Analysis of influencing factors of sulfur dioxide in pelletizing process based on stepwise regression method
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.
