Chute corbel pillar masonry structure of dry quenching furnace

Abstract

The invention discloses a chute corbel pillar masonry structure of a dry quenching furnace. The structure is characterized by comprising a plurality of layers of double-row corbel pillar bricks whichare alternately arranged in the height direction, wherein adjacent corbel pillar bricks of each layer of double-row corbel pillar bricks in the length direction extend along an axial line and are in plane fit, and the adjacent corbel pillar bricks in the width direction are arranged in parallel and are in buckled connection through a brick ditch and a brick tongue of a B type brick; the adjacent head-on corbel pillar bricks of the upper layer and the lower layer are in buckled connection by a brick ditch and a brick tongue of a D type brick, a brick ditch and a brick tongue of an H type brick,a brick ditch and a brick tongue of an S type brick and / or a brick ditch and a brick tongue of a B type brick, and other adjacent corbel pillar bricks of the upper layer and the lower layer are in buckled connection by the brick ditches and the brick tongues of the B type bricks, the brick ditches and the brick tongues of the H type bricks and the brick ditches and the brick tongues of the S typebricks. The engagement between the bricks of the whole corbel pillar is sufficient and reasonable; the possibility of crackling of the head-on bricks of the corbel pillar is reduced by mutual engagement between the upper layer and the lower layer.

Description

technical field [0001] The invention belongs to the technical field of refractory materials, and in particular relates to a masonry structure of a chute corbel pillar of a CDQ furnace. Background technique [0002] CDQ furnace (abbreviation: CDQ furnace) is an important device of CDQ system. The upper part of the CDQ furnace is a pre-storage room and an annular air duct surrounding the pre-storage room and communicating with the pre-storage room. The lower part is a cooling room. The structure connecting the previous and the next, its components mainly include corbels, which are the key parts, and the inclined corbels of the double brick structure, after running for a period of time, there will be problems of brick displacement and serious cracking of the facing brick joints. The corbel pillars support the weight of the circular air duct of the CDQ furnace of about 200 tons. If the cracking of the pillars is not solved in time, the long-term friction between the coke and th...

Problems solved by technology

Although the above-mentioned several chute corbels have been improved and have achieved certain effects, they still cannot meet the production needs of the CDQ furnace's service life.
