Problems solved by technology

Even after the carbonization chamber is cooled down, it is not suitable for manual operation. The gas and toxic gas content in the carbonization chamber seriously exceeds the standard, which is not conducive to construction. Moreover, after the carbonization chamber cools down, it may cause shrinkage and settlement of the hole in the wall, causing the wall to burst and expand. fill range

Abstract

The invention provides a method for hot repairing of local damage of the coking chamber wall of a coke oven. The method includes the following steps: opening the gate of a coke oven, observing the coking chamber wall, and making a gun head guide rail by adopting CAD software; processing a filling repairing brick, determining the position of a rocker arm movable supporting frame, and erecting a lifting platform; operating an extension pole to carry out bonded spray repairing on a filling seam by the gun head; loosening a filling brick clamp, moving a rocker arm, aligning the spray repairing end of a surface filling spray material conveying tube with a filling brick, and carrying out leveling spray repairing; and observing the repairing effect, and archiving. The method reduces the occurrence probability of safety accidents in construction work, effectively alleviates the harms of high temperature, gas and toxic gases to human bodies, saves the repairing time and the workload for repairing secondary damage caused by cooling, greatly reduces the labor intensity, and improves the work efficiency.

Description

technical field [0001] The invention relates to the technical field of metallurgical production, in particular to a method for thermally repairing a partially damaged wall of a carbonization chamber of a coke oven. Background technique [0002] In the actual production process of the coke oven, due to the long-term friction between the wall surface of the carbonization chamber and the coal block, the wall surface of the carbonization chamber is partially worn and even has holes. In order not to affect production, it is necessary to repair or replace the holes in the wall of the carbonization chamber in a hot environment. The prior art is to stop the heating of several combustion chamber walls to reduce the temperature of the carbonization chamber wall from 1500 degrees to 400 degrees, and construction workers wear heat-resistant clothing to manually dig and mend. Even after the carbonization chamber is cooled down, it is not suitable for manual operation. The gas and toxic ...
