摘要
从电磁场的基本原理出发,利用ANSYS有限元软件建立铝硅合金半固态电磁铸造的磁流耦合场模型,通过数值模拟计算磁场对流场和温度场的影响。结果表明,电磁场频率直接决定流场及温度场的分布,高频电磁场感应加热效果明显、洛伦兹力主要表现为电磁压力,有利于电磁铸造约束成型。
Based on classical electromagnetic theory, the coupled simulation model of electric field, magnetic field and flow field of semi-solid Al-Si alloy have been established by ANSYS finite element software.The influences of magnetic field on flow field and temperature field have been studied by numerical simulation.The results indicated that electromagnetic field frequency determined the distribution of flow field and temperature field.High frequency electromagnetic field had remarkable effect on induction heating.The Lorentz force characterized in the form of electromagnetic pressure and was beneficial to electromagnetic casting.
