抄録

Previous researches on coke strength and reactivity have been performed without consideration of coke property distribution across the coke oven width. However, the importance and decisive effect of the coke property distribution across the coke oven width was confirmed both by experiments and by the analysis of measured results.<BR>The coke produced by a 250 kg electric test coke oven was devided into 10 sections across the oven width and the various coke property distributions were measured as well as coke strength and reactivity of whole samples.<BR>Based on the analysis of measured coke properties, it is found that coke strength can be basically evaluated by the porous material strength formula based on porosity and inherent strength. Furthermore it is found that weight loss by reaction of coke can be evaluated from porosity and the degree of graphitization, while coke strength after reaction with CO2 gas can be evaluated from porosity, inherent strength, and the degree of graphitization.
