[0002] In the process of aluminum alloy casting, the aluminum ingot is first placed in a gas furnace, and the aluminum ingot is heated and melted by the heating of the gas furnace. However, due to multiple factors such as impurities in the aluminum ingot raw material, oxidation reaction, process waste burning loss, improper melting operation, and intermetallic compound generation, there are a lot of residues on the surface of the molten aluminum liquid, and the residues are composed of slag and dross.
