摘要

Oven wall three-dimensional profile data (701) indicating the quantity of roughnessall over the right and left oven walls (14R and 14L) of a carbonizing chamber (11)is created by using an image signal obtained by a wall-surface observing device(200). The oven wall three-dimensional profile data (701) is used to determinea resistance index (k), which is determined by indexing the resistance receivedby coke (15) extruded by the rising gradient of the oven walls (14). It can be confirmedthat the resistance index (k) and an extrusion load are correlated. Therefore,the state of the oven walls (14) to exert influences on the extrusion load can bequantitatively evaluated.
