PROBLEM TO BE SOLVED: To provide a method for repairing an oven wall of a carbonization chamber of a coke oven by which the surface of a layer repaired by thermal spraying and formed at the damaged part of the oven wall of the carbonization chamber of the coke oven can be smoothened. SOLUTION: The surface of the layer repaired by the thermal spraying and previously formed at the damaged part of the oven wall of the carbonization chamber is heated to≥1,300°C when repairing the oven wall of the carbonization chamber of the coke oven. By the heating, the layer repaired by the thermal spraying is smoothened by forming a glass layer on the surface. Preferably, the surface of the layer repaired by the thermal spraying is heated by a flame of a mixed gas of an inflammable gas and a combustion-supporting gas. COPYRIGHT: (C)2006,JPO&NCIPI
