It is a powder flux used for removing nonmetallic
inclusions (oxide layers, carbides and others),
drossing off and covering surface in aluminium melt.
The dry and powder-type dross with low metallic content
was obtained after cleaning operation by this flux. The
dross does not stick on furnace lining and crucible
Drossing off aluminium melt for aluminum
scrap recycling under melting procedure. Cleaning
foundry aluminium alloys (Al-Si) for wide range of
casting techniques (high pressure die casting, low pressure
die casting, gravity casting in permanent and sand
molds, others) and different furnace types.
Method of use
1. In case of aluminium scrap recycling Covering-
Refining flux introduces in melt stepwise with
every part of batch addition. The finish treatment
is doing before melt pouring.
2. In case of aluminium foundry alloys cleaning
for casting Covering-Refining flux introduces in
melt by hand foundry plunger under melt surface.
For all applications the temperature of treatment must
be above 720°С
