摘要
综合评述有关球墨铸铁凝固特性、凝固过程体积变化和缩孔、缩松形成机理的文献资料。笔者还结合本人的工作实践就缩孔、缩松的预防提出了看法。
The li teratures on the solidification and shrinkage characteristics of ductile iron,v olume variation during solidification process and the formation mechanism of sh rinkage porosity/cavity of ductile iron were summarized and reviewd.Combining with his own working practice,the writer also proposed some suggestions about how to prevent the shrinkage porosity and cavity.
