Description
Technical Field
The utility model belongs to the technical field of the equipment of silicothermic process production magnesium metal, concretely relates to magnesium metal crystallization water jacket and crystallization device.
Background
The smelting method of the magnesium metal mainly comprises a thermal reduction method and an electrolytic method. Currently, ferrosilicon is generally adopted as a reducing agent for the thermal reduction method to remove dolomite [ magnesium carbonate calcium CaMg (C0)3)2]Magnesium oxide produced through a step such as calcination is thermally reduced to produce magnesium metal, and hence the method is also called a silicothermic method. The production process of the silicothermic process comprises the steps of crushing dolomite, heating and calcining by coal gas to obtain calcined dolomite (called calcined dolomite, the main components of which are magnesium oxide and calcium oxide), grinding by a ball mill, preparing and pressing balls by the calcined dolomite, fluorite powder and crushed and ball-milled ferrosilicon powder according to a proportion, then putting the balls into a reduction tank with a water jacket at the opening end, placing the reduction tank into a coal gas heating reduction furnace, putting the reduction tank into a crystallization device, vacuumizing and heating the interior of the reduction tank for reduction. Because the temperature of the water jacket is lower under the action of circulating water, magnesium steam reduced from the tank is crystallized in a crystallization barrel in the water jacket to form crystallized magnesium (crude magnesium), after the crystallization is finished, the crystallization barrel in the water jacket is taken out, the crystallized magnesium is taken out by a magnesium pressing machine, the crystallized magnesium is put into a refining furnace for refining, and the crystallized magnesium is cast into magnesium metal ingots (refined magnesium) with different specifications through a continuous casting machine.
