摘　　要：利用六西格玛管理提供的工具,对铸管公司1#350m3高炉的生铁含硅量进行了系统分析,找出了影响生铁含硅量的根本原因是煤比、料批、炉顶压力、焦炭灰分及料制。为此,制定了相应的改进方案,改进后生铁含硅量平均降到了0.39%以下。The pig iron silica content of The Cast Tube Co.＇s No.1 350 m^3 blast furnace is analyzed systemically by using six sigma management tools. The essential reasons of influencing pig iron silica content are found out. They are coal ratio, material charge, furnace top preasure, coke ash and charging system. Aiming at those essential reasons, corresponding improvement measurements are adopted, Then the average pig iron silica content is now below 0.39% after improvement,
