DRI production | International Iron Metallics Association

DRI production. Direct reduction of iron is the removal of oxygen from iron ore or other iron bearing materials in the solid state, i.e. without melting, as in the blast furnace. The reducing agents are carbon monoxide and hydrogen, coming from reformed natural gas, syngas or coal. Iron ore is used mostly in pellet and/or lumpy form.

On the one hand, the coke serves as a source of energy. On the other hand, carbon monoxide is released when the coke is burnt. This in turn serves as a reducing agent for the process. It is used to generate the heat in the blast furnace to enable the reduction of iron ore to pig iron. Temperatures far above 1500 °C are generated in the process.
