摘要

基于铸造数值模拟技术

对高压开关用铝合金铸件的凝固过程和充型过程进行了模拟。通过对凝固过程的温度场和铸造缺陷进行分析

并依据分析结果对工艺进行了改进

最后设计出合理的铸造工艺。结果表明

对于铝合金壳体类铸件

在其圆周局部厚大部位可采取砂芯中增加补缩通道方法

实现铸件顺序凝固

较好解决了缩孔、缩松问题。

Abstract

Based on CAE

solidification and filling process of aluminum alloy high-voltage switch housing were simulated.Through the analysis of temperature field and casting defects in the aluminum alloy housing during the solidification process

process was optimized.The results show that the aluminum metal alloy housing can eliminate the shrinkage porosity（holes）through adding feeding channel in the sand core for partial thick-wall position to realize the sequential solidification.
