Steel Melting Shop (SMS)
Rourkela Steel Plant was the first in Asia to adopt the LD steelmaking process and the first in India to use external desulphurization. It is also the only plant where 100% of slabs are continuously cast. The steelmaking process in SMS involves charging hot metal, scrap, and fluxes into converters where oxygen is blown to remove impurities through oxidation, producing slag. Molten steel is tapped and further processed before continuous casting into slabs. Waste gases are captured and recycled while dust and slag are also recycled in the process.
HR Coils
1. Hot rolling is a process where large metal pieces are heated and rolled into thinner cross sections between rollers.
2. The hot rolling process involves reheating slabs, descaling, roughing and finishing rolls to produce hot rolled coils.
3. Hot rolled coils have a wide variety of applications including tubes, pipes, automotive parts, general structures, and are used to make cold rolled coils and sheets.
Forging and casting technology
Forging is a process that shapes metal by applying pressure through hammers below the melting point. There are two main forging methods: closed die forging and cold die forging. Closed die forging provides high dimensional accuracy and the ability to create complex shapes in metals like steel, aluminum, and copper alloys. Cold die forging is done at room temperature up to a few hundred degrees Celsius and is used for lower alloy steels, stainless steel, aluminum, brass and bronze.
Casting involves using a pattern to create a cavity in a mold, which is then filled with liquid metal to produce the final product. Common metals cast include carbon and alloy steels, aluminum, and copper alloys.

increasing number of applications including magnet wire, electrical conductors, refrigeration tube and ultimately, in 1984, the introduction of the Conklad™ process for aluminium clad steel wire and CATV and fibre optic cables.
Report
The document provides an overview of the history and development of Tata Steel in India from its founding in 1907 up until modern times. It then describes a visit to Tata Steel's Cold Rolling Mill complex, including observations about the cold rolling process, maintenance practices, and electrical systems used. Key developments at Tata Steel include switching to more advanced steelmaking technologies, building new facilities like sinter plants and cold rolling mills, and ongoing improvements to increase efficiency and yields.
Aluminium technologies week 12
Continuous casting of aluminum offers substantial savings over traditional casting and rolling processes. It allows the melt to be directly formed into thin strip that can be cold rolled to final gauge without hot rolling. However, it is only suitable for alloys that can solidify rapidly through the caster. Properties of continuously cast strip include very fine dendrites, reduced segregation, and a fine grain size due to the high solidification rate. The strip must then be cold rolled and heat treated. The Properzi caster is important for continuously casting aluminum wire bars which are then hot rolled into coilable stock. Common applications for rolled aluminum include transportation, packaging, and building/construction.

piston material selection
This document discusses materials used for pistons in engines. It describes that pistons are cylindrical components that slide back and forth in the engine cylinder. The most common piston materials are cast iron and aluminum alloys. Cast iron pistons are used for lower speed engines while aluminum alloy pistons are used for higher speed engines due to their lighter weight. Aluminum alloys have advantages over cast iron like higher thermal conductivity and lower density, making them a suitable material for pistons.
effect of alloying elements in steel
This document discusses the effects of various alloying elements in steel, including manganese, silicon, chromium, molybdenum, vanadium, and copper. Manganese increases strength and hardness while promoting an austenitic structure. Silicon improves electrical and magnetic properties as well as oxidation resistance. Chromium increases corrosion and oxidation resistance along with hardenability. Molybdenum improves creep resistance and reduces temper brittleness. Vanadium stabilizes carbides and increases strength while maintaining ductility. Copper increases strength and corrosion resistance. Each of these elements is added in specific amounts to steel to achieve desired properties for applications like gears, shafts, springs, and architectural materials.
Fatigue & Residual Stresses on Aluminum alloys of Engine Block
1) The document discusses fatigue and residual stresses in aluminum alloys used for engine blocks. It aims to reduce the weight of engine blocks by using aluminum alloys instead of cast iron. [2) Heat treatment solutions like T6 and T7 are explored to address fatigue issues, while solution heat treatment is applied to reduce residual stresses. Experiments involve applying different heat treatments and measuring their effects. [3) Key results found that solution heat treatment at 470C for 5 hours completely relieved residual stresses, and heat treatment improved fatigue life by reducing defects that initiate cracks.
Steel Making: Lecture deoxidation
The document discusses the process of deoxidizing steel. During steelmaking, oxygen dissolves into the liquid steel but not in the solid steel. Deoxidation or "killing" of steel refers to reducing the excess oxygen content before casting to prevent blowholes and inclusions. This is typically done through precipitation deoxidation using elements like aluminum, silicon, and manganese that have a higher affinity for oxygen than iron and form stable oxides. These deoxidizers are chosen based on factors like stability, deoxidizing ability, oxide melting point and density. Aluminum is the most powerful deoxidizer but its oxide alumina must be modified to remain liquid during casting.
Galvanized Steel Manufacturing Process
1. The document describes the manufacturing process for galvanized steel frames used in power transmission towers. It involves planning and design, obtaining raw materials, fabrication which includes cutting, marking, drilling and other machining, and a final galvanization process to prevent corrosion.
2. Key steps in the fabrication process are cutting the steel angles to size, marking them according to drawings, drilling holes using precision machines, and bending frames into shape. Coolants are used to prevent overheating during machining.
3. The galvanization process provides corrosion protection by coating the fabricated steel frames with zinc via hot-dipping. Zinc corrodes more slowly than steel, protecting the frames for decades in harsh environments.
Automotive Applications of Welding Technology – A Study

