摘要

采用ANSYS有限元法对低频电磁铸造铝合金过程进行了数值模拟

分析了频率为15HZ

电流为150A

匝数为80匝时

铸锭边部及内部的磁感应强度分布

并在此条件下进行试验研究。试验结果表明

低频电磁铸造铝合金铸锭表面光洁

消除了铸锭表面的冷隔和表面偏析瘤

内部晶粒细小且为近球形

同时分析了质量改进的原因。

Abstract

The simulation of aluminum alloy in low frequency electromagnetic casting was performed by the ANSYS finite element method.In case of the frequency 15 Hz

current 150 A

coils 80

the magnetic flux intensity distribution in inter and outer of the ingot was analyzed

where the experiment was conducted also.The results show that the surface of the ingot is smooth

and its grain size is fine and globular

eliminating surface cold shut and exudations.The reason for the improved quality of the ingot is discussed.
