摘要
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ProCAST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.
Abstract
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.
