METHOD FOR MANUFACTURING PARTIALLY CARBONIZED COAL BRIQUETTES, APPARATUS FOR MANUFACTURING PARTIALLY CARBONIZED COAL BRIQUETTES, AND APPARATUS FOR MANUFACTURING MOLTEN IRON

摘要

Provided are an apparatus and method for manufacturing molten iron. According to the present invention, the apparatus for manufacturing molten iron comprises: a multistage fluidized bed furnace for reducing iron ore powders to obtain reduced iron powders; a high-temperature compacting unit for compressing the reduced iron powders to prepare a high-temperature compacted iron; at least one crusher for crushing the high-temperature compacted iron to have uniform particle size; a first conveying unit for conveying the crushed high-temperature compacted iron; and a melting furnace for melting the conveyed high-temperature compacted iron by combusting fine iron ores or lump coals, and for supplying a reduction gas produced in the furnace to the fluidized reduction furnace. The apparatus further comprises at least one compacted iron storing unit for storing some of the crushed high-temperature compacted iron. According to the present invention, molten iron can be stably and effectively manufactured.
