中文摘要：以大型铸钢件为例，利用View Cast软件进行铸造工艺设计。首先根据裸件的凝固结果和热节数量、位置计算出冒口尺寸和数目，然后对铸件及其冒口进行凝固计算，根据计算结果优化得出最佳的补缩系统。之后进行浇注系统的设计计算，并对铸件的充型凝固过程进行计算。计算结果表明，该铸造工艺能平稳地充型，补缩系统能有效补缩凝固过程中所需要的金属。
英文摘要：Taking a large cast casting steel as example, View Cast software was introduced to design the casting process. After the dimensions and numbers of risers were determined based on the solidification results and the number of hot spots, the optimal feeding system was obtained. Finally, the gating system was designed, and the filling process and solidification process were simulated. the results show that the casting process can smoothly fill and the feeding system can feed the casting effectively.
