The molten aluminum melt is easily oxidized and aspirated. To this end, the selection of a low melting point, light specific gravity, good fluidity, and can quickly form a dense uniform protective film on the surface of the aluminum melt of the flux powder sprinkled on the liquid aluminum, after melting to form a liquid film, to prevent the suction and oxidation of the liquid aluminum, which is the basic requirements for the covering agent

• Shape: White powder (2.5kg/ bag)

• Melting point: < 660℃ Range of application: other aluminum and aluminum alloys except high magnesium alloys

• Recommended dosage: calculated and weighed according to the unit dosage of liquid aluminum area of 0.8 ~ 1.0kg/m2, and depending on the purity of the melt and the humidity in the air, it can be increased or decreased.

• Packing and storage: carton or woven bag, lined with plastic bag, 20kg or 25kg each.

Major advantage

Containing an appropriate amount of cryolite, with the effect of absorbing slag, especially when the liquid aluminum surface formed a liquid covering layer, and then add back charge, head and tail material or debris material, can melt part of the oxide in the slag, so that the liquid aluminum and the furnace gas separated, thereby reducing burning loss and oxidation suction.

Usage method

When the impurity and non-metallic inclusions are adsorbed by the covering agent, the shape of the molten slag on the surface is paste or liquid, and it is necessary to add the covering agent several times to ensure that the liquid surface is covered completely due to the amount of the covering agent added, it is best to add the covering agent when the metal begins to melt, and the covering agent should be sprinkled to protect the melt during the thermal insulation standing process after all the melting.
