摘　　要：为预测熔铸AZS材料铸件中产生缩孔的位置和大小,分析浇注温度对铸件凝固的影响,以提高铸件质量,采用Pro Cast软件对熔铸AZS33的熔铸成型过程进行了数值模拟。模拟结果显示:缩孔易出现在浇冒系统与铸件连接处,通过改进浇冒口的形状和大小,选择四棱柱形浇冒系统可实现缩孔位置的上移;同时通过对比浇注温度对铸件凝固的影响,认为较为合适的浇注温度在1 810℃左右。The AZS33 fused casting process was simulated with ProCast software in order to predict the size and location of the shrinkage cavity formed during the casting and to analyze the effect of the casting tem- perature on the casting solidification to improve the quality of the casting, Simulation results show that the shrinkage cavity tends to appear in the jointing part of the gating riser system and the casting;improving the shape and size of gating riser and choosing quadrangular prism gating riser system can move the shrinkage casting location up;the suitable temperature is about 1 810℃.
