Direct Reduced Iron Industrial Efficiency Technology

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.
