Metal treatment

To comply with end product specifications, molten aluminium must first be treated to remove impurities. To this end, the metal must go through various aluminium refining processes, obviously with a different piece of specialized equipment for each type of treatment.

  • The TAC (Treatment of Aluminium in Crucible) is used for sodium, calcium and lithium removal in the crucible. The TAC can be used together with an automatic skimmer to remove the bath material and the dross.
  • The RFI or RGI (Rotary Flux or Gas Injector) is used as a furnace treatment process for sodium and calcium removal as well as inclusion removal.
  • The DBF (Deep Bed Filter) is used for inclusion removal in the production of high quality products.
  • Finally, the ACD (Aluminium Compact Degasser) is used for aluminium degassing, sodium and calcium removal as well as inclusion removal.
