Visa Steel : Products : Pig Iron

VISA Steel has established a 250 cubic metre Blast Furnace with a capacity to produce 225,000 TPA Pig Iron in 2005. The Company commissioned the Blast Furnace within 11 months of being a Greenfield site, which was a record. The Blast Furnace, with state-of-the-art technology from SMS Demag/TRF, has turbo blowers and hot blast stoves which ensures a higher productivity and improved quality parameters.

Liquid Hot Metal produced through reduction of the Iron Ore in Blast Furnace, using coke as a reductant, fluxes and energy, 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.

PigIron comprises three main types: BASIC PIG IRON, used mainly in electric arc steelmaking, 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.

Pig iron contains at least 92% Fe. Other constituents are typically:

Basic Pig Iron

3.5-4.5% Carbon, <1.5% Silicon, 0.5-1.0% Manganese, <0.06% Sulphur, <0.12% Phosphorus

Foundry Pig Iron

3.5-4.5% Carbon, 1.5-3.5% Silicon, 0.5-1.0% Manganese, <0.06% Sulphur, <0.12% Phosphorus

Nodular Pig Iron

3.5-4.5% Carbon, 1-2% Silicon, <0.2% Manganese, <0.025% Sulphur, <0.08% Phosphorus

Over the years, VISA Steel has established its presence in both indigenous and international market and its Pig Iron has been widely accepted in all market segments.
