摘要
对麦克斯威方程组和导热微分方程进行分解化简 ,得到计算无限长轴对称工件的电磁场、感生涡流和温度场分布的基本方程。基于这些方程在ANSYS软件上实现了对厚壁筒形工件连续感应热处理的计算机模拟计算。计算了加热、淬火和回火等热处理过程中 ,工件温度变化和加热功率变化 ,预测工件淬火冷却时的组织转变 ,计算中考虑了工件材料物理参数随温度变化对加热过程的影响。通过模拟计算 ,实现了对连续感应热处理工艺的优化分析 。
A mathematical model has been developed to describe the electromagnetic,eddy current and temperature fields in axisymmetric workpieces.Based on these equations, continuous induction heat treatment of the thick wall tube,including heating, quenching and tempering,is simulated by finite element method on ANSYS software.The time temperature diagrams are drawn.Calculations take into account the temperature dependence of material characteristics.The heating power is calculated and the microstructure transformation during quenching is predicted.The results show that the computer simulation by finite element method could be applied to the optimal design of process parameters in continuous induction heat treatment.
