Novel method for building slope air course of coke dry quenching furnace

Abstract

The invention relates to the technical field of coke dry quenching production processes, particularly provides a novel method for building a slope air course of a coke dry quenching furnace. The method comprises the following steps of: controlling the elevation of each layer of bricks for building the bracket of the slope air course by adopting a special control plate, filling mortar joints, and only building four layers each day at a building temperature of 5-35 DEG C to ensure that the top elevation of the bracket reaches design requirements and the mortar joints reach a certain strength; discharging a shaft line from each bracket, marking on the bracket, upward leading along a building height, ensuring that the shaft line of the bracket meets design, placing and stressing an overhead brick uniformly; and in the process of building the overhead brick, arranging a steel support fixing frame which can bear a large load for decomposing the stress of the bracket of the slope air course. According to the invention, the quality accidents of the coke dry quenching furnace that the brickworks in a lower slope air course area deform, collapse and the like in the building process of an annular air course, and the building qualities of the slope air course, an upper annular air course and a pre-storing section are ensured so that the quality of the brickworks in the slope air course area can reach code requirements.

Description

technical field [0001] The invention relates to the technical field of dry quenching coke production technology, in particular to a method for building a dry quenching furnace chute. Background technique [0002] The CDQ is an essential part of the CDQ production process line of the coking plant, and it is also a new domestic process. It is the coke produced by coking in the coke oven that is CDQ in the CDQ. The conventional method of masonry for CDQ furnace chute is: after the lower part of the chute is positioned, the masonry is completed at one time, and wooden beams are used as temporary support frames for the annular air duct wall. [0003] The disadvantages of this method are: the elevation of the top of the corbel is difficult to meet the design requirements, the axis of the corbel often deviates, and the wooden support frame cannot fundamentally resolve the large load of the annular air duct wall; the corbel area of ​​the ramp is easily deformed and collapsed . The...

Problems solved by technology

[0004] The technical problem to be solved by the present invention is: in view of the above-mentioned present situation, it aims to provide a new method for effectively laying bricks on the CDQ furnace chute to ensure the masonry construction quality of the chute, the upper annular air duct and the pre-stored section, During the use of the CDQ furnace, the chute area will not be deformed, cracks and collapse quality accidents will not occur, and economic losses caused by quality accidents will be avoided
