摘　　要：铁水中硅和硫的含量是高炉炼铁的重要指标之一。通过六西格玛技术对硅、硫含量的变化,判断其是否稳定,确定出现不稳定的点或区域,从而为进一步分析造成不稳定的因素、制定合理的高炉操作指导提供依据。在分析过程中采用了六西格玛分析软件Minitab,分析结果表明,能够很好地达到判断稳定性的目的。The content of silicon and sulfur in hot metal is one of the important indexes for blast furnace iron-making process. By means of the six-sigma data analysis, the stability of content of silicon and sulfur was analyzed. The unstable point or stage of production process was ensured. Thus, the factors affecting the variation of the content of silicon and sulfur can be assured. Minitab software of the six-sigma quality analysis is used and its result is enough to realize the goal for judging the process stability.
