【摘要】 以国内外近年来在灰口铸铁中Ｓｉ／Ｃ比的影响的研究成果为依据，通过综合考虑Ｍｎ／Ｓ比、碳当量和Ｓｉ／Ｃ比对灰口铸铁力学性能的影响，采用正交试验方法设计实验方案，并对实验结果进行计算机方差分析和线性回归处理，提出了机械性能与成分之间的数学模式，预测了高强度灰口铸铁的最佳成分，并探讨了进一步开发灰口铸铁性能潜力的可能．更多还原

【Abstract】 Based on the recant research of the ratio of Si and C in gray cast iron andcomprehensively considering the influence of the ratio of Mn and S,carbon equvalent andthe ratio of Si and C on meChanical nature of gray cast iron.the orthogonal method isusedto design the experiment scheme, experiment results are dealt with computer analysis of variance. the methematical model betWeen mechanical nature and composition isset up. the optimum compostion of high strength gray cast iron is estimable; and the further development of potential nature of soy cast iron is studied.更多还原
