Quick repairing method for perforation of coke oven wall

Abstract

The invention discloses a quick repairing method for the perforation of a coke oven wall. The method comprises the following steps: determining a perforated carbonization chamber; pushing out coke inthe perforated carbonization chamber, opening a riser tube cap and an oven lid, cleaning the coke powder in the perforated carbonization chamber, and carrying out heat insulation on the upper part ofthe perforated carbonization chamber; measuring the size of the perforated part; placing zero-expansion bricks by using a brick holding tool, and carrying out dry building; restoring the heating of aperforated vertical flame path; carrying out secondary heat insulation on the perforated carbonization chamber; welding gaps between the zero-expansion bricks and the oven wall and gaps between bricks; and performing heating to restore production. The quick repairing method for the perforation of the coke oven wall has the advantages of effective prolongation of the service life of the coke oven,effective prevention of a repairing personnel from entering the carbonization chamber, avoiding of secondary damages caused by the temperature drop of the oven wall, effective improvement of the hot repairing efficiency of the coke oven, and great reduction of the labor intensity of the hot repairing personnel.

Description

technical field [0001] The invention relates to the field of coke oven thermal repair technology, in particular to a method for quickly repairing holes in the coke oven wall. Background technique [0002] During the use of the coke oven, the phenomenon of perforation of the coke oven wall often occurs. When the coke oven wall is perforated, the perforation needs to be repaired so that the coke oven can be used normally. [0003] In the prior art, when the furnace wall of the coke oven is perforated for hot repair, it is generally necessary to wait for the temperature of the furnace wall to drop to 800°C before repairing the furnace wall. Personnel put on heat-insulating radiation suits and professional gloves, and enter the carbonization chamber to perform thermal repairs on the perforated parts. [0004] In the existing furnace wall perforation repair method, since the hot repair personnel need to enter the carbonization chamber to carry out work, the temperature of the fu...

Problems solved by technology

[0004] In the existing furnace wall perforation repair method, since the hot repair personnel need to enter the carbonization chamber to carry out work, the temperature of the furnace wall needs to be cooled in advance during the hot repair operation of the coke oven wall perforation, resulting in low efficiency of the hot repair operation, and the hot repair personnel enter The carbonization chamber will cause secondary damage to the temperature drop of the furnace wall, and the labor intensity of the workers is high, which poses a safety hazard
