| Abstract: | Using the authors developed numerical simulation software of temperature field,the solidification process of wear resisting cast balls was numerically simulated. Based on the simulation and the law of temperature distribution of solidification process for the cast ball,the shrink holes of the cast balls were removed by adjusting the foundry parameters. Therefore fatigue impact test shows that the diameter 127?mm cast ball can be fallen more than 8?000 times before fragmentation. |
