摘要
15A钢销轴在网带炉进行气体氰化淬火、低温回火。以往的氰化温度高,氨气流量大,经常出现硬度不足等问题,且发生过工件在装配中脆断。本文对出现的问题进行了分析,提出了改进工艺的方法,装配性能表现良好。
The gas cyaniding quenching and low temperature tempering for 15A steel pin shaft were carried out in the net belt furnace. In the past, there are many problems, such as high cyaniding temperature, large ammonia flow, insufficient hardness, and the workpiece occured brittle fracture in the assembly. In this article, the problems has been analyzed and put forward the method improved process to get the good assembly performance.
