摘要

基于ProCAST软件对高纯铝的定向凝固过程进行数值模拟研究

通过自建的模型成功模拟了高纯铝的定向凝固过程。结果发现

在凝固过程中特殊的流场和温度场会导致铸锭中段形成反常的溶质富集区

实际生产中应当在凝固中期适当加强搅拌消除。

Abstract

A numerical simulation on the directional solidification process of high purity aluminum was conducted by finite element simulation software ProCAST. The directional solidification was successfully simulated by self-built model. The result reveal that during the solidification process

the special flow field and temperature field lead to the formation of the abnormal solute enrichment zone in the ingot

which should be eliminated through appropriate stirring in the middle of solidification during the actual production.
