摘要: 采用有限元方法对40CrNi2MoA钢大型圆弧导轨的表面感应淬火和回火过程进行了模拟研究,分析了导轨表面硬度、淬硬层深度、整体变形量和残余应力的变化,并与根据导轨实际热处理测试结果进行了对比分析。结果表明,导轨感应淬火和回火后的表面硬度、淬硬层深度、整体变形量的模拟结果与实际热处理结果基本一致,模拟结果较为准确,可用于导轨热处理结果的预测与工艺参数的优化。

Abstract: Simulation of surface induction quenching and tempering process of 40CrNi2MoA steel large arc guide rail was carried out by using finite element method. The surface hardness, hardened layer depth, overall deformation and residual stress of the guide rail were analyzed and compared with the actual heat treatment test results. The results show that the simulation results of surface hardness, hardened layer depth and overall deformation of the guide rail after induction quenching and tempering are basically consistent with the actual heat treatment results, which indicating that the simulation results are comparatively accurate and can be used to predict the heat treatment results of the guide rail and optimize the process parameters.
