The effects of non or slightly caking coal amount of blended coal and permeability of coke on coke strength have been reviewed. The optimal process control management index for the coke oven has been proposed not by the vitrinite reflactance but by the thermal plasticity based on the mechanism analysis of carbonization. The fissure formation mechanism has been clarified. The national project of SCOPE21 has been reviewed. An increase of plasticity has been proved by the experimentation of rapid heating rate process or mechanical pressurization. The mechanism of volume destruction and surface destruction has been also clarified. The simulation method of coke abrasion mechanism has been proposed in the raceway. The elucidation of a strength formation mechanism, measurement of the strength during heating process, and the estimation method of coke strength have been also shown.
