逐步回归法对钢铁企业球团工序SO2的影响因素分析
Analysis of influencing factors of sulfur dioxide in pelletizing process based on stepwise regression method
以某钢铁企业球团工序提供的数据为基础,分析了球团矿生产过程及原料中铁精矿、煤粉、粘结剂用量、溶剂用量4个因素对SO2排放浓度的影响,运用SPSS软件对各影响因素进行逐步法回归分析,建立影响球团工序中SO2平衡的线性回归模型.
Based on the data provided by the pelletizing process of an iron and steel enterprise, this paper analyzes the influence of the pelletizing process and the consumption of iron concentrate, pulverized coal, binder and solvent on the emission concentration of sulfur dioxide. The stepwise regression analysis of each influencing factor is carried out by using SPSS software, and a linear regression model affecting the balance of sulfur dioxide in the pellet process is established.
