PURPOSE: A thermal reduction device for manufacturing magnesium with temperature controlling units is provided to improve the efficiency of separating magnesium and alkali metal while improving the efficiency of collecting magnesium. CONSTITUTION: A thermal reduction device for manufacturing magnesium includes a thermal reduction furnace, a thermal reduction reaction pipe (20), condensers (30), and temperature controlling units (40,50). The thermal reduction furnace heats a green compact briquette in which calcined dolomite, ferrosilicon, and fluorite powder are mixed. The green compact briquette is inserted into the thermal reduction reaction pipe, and the thermal reduction reaction pipe is heated by the thermal reduction furnace. The condensers condense the magnesian steam generated in the thermal reduction reaction pipe. The temperature controlling units controls the inner temperatures of the condensers. |
