Abstract

The invention discloses a reduction and refining integrated smelting system. The reduction and refining integrated smelting system comprises reduction tanks, a vacuum unit, a cooling crystallization unit, an argon gas protection unit and a magnesium liquefaction collection unit. Insulation blocks are arranged inside the upper portions of the reduction tanks, reduction tank cooling water sleeves are arranged outside the upper portions of the reduction tanks, and upper openings of the reduction tanks are sealed with reduction tank upper covers. The reduction tanks are connected to the cooling crystallization unit through a magnesium vapor pipe. The cooling crystallization unit comprises a crystallizer heater top cover, a sodium potassium plate, a heater and a crystallizer. The vacuum unit comprises a vacuum pipeline and a vacuum pump. The argon gas protection unit comprises an argon gas pipeline and an argon gas supply device. The magnesium liquefaction collection unit includes high temperature resistance ceramic valves and a magnesium liquid pipeline, the magnesium liquid pipeline is connected to the heater, and the high temperature resistance ceramic valves are located at an inletof the magnesium liquid pipeline and an outlet of the magnesium vapor pipeline. The reduction and refining integrated smelting system solves the problems of low magnesium recovery rate, serious pollution, dangerous operating environment and low quality of magnesium ingots in the prior art.

Description

technical field [0001] The invention belongs to the technical field of metal magnesium smelting, and in particular relates to a reducing and refining integrated smelting system, which realizes the refining and ingot casting of crude magnesium metal on the premise of meeting the requirements of energy saving and environmental protection. Background technique [0002] The crude magnesium (crystalline magnesium) obtained by the Pidgeon method (vacuum silicothermal method) contains a lot of metal impurities and non-metallic impurities, which makes the crude magnesium (crystalline magnesium) bulky, loose, difficult to keep, store, and transport, and these metals Impurities will form a Jafani battery with magnesium to undergo electrochemical corrosion. Magnesium acts as an anode, and metal impurities such as iron and nickel act as a cathode to accelerate the corrosion of magnesium. Therefore, crude magnesium must be refined to meet the requirements of direct industrial use. [00...
