APPARATUS AND A METHOD FOR MANUFACTURING REDUCED IRON BY REDUCING IRON ORE USING HYDROGEN

摘要

PURPOSE: An apparatus and a method for manufacturing reduced iron are provided to minimize the amount of pollutants discharged by reducing iron ore using hydrogen in a reduction furnace.;CONSTITUTION: An apparatus for manufacturing reduced iron comprises a reduction furnace(110), a hydrogen reduction unit(112) which is installed in the reduction furnace to reduce iron ore using hydrogen, a crushing unit(130) which crushes the reduced iron discharged from the reduction furnace, and a separating unit(140) which separates the crushed reduced iron into slag and metal. The reduction furnace comprises a preheating part(111), a reheating part(113) reheating iron ore discharged from the hydrogen reduction unit for reheating, and a melting part(114) changing the reheated iron ore into the final reduced iron through melting reaction.;COPYRIGHT KIPO 2013
