The heat treatment of Forged Grinding Ball is the process of heat, keep warm, then cool down, cooled at different speeds. It can not be interrupted in this process. Heat treatment process is also one of the important factors to ensure the quality of Grinding Balls.
Wear resistant steel grinding ball heat treatment is better to improve the hardness and wear resistance. Greatly increase the service life. After heat treatment, the internal structure of the steel ball changes. We divide the heat treatment process into three kinds: whole heat treatment, surface heat treatment, chemical heat treatment. According to the different heating medium, heating temperature and cooling method, each big class can be divided into several different heat treatment processes. The same kind of grinding balls with different heat treatment process can obtain different tissues, thus having different properties.
