Melt Treatment - Drossing, Covering & Cleaning

 End to End Offering in Aluminium Casting Process

COVERAL fluxes are suitable for covering, cleaning and drossing applications in aluminium foundries. They reduce oxide formation and build-up on furnace walls, help to remove non-metallics from the melt, reduce the aluminium content of dross and facilitate removal of dross. Fluxes are supplied in granular or powder form. A wide range of fluxes are available in powder and granular form for manual or FDU application. Granular products are dust free and more effective than powder fluxes, allowing addition rates to be reduced. COVERAL FREE are sodium free and COVERAL PURE are sodium and calcium free recipies. COVERAL ECO fluxes produce dry ash-like dross that is eaasily separated from the liquid metal and have been specially developed to be environmentally friendly.

CLEANING, DROSSING FLUXES

Cleaning fluxes are designed to remove non-metallics from the melt by trapping the oxides particles as they float out. 

Covering and drossing fluxes are used to form a molten layer to protect the melt from oxidation and hydrogen pick-up. They agglomerate the oxides and non-metallic materials from the melt, cleaning the melt and forming a good metal-free dross which can easily be removed.
