JSW ISPAT's sponge iron is manufactured at one of the most efficient Sponge Iron plants in the world. The plant has been certified for ISO 9001:2008 and ISO 14001:2004. Sponge Iron Also called Direct-reduced iron (DRI), is produced from direct reduction of iron ore (in the form of lumps, pellets or fines) by a reducing gas produced from natural gas. The reducing gas is a mixture majority of Hydrogen (H2) and Carbon Monoxide (CO) which acts as reducing agent. The product becomes spongy due to removal of oxygen and thus called sponge iron.

Steel is normally produced to meet the specific application-oriented criteria, keeping in view its chemical composition and mechanical properties. However, residuals influence the character of steel, including 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 from one supplier to another, but there remains a grouping or proportion of non-refinable metallic elements such as copper, tin and nickel, among others, upon which a maximum limit is placed for the best quality results. In the case of Ispat Hi-Q Sponge Iron, all these elements come across in traces only, and its chemical composition by and large, remains consistent, enabling the users to produce the best quality steel.

DRI is an excellent energy efficient substitute for steel scrap for making special steel at Conarc furnace to the tune of 30 -35% along with Pig Iron and contains no tramp elments like Cu, Sn, Sb, Cr, Pbwhich are harmful to final product quality.
