铸件磁粉探伤检出率的影响因素分析

摘要

Magnetic particle inspection is one of the effective methods for detecting surface defects of castings. How to improve the detection rate of surface defects is a long-term exploration in the field of magnetic particle testing, but also the main objective of the practical work. Through the long-term practical experience of the accumulation, and the experimental analysis of many kinds of influence variables, the factors that affect the detection rate of magnetic particle inspection have been summarized, it can be referred to for industry insiders.%对于检测铸件表面缺陷，磁粉探伤是一种有效的检测方法。如何提高表面缺陷检出率是铸件磁粉探伤领域长期探索的问题，也是实践工作中积极改进的主要目标。通过长期实际工作经验的积累，并对多种影响变量进行实验分析，总结出一些常规的影响磁粉探伤检出率的因素，以供业内人士参考。
