description The relationship between charging principle and hearth activity of blast furnace has been clarified in this research. The voidage and diameter of coke in deadman which are related to charging principle serve as two pivotal factors for hearth activity. Discrete element method (DEM) analog simulation illustrates that both central and non-central coke charging result in the stratified structure of coke and ore in BF center. It is suggested to take non-central coke charging to promote central gas flow if the quality of raw materials meets the corresponding requirements. For the BF with poor raw materials, it is reasonable to employ central coke charging to keep the long-term stability of the production.
