To evaluate condition and distribution of reduction degree and gas permeability in ore layer, examinations of high temperature properties with various ore layer thickness were executed. Gas permeability begins to decrease from the upper part of ore layer, where melt with more FeO is formed with low reduction degree. Experimental results show that the difference of reduction degree in ore layer of examination of high temperature properties is about 40% at 1200°C. Estimation with mathematical model indicates that difference of reduction degree in ore layer increases with decreasing gas flow rate.
