  • Direct Reduced Iron Industrial Efficiency Technology

    Direct Reduced Iron (DRI), also known as Sponge Iron, offers an alternative steel production route to BF BOF and Scrap EAF routes. In DRI, iron ore is reduced in its solid state unlike BF process where a liquid metal is formed during reduction. DRI can then be transformed to steel in electric arc furnaces. DRI production is common in Middle East, South America, India and Mexico.
