摘　　要：研究了铸铁内加微锡对铸铁的影响。经过试验研究并对结果进行的分析和比较,肯定了加微锡对铸铁内部组织的改变有一定的影响,不仅改变了铸铁内部的组织,还提高了铸铁的一些性能。铸铁内加微锡既经济又环保,为改变铸铁的性能起到事半功倍的作用。为了保证实用性,试验采用了最普通和最常规的熔炼和浇注方法,使试验更接近实际生产,在实际生产上也更便于应用操作。The paper describes a series of experimental research of adding trace amounts of Sn into cast irons. The results show Sn not only changes the internal organization, but also improves the performance of cast irons. Adding trace amounts of Sn is both economical and environmental friendly. In order to guarantee the practicability, the most common and conventional melting and pouring method is adopted , which makes the test more close to the actual production and makes it more available to operation in the actual production.
