Change in the blowing pressure applied to the sintering bed (for the preparation of row materials for ISP) was examined by the experiment using a sinter pot and a mathematical model considering gas-flow across the bed. The results obtained were as follows: (1) A pressure drop of the sintering bed changes as the sintering reaction proceeds. It increases at the beginning of the oxidized reaction when the temperature of the bed is still low.Then it decreases as the progress of reaction accompanied by the increase in the bed temperature. (2) The pressure drop of the bed during the sintering process was mainly attributed to a drying zone, and was comparatively low in the reaction and the cooling zones. (3) Based on the Erugens equation, the change in the pressure drop during sintering can be explained by assuming the decrease of an apparent fractional void volume in the drying zone.
