对机器的铸铁导轨采用电接触表面淬火工艺,由于它设置简单,使用方便,效果显著同时有淬火后导轨变形量小。能保持原来精度的特点,已得到广泛应用。但如何掌握好这一工艺方法仍是一个带普遍性的问题。下面根据我们多年来的使用情况,谈谈我们的一些体会。一、淬火质量与工艺参数确定我们应用如臬第二电器厂生产的JDC-1,JDC-2型电阻淬火装置对导轨表面淬火,经过试验得出如下最佳工艺参数:(1)淬火电流
Cast iron rail on the machine using electrical contact surface hardening process, because it is simple to set up, easy to use, the effect is significant at the same time after quenching rail deformation is small. To maintain the original accuracy of the features, has been widely used. However, how to master this process is still a common problem. Here are some of our experiences based on our usage over the years. First, quenching the quality and process parameters to determine Our application such as the second electric plant production JDC-1, JDC-2-type resistance quenching device on the rail surface quenching, after the experiment obtained the following optimal process parameters: (1) quenching current
