METHOD FOR REPAIRING FURNACE WALL OF CARBONIZING CHAMBER

摘要

PROBLEM TO BE SOLVED: To provide a method for repairing a furnace wall of a carbonizing chamber in which smoothness of a repairing surface of a repairing part is further improved compared with a conventional method and increase of extrusion resistance in coke extrusion is suppressed and the life of the carbonizing chamber can be prolonged. SOLUTION: The method for repairing the furnace wall of the carbonizing chamber comprises repairing the furnace wall by blowing a flame-spraying raw material into a damaged part 12 of the furnace wall of the carbonizing chamber 10 in a belt-like state. In the repairing method, blowing of the flame-spraying raw material is carried out in a state laminated several times and a flame-spraying raw material forming the following layer toward a valley part 32 between the flame-spraying raw materials formed by previous layer.
