Direct Reduction Of Iron Ore Using Natural Gasnatural Iron Ore

Midrex© Process | Industrial Efficiency Technology & Measures

Midrex is direct reduction process using a shaft-reactor and is developed by Midrex/Kobe Steel. Iron ore pellets, lump iron ore or a combination of pellets and ore are reduced in a vertical shaft or reduction furnace to metallic iron by means of a reduction gas. The reducing gas is produced from a mixture of natural gas and recycled gas from the reduction furnace.

Direct Reduction Iron (DRI) furnaces are used to produce iron from iron ore oxides using natural gas. The furnace takes the iron ore in the form of spherical pellets and a mixture of hydrogen and carbon monoxide and produces reduced iron. Accurate estimation of the quality of the reduced iron is essential for proper control and efficient operation of the DRI furnaces.

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.
