Abstract: A method of cold starting a molten bath-based direct smelting process for producing molten iron in a vessel (3) is disclosed. The method includes a step of preheating the vessel before supplying solid feed materials into the vessel. The method also includes a subsequent step of supplying an oxygen-containing gas and solid feed materials including material for forming slag, iron-containing feed material, and carbonaceous material into the vessel and generating heat and forming a bath of molten material that includes molten iron and molten slag in the vessel. This step includes supplying feed materials to promote formation of molten slag over molten iron in an early stage of developing the molten bath.

Abstract: Un método y un aparato para producir hierro de reducción directa (DRI), por lo general, en forma continua, a partir de mena de hierro usando biomasa como una fuente principal de agente reductor en un horno de solera que tiene una zona de precalentamiento, una zona de reducción, y una zona de transición entre las zonas de precalentamiento y de reducción, donde la zona de transición está configurada para compactar el material de mena de hierro / biomasa transportado sobre el transportador, a medida que este se desplaza a través de la zona de transición, desde la zona de precalentamiento hasta la zona de reducción, de manera que se presenta un lecho de material más compactado, que resulta más adecuado para el procesamiento con energía de microondas en la zona de reducción.

Abstract: A method for producing direct reduced iron ("DRI") from iron ore and biomass is disclosed. The method includes heating a batch of iron ore and biomass in each oven chamber of a non-recovery batch oven by a combination (i) the thermal mass of a lining of the oven chamber and (ii) combustion of a fuel gas from at least one other oven chamber and at least partially reducing the iron ore and forming DRI. The method also includes discharging gases from the oven chamber through passageways in a wall and a floor of the oven chamber and further combusting combustible gases and transferring heat to the wall and the floor of the oven chamber as the gases move through the passageways. The method also includes discharging at least a portion of gases from the oven chamber, without passing the gases through passageways in the floor of the oven chamber, and using these gases as a fuel gas in subsequent combustion heating in other batch oven chambers when a first predetermined trigger point is reached. A non-recovery batch oven is also disclosed.
