Steel is the world’s most important engineering and construction material. Currently (year 2020) 1810 MT steel is produced world-wide for various uses. It is 100% recyclable and can be used infinitely. Steel Industries used advanced technologies and techniques to increase production yield rates and to facilitate the use of co-products. As a result of the intrinsic recyclability of steel, the value of the raw materials invested in steel production lasts far beyond the end of a steel products life. It is used in every aspect of our lives; in automotive to construction, home appliances to medical devices & many more.

Steel is the world’s most important engineering and construction material.
Currently (year 2020) 1810 MT steel is produced world-wide for various
uses. It is 100% recyclable and can be used infinitely. Steel Industries used
advanced technologies and techniques to increase production yield rates
and to facilitate the use of co-products. As a result of the intrinsic
recyclability of steel, the value of the raw materials invested in steel
production lasts far beyond the end of a steel products life. It is used in
every aspect of our lives; in automotive to construction, home appliances to
medical devices & many more.
STEEL IS PRODUCED BY TWO MAIN PROCESS
 The Blast Furnace- Basic Oxygen Furnace (BF-BOF) method

2.  Electric Arc Furnace (EAF) method
The key difference between the methods is the type of raw
materials they consume. For the BF-BOF methods are
predominantly iron ore, coal, and recycled steel, while the EAF
method produces steel using mainly recycled steel and electricity.
Depending on the plant configuration and availability of recycled
steel, other sources of metallic iron such as direct-reduced iron
(DRI) or hot metal can also be used in the EAF method.
Aluminum, cast iron, and steel are the most commonly processed
metals. The majority of coke comes from by-product coke ovens.
The coke is prepared in brick furnaces and volatile gas by-
products (primarily ammonia, coal tar, and gaseous compounds)
are collected and saved. In recovery coke plants the waste gas
exits into a waste heat recovery boiler which converts the excess
heat into steam for power generation. In non-recovery coke
plants, gas by-products collect in a common tunnel and exit via a
stack. Many foundries use generated heat to run boilers for site
power requirements, which involves measuring combustion air
flow and fuel flow to boilers, and measuring stack exhaust gas.
