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 ...
