摘要
对产生中心孔洞的20CrMnTi钢凸轮轴毛坯进行了剖面分析,从工艺因素、低倍组织、金相检验等方面进行系统研究,找出了该毛坯产生中心孔洞的主要原因并提出了改进建议。
The section analysis is done to cam shaft blank of 20CrMnTi in which there areinner hole. The systematic study is engaged from process, low times microstructure and metallographic examination, the main reason for the holes found out, some improving suggestions proposed.
