摘要
针对35钢托圈锻件出现硬度不合格的问题进行了分析,讨论生产工艺过程对硬度及其均匀性的影响,通过相应的改进措施,锻件硬度值完全满足用户要求,并且硬度均匀性控制在22HBW以内。
The issue of unqualified hardness of 35 steel backing ring forgings has been analyzed. Meanwhile,the influence of production process on hardness and hardness uniformity has been discussed. By means of relevant improvement measures,the hardness of forgings meets the requirements of customer completely. In addition,the uniformity of hardness is controlled within 22 HBW.
