Abrégé

Provided are a repair method and a repair device for a coke oven, with which, when bricks that form a wall of a combustion chamber of a coke oven are to be repaired while hot, an adjacent combustion chamber and remaining bricks in a portion not being repaired that are left without being dismantled will not bulge toward a carbonization chamber after the repair. The present invention is a coke oven repair method including: a confirmation step in which an oven wall of a combustion chamber that is adjacent to a combustion chamber to be restacked is examined, using a three-dimensional measuring instrument through an oven port, for unevenness to confirm whether the amount of bulging of the oven wall of the adjacent combustion chamber is less than a prescribed value; a restacking step in which, if it was confirmed in the confirmation step that the amount of bulging of the oven wall of the adjacent combustion chamber is less than the prescribed value, parts requiring repair of an oven wall of the combustion chamber to be restacked are dismantled, and oven wall bricks and binder bricks are stacked anew in the scope of the dismantling; and a step in which a pre-formed oven wall refractory aggregate and a pre-formed ceiling section refractory aggregate are used as a newly stacked oven wall and a ceiling section in the combustion chamber to be restacked.

Abrégé

This method for repairing a coke oven comprises: a confirmation step for observing, by using a three-dimensional measuring instrument from an oven port, the unevenness of a furnace wall of an adjacent non-replacement combustion chamber adjacent to one side surface of one replacement combustion chamber or a plurality of contiguous replacement combustion chambers, and of a furnace wall of an adjacent non-replacement combustion chamber adjacent to the other side surface, and confirming that the protruding amount of each of the furnace walls of the adjacent non-replacement combustion chambers is less than a prescribed value; a replacement step for, when it is confirmed in the confirmation step that the protruding amount of each of the furnace walls of the adjacent non-replacement combustion chambers is less than the prescribed value, dismantling a portion requiring repair of a furnace wall of the one replacement combustion chamber or the plurality of contiguous replacement combustion chambers, and stacking new furnace wall bricks and binder bricks in the dismantled range; and a step for using a furnace wall refractory aggregate molded in advance and a ceiling part refractory aggregate molded in advance as the furnace wall and a ceiling part for replacement to be new in the replacement combustion chamber.
