摘要

利用数值模拟软件ProCAST对K423合金衬板铸件的铸造工艺方案进行了数值模拟

模拟确定了铸件缩松、缩孔缺陷的分布及产生原因。根据模拟结果改进了铸造工艺。经小批量试制发现

采用改进工艺生产的铸件在X射线检测中无明显缺陷

致密度达到99.8%。

Abstract

The numerical simulation software ProCAST was used to simulate the initial casting process of the K423 alloy liner castings. The distribution and causes of shrinkage porosities in the castings were determined by porosity criterion and temperature field analysis. The casting process design was improved based on the simulated results. Through small batch production

it is found that the castings produced by the improved process has the obsence of defects under X-ray detection and the relative density reaches 99.8%.
