Ispat Industries Limited [IIL] is one of the leading integrated steel makers and the largest private sector producer of hot rolled coils in India. Sponge Iron for producing Quality Steels is manufactured by the Ispat Industries Limited. The Sponge Iron plant of Ispat Industries Limited has been certified with ISO 9002 [1994] and ISO 14001 [1996]. Sponge Iron for producing Quality Steels is normally produced to meet the specific application-oriented criteria, while keeping in view the chemical composition and mechanical properties of the steel. The residuals influence the character of steel, internal cleanliness, surface finish and the processing conditions used during casting, hot rolling, cold rolling, heat treatment, and final finishing. For a given application, there may be many variations in steel chemistry, but in the case of Ispat Sponge Iron, the grouping or proportion of non-refinable metallic elements such as copper, tin and nickel, come across in traces only, and its chemical composition remains consistent. This enables it to produce quality steel. Range and Specifications of the Sponge Iron for producing Quality Steels manufactured by Ispat Industries Limited is as follows: Chemical Physical Fe-Metallic: 85 per cent minimum Size distribution: +30 mm: 5 per cent maximum Metallization: 92 per cent minimum -30mm to 4mm: 90 per cent Carbon: 1-2 per cent -4mm: 5 per cent maximum Sulphur: 0.02 per cent maximum Phosphorous: 0.04 per cent maximum SiO2+AL2O3+CaO+MgO: 3.5 per cent max.
