The results showed that in BF scaffolding accretion operation, the coke in tuyere area cracks seriously, the permeability and liquid-penetration of the deadman get worse and the content of alkali metal is high; After getting rid of the nodulation, the average size of tuyere coke has a decrease trend with the increase of PCI ratio, and the coke size from the edge to centre of hearth reduces; The slag composition varies in tuyere area, and the slag alkali is lower in edge than that in centre.Read More
