Abstract

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.

Key words

pelletizing process / SPSS software / gradually return / sulfur dioxide balance
