In our previous paper, a new measurement method for the coal adhesion property called “surface tension of semi-coke” was devised. The surface tension of a semi-coke sample obtained by heat treatment of a coal sample at 500°C was measured as a unique adhesion property. Conventionally, it has been thought that adhesion is dominant under a low MF (Gieseler maximum fluidity) condition. Moreover, it is important for effective coal utilization to develop a technique that enables production of high strength coke under low MF conditions, which has been thought to deteriorate coke strength. However, in the previous paper, the effect of surface tension on coke strength was investigated only under a single MF condition without changing the level of MF.
