STEEL MAKING

Major Equipment
The two Steel Melt Shop, SMS I & SMS II, comprises of Ultra High Power- Electric Arc Furnace, Argon Secondary Metallurgy Converter, LRF (Ladle Refining Furnace). SMS I is equipped with a continuous slab caster while SMS II is equipped with twin strand bloom caster. In addition to above SMS I is also equipped with VOD (Vacuum Oxygen Decarburisation) unit to produce steel with low inclusion and gas content. The present installed capacity of both SMS put together is 550,000 MT per year.The Slabs are subjected to surface conditioning in a slab grinding section. The Slabs are then Hot Rolled into HR Coils in Steckel Mill, which are then used to produce HRAP No1 Coils and Plates. HR coils are transferred to Cold Rolling Unit, to produce CR Coils and Sheets. The Blooms are hot rolled in Tandem Strip Mill to narrow coils and flat bars. . In addition, special steels like razor blade steel is cast into ingots which are subsequently forged to slabs & rolled in tandem strip mill.

Process

The production of stainless steel begins with melting of ferrous scrap and ferroalloys in UHP Electric Arc Furnace, followed by secondary refining in AOD/VOD units. The liquid steel thus obtained, is cast into slabs in a continuous slab caster with Auto Mould Level Control (AMLC) System. JSL produces stainless steel in 200, 300 & 400 series. Further the on-going efforts of a dedicated R&D Team along with Operations and Quality Assurance department are constantly innovating in fields of cost reduction, product development and addition of niche products such as Duplex Stainless Steel, Controlled expansion alloys as like INVAR-36 and Special Finish Cold Rolled Stainless Steel and Stainless Steels for critical applications.
