SP FLUX – 56 ( Dross Recovery Flux)

SP FLUX – 56 is White Colour powder made from Salts of Sodium & Fluorides recommended for dross treatment i.e. for removing the Aluminum Metal from hot dross.

After the treatment of Aluminum liquid metal dross is removed. At the time of dross removing the some aluminum metal comes out along with the Dross. For the recovery of Aluminum metal the dross should be treated with the high exothermic flux. The said flux reacts with the dross & seperates the Aluminum Metal . This treatment should be done in separate vessel or crucible.

SP FLUX – 56 is recommended for the recovery of Aluminum metal from the dross. covering and drossing operation. SP FLUX – 11(L) form a layer over liquid Aluminium which acts as a barrier between liquid Aluminium and atmosphere. By this SP FLUX – 11(L) prevents the excessive dross formation and reduces the loss of metal & gas pick-up. Meanwhile exo-thermic reaction of SP FLUX – 11(L) influences easy removal of Metal free dross and removal of non-metallic inclusion from liquid metal.

For Crucible Furnace : 0.5 - 1% of metal charge
(Higher % recommended for loose and uncleaned scrap) For Reverberatory Furnace :
125- 150 gm/ Sq. ft. of liquid pool area.

  • It is most important to keep the cover of flux over liquid metal through-out melting practice. For this it is advised to apply SP FLUX – 11(L) in 2/3 stages.
  • Take requisite quantity of SP FLUX-11(L) as recommended.
  • Add 1/3rd quantity of total required flux in the beginning i.e. at semi-liquid stage. Keep the layer intact to prevent initial Oxidation of Liquid Aluminium .
  • Add second part in the middle stage i.e. approximately 50% of total melt.
  • When melt is ready; add the remaining quantity at a temperature 700oC, allow to stand for 5-6 minutes. Rabble the Dross for 2-3 minutes with skimmer.
  • Put-on the furnace wait for 5 minutes more, this activates the flux, heating the Dross and helps good metal separation.
  • Remove the metal free dross with help of perforated skimmer.
