中文摘要：利用ViewCast软件对转盘类铸件消失模铸造过程进行了计算机模拟,获得了铸件凝固过程结果，预测了可能产生缩孔、缩松缺陷的位置。在此基础上确定了转盘类铸件的新工艺方案。结果显示，在少许改变原工艺方案的基础上，仅通过增加冷铁，就可对原工艺方案进行优化，并满足其技术要求。
英文摘要：The solidification process of EPC bus rotor was simulated by ViewCast software, and the solidification process were obtained, the location of shrinkage defects was forecasted. Based on this, the new casting process was designed and simulated. The results show that only adding chills for process optimization, the original casting process is modified, and the casting technical requirement is met.
