Some factors influencing the wear characteristics of grinding cast steel ball |
| Abstract |
In order to investigate the favorable condition of thermal treating and mass effect during the solidification and thermal treatment of grinding cast steel ball containing 1.61%C, 16.5%Cr, 0.50%Mo & 0.23%V, hardness and microstructure have been tested, and wear test was also performed. On the basis of this experiment, results were summerized as follows. 1) The thermal treated structure of grinding ball is related to mass effect during the solidification. 2) 60㎜ and 70㎜ ball are greatly influenced by mass effect. 3) The optimum temperature for austenitizing is 1050℃-1100℃ |
