[0002] Casting is a metal heat processing technology that humans mastered relatively early. It is a method of pouring liquid metal into a casting cavity that is adapted to the shape of the part, and then cooling and solidifying it to obtain a part or blank. The material of the mold is usually sand, metal or even ceramic. Generally speaking, the used casting sand cannot be reused due to sticking and sintering, which leads to the need for foundry companies to purchase a large amount of casting sand, thereby increasing material consumption and causing high production costs. Therefore, it is necessary to recycle and reuse the casting sand.
