VISA Steel has established a 250 cubic meter Blast Furnace with a capacity to produce 225,000 TPA Pig Iron in 2005. The Company commissioned the Blast Furnace within a record time of 11 months as a Greenfiled Project. The Blast Furnace, with state-of-the-art technology from SMS Demag/TRF, has turbo blowers and hot blast stoves which ensure a higher productivity and improved quality parameters.
Most of the Liquid Hot Metal produced through reduction of the Iron Ore in Blast Furnace, using coke as a reductant, fluxes and energy, is transferred to the SMS for production of Special Steel. Any surplus is cast in moulds leading to production of solidified pieces of Pig Iron having weight of around 8-10 Kg.
With its defined and closely controlled specification and the absence of metallic impurities, pig Iron is a reliable and consistent charge material for both electric steelmaking and ferrous castings production.
Pig Iron comprises three main types: BASIC PIG IRON, used mainly in electric arc steel making, FOUNDRY PIG IRON used in mainly in the manufacture of grey iron castings in cupola furnaces, and NODULAR PIG IRON (SG GRADE) used in the manufacture of ductile iron castings.
