Direct Reduced Iron (DRI), also known as Sponge Iron, offers an alternative steel production route to BFBOF and ScrapEAF 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.
