[0002] Sand casting is a production method in which molten metal is poured into the cavity of a casting mold and cooled and solidified to obtain a product. Sand molds are usually used to manufacture cast iron parts. The raw material of the sand mold is mainly sand, which is mixed with a binder, water, etc. The sand mold material must have a certain bonding strength so that it can be shaped into the required shape and resist the erosion of high-temperature molten iron without collapsing. When making a sand mold, it is necessary to consider where the molten iron flows in and how to fill the cavity to obtain high-quality castings. After the sand mold is made, it can be poured, that is, the molten iron is poured into the cavity of the sand mold. During pouring, the temperature of the molten iron is 1250-1350 degrees, and the temperature is even higher during melting. Then, it also needs to go through processes such as sand removal, repair, and grinding before it can become a qualified casting.
