Rn Technology For Prdution Ofsponge Iron

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 …
