Abstract

903,897. Reducing metallic oxides. KELLOGG CO., M. W. Sept. 22, 1960 [Oct. 5,1959], No. 32568/60. Classes 72 and 82 (1). A method of reducing granular metallic oxides comprises introducing into a molten metal bath a reducing agent and injecting the granular metallic oxide into the molten metal whereby the oxide is reduced and the molten metal formed is removed. As shown, applied to the reduction of oxidic iron ore, a bath 12 of pig iron is formed and oxide ore mixed with a liquid, solid, or gaseous, carbonaceous reducing agent and slag forming materials is introduced below the metal surface through a lance 11. Air from a regenerator 15 is fed to the same end of the furnace, part of this air being used to burn oil from a burner 18 and the remainder to burn carbon monoxide produced by the reaction between the reducing agent and the ore. When the air is changed over to the other end of the furnace, the ore and other additions are injected through a lance 26. Metal is removed from the furnace through an opening 23 and slag through an opening 24. When the reducing agent does not produce large quantities of gas, e.g. coke, it may be added at the centre of the furnace only. Chromium and manganese oxides may be reduced to metal by the process.
