milling of direct reduced iron

  • Direct-Reduced Iron - an overview ScienceDirect Topics

    Jan 05, 2012  In direct reduction the ore is heated to temperatures below its melting point. Direct energy requirements per net ton of direct reduced iron are in the order of 10,000 MJ. The product is 90 to 95% metallized and hence is suitable as a charge in blast, basic oxygen, and electric arc furnaces.

    Direct-reduced iron has about the same iron content as Pig Iron, typically 90–94% total iron (depending on the quality of the raw ore) as opposed to about 93% for molten pig iron, so it is an excellent feedstock for the electric furnaces used by mini mills, allowing them to use lower grades of scrap for the rest of the charge or to produce higher grades of steel.

    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.
