为进一步深入研究电磁铸造技术,对液态金属液的速度场进行了理论分析,并应用ANSYS软件完成了数值模拟,对速度场实现了有限元建模,以及力矢量图、速度矢量的有限元分析。结果表明,金属熔体经过一短暂的启动时间,金属熔体的速度和受力才会随时间的增大而增大,最后趋于平稳;熔体中某些地方产生了凝滞;电磁铸造可以忽略温度变化对熔体速度的影响。电磁凝固使得铸件的晶粒细化,晶粒尺寸均匀。
In order to further study the electromagnetic casting technology, the velocity field of liquid metal liquid is theoretically analyzed. The numerical simulation is completed by ANSYS software. The finite element modeling of the velocity field, finite element analysis of force vector and velocity vector . The results show that after a brief start-up time of the metal melt, the speed and force of the metal melt increase with time and finally become stable; the melt stagnates in some places; the electromagnetic casting can Ignore the effect of temperature changes on melt speed. Electromagnetic solidification makes the casting grain refinement, grain size uniformity.
