Abstract: A process for heat treating a steel bar to produce a grinding rod having a softer core of at least 99% pearlite and having a hardness of less than 45 Rockwell C, an outer shell of martensite having a hardness of at least 50 Rockwell C and softer end portions having a ...
More2017-10-2 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 ...
More2016-9-27 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 ...
MoreGrinding 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.
