Multiple Hearth Furnace Direct Reduced Iron

The development of direct reduced iron (DRI), also called sponge iron. Defining DRI ‘Reduced iron’ derives its name from the chemical change that iron ore undergoes when it is heated in a furnace at high temperatures in the presence of hydrocarbon-rich gasses. ‘Direct reduction’ refers to processes which reduce iron.DirectReduced Iron an overview ScienceDirect Topics. Direct reduction DR is defined as any process in which metallic iron is produced by the reduction of iron ore at temperatures below the iron melting point The product of a DR process is called direct reduced iron DRI The major consumers of DRI are the smaller steel mills which use DRI to dilute the residual elements.Reduced iron derives its name from these processes, one example being heating iron ore in a furnace at a high temperature of 800 to 1,200 C in the presence of the reducing gas syngas, a mixture of hydrogen and carbon monoxide. DRI, direct reduced iron, is produced through the removal (reduction) of oxygen from iron ore in its solid-state.Direct reduced iron (DRI), also called sponge iron, is produced from the direct reduction of iron ore (in the form of lumps, pellets, or fines) to iron by a reducing gas or carbon produced from natural gas or coal. Its main use is as raw material feedstock for electric furnaces in mini mills, where DRI can be used as a scrap substitute.
