| 摘 要： | 采用有限元分析法和ANSYS软件,引入复矢量磁位,推导了感应加热有限元模拟的数学模型.讨论了感应加热有限元分析中温度场与电磁场耦合、工件材料物理参数的温度依赖性等关键技术问题的处理方法.分析了电渣炉夹具的感应加热过程,得到了夹具的温度分布状况以及温度随时间的变化规律.结果表明:温度的最大值主要集中在夹具的表层,且心部几乎未加热,其数值模拟结果与工程实际应用工况基本一致.

| Abstract: | A mathematical model was developed introducing the dual-vector magnetic potential into it for simulation of induction heating,based on FEM and the software ANSYS. Discusses the key technological problems and the ways to solve them,such as the coupling of temperature field with electromagnetic field in FEA and the dependence of physical parameters of workpiece materials on temperature. The induction heating process of the chucking for electro-slag furnace was analyzed to find out the temperature distribution... |