Hot and cold working process, drawing tube, wire and spinning
The document discusses various bulk deformation processes used to shape metals, including hot working, cold working, drawing, and metal spinning. Hot working involves shaping metals above their recrystallization temperature using processes like rolling, forging, and extrusion. Cold working shapes metals below the recrystallization temperature through drawing, bending, and squeezing, increasing strength but decreasing ductility. Drawing is used to produce wires, rods, and tubes by pulling the metal through a die to reduce its size. Metal spinning forms axisymmetric parts by pressing a rotating workpiece against a mandrel using a tool.

ABSTRACT:
In this paper, the concept studied is hot forged from a bimetal
billet, which is a steel tube press fit with a solid aluminum
core and welded shut with steel end caps. For the experimental
part of the studies Al 7075 was selected as the core material
due to its high strength to weight ratio and 1020 steel was
selected because of its availability as a tube. Induction heating
was selected as the heating method for bimetal forging. This
is due to the ability of induction heating to rapidly heat the
steel layer. Successful bimetal forging of a closed vessel
requires the steel layer to be in the austenite phase prior to the
aluminum reaching high temperatures to prevent
compromising the weld seams. Modeling of the induction
heating process is complex due to the dimensional movement
of components during the process. A method was developed
to accurately model the induction heating process and predict
power requirements. The method will be described and the
results of the models will be compared to experimental
findings. The forming process will be discussed in another
paper at the conference. The simulation presented is for solid
state forging of a steel aluminum billet, but the method for
modeling the process is the same for hot hydroforging or other
material combinations.

This document provides a comparative study of diode and thyristor rectifiers used in aluminum smelters. It discusses the rectification technologies used in aluminum production and describes the diode and thyristor rectifier systems. The document then analyzes and compares the two rectifier types based on several key parameters: current harmonics, AC/DC conversion efficiency, power factor, and costs. Specifically, it examines data collected from two pot lines (one using each rectifier type) at Hindalco's aluminum smelter in Renukoot, India. The analysis shows that the thyristor rectifier produces slightly higher current harmonics but has a higher average conversion efficiency and less variation in efficiency compared to the diode rectifier.
Recycling copper rotors
This document discusses the recycling of copper rotor motors (CRMs) used in electric motors. It states that CRMs can be recycled within existing copper recycling processes to achieve almost 100% recovery of copper in a highly purified state, and an iron-silicon slag suitable for construction. The recycling process involves sorting CRMs from other metals, smelting to separate copper and iron, and electrolytic refining to produce high purity copper and valorize other metals.

Understanding User Needs and Satisfying Them
https://www.productmanagementtoday.com/frs/26903918/understanding-user-needs-and-satisfying-them
We know we want to create products which our customers find to be valuable. Whether we label it as customer-centric or product-led depends on how long we've been doing product management. There are three challenges we face when doing this. The obvious challenge is figuring out what our users need; the non-obvious challenges are in creating a shared understanding of those needs and in sensing if what we're doing is meeting those needs.
In this webinar, we won't focus on the research methods for discovering user-needs. We will focus on synthesis of the needs we discover, communication and alignment tools, and how we operationalize addressing those needs.
Industry expert Scott Sehlhorst will:
• Introduce a taxonomy for user goals with real world examples
• Present the Onion Diagram, a tool for contextualizing task-level goals
• Illustrate how customer journey maps capture activity-level and task-level goals
• Demonstrate the best approach to selection and prioritization of user-goals to address
• Highlight the crucial benchmarks, observable changes, in ensuring fulfillment of customer needs
