摘要

提出了坩埚半径的设计思路

研究了坩埚半径对电磁搅拌制备半固态A356铝合金浆料时磁感应强度和电磁力分布的影响。通过ANSYS 15.0模拟了不同坩埚半径中半固态A356铝合金浆料受到的磁感应强度和电磁力沿坩埚径向的变化趋势。模拟结果表明

磁感应强度从坩埚中心沿坩埚径向0.85倍距离左右逐渐增大;电磁力整体上随坩埚半径的增大而增大

且增加的幅度越来越大

电磁力从坩埚中心到坩埚径向上0.9倍距离左右逐渐增大

而在边缘处急剧减小。对不同坩埚半径的试验结果进行对比

发现最佳的坩埚半径为30mm。

Abstract

The design idea of crucible radius was proposed

and influence of crucible radius on the magnetic flux density and electromagnetic force distribution of semisolid A356 aluminum alloy slurry was investigated.The change of magnetic flux density and electromagnetic force along the radius of the crucible for semisolid A356 aluminum alloy was simualted by ANSYS 15.0.The simulated results show that the magnetic flux intensity is increased from the center to the distance about 0.85 times of the crucible radius

decreased sharply and then increased near the edge.The electromagnetic force is increased with the increase of the crucible radius

and the increment-amplitude is larger and larger.The electromagnetic force is increased from the center to the distance about 0.9times of the crucible radius

decreased sharply at the edge.The experimental results of different crucible radius were compared with the simulated ones.The results reveal that the optimum crucible radius is 30 mm in the preparation of high quality semisolid aluminum alloy slurry.
