iron making by corex process

The Corex Process Part-1 | Right Steel

The most interesting feature of the Corex process is the separation of iron reduction and smelting operations into two separate reactors, which are reduction shaft and melter-gasifier, therefore it is a two-stage process. The Process. The Iron ore is directly charged into the reduction shaft along with limestone and dolomite additives.
