PURPOSE: A coke manufacturing method through the combination of coal is provided to improve a hitting rate of cold strength prediction and reduce the number of changing coal combination even if the cold strength of coke is lowered. CONSTITUTION: A coke manufacturing method through the combination of coal comprises a step of combining different kinds of coal at the predetermined rates according to the log maximum fluidity, strength index, and effective reflectivity section of the coal, a step of manufacturing coke using the combined coal, and a step of displaying the predetermined rates with corresponding coordinates on the screen of MES(Manufacturing Execution System). The log maximum fluidity, strength index, and effective reflectivity section are 2.3~2.5, 4.25~4.35, and 31~31.7%, respectively. |
