Heat treatment furnace cast fan is a kind of equipment used in heat treatment process. It is mainly used for heating and cooling metal materials to change their material properties and organizational structure. The cast fan of heat treatment furnace usually consists of furnace body, heating system, cooling system and control system. The working principle of the heat treatment furnace cast fan is to heat the metal material to a certain temperature, then keep it warm for a period of time to change its internal organizational structure, and finally cool it quickly through cooling, thereby improving the material properties. Heat treatment furnace casting fans are mainly used in the casting industry to perform heat treatment processes such as annealing, normalizing, and quenching on castings. It can improve the hardness, strength, wear resistance and corrosion resistance of castings, improve the organizational structure of castings, reduce internal defects, and improve the quality and ser…
