摘　　要：分析了影响铁素体可锻铸铁电磁检测中稳定性和再现性的因素，探讨了利用最大磁导率μｍ进行对比的检测方法及电源稳定度的重要性。结果表明，这种检测方法稳定可靠。The influence factors of stability and repeatability for electromagnetic measuring of malleable iron are analyzed.The method of mutual comparison inspection has been explored by using m of the material.It is found that the steadiness of the power is most important.The results show that this method is stable,reliable and repeatable.
