Flux in the effects of the main ingredients 1, anhydrous magnesium chloride (MgCl2), MgCl2 at high temperature parts react with 02 and H20 in the air and melt surface to form HCL and H2 protective gas. Slow melt oxidation; MgC12 of the liquid melt Mg0, Mg3N2 inclusions have very good wetting ability and combined with Mg0 MgCl2.5MgO compounds. Thus has strong oxidation removal Central complex role. 2, potassium chloride (KCl), due to surface tension, viscosity KCl were smaller, it significantly reduces the surface tension and viscosity. 3, sodium chloride (NaCl): and MgCl2 and KCl form MgCl2-KCl-NaCl n. Increase in the density of its flux, and can be used to adjust the melting point. 4, calcium fluoride (fluorspar powder CaF2): used to increase the viscosity of flux refining performance of CaF2 have some solubility in MgCl2-KC1-NaCl n. Join CaF2 over this melted when dissolved in a molten salt mixture emerged CaF2 particles, greatly improving the viscosity of mixed salt. In addition, the CaF2+MgC12=MgF2+CaCl2 generates MgF2 solubility in chloride is very small, and its solubility does not change with temperature. MgF2 has the ability to combine with MgO and slag. 5, magnesium oxide (Mg01): used as a thickener flux, increase the viscosity of flux. 6, anhydrous barium of Qi (BaC12): has greater density at room temperature to 3.87, play a role in weight additive.
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.Packaging & Shipping
