Direct Reduction Ironmaking | SpringerLink
Direct Reduction Ironmaking. It is the non-coke ironmaking process in which a gaseous, liquid, or solid reductant is used to reduce the iron ore into metallic iron in a temperature less than the ore softening temperature. The product is direct reduction iron which is an ideal raw material for producing high-quality steel and clean steel.
