The solidification simulation for HSi80-3 silicon brass rudder bonnet by the Procast software has been conducted based on two kinds of gating systems to investigate the potential shrinkage hole (porosity) position in the castings.

• 运用Procast软件对HSi80-3硅黄铜船用舵盖零件在两种浇注工艺方案下的凝固过程进行模拟计算,在此基础上分析探讨了该铸件可能产生缩孔或缩松的部位。
