摘　　要：针对可锻铸铁管路连接件生产中的缩松缺陷,从铸件结构及其凝固特性、浇注系统及其设计等方面进行了分析,提出了解决缩松的工艺措施:浇注位置由端面改在弯角处,冒口顶部与上型中的管件高度持平等,取得了较好的效果。In view of the shrinkage defects in the production of malleable iron pipe connection,the casting structure and solidification characteristics,pouring system and its design were analyzed,and the technological measures to solve the shrinkage defects were put forward:the pouring position was changed from the end face to the bend Angle,and the top of riser was equal to the height of pipe fitting in the upper mold,and good results were obtained.
