摘　　要：针对某企业生产的17Cr MnBHZ钢行星架在车削过程刀具磨损严重、机床抖动等问题,通过9组正交实验,研究了17Cr MnBHZ钢行星架调质热处理工艺,分析了不同的工艺参数(淬火冷却介质、冷却保持时间、回火温度、回火保持时间)对零件调质后的抗拉强度及硬度的影响,得到了较为优化的工艺数据,对指导生产发挥了重要的作用。Aiming at serious tool wear and machine tool jitter in cutt process of 17 CrMnBHZ steel planetary carrier produced by an enterprise, the quenching and tempering heat treatment process of 17 CrMnBHZ steel planetary carrier were studied by 9 groups orthogonal experiments. The effects of different process parameters(quenching cooling coolant, cooling retention time, tempering temperature, tempering retention time) on the tensile strength and hardness of the parts after quenching and tempering were analyzed. The optimized process data are obtained, which can play an important role in guiding production.
