Coke strength is mainly determined by defects in coke. In order to improve coke strength, control of formation of defects during carbonization is important. When dilatation of blended coal is low, connected pore derived from large particle of high dilatation coal is major defect determining coke strength. On the other hand, when dilatation of blended coal is high, crack around large inertinite texture is major defect. It is clarified that coke strength can be improved by selective crushing of the coal that becomes the cause of major defects in coke.
