摘要

针对大管径离心球墨铸铁管内壁渣多

伸长率、压扁率合格率低等问题

应用低稀土、低硅球化剂进行了试验

取得了良好的效果

结果显示

铸管渣量减少

伸长率、压扁率合格率分别提高了 2 5 .3 %和 19.4%

Abstract

A Mg nodulizer with low RE and silicon was developed to overcome the difficulties in the large centrifugal ductile iron pipes

including much slag inside the wall

low elongation and flattening. The results showed that the amounts of slag decrease and the elongation and flattening increase by 25.3% and 19.4% respectively.
