2. About
 JSW Steel Ltd. The flagship company of over $11 billion JSW Group, JSW Steel is one
of India's leading integrated steel manufacturers with a capacity of 18 MTPA
 JSW Group’s foray into steel manufacturing began in 1982, when it set up the Jindal
Iron and Steel Company with its first steel plant at Vasind near Mumbai. The next two
decades saw significant expansion and several acquisitions, following the merger of
Jindal Iron and Steel Co (JISCO) and Jindal Vijayanagar Steel Ltd (JVSL) in 2005.
 Today JSW Steel has plants in six locations in India — Vijayanagar in Karnataka,
Salem in Tamil Nadu, and Tarapur, Vasind, Kalmeshwar and Dolvi in
Maharashtra.
 There global operations include a plate and pipe mill in the US. In order to securities
resources, the company has acquired mining assets in Chile, USA and Mozambique.

11. Beneficiation
 In the mining industry beneficiation or benefication in extractive metallurgy, is any
process that improves (benefits) the economic value of the ore by removing the
gangue minerals, which results in a higher grade product (concentrate) and a waste
stream (tailings).

12. Pelletizing
 Pelletizing is the process of compressing or molding a material into the shape of
a pellet. A wide range of different materials are pelletized including chemicals,
iron ore.

13. Sintering
 Sintering is the process of compacting and forming a solid mass of material by
heat or pressure without melting it to the point of liquefaction. Sintering happens
naturally in mineral deposits or as a manufacturing process used with metals,
ceramics, plastics, and other materials.

14. Blast furnace
 The blast furnace is a huge, steel stack lined with refractory brick, where iron ore,
coke and limestone are dumped into the top, and preheated air is blown into the
bottom. The raw materials require 6 to 8 hours to descend to the bottom of
the furnace where they become the final product of liquid slag and liquid iron.
The hot blast temperature can be from 900 °C to 1300 °C (1600 °F to 2300 °F)
depending on the stove design and condition.

15. HMDS
 The reagent transfer in the injection line is under dense flow conditions. ...
The process allows the use of several desulphurization reagents, such as lime,
calcium carbide and magnesium, which remove the Sulphur in the hot metal by
chemical reaction and convert it to the slag.

16. converter process
 Basic oxygen steelmaking (BOS, BOP, BOF, and OSM), also known as Linz–
Donawitz-steelmaking or the oxygen converter process is a method of primary
steelmaking in which carbon-rich molten pig iron is made into steel.

17. Ladle Heat Furnace

18. Cold Strip Mill(CSM)
 Cold rolling is accomplished by processing steel strip through a series of tandem
rolling mill stands. Each stand has vertically stacked rolls that are powered by huge
motors to impart high compressive stresses into the strip.
 Hot-rolled, pickled coils are fed into the cold rolling mill from an entry-end reel
and progressively reduced in thickness in each stand to achieve the final desired
thickness as the strip exits the last stand. After the last stand, the strip is recoiled

19. Hot Strip Mill(HSM)
 Hot rolled bands and sheets are primarily low carbon steels that are produced on
a Hot Strip Mill from slabs that have been thoroughly heated to a rolling
temperature of approximately 2300°F. Slab heating at this temperature
accomplishes several desirable end results, which include, surface scaling for
minor surface

20. Galvanizing
 Galvanization or galvanization (or galvanizing as it is most commonly called in that
industry) is the process of applying a protective zinc coating to steel or iron, to
prevent rusting. The most common method is hot-dip galvanizing, in which parts
are submerged in a bath of molten zinc

21. Corex-Green Technology to produce hot
metal
 JSW Steel is the first Indian Company to use the Corex
technology to produce hot metal. We went for this
technology although it was untested in Indian conditions due
to its benefits to the environment.
 The Corex Process is a smelting reduction process created
by Siemens VAI as a more environmentally friendly alternative
to the blast furnace. ... Unlike the Blast Furnace, smelting
reduction processes are typical smaller and use coal and
oxygen directly to reduce iron ore into a usable product.
 All metallurgical work is carried out in two separate process
reactors - the reduction shaft and the melter gasifier. Lump
ore, sinter, pellets or a mixture are charged into a reduction
shaft where they are reduced to direct-reduced iron (DRI) by
a reduction gas.

23. MORGAN technology
 Which producing high quality HYQST (High yield Quenched and Self tempered)
 Morgan Enhanced Temperature Control System
 Clean Steel – Sulphur and Phosphorus restricted to 0.005 – 0.035%
 Best Combination of strength and ductility – Yield Stress > 530 MPa; %Elongation >
18%
 Easy Weldability- due to low carbon equivalent. It can be easily butt-welded, lap-welded
and manual arc welding can also be done quite simply without any pre-heating
 Easy Bendability- due to its inherent microstructure with soft ferrite and pearlite core
 Higher Corrosion Resistance- due to its unique microstructure and absence of residual
stresses
 Higher Fatigue Resistance- due to a uniform and critically designed rib pattern
 JSW TMT PLUS bars are specially designed for earthquake prone zones and have
superior earthquake resistance. Its high UTS/YS ratio of 1.15 minimum ensures a higher
energy absorption capacity

24. DANIELI AUTOMATION
 The DMC2000 system cover the process and equipment control of bar and wire roll
mills, it can benefit from DANIELI AUTOMATION experience and know-how thanks
to systems designed for high productivity and quality of production.

26. ABB-FULLY INTEGRATED CONTROL SYSTEM
FOR JSW COLD ROLLING MILL
 Roll@xA Optimize - Make the right pass
 The Roll@xA Optimize software is a pass schedule planning and setup
calculation system incorporating a mathematical model for the reduction
process in a rolling mill.
 Based upon specified coil data such as alloy, strip width, entry and exit
thickness, the reduction is distributed optimally over several pass.
 The Roll@xA Optimize solution is fully inegrated in ABB's CPM4Metals
Collaborative Production Management System for rolling mills.
 The setup calculation determines all rolling mill preset values, for example for
roll force, position and flatness. The adaption module re-calculates and
continuously improves these preset values.
