摘要
概述了微量铋锑在大断面球铁中的作用。通过在生产条件下进行的模拟试验，总结出大断面球铁铋、 锑的临界加入量，且对稀土元素中和铋、锑的有害性作出了定量的评价。列举了部分大断面球铁铸件应用铋、 锑的生产实例。
The effect of trace Bi and Sb in heavy section ductile iron casting was briefed. According to the results of simulated experiment under productive conditions, the critical addtion amout of Bi and Sb was determined, and the capacity of rare earths to neutralize the deteriorative effect of Bi and Sb was quantitatively evaluated. The examples of applying Bi and Sb to the production of some heavy section ductile iron castings were given.
