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.
1. It will remove excessive magnesium content in aluminium alloy effectively.
2. It has relatively excellent refining result.
The use method is the same as with that of refining flux.
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.
