本文介绍采用霍尔传感器测试铸件的剩磁来确定铸件中珠光体的含量。它改变了用传统的金相解剖方法来分析和检验曲轴的性能指标。计算机处理使得测试过程大为缩短,保证产品质量又提高了经济效益
This article describes the use of Hall sensors to test the remanence of the castings to determine the amount of pearlite in the castings. It changed the traditional metallographic dissection method to analyze and test the performance of the crankshaft. Computer processing makes the test process is greatly reduced, to ensure product quality and increase economic efficiency
