中文摘要：运用ProCAST铸造仿真软件对离心铸造盘状零件充型和凝固过程进行数值模拟，研究了铸件可能产生的缺陷及位置，分析了缺陷产生的原因并优化铸造工艺。通过减少内浇口的数量，提高模具温度，减少热量散失，可以形成盘状零件的顺序凝固，有利于铸件质量的提高。试验表明，模拟结果与试验结果相吻合。
英文摘要：Using ProCAST casting software to simulate the filling and solidification process of centrifugal casting discoid part, the casting defects and its positions in the process were predicted. On the basis of this, the reasons for the defects were analyzed, and the casting process was optimized. Through reducing the number of ingates, increasing the die's temperature, reducing the heat loss, the progressive solidification of the castings could be realized, the casting quality could be improved. Comparing experimental results with simulation results show that they are coincident.
