Title:
METHOD FOR EVALUATING INTER-COAL ADHESION
Document Type and Number:
WIPO Patent Application WO/2013/145677
Kind Code:
A1
Abstract:
Provided is a technology that evaluates the affinity of coals in coke production and evaluates adhesion strength when carbonizing two types of coal on the basis of the physical properties of coal in order to produce coke having a desired strength by blending coals taking into consideration affinity. The surface tension is measured of two types of semi-coke obtained by heat-treating two types of coal, obtaining the measured values thereof. On the basis of the difference in the obtained two surface tension measured values, the suitability of the adhesion between the two types of coal is evaluated.
