The pore distribution of low silica sinter ore samples with different basicity was measured by pressure mercury method,and the fractal characteristic of pore distribution was calculated with multifractal theory,then metallurgical properties were also obtained,finally,their relationship among them was discussed.The results show that the pore distribution has experienced a process from non-uniform to uniform with increasing alkalinity.When the basicity is 2.0,the spectral width Δα is minimum,multifractal structure is more uniform,fractal characteristics is better,the pore distribution is more uniform,and the pores are larger,which is helpful to improve metallurgical properties.The results also show that when the basicity is 2.0,its metallurgical properties are optimal.
