摘要

基于ProCAST软件的数值模拟

分析了ZL101A合金熔模铸造零件缺陷出现的原因。通过模拟分析发现

零件凸台处的厚度不均匀是产生缩松、缩孔缺陷的原因。对于厚度不均匀的零件

提高型壳温度

同时选择合理的浇注温度

可以有效消除此类零件的内部缺陷。试验表明

当浇注温度为720℃

型壳预热温度为400℃时

可以较好地避免缩松、缩孔缺陷的产生

获得较为合格的铸件。

Abstract

Origination of defects in investment casting aluminum alloy parts based on ProCAST was analyzed.The simulated results reveal that the uneven thickness of the part flange is mainly responsible for the shrinkage porosity（hole）.The shrinkage porosities（holes）can be eliminated through increasing temperature of the mold shell and choosing a reasonable pouring temperature

The experiment indicates that acceptable castings without shrinkage porosities（holes）can be manufactured with pouring at 720℃and mold shell preheat temperature of 400 ℃.
