摘要
本文概述了微量铋、锑元素在大断面球铁生产中的作用。建议在铁素体基体球铁中加入0．008％-0．010％Bi并控制Re残／Bi在1．4～1．9的范围；在珠光体基体球铁中加入0．01％-0．02％Sb并控制Re残/Sb在1．2～2．5的范围，可使这两类球铁的综合性能达到最佳。
The effect of trace elements Bi and Sb on production of s.g.iron with large section has been summarized with proposal that for an optimal comprehensive performance of two types of s.g. iron, 0.008%-0.010% Bi should be added into that with ferrous base and the ratio of Re residual/Bi be controlled within 1.4-1.9 while 0.01%-0.02%Sb should be added into that with pearlite base and the ratio of Re residual/Sb be controlled within 1.2-2.5.
