摘　　要：快速断电技术是为了解决轴类零件在直流纵向磁化过程中两端面不能有效磁化的问题而提出来的,它旨在纵向磁化检测轴向圆周面缺陷的同时检测端面缺陷,从而省去单独检测端面缺陷的工序。多年来,该技术经过一步一步完善,似乎解决了一些零件端面不能磁化的问题,但实际上,轴类零件直流纵向磁化时磁化两端面并显示出缺陷的现象,并不是在断电瞬间产生的,而是在磁化过程中产生的。本文收集了多年来在快速断电特性方面的研究和应用资料,并从理论和实验上探讨轴类零件直流纵向磁化时两端面缺陷显示的真正原因。The original motivation of quick break is proposed to solve the problem that the end faces of shaft parts can't be effectively magnetized during the DC Longitudinal Magnetization process.It aims to detect the defects of the axial circumferent surface by longitudinal magnetization and at the same time detect the defects of the end face,so as to eliminate the process of detecting the defects of the end face alone.Over the years,the technology has been perfected step by step,it seems to solve the problem that some parts end faces can not be magnetized,but in fact,the defect indication of shaft parts'end faces is generated during the magnetization process,rather than at the moment of quick break.In this paper,many years of research and application data in the field of quick break are collected,the real cause of defects on the end faces of shaft parts in DC Longitudinal Magnetization is discussed theoretically and experimentally.
