熔模铸钢件缩孔(松)的防止
摘要
结合生产实例
系统阐述了防止熔模铸钢件缩孔 (松 )的主要措施 :其一是转移
即将缩孔由铸件中转移到浇注补缩系统中 ;其二是分散
即将缩孔分散成许多细微的缩松
Abstract
The key measutes for preventing shrinkage hole (porosity) in investment steel castings were expounded systemically based on actual production: (1) transfening: shrinkage holes transferred from casting into gating feeding system
(2) dispersion: shrinkage hole dispersed into much small shrinkage porosity.
