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。 ProCAST casting simulation software was used to simulate the filling and solidification process of the disc-shaped parts. The possible defects and positions of the castings were investigated. The causes of the defects were analyzed and the casting process was optimized. By reducing the number of gates, increasing the mold temperature, reducing heat loss, the formation of disk-shaped parts of the order of solidification is conducive to improving the quality of castings. Experiments show that the simulation results are consistent with the experimental results.
