基于ProCAST的异型舱体低压铸造工艺优化

Process Optimization of Low Pressure Casting Heterotypic Cabin Based on ProCAST

针对某型号异型舱体铸件的结构特点和铸造难点,设计了低压浇注工艺方案,使用Pro CAST软件对铸件充型以及凝固过程进行模拟。对缩松、缩孔缺陷进行了原因分析,经工艺优化,通过增加U型部位和Y型支架部位冷铁厚度,避免了缩松、缩孔缺陷的产生,实现了舱体的铸造成形,使舱体达到了I类铸件要求。

Aimed at the structural characteristics and casting difficulties,the low pressure casting process of hetero⁃typic cabin was designed.ProCAST software was applied to simulate the filling and solidification field,and origination of shrinkage porosities(holes)was analyzed.After processing optimization,the defects are avoided by adding the thick⁃ness of the cold iron in U and Y parts,achieving the formation of cabin,which meet the standards of Class I cast.
