抄録

In order to clarify degradation of coke in the cohesive zone and the dripping zone of a blast furnace, the fundamental experiment about coke degradation reacted to molten FeO was carried out. The difference of coke degradation reacted to molten FeO and CO₂ gas is discussed. The results are as follows.<BR>(1) Coke reacted to molten FeO forms dimple and thin reacted layer locally. Coke reacted to CO₂ gas forms thick reacted layer around lumpy coke.<BR>(2) Coke reacted to CO₂ gas discharges more fine coke than coke reacted to molten FeO. Coke reacted to molten FeO discharges particles.<BR>(3) Fine ratio of coke reacted to molten FeO is suppressed with increasing coke strength.
