Assembles of Refining Flux:
- Refining Flux
- Refining Jar
Applications for refining flux:
AdTech’s refining flux is white with slightly gray powdery fine particles. Main ingredients are chloride and villiaumite, together with other compounds. After appropriate heat treatment and screening, it turns to uniform size, which is conducive for transferring in refining jar with(N2 or Ar) gas as carrier to the bottom layer of molten aluminum. Through physical and chemical changes in the molten aluminum, numerous small bubbles are formed and fully contact with molten aluminum, separating hydrogen and other harmful gases. At the same time, adsorbing and fusing compounds contained in the refining flux can strongly adsorbing and fusing oxide and float, attaching together to the bubbles, with the rise of the bubbles and being brought to the surface of molten aluminum, so as to achieve the degassing and deslagging purpose of purification. Both environmentally friendly and economically, purifying with AdTech’s refining flux meets the requirement of high value-added & high-tech performance aviation, transportation and other aluminum alloy precise casting production, such as computer hard drive, micron-sized aluminum foil raw material, PS baseboard for printing, canning materials, fan blades for turbojet engine, etc.

Remove packaging, put flux into the spray equipment, flux goes through the spray jar with N2 or Ar gas as carrier, spraying evenly in two times to molten metal. Make sure the nozzle outlets as close to bottom layer of molten metal as possible, move the nozzle back and forth, so that flux fully contact with molten aluminum. Then refine the molten metal with N2 or Ar gas in turns at the bottom layer for 20 minutes.
