In coke-making, coke strength is an important parameter. Generally, the coke strength before or after CO_2 gasification reaction, is evaluated. Particularly, since the coke strength after CO_2 gasification reaction gives information on the state of coke in the blast furnace, it is useful for the operation. The objective of this work was to estimate the coke strength after gasification (MSI, Micro Strength Index) by using image analysis of coke cross-sectional image. In the cross-sectional image of gasified coke, there were two parts, "Connected coke-matrix part" and "Isolated coke-matrix part". The connected coke-matrix part was mainly located in the central part of the coke, and it connected with one part, and it significantly reacted and did not connected. It was found that there was a good correlation between the MSI and the area percentage of isolated coke-matrix part.
