Japanese Patent JP7323741

B2

To provide a repair method of a coke oven carbonization chamber oven wall which has no risk of damage to function of a combustion chamber, is excellent in work efficiency, rapid, and inexpensive, and can deal with a large breakage hole.SOLUTION: A method for repairing a breakage hole 11 passing through an oven wall 10 dividing a coke oven into a carbonization chamber and a combustion chamber comprises the steps of: holding a blanket-like heat insulation material 12 of a maximum use temperature of 1000°C or higher and 1300°C or lower with a heat insulation material holding tool 14, inserting the material into the carbonization chamber through an oven port of the carbonization chamber or a coal loading port provided on a top of the carbonization chamber, and fitting the heat insulation material 12 into the breakage hole 11 using the heat insulation material holding tool 14; inserting a thermal spray device 15 through the oven port of the carbonization chamber into the carbonization chamber and carrying out thermal spray on a boundary between the heat insulation material 12 and the breakage hole 11 using the thermal spray device 15 to fix the heat insulation material 12 in the breakage hole 11; and forming a thermal spray layer 17 on and around the heat insulation material 12 using the thermal spray device 15 to fill the breakage hole 11.SELECTED DRAWING: Figure 3
