A simulation model which enables the estimation of the carbonizing condition in a coke oven in view of both coke qualities and heat transfer, is proposed. The validity of the model is confirmed through both laboratory-scale and actual-scale coke ovens. The features of the model are described as follows ; (1) Density variation in the coal and coke zones across the oven width during carbonization is consecutively calculated and used as an input value for coke quality estimation and heat transfer calculation. (2) Porosity, micro-strength, and graphitization during carbonization are consecutively calculated and used as input values for the estimation of coke strength and reactivity. Coke strength is estimated with consideration of the effect of structual defect which may be caused by the incomplete bonding of coal particles.
