After balls separating and cleaning, grinding balls need to heat treatment. However, the different percentage of chrome, heat treatment process is not the same. Types of Heat Treatment Process. For high chrome balls, Cr is over 10%, need quenching first and then tempering. For low chrome balls, Cr bellow 10%, only big size of balls need to be tempered. (Detailed process according to clients ...

Following standard heat treatment, steel grinding balls possess hardness values greater than 60 Rockwell C in the case of 3 inch diameter balls. The internal zone is also hard and therefore has low toughness, reducing the working life of the ball. The objective of the present study was to improve the quality of 3 inch diameter grinding balls by producing higher surface hardness and a central ...
The term grinding burn while grinding is understood as the thermal damage of a ground part caused by an incorrect grinding process. Grinding burn is caused by excessive heat dissipation into the part material. As materials cool as rapidly as they heat, the material undergoes a treatment similar to a tempering process. At high enough tensile stresses, caused by the grinding burn at the outer ...
