flux for melting practice for magnesium alloys shenzhen chemicals

Application method:

    Flux refining including crude magnesium smelting and refining processes such as, temperature, static, electrically heated or gas heated Crucible Furnaces. Crucible Furnace shell welded steel plates, cylindrical Crucible containing magnesium placed in a cylindrical furnace refractory bricks. 1~2T Crucible capacity, by a boiler, steel or high quality carbon structure steel welded or cast into wall-thickness 20~40mm. Prior to refining, part of block-based fluxes and for preheating the Crucible bottom, then add the coarse magnesium and magnesium constant heating melt. To the molten magnesium reach the required level, that is from the Crucible along the 200mm. Set about refining magnesium melting temperature up to 973K, that is stirring molten magnesium into the refining fluxes for continuous operation 15min. Then after warming up to 1013~1023K static 10~15min, separation of flux and magnesium containing oxides and other impurities. In the process of refining, heat can be replaced, in order to prevent the loss of magnesium oxide and magnesium melt surfaced with the right amount of cover fluxes. When the temperature of molten magnesium fell to 983K, the Crucible into the overturned ladle and casting ingots in a continuous casting machine. Mold flux refining magnesium and this, according to the consumption of magnesium content standards for 1-3%, as metal burning, immediately thrown into flux.

Magnesium magnesium collection rate of flux refining 95%, to produce one ton of pure magnesium flux consumption: molten salt electrolysis of magnesium production when crude magnesium as a material, usually 16~30kg; thermal reduction process for magnesium production when crude magnesium as a material, usually 100~150kg.
