Method for clearing off brick residues at broken holes in wall of coke oven hot repair carbonization chamber

Abstract

The invention provides a method for clearing off brick residues at broken holes in wall of a coke oven hot repair carbonization chamber. The method comprises the following steps: the construction workers observe an elevation position at the broken holes, determining the height and depth of the broken holes in the carbonization chamber, a rocker arm is manipulated, a sight hole is aligned to the broken holes in wall of the carbonization chamber, the broken holes image information can be obtained through a high temperature camera; damaged bricks which are characterized in that the outer bricks are small and inner bricks are large at the broken holes in wall of the carbonization chamber are cleaned by observating; the sight hole is aligned to the broken holes in wall of the carbonization chamber for checking the broken holes, the broken holes image information can be obtained, a hot repair plan is made, and then a brick filling and spraying material gunning scheme is determined. The method uses the carbonization chamber wall brick slag with the rocker arm manipulated outside a furnace, the method can be directly carried out for cleaning off broken brick residues of the internal wall body of the carbonization chamber under the conditions that operators do not need to enter the carbonization chamber and the temperature of the carbonization chamber is not reduced.

Description

technical field [0001] The invention relates to the technical field of metallurgical production, in particular to a method for cleaning brick slag at holes in walls of coke oven hot repair carbonization chambers. 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 wall repair of the carbonization chamber generally uses filling bricks to fill the holes first, and then uses gunning materials for gunning repair. The damaged surface of the bricks should be small inside and large outside or straight. After gunning, the wall surface maintains its thickness. However, there are also situations where the damaged surface of ...
