Sponge iron, also known as direct-reduced iron (DRI), is a form of metallic iron produced by reducing iron ore with carbon or other reductants at high temperatures, typically between 800-1200C. It's a crucial raw material in the iron and steel industry, serving as a substitute for scrap in certain steelmaking processes.
Here's a more detailed look:
Production:
Sponge iron is made by reacting iron ore (lumps, pellets, or fines) with a reductant, such as coal, natural gas, or hydrogen, at high temperatures.
Appearance:
The resulting product, DRI, has a porous, sponge-like structure due to the reduction process, hence its name.
Uses:
Sponge iron is primarily used in the production of steel, where it serves as a substitute for scrap in electric arc furnaces and induction furnaces.
Advantages:
Compared to traditional iron production in blast furnaces, sponge iron production offers advantages like higher purity, lower environmental impact, and the ability to utilize lower-grade iron ore.
India's Role:
India is a major producer of sponge iron, with a strong focus on utilizing its abundant iron ore deposits and adopting various reduction technologies.
Carbon-to-Iron Ratio:
The carbon-to-iron (C/Fe) ratio in sponge iron is typically between 0.44 and 0.48.
