| 摘 要： | 用高速钢制作矿用牙轮钻头轴承系统的衬套，普遍存在破裂现象，通过采用低温淬火和优化工艺参数，其韧性大幅度提高，工业试验的破裂率由传统的90％－96％下降到7％－13％，钻头穿孔米道提高了17％。

| Abstract: | Fractures occurr frequently in the bushing made from high speed tool steel on the bearing system of blast hole rock bits A big increase in toughness is obtained through low temperature quenching and parameter optimization The industrial test shows that the fracture rate declines from 90%~96% by 7%~13% and drilling meters increase by 17%. |
