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。
ViewCast software was used to simulate the process of lost foam casting of turntable casting. The result of casting solidification process was obtained and the position of shrinkage and shrinkage defect was predicted. On this basis, the new technology scheme of turntable casting is confirmed. The results show that on the basis of a few changes of the original process plan, the original process plan can be optimized and the technical requirements can be met only by adding cold iron.
