ON THE DIRECT REDUCTION OF IRON ORE IN ROTARY KILN

Since in the rotary kiln the reduction of iron ore takes place topochemically5, the rate of oxygen removal from t single iron ore particle can be expressed as: of total oxygen removed froc the charge 1,ed, Hence, PCO PCO2/K, +1.-1/3-1.4 f-3 . ° * o Rate of Carbon Gasifications For temperature upto

Sponge Iron an overview ScienceDirect Topics

DRI, also known as sponge iron, is the product of reducing iron oxide in the form of iron ore and steel plant wastes into metallic iron, below the melting point of iron and typically in the range of 800–1200 °C. Iron oxide is charged into shaft furnace, rotary kiln, or fluidized beds in the form of pellet, iron ore
