Effect of Heat Treatment on the Hardness and Wear of ...

2017-10-2  It may be seen that after heat treatment the hardness of experimental balls is the same as for balls from other producers, i.e., heat treatment regimes were similarly correct. Ball weight loss is given in Fig. 4 after grinding rock for up to 135 min. It is seen that wear resistance for balls in the cast condition is quite good and improves ...

Proposed heat treatment conditions to improve

2016-9-27  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 ...

Residual Stress, Heat Treatment, Grinding Burn Test ...

Grinding Burn Detection. Grinding thermal damages, also known as grinding burns, will shorten the fatigue life of critical, dynamically loaded components and can lead to severe failures. Grinding burns occur when the energy from grinding produces too much heat. Grinding burn decreases hardness and causes tensile residual stress.
