摘　　要：综述了硅碳比对灰铸铁性能的影响的不同结果。似乎还需弄清硅碳比对灰铸铁拉伸性能的影响。参考文献中所报道的拉伸强度随硅碳比的提高而提高,同样也受含锰量的提高,炉料中废钢配比的提高,出铁温度的提高等的影响。Different results on the influence of Si : C ratio on the properties of gray cast iron was surveyed. It seemed that the influence of Si'C ratio on the tensile property of gray cast iron still need to be clarifyed. The increasing of tensile strength by raising Si:C ratio reported in the references is also dire to the effects of increasing manganese content, increasing stell scrap in the charge materials or increasing taping temperature from the cupola.

关 键 词：灰铸铁 硅碳比 拉伸强度
