1.Use in the furnace: According to the smelting and doping of aluminum alloy, the general dosage is 0.1-0.3% of the weight of the molten aluminum (that is, adding 1-3 kg of drossing flux per ton of molten aluminum).

2.Use outside the furnace: The aluminum slag removed from the furnace can be heated by a drossing flux or aluminum dross ash separator to achieve a good separation effect of the aluminum slag.

3.Application areas, market prospects and industrialized production conditions: It is mainly used for smelting pure aluminum, aluminum alloy and recycled aluminum, to remove the surface dross inside the molten aluminum, and to absorb the inclusions near the surface layer, and it can also be used for frying slag. It is one of the purification fluxes that must be used in the smelting of aluminum and aluminum alloys. The market demand is large and the application prospect is broad. The drossing flux widely use in factory production, but some small workshop also used in crucible in order to save cost, they use crucible to achieve the slag-aluminum separability. The production equipment and process of aluminum drossing flux are relatively simple, mainly drying furnace, crushing equipment, stirring and mixing equipment, and simple packaging equipment. The equipment investment is small, and the production process is easy to master.
