Its advantages as a iron product and diluent for impurities, introduced with scrap, are well documented. DRI is also known as sponge iron. It refers to porous iron produced by the direct reduction (DR) process. It is the second most viable source of iron used in steelmaking after hot metal which is produced in the blast furnaces (BF).

The billet produced within the country is made from 75 percent sponge iron and 25 percent scrap iron. The billet produced this way is rolled and made into iron rods. Agrawal said Rs36 billion had been invested in a dozen and a half such plants, which employ 5,000 people and produce around 2.3 million tonnes of iron rods annually.

Sponge iron is obtained by direct reduction (elimination of oxygen) of iron ore, without melting it in a blast furnace. Sponge iron is an intermediate iron product used as a substitute for steel scrap while producing steel through the electric induction furnace route, the entire production of sponge iron is consumed in-house for the manufacturing of MS Billets.

The metallic iron in this process is produced by the reduction of iron oxide below the fusion temperature of iron ore (1535 deg C) by utilizing carbonaceous material present in the non-coking coal. As the iron ore is in direct contact with the reducing agent throughout the reduction process, it is often termed as direct reduced iron (DRI).
