Abstract

The coking mechanism is considered as a process that the pulverized coal is changed into a lump of porous carbon structure after it is softened and melted with thermally decomposition by heating. From this point of view, the following items are investigated.<BR>(1) A bonding pattern for lumping the pulverized coal and a mechanism for the distribution of coke porosity across the oven width.<BR>(2) Analysis of affecting factors of an inherent strength and grafitization which are important for the evaluation of coke qualities.
