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.
