摘　　要：介绍了轴承钢管制套圈加工过程中常见缺陷的特征、产生原因及分析手段,通过2个轴承钢管制套圈缺陷的分析案例对套圈在加工过程中所产生缺陷的分析思路和方法进行了总结,即借助金相检验、扫描电镜与能谱分析等手段,获取缺陷的形貌特征和微观金相组织等,进而分析缺陷产生的原因并提出相应改进措施。The characteristics,causes and analysis methods of common defects are introduced during processing of rings made of bearing steel tubes.Through two analysis cases of defects in rings made of bearing steel tubes,the analysis ideas and methods for defects generated during processing of rings are summarized,that is,by means of metallographic inspection,scanning electron microscopy and energy spectrum analysis,the morphology characteristics and microstructure of defects are obtained,and then the causes of defects are analyzed and corresponding improvement measures are proposed.
