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.

A cost comparison Production and smelting of prereduced

A cost comparison Production and smelting of prereduced

The major capital expenditure in a plant to make prereduced pellets is for kilns and coolers. Other items, beyond those required for conventional pellets, such as reductant bins and conveyors, add little to the depreciation charge per ton of product. Prereduced pellet plants cost more per product ton than those for oxide spheres largely because there is more iron in the metallized pellets.
