摘　　要：采用ProCAST软件对某铝合金壳体熔模铸造工艺设计进行了优化,预测出原方案造成的铸件疏松问题并改进了工艺。采用优化前后工艺方案试制了壳体铸件,无损检测结果表明,原工艺方案造成的试样件缺陷位置与数值模拟结果相符,采用优化后工艺方案试制的样件无缺陷,符合产品质量要求。The investment casting process design of an aluminum alloy shell was optimized by using ProCAST software,and the casting shrinkage porosity caused by the original scheme was predicted and the process was improved.The shell casting was trial produced by using the optimized and pre optimized process plan.The nondestructive testing results showed that the defect positions of the sample pieces caused by the original process plan were consistent with the numerical simulation results.The sample pieces produced by the optimized process plan had no defects and met the product quality requirements.
