METHOD FOR ESTIMATING STRENGTH AFTER HOT REACTION OF COKE

摘要

PROBLEM TO BE SOLVED: To provide a method for estimating a strength after a hot reaction of coke.SOLUTION: A method for estimating a strength after a hot reaction of coke includes: performing binarizing processing of separating a coke cross-section image after a hot reaction to a coke substrate and substances other than the coke substrate; then dividing the coke substrate into pixel units; connecting a pixel having the coke substrate existed therein with a pixel having the coke substrate adjacent to the pixel existed therein; determining a coke substrate group having the largest area to be a connected substrate and determining the coke substrate other than the connected substrate to be an isolated substrate, of the coke substrate group formed by the connection; and substituting an area ratio of the isolated substrate with respect to the whole coke substrate into the following expression (1) to calculate the estimated value. Estimated value (%) of strength after hot reaction of coke=90-1/2×area ratio (%) of isolated substrate (1).SELECTED DRAWING: Figure 6
