通过收集某钢厂2800 m3高炉的生产数据，结合六西格玛管理技术，对铁水硅含量及所选参数进行相关性分析、因果矩阵分析和回归分析，确定了铁水硅含量的主要影响因素有小焦比、冶炼强度、炉渣碱度和铁水温度，它们对硅含量的综合影响贡献率达81.5%。通过增加炼铁过程中小焦比的用量，提高炉渣碱度，并适当降低铁水温度和冶炼强度，铁水中硅含量最大值为0.497%，平均值为0.476%，下降0.05%。
通過收集某鋼廠2800 m3高爐的生產數據，結閤六西格瑪管理技術，對鐵水硅含量及所選參數進行相關性分析、因果矩陣分析和迴歸分析，確定瞭鐵水硅含量的主要影響因素有小焦比、冶煉彊度、爐渣堿度和鐵水溫度，它們對硅含量的綜閤影響貢獻率達81.5%。通過增加煉鐵過程中小焦比的用量，提高爐渣堿度，併適噹降低鐵水溫度和冶煉彊度，鐵水中硅含量最大值為0.497%，平均值為0.476%，下降0.05%。

In this article, the production data of 2 800 m3 BF in a steel plant were collected. Combined with the Six Sigma Management Method, the method of Causal matrix analysis, Correlation analysis and Regression analysis were used on the silicon content in hot metal and the parameters were selected by Minitab software. It can be determined that the silicon content in hot metal was mainly influenced by small particle coke rate, smelting intensity, slag basicity and hot metal temperature. The comprehensive contribution rate for silicon content in hot metal reached 81.5%. By increasing the amount of small coke rate and slag basicity, decreasing the hot metal temperature and smelting intensity appropriately in the ironmaking process, the maximum of silicon content in the hot metal was controlled up to 0.497%, the average of Si was up to 0.476%, it was decreased by 0.05%.
