Principle:
By use of powder spraying machine, spray de-magnesium flux into aluminium melt bath with high purity nitrogen. The sprayed de-magnesium flux powder will react with magnesium in alloy chemically to float the reactant on the surface of aluminium liquid so as to realize magnesium removal.
Main features:
1. It will remove excessive magnesium content in aluminium alloy effectively.
2. It has relatively excellent refining result.
Use method;
The use method is the same as with that of refining flux.
Technical parameters:
1. Temperature for charging: 710o C-740o C.
2. Time: 10-15 minutes (6-20 ton furnace)
3. Nitrogen pressure: 1.2
4. Use level: De-magnesium flux shall be added at 4-6: 1 According to de-magnesium quantity.
Packaging and storage:
It is
