Abstract

Abstract

In iron ore sintering process,iron ore liquid fluidity property has a critical impact on sinter quality.Liquid phase fluidity experiments of imported iron ore are carried out by using high temperature characteristic apparatus for iron ore.Influencing factors that affect liquid phase fluidity are elucidated and the characteristic of pore microstructure is also investigated.Results show that liquid phase fluidity of imported iron ore was mainly influenced by SiO₂,Al₂O₃ content of iron ore and added CaO content.Based on this finding,chemical composition factor of liquid phase fluidity was put forward.Furthermore,microstructure observation on pore in the liquid phase indicates that withthe increase of liquid phase fluidity,pore shows a higher degree of coalescing,and the roundness of pore structure is also improved.
