Description
It is a powder flux used for Magnesium and
Calcium removal from molten aluminium alloys for secondary
aluminium alloys producers. Also it is removing
non-metallic inclusions (oxide layers, carbides and others)
and decreases gas content in aluminium melt. The
dry and powder-type dross with low metallic content
was obtained after addition of this flux.
Applications
Effective Magnesium and Calcium
removal from molten aluminium alloys, drossing off
and cleaning aluminium melt for aluminum scrap
recycling for secondary aluminium alloys preparation.
Aluminum melt surface covering. Can be used for all
types of melting furnaces. Reduction of Mg and Ca
content is often question for secondary aluminium
alloys producers. In past the chlorine gas was used.
Today, worldwide, the special fluxes are using because
of chlorine gas extremely dangerous.
Method of use
1. Add flux on melt surface.
2. Mixing the flux in melt by mechanical (electromagnetic)
stirring or by hand instruments.
3. Waiting up to 10 min for products of reaction
float on surface.
4. Dross removal and check Mg or Ca content. If it
is above the requirements repeat the flux addition.
5. Melt pouring.
The temperature of aluminium melt must be above
760°С.
Flux addition can be made through flux injection.
