Coke oven chute masonry method

Abstract

The invention relates to the field of coking furnace ramp masonry construction and in particular relates to a coking furnace ramp masonry method. The coking furnace ramp masonry method is characterized by comprising the following steps: firstly, prefabricating a plurality of devices for pre-controlling positions of ramp holes in coking furnace ramp construction according to the longitudinal length of a coking furnace ramp masonry body and an effective operating range of straight line markers; secondly, constructing a coking furnace ramp; thirdly, measuring the sizes of the ramp holes, namely measuring the size of the ramp hole of each layer after each layer of ramp is constructed, and rectifying and reforming the part which does not meet the quality requirements; and fourthly, cleaning the insides of the ramp holes, namely cleaning the insides of the ramp holes after the multi-layer ramp is constructed each time. According to the method, the positions of the ramp holes can be well controlled and ash in the holes can be removed during ramp construction, so that the masonry quality of the coking furnace ramp is improved, the first qualification rate of the coking furnace ramp is increased, and the material and labor loss caused by a large quantity of rework is avoided.

Description

technical field [0001] The invention relates to the field of coke oven chute masonry construction, in particular to a coke oven chute masonry method. Background technique [0002] The coke oven chute is the channel connecting the regenerator and the combustion chamber. Thousands of chute openings and brick gas channels are distributed in it. The structure is relatively complicated. It is the core part of the coke oven. directly affect the service life of the coke oven. [0003] The ramp masonry usually uses horizontal marking boards to control the center line of each main single wall, and tracks the elevation line of each brick layer through measurement. For the ramp opening, the first layer of ramp opening is released from the longitudinal center line of the coke oven using the ramp opening ruler rod. Brick laying controls the side line. When laying bricks, first build the chute opening according to the furnace head belt line, and then build the surrounding bricks. The ch...

Problems solved by technology

Since the wooden stick or steel bar cannot extend downward along the radian of the chute, the cleaning is not in place, the cleaning efficiency is relatively low, and all the gray scars removed are missed to the lower chute

In some coke ovens, the regenerator is a multi-section partition structure. After the checker bricks inside are built, the ramp is built, and a layer of film is laid on the surface of the checker bricks to facilitate the ash cleaning in the future. If the ash is not removed as much as possible, the film will be damaged during cleaning, which greatly increases the possibility of blockage of checker bricks
