ABSTRACT:
Iron or steel products are produced from oxide ores in a unique process which utilizes air and regular coal as its primary energy source and wherein the ore is melted in a carbon dioxide zone for separation and absorption of the iron oxides into a slag which is transferred to a carbon-monoxide generating zone. In the latter zone the iron oxides are reduced to form the iron or steel product. Carbon monoxide containing flue gas from the latter zone is burned with air and utilized as a heat source in the carbon dioxide zone. Slag from the various unit processes is collected and used to preheat process air by either continuous operation or in a semi-continuous regeneration process. In both modes of slag preheating, flue gas is utilized to maintain the temperature of the slag bath and high temperature air preheating prior to the slag bath. The molten metal is refined by atomizing in slag or protective gas and may be formed into a sheet by extrusion through a slot-shaped orifice into a space defined between two perforated plates, with a protective gas injected through the perforations serving to support the metal sheet as it solidifies and cools. The thermomechanical treatment of the metal may be carried out by the simultaneous cooling and rolling in a protective atmosphere.
