从感应炉加热的有关原理和电磁场、热场、流场等多物理场耦合计算的有限元方法着手,对感应加热电磁场、温度场以及熔体的运动情况进行理论推导,得到电磁场、温度场和流场分布的数学模型及相应的有限元分析模型。使用ANSYS Multiphysics等模拟软件得到坩埚内电磁场、电磁力、温度场以及熔体运动的分布。将数值模拟的结果与实验结果相对比,证明了数值模拟的结果达到了工艺上的准确性,并且对实验具有指导作用。
Based on the principle of induction furnace heating and the finite element method of multiphysics coupling calculation, such as electromagnetic field, thermal field and flow field, the electromagnetic field, temperature field and the movement of the melt are theoretically deduced, and the electromagnetic field, temperature field and Mathematical model of flow field distribution and corresponding finite element analysis model. Using ANSYS Multiphysics and other simulation software to get the crucible electromagnetic field, electromagnetic force, temperature field and the distribution of melt movement. The numerical simulation results compared with the experimental results show that the numerical simulation results reached the technical accuracy, and the guidance of the experiment.
