General Introduction of 2# Flux

  • It used as a washing and melt covering for crucible, ladle and other tools for smelting and casting mag and mag alloy with the features of good wetting ability with the molten metal and tools.
  • The density of flux is less than the magnesium melts in the molten state, with the function of covering and fire extinguishment. With excellent
  • performance refining function on crude magnesium.
  • The cleaned tools is not easy contaminated on the melt and pouring metal melt.
It played a significant role on improving the quality of ingot and casting, reduce metal loss and increase the service life of the tools.

Function of 2# Flux

The combination of magnesium and potassium chlorides provides the low melting eutectic,while the fluoride provides the surface wettability and chemical reactivity with magnesium oxide to cause sufficient removal. MgO increases the viscosity of flux. The barium compound provides the density requirement for the salt to effectively mix with the magnesium and then settle out at the bottom of the crucible.
