摘要：

By simulating droplet formation and property in blast furnace, the effect of coke under different alkali metal loads on the droplet performance of furnace charge was investigated. The relations between alkali metal load and the maximum pressure difference (Δpmax) and the droplet eigenvalue (S) value were analyzed, respectively. The results indicate that the coke under alkali metal load affects the charge melt drops performance through catalyzing melting reaction of coke. The morphology of cokes after reaction shows that with the increase of alkali metal load, the number of stomatal on the coke surface increases and the size becomes larger, the erosion of coke surface becomes more severe, the strength of the coke decreases even down to zero, eventually the droplet performance of furnace charge can be affected, which make Δpmax and S deteriorate greatly. © 2017, Editorial Department of Journal of Northeastern University.
