摘　　要：采用三维建模软件UG和铸造模拟软件ProCAST对叶轮消失模铸造过程进行数值模拟,分析了浇注温度对铸件有效应力的影响。结果表明,浇注温度为1 400℃时,叶轮铸件的内应力处于较低水平。对模具关键部位进行"激冷",可以减少叶轮铸件的缺陷发生率,提高产品质量。Simulated analysis on lost foam casting defects of impeller by ProCAST software, and the effect of pouring temperature on effective stress were studied. The results show that the lowest stress appears when the pouting temperature is 1 400 ℃. Adding cold iron in the key parts of the die can reduce the possibility of defects and improve the quality of castings.
