Beschreibung
Zusammenfassung:	The present invention relates to a warm strength predicting method of coke, which comprises: a step of manufacturing a coke which carbonizes the coal with the assorted coal type and manufactures the coke; a step of measuring a warm strength which measures the warm strength of the previously manufactured coke; a step of analyzing a structure which analyzes a structure of previously manufactured coke; a step of drawing a correlation by comparing the warm strength of the coke and the structure of the coke; a step of estimating the warm strength which estimates the warm strength of the coke according to the correlation which is previously drawn. The present invention is capable of estimating the warm strength even the particle size of coke is less than 19 mm or the quantity of the coke sample is less than 200 g. [Reference numerals] (AA) coke warm strength = -0.32 * low strength structure content +74.9; (BB) warm strength(%); (CC) low strength structure content(%, Isotropic+Fine Mosaic)
