磁弹仪检查高温轴承钢套圈磨削烧伤的规范和评价标准

Standard and evaluation criterion to test grinding burn of high-temperature bearing steel ring in magneto-elastic apparatus

在介绍磁弹仪的工作原理和信号判别方法的基础上,通过对磁弹仪检测高温轴承钢套圈磨削烧伤试验数据的分析,并用酸洗法和金相法加以验证,制定了磁弹仪检测的规范和评价标准。

On the basis of introducing the working principle of magneto-elastic apparatus and signal discrimination, through the analysis of the test data from detecting grinding burn of high temperature bearing steel ring by magneto-elastic apparatus,and verifying by the acid washing and metallographic analysis so as to formulate the magneto-elastic apparatus test speciifcations and evaluation criterion.
