SP FLUX - GR

SP FLUX - GR is white'Colour granules made from Salts of Sodium & Fluorides recommended for covering and drossing operation.

Aluminium in liquid condition has higher affinity towards Hydrogen & Oxygen. Liquid Aluminium Alloys rapidly forms an Aluminium Oxide (Dross) film whenever Surface is freshly e*posed to Atmosphere. Excessive Formation of Aluminium Oxide (Dross) can be prevented by disturbing layer as little as possible which is difficult to maintain at Shop Floor.

SP FLUX - Gr forms a protective layer and the special exo-thermic properties of SP Flux Gr reduces the Dross formation & loss of Metal through Dross.

SP FLLX - GR is recommended for covering and drossing operation. SP FLIIX - Gr form alayer over liquid Aluminium which acts as a barrier between liquid Aluminiurn-and atmosphere. By this Sp FLUX - dr prevents the excessive dross formation and reduces the lois of metal & gas pick-up. Meanwhile exo-thermic reaction of Sp FLLIX - Gr influences easy removal of Metal free dross and rernoval of non-metallic inclusion from liquid metal.

For Crucible Furnace: 0.05 - O.l% of metal charge
(Higher o/o recommended for loose and uncleaned s-crap) For Reverberatory Furnace :
25- 50 gn/ 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 - Gr in 2/3 stages.
  • Take requisite quantity of SP FLUX- GR 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 700o c, allow to stand for 5-6 minutes. Rabble the Dross for 2-3minutes 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.
