ABSTRACT:
Static bed type iron oxide reducing apparatus comprises reduction furnaces and cooling chambers respectively associated with the furnaces. Iron oxides are charged into the furnaces and reducing gas is applied to the raw materials to carry out a reducing reaction. After the iron oxides in the furnace have been metallized to a sufficient level, they are transferred to the cooling chamber to be cooled therein.
