Sponge Iron

The manufacturing process of Sponge Iron aims at reducing the oxygen content in iron- ore to make it porous.

The manufacturing process of Sponge Iron aims at reducing the oxygen content in iron- ore to make it porous. When observed under a microscope, it resembles a honeycomb structure, looking spongy in texture; from which it derives its name. The quality of Sponge Iron is ascertained by the percentage of metallisation or removal of oxygen, which is the ratio of metallic iron to the total iron present in the product. Sponge Iron manufactured by us is distinct due to its high metallic iron content and consistent chemical and physical characteristics. This provides furnace owners flexibility in preparing their charge to produce finer quality than what is possible using scrap only. Our dedicated customer support team functions to solve technical and operational problems faced by our customers. Our qualified and technical staff suggest ways and means to optimise Sponge Iron feed in furnaces and enhance steel output.
