the near future, virtual facto-
ries will be able to conduct pilot production, which
would otherwise require tremendous expense.
The Fourth Industrial Revolution has already
started and is expected to have a great impact on
the survival and development of companies. Tak-
ing this as an opportunity for growth, companies
should strive to advance manufacturing and create
new value for humanity.

term innovation in order to become a role model
for the advancement of global manufacturing.
Many Asian steelmakers are also actively devel-
oping advanced technologies to respond to the
massive paradigm shift caused by the Fourth
Industrial Revolution. In cooperation with indus-
try, academia and research, the leading steel mills
will continue to develop technologies such as AI
and virtual factories and apply them to produc-
tion sites. They will strengthen integration along
value chains by connecting clients and suppliers
through smart factories.
