一、前言统计推断是质量管理活动中一项很重要的手段,已被国内外的实践所证明。由于钢铁生产过程的复杂性和特殊性,统计推断的应用更呈现出明显的效能。本文通过在烧结煤气点火系统中运用统计推断原理优化点火工艺参数节约能源的实践,说明在钢铁生产过程中应用统计推断可为解决生产、工艺、操作中的薄弱环节或工艺理论探讨提供科学依据。最后就如何推广应用统计推断法提出本人的一点见解。二、工序状况分析武钢烧结厂1986年时拥有烧结机8台,年产烧结矿520万吨以上,点火煤气消耗量为
I. Preface Statistical inference is a very important measure in quality management activities and has been proved by the practice at home and abroad. Due to the complexity and particularity of the steel production process, the application of statistical inference shows more obvious efficiency. In this paper, we use the principle of statistical inference to optimize the parameters of ignition process to save energy. The application of statistical inference in steel production process can provide a scientific basis for solving the weak links in production, process and operation or the theory of process. Finally, how to promote the use of statistical inference put forward my own point of view. Second, the process status analysis Wusigang sintering plant in 1986 with 8 sintering machines, with an annual output of 5.2 million tons of sinter, ignition gas consumption was
