Method for repairing fusion holes in wall of carbonization chamber without cooling

Abstract

The invention relates to a method for repairing fusion holes in a wall of a carbonization chamber without cooling and belongs to the technical field of coke furnace repairing. The method has a technical scheme that an operator repairs a wall of a carbonization chamber without entering into the carbonization chamber; and in repairing, the operator uses a detection tool to detect fusion hole positions and carries out spray repairing from a vertical flame path on a furnace top to the interior of the carbonization chamber so that fusion holes in the wall are repaired with mud gradual solidification and thus the method breaks through a thinking way of wall repairing from a combustion chamber to a carbonization chamber, overturns the traditional method of repairing a furnace wall of a carbonization chamber, shortens repairing time and prolongs a coke furnace service life. The method provided by the invention has the advantages that a repairing rate is fast; a normal production order is not influenced; carbonization chamber wall repairing does not need cooling so that a coke furnace service life is prolonged; the method thoroughly overturns a thinking way of wall repairing from a carbonization chamber; a spray gun structure is modified so that the spray gun structure is more suitable for carbonization chamber fusion hole repairing; an application range of a semi-drying spray repairing device for spray repairing of a carbonization chamber wall is widened; and a baffle plate avoids spray repairing material splashing in spray repairing and improves a spray repairing rate.

Description

technical field [0001] The invention relates to a method for repairing a melt hole on the wall of a carbonization chamber without cooling down, and belongs to the technical field of coke oven repair. Background technique [0002] During the production process of the coke oven, as the age of the coke oven increases, the wall surface of the carbonization chamber is more worn and corroded, and melting holes are prone to appear, resulting in damage to the wall surface of the carbonization chamber, which affects the normal production order and the service life of the coke oven. The traditional repair method is: stop the production of the carbonization chamber that needs to be repaired, buffer the adjacent carbonization chamber, and perform partial digging and repair after cooling the carbonization chamber; the existing problems are: cumbersome operation, long repair time, affecting production, and the most important thing is that the furnace temperature drops greatly , Silica bri...

Problems solved by technology

[0002] During the production process of the coke oven, as the age of the coke oven increases, the wall surface of the carbonization chamber is worn and corroded, and melting holes are prone to appear, resulting in damage to the wall surface of the carbonization chamber, which affects the normal production order and the service life of the coke oven.

The traditional repair method is: stop the production of the carbonization chamber that needs to be repaired, buffer the adjacent carbonization chamber, and perform partial digging and repair after cooling the carbonization chamber; the existing problems are: cumbersome operation, long repair time, affecting production, and the most important thing is that the furnace temperature drops greatly , silica bricks are prone to crystal transformation, which affects the service life of the coke oven

There is also the method of repairing by ceramic welding. The existing problems are: the operation is cumbersome, requires high operating technology, and needs to be equipped with a ceramic welding machine, which requires a large investment.
