摘　　要：42CrMo4风电主轴采用常规热处理工艺后,低温冲击韧性不能满足要求。采用改进的降温淬火工艺,将淬火温度从860℃降至810℃,以及水淬油冷方式使产品完全满足技术要求。Mter adopting the normal heat treatment process for 42CrMo4 wind power main shaft, the low temperature impact toughness can not satisfy the requirements. This problem can be solved by means of adopting the improved cooling and quenching process. Decreasing the quenching temperature from 860 ℃ to 810 ℃ and using water quenching and oil cooling method can completely satisfy the technical requirement for products.
