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.

Operation Strategy :- Corporate Mission

JSW Steel Limited (“JSW”) believes in creating sustainable growth while balancing utilization of natural resources and social development in its business decisions.

It also believes in pursuing its business objectives ethically, transparently and with accountability to its stakeholders across the value chain.

JSW is committed to promote integrated responsible behavior and value for social and environmental well-being.

Business Strategy Our sustainable & inclusive growth is not just about the numbers but

improving the quality of the lives of the individuals and communities at large For JSW Steel the incremental growth strategy has worked better than the Big-

Bang approach and this is what they are getting back to when plans for new projects are not working out,” said an analyst with an international brokerage who did not want to be named.

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).

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.

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.

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.

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.

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.

Ladle Heat Furnace

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

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

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

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.

Corex Process Benifits

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

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.
