本文研究了用富铈稀土硅铁(Ce10)作为孕育剂以考察其在高Si/C比铸铁中的孕育效果。Ce10的化学成分(％)为铈9.75,其它稀土12.2,硅44.04,钙1.1,铁余量。一、试验方法用三种碳当量的铸铁:低碳当量3.0～3.2％,中碳当量3.4～3.6％,高碳当量3.7～4.0％,以考查铈稀土Ce10的孕育效果 In this paper, cerium-rich rare earth ferrosilicon (Ce10) was used as inoculant to investigate its inoculation effect in high Si / C ratio cast iron. The chemical composition (%) of Ce10 is cerium 9.75, other rare earths 12.2, silicon 44.04, calcium 1.1, iron balance. First, the test method with three kinds of carbon equivalent of cast iron: low carbon equivalent of 3.0 to 3.2%, carbon equivalent of 3.4 to 3.6%, high carbon equivalent of 3.7 to 4.0% in order to examine cerium rare earth Ce10 inoculation effect
