  • COREX Process Iron Making Iron Steel Review Industry

    In a nutshell, COREX is a coal based SR (smelting reduction) process of making hot metal or pig iron by direct use of non-coking coal. The outputs can be used either by integrated mills or EAF (electric arc furnace) mills. The process gasifies non-coking coal in a smelting reactor, which also produces liquid iron.

    Process. The Corex process consists of two main parts a Reduction Shaft and Melter- Gasifier [4]. The main reagents for the Corex process are iron ore, noncoking coal, and oxygen. [5] Unlike the Blast furnace the Corex process does not use a hot blast of nitrogen, thereby greatly reducing NOx gas emissions, but instead uses oxygen. In addition

  • Corex Process Industrial Efficiency Technology & Measures

    Corex is a smelting reduction process combining a melter gasifier with a reduction shaft. The process takes lump iron ore or pellets, non-coking coal, and oxygen as main inputs. Similar to the blast furnace process, the reduction gas moves in counter flow to the descending burden in the reduction shaft. Then, the reduced iron is discharged from the reduction shaft by screw conveyors and
