corex process for pig iron

Comparative analysis of energy requirements of CO2 .1/4/2007· Pig iron and slag obtained from the Corex process are nearly identical in their composition and properties to the blast-furnace products. In comparison with blast-furnace technology, the Corex process requires less energy due to the fact that coal is coked within the process.Corex Process | Industrial Efficiency Technology & .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 ...
