PROBLEM TO BE SOLVED: To enable the influence of the dislocation of an oven wall of a carbonization chamber in the oven width direction at extrusion of cokes, and the influence of a plurality of uneven sites of the oven wall scattered in the longitudinal direction affecting on the extrusion load to be evaluated quantitatively, and to enable the load distribution of the uneven sites at which locally concentrated load is apt to be caused to be evaluated temporally continuously and quantitatively. SOLUTION: The extrusion load when right and left sidewalls are dislocated is evaluated by extruding the cokes while allowing a reaction force to act on the cokes when extruding the test cokes arranged between the right and left sidewalls from one side to the other side along the sidewalls so that the right and left sidewalls may be dislocated in the direction perpendicular to the extrusion direction of the cokes cake when a force not lower than a prescribed value is added, measuring each of the extrusion force at the extrusion and the receiving force when the reaction force acts, and evaluating the extrusion load when the right and left sidewalls are dislocated based on the measured values and the value of the reaction force.
