SCOT-GR 2002 - Granulated Fluxes

Description

COVERFLUX GR 2002 is a granulated flux suitable for all types of Aluminium alloys with the exception of AlMg alloys where even a slight sodium pick-up must be avoided. It can be used for temperatures above 680 °C in sand, die and pressure die casting. COVERFLUX GR 2002 removes oxides and other non-metallic inclusions present in the melt, leaving a light and dry dross.

Benefits

COVERFLUX GR 2002 is fluoride free COVERFLUX GR 2002 has been specially developed to be environmentally friendly. It is dust free in use and emits low fume during application. Granulated fluxes can be used at reduced application rates compared to powder fluxes. Application Cleaning: COVERFLUX GR 2002 is added to the metal surface after melting is complete. The dross must be pushed out of the centre beforehand. COVERFLUX GR 2002 is plunged with a suitable plunging tool and stirred intensively into the melt in order to get an intimate contact between flux and melt thus a good cleaning action. Alternatively COVERFLUX GR 2002 is dosed into the pouring stream during the filling of transport ladles or crucibles. Drossing: If an FDU impeller treatment is being used COVERFLUX GR 2002 will react easily resulting in a light and dry dross. If no impeller treatment is taking place then the flux must be stirred vigorously with the dross on the melt surface using a preheated perforated ladle until a dry dross is achieved. After reaction is complete the dross should be carefully removed using an appropriate skimming tool. Crucible care: Always carefully clean any residues from crucible walls before refilling to get the best lifetime of crucibles.
