| 摘 要： | 介绍了灰铸铁、球墨铸铁中微量杂质元素的不利影响及其限量,并对Sn、Sb、Cr、Mo、V、Ti、Al等元素作了补充说明。简述了铸造用高纯生铁的含义:一种Mn、P、S、Ti含量低、特定微量元素含量很低的生铁,指出铸造用高纯生铁中微量元素含量明显低于铸铁中微量杂质元素的限量。

| Abstract: | The adverse effects of impurity microelements in gray iron and ductile iron and their limits were introduced,other elements,such as Sn,Sb,Cr, Mo,V,Ti,Al etc.,were also explained. High purity pig iron for foundry is low content for Mn,P,S,Ti and some given Microelements. Microelements in high purity pig iron for foundry is much lower than limits in cast iron. |

| Keywords: | gray iron ductile iron microelement limit |
