Salem Steel Plant
steel plant at Salem for the production of steel and strips of electrical, stainless and other special and mild steel.
The major facilities at the plant include
· Steel Melting Shop
· Cold Rolling Mill Complex
· Hot Rolling Mill Complex
· Stainless Steel Blanking Line
SSP specializes in the production of cold rolled stainless steel in the form of coils and sheets.
The raw materials are imported and also supplied by alloy steel plant in Durgapur The steel
melting shop's annual capacity is 1,80,000 tonnes of slabs per annum. The hot-rolling mill and
cold-rolling mill have capacities of 3,64,000 and 66,600 tonnes per annum.
The steel melting facilities comprise ultra-high power Electric Arc Furnace, Argon Oxygen Decarburising (AOD) Refining Unit with Level-II automation, Ladle Furnace & Continuous Casting machine with state-of-the-art technology to produce premium quality stainless steel slabs. The plant is facilitated with Hot Rolling Mill which can roll both stainless & carbon steels & the mill caters mainly to the input needs of stainless steel coils for the cold rolling mills. Special grades of carbon steels other than structural steels are also rolled from the facility includes weathering steels, high strength low alloy steels, etc., which are extensively used in industrial sectors.
Hot Rolling Mill complex is equipped with walking beam reheating furnace, primary descaler, 4-hi reversing roughing mill, 4-high reversing Steckel Mill, down coiler, laminar cooling & roll grinding machines, procured from world renowned suppliers. The Steckel Mill, the mother unit of hot rolling with level-2 automation is provided with hydraulic gauge setting & automatic gauge control. The continuously variable crown (CVC) controls the profile & flatness by roll shifting & work roll bending system provide additional fine control of flatness of the strip.
Cold Rolling Mill complex is equipped with the most modern stainless steel production lines, sourced from leading manufacturers of the world. Coil build up line, bell anneal furnaces continuous annealing & pickling lines, Sendzimir mills, skinpass mill, strip grinding line, slitting & shearing lines to produce coils /sheets with precise dimensional tolerance & flatness with superior metallurgical characteristics.
Ferritic & martensitic stainless steel are annealed/softened at bell annealing furnaces & austenitic stainless steel is annealed/softened & descaled in continuous annealing & pickling lines using Ruthner neutral electrolytic pickling process & mixed acid pickling for superior surface finish. The coils are rolled in 20-high computerized Sendzimer mills to required dimensional tolerances. A 2-high skin pass mill with elongation control & constant hydraulic roll force system ensures a product of bright finish & high flatness. A shearing line with precision roller levelers, electronic flying shear & vacuum piler facilitates defect-free piling of the leveled cut sheets. Coils of narrow width & smaller weight are produced by a precision slitting line equipped with latest features like in feed car, grip feed device, tension pad & interchangeable slitters.
