摘　　要：在微机上用数值摸拟技术计算了灰铸铁件飞轮凝固过程中的温度场，分析其工艺方案中内浇口的凝固封闭时间，预测内浇口尺寸对铸件内部质量的影响，以便将该尺寸推广到其它灰铸铁件的工艺设计中。Temperature field of flying wheel casting during solidification process was calcu lated by means of the technique of computer simulation on microcomputer in this pa per. The solidification time of gates in the technology plan and the effects of size of gates on the inner quality of casting were all analyzed in this paper. The research re sults can be applied to the other technology design of gray iron castings.
