The deterioration of coke in the blast furnace has been evaluated as the change in coke size due to reaction between coke and CO2 gas. To clarify the deterioration mechanism, a series of experiment has been carried out at each reaction temperature by using an apparatus for high temperature CO2 reaction.<BR>The main results obtaind are as follows.<BR>1) Based on the findings mentioned above, a model was developed for estimating the deterioration of coke strength by CO2 reaction.<BR>2) The model contained the influence of alkali in coke on deterioration of coke strength in the blast furnace.<BR>3) The deterioration of coke strength estimated by the model closely agreed with that measured at different reaction temperatures by using an apparatus for high temperature CO2 reaction.<BR>4) The influences of coke properties, operation condition in the blast furnace and alkali in coke on the deterioration of coke strength were discussed by using this model.
