In the production process of forged steel balls, heat treatment is a key link, which is directly related to the wear resistance and service life of the balls, through a stable heat treatment process to achieve the hardness range demanded by customers, while increasing the hardened layer of the balls, which is beneficial to the milling use of wear resistance. In addition, the heating methods of forged steel balls include coal reflector heating, gas heating furnace (natural gas, gas, heavy oil, etc.) and electric furnace heating methods, each with its own advantages and disadvantages, and the selection of the appropriate heating method is essential to ensure the quality of steel balls.
