Abstract：Two series of low silica sinter samples with different basicity and MgO content were prepared by sintering pot tests. XRD and TEM were used to characterize the structure and surface morphology of samples: a calcium ferrite and iron oxide content has undergone significant changes with the increasement of alkalinity and MgO content. Structure of pore ??changes more complex from columnar structure to Mesh erosion structure. Surface fractal dimension of sinter pore were calculated by monofractal software and surface fractal model respectively([Dss]and[Dsv]): Surface fractal dimension increases with the improvement of alkalinity and MgO content, [Dsv] and [Rsv] calculated by monofractal software are greater than [Dss] and [Rss] calculated by surface fractal model, which indicate that the surface fractal model can reflect more details, and has better correlationso. So surface fractal model can substitute traditional monofractal software to characterize the fractal structure of sinter pore surface, to solve the difficulties and limitations of the pore surface shooting.
