PROBLEM TO BE SOLVED: To provide a manufacturing method of coke capable of optimizing pulverization particle size by a simple method and increasing the strength of the manufactured coke without the need for any special device.SOLUTION: There is provided a manufacturing method of coke for manufacturing coke by dry distillation of coal charge obtained by blending a plurality of kinds of single coals, including a process A for obtaining an index Iand an index Iof each single coal, a process B for calculating a value [I-I] of each single coal and a process for pulverizing a single coal determined that at least its value Y is the largest by calculating the value Y exhibiting a pulverization effect based on a formula Y=e×X+f×X+g when the calculated value [I-I] is smaller than a predetermined threshold or calculating the value Y based on a formula Y=h×X+i when the calculated value is the predetermined threshold or larger.SELECTED DRAWING: Figure 1 |
