Graphite molds should be produced and processed by cutting methods to improve the smoothness of the graphite mold surface and reduce the degree of adhesion between the molten metal and high-purity graphite. The composition of the carcass powder is one of the factors that cause the metal plastic film to stick to the high-purity graphite. Because iron is a strong carburizing agent, if the carcass is iron-based, there will be obvious reaction and melting between the carcass and the abrasive tool, causing the carcass melt to stick to the high-purity graphite and destroying the graphite mold. It is suggested that when calcining the iron-based carcass, a strong release agent should be brushed on the surface of the blade and the abrasive tool to reduce the adhesion of the abrasive tool during mold unloading, reduce the degree of damage, and increase the service life of the abrasive tool.2. The fracturing damage of the grinding tool is also related to the resistance of the graphite materia
