Coke strength is one of the most important factors for determining coke quality. A technology to manufacture good-quality coke from coal blends containing low-quality slightly caking or non-caking coals is strongly required. Technological developments to evaluate the coke strength easily are needed. A new image analysis for evaluation of coke strength was proposed. Coke-matrix connectivity was suggested as one of the determining factors of coke strength. Details of this new image analysis are presented.
