[0002] Zinc-aluminum-magnesium alloy is an alloy composed of three elements: zinc, aluminum and magnesium. It has good strength, corrosion resistance and thermal stability. It is widely used in aerospace, automotive industry, electronic equipment and other fields. In the production and processing of zinc-aluminum-magnesium alloy, melting and casting equipment is required to melt and cast the raw materials.

[0003] The Chinese utility model patent with announcement number CN215952201U discloses a smelting and casting device for producing zinc-aluminum-magnesium alloy. The device includes a melting furnace, a swinging chute, multiple molds arranged in a semicircle below the casting end of the swinging chute, and a mold protection cover arranged on the outside of each mold. The lower end of the melting furnace is provided with a casting hydraulic drive mechanism, an argon ventilation pipe extends into the melting furnace, and the argon ventilation pipe is evenly distributed with a number of ventilation holes. The swinging chute is provided with a carbon dioxide gas protection mechanism. The inner wall of the mold protection cover is provided with an annular carbon dioxide gas distribution pipe above the mold, and the carbon dioxide gas distribution pipe is evenly distributed with multiple exhaust holes. Two air inlet pipes are connected to the left and right ends of the carbon dioxide gas distribution pipe.
