Sponge Iron - an overview | ScienceDirect Topics

In the first step, iron ore is reduced to sponge iron in a shaft furnace by means of reducing gas. In the second step, the reduced iron is melted in the melter–gasifier vessel. Reducing gas (CO and H 2 ) used in the reduction shaft is supplied by gasification of coal by means of oxygen, forming a fixed or fluidized bed in the melter–gasifier.
