预处理和孕育处理一直是球铁生产中的热门话题,本文所述的添加剂既可以作预处理剂用于原铁液的预处理,也可以作孕育剂用于球铁铁液的孕育处理。迄今,国内文献介绍较多的是硅铁、硅钙、石墨、钡、锶等添加剂的作用,关于碳化硅作添加剂的作用则介绍较少,为此摘要介绍R Zavadil等人的试验结果,供国内同行参考。题名及文中标题是编者添加的。 Pretreatment and inoculation has been a hot topic in the production of ductile iron. The additives described in this paper can be used as pretreatment agent for the pretreatment of the original liquid iron, but also as an inoculant for the inoculation of the ball iron liquid. So far, the domestic literature is more ferrosilicon, calcium silicate, graphite, barium, strontium and other additives, the role of additives on the silicon carbide is less, this summary of R Zavadil et al. Test results for Domestic counterparts reference. Title and title of the article is added by the editor.
