摘　　要：GIS铝合金支持缸铸件设计采用直浇道充型的站立式金属型低压铸造工艺,无横浇道,工艺出品率高,并采用AnyCasting铸造模拟软件仿真分析辅助工艺优化。仿真结果表明,初步设计工艺法兰附近凸起及法兰与加强筋相交位置存在铸造缺陷,筒口端没有缺陷。对一半凸起采取风冷铜镶块,不影响补缩的情况下,抑制热节,消除了该处缺陷。将暗冒口变更为环形暗冒口,补缩距离变小,法兰缺陷明显减小;进一步对环形暗冒口增加砂套,冒口凝固时间延长23 s,缺陷消除。The vertical metal mold low pressure casting process with sprue filling was designed for GIS aluminum alloy support vat castings,and the yield rate was high without runner.AnyCasting casting simulation software was used to simulate and analyze the auxiliary process optimization.The simulation results indicated that there were casting defects at the protrusion near the flange and the intersections of the flange and reinforcing ribs,and there was no defect at the end of the sleeve.Wind cooling the copper inlay block was applied to half of the protrusion to suppress hot spot without affecting filling and eliminate defect in that area.The blind riser was changed to the annular blind riser,the feeding distance became smaller,and the flange defect was obviously reduced.Furthermore,a sand sleeve was added to the annular blind riser,and the riser solidification time was extended by 23 s,and the defects were eliminated.
