Abstract
Provided is a technique by which the compatibility between coals for cokemaking can be quantitatively determined to estimate the coke strength taking into account the compatibility and to select and blend coals based on the coke strength estimated taking into account the compatibility, thereby allowing the production of a coke with the desired strength. A method for blending coals for cokemaking includes predicting the strength of a coke to be produced from a blend of a plurality of coals based on a difference between the surface tensions of the plurality of coals after heat treatment and determining the types and proportions of the coals to be blended.
