PURPOSE: A thermal reduction device with a multi-stage condenser for manufacturing magnesium is provided to improve the efficiency of separating magnesium and alkali metal, to improve the efficiency of collecting magnesium, and to apply the multi-state condenser to a thermal reduction reaction pipe for several kinds of metal. CONSTITUTION: A thermal reduction device with a multi-stage condenser for manufacturing magnesium includes a thermal reduction furnace (10), a thermal reduction reaction pipe (20), a lower condenser (30), and an upper condenser (40). The thermal reduction furnace is a heater heating a green compact briquette in which calcined dolomite, ferrosilicon, and fluorite powder are mixed. The thermal reduction reaction pipe is composed of a cylindrical retort and a cooling member. The lower condenser condenses the magnesian steam generated in the thermal reduction reaction pipe. The upper condenser condenses the alkali steam generated in the thermal reduction reaction pipe. |
