摘要
金属磁记忆检测是无损检测领域的一项新技术,不仅可以对铸钢构件的失效进行早期诊断,而且可以对铸钢件缺陷进行准确检测。本文研究了磁记忆技术在铸钢车钩检测中的实际应用,结果表明对于钩体、钩舌、钩体框的检测磁记忆技术是可行的。
Metal Magnetic Memory Testing(MMMT) is a new technology in metal non-destructive test(NDT). MMMT is not only used for diagnosis at the early stage of failure, but also for accurate defect inspection of steel casting. The practical application of MMMT in the inspection of cast steel coupler is investigated and the result shows the technique is feasible in the inspection of coupler body, coupler knuckle and coupler yoke.
