To analyze some primary factors that determine the driving rate of the blast furnace, the characteristics of pressure drop in the countercurrent moving bed were studied. The following results were obtained : 1. The flow of particles seemed to be the piston flow up to channeling state. 2. The Ergun's equation could be applied to the pressure drop of room temperature blast up to channeling state. 3. The differences of the characteristics between fixed bed and moving bed were observed to be in, (1) the packing state in the upper parts of packed column, (2) the process of the development of channeling state. 4. The observed pressure drop of the hot blast was a little higher for lower air velocity, but a little lower for higher air velocity than that of cold blast at the same velocity. The Ergun's equation could also be applied to the pressure drop of hot blast up to channeling state.
