【摘要】 采用ProCAST软件,对KU-1004铸件的两套工艺方案从充型、凝固两个方面进行对比分析,并对顶注工艺的补缩系统进行优化设计,采用腰形冒口,按照模数比例增大冒口尺寸,扩大了补缩通道,将法兰根部的热节推移到冒口中去,有效地避免了铸件中缩孔、缩松的产生。更多还原

【Abstract】 Two kinds of technologies for KU-1004 casting from filling to solidification are analysed and compared based on ProCAST.Feeding system of top filling is optimized through adopting two waist risers,increasing the size of the risers according to modulus ratio and expanding the feeding access.The hot spots in the flange root are moved to the waist risers and the shrinkage and the porosity are avoided effectively.更多还原
