The hot permeability of aggromerates of iron ores (pellets, brickets or sinter) was measured. As result of the measurement, it was confirmed that the effect of the component particles was predominant at normal temperature, but it became minimized at 700∿800℃ by coagulation of particles each other. The correlation between the reducibillity versus porosity and permeability was studied. According to the author's investigation, this relation can be summarized the following equation of regression plane : R=-269.1S-8.6P-0.3A+417.9 Where, R=reductivity, S=diameter of pulverised ore, P=porosity, and A=permeability in normal. At high temperatures, the size of pulverised ore is not so effective for permeability, furthermore the porosity and permeability of the different sizes were in negative correlation.
