Anti-slip structure for corbel bricks of dry quenching furnace

Abstract

The invention relates to a dry quenching furnace building process, in particular to a dry quenching furnace corbel brick anti-slip structure which is characterized by at least comprising a first corbel brick, a second corbel brick, a third corbel brick, anti-slip modules, refractory brick fire clay and a circular groove, and the first corbel brick and the second corbel brick are on the same layer; the third corbel brick is the upper layer of the first corbel brick and the second corbel brick; circular grooves are pressed in the upper surfaces and the lower surfaces of the first corbel brick, the second corbel brick and the third corbel brick correspondingly, and the upper-layer circular grooves correspond to the lower-layer circular grooves. The anti-sliding modules are placed between the two corresponding grooves, and the space between the corbel bricks and the space between the circular grooves and the anti-sliding modules are filled with refractory brick fire clay. The anti-slip structure of the corbel brick of the dry quenching furnace can simplify the brick type of the corbel part and enhance the strength of the corbel brick body, and is convenient to produce, manufacture and construct.

Description

technical field [0001] The invention relates to a dry quenching coke oven masonry process, in particular to a dry quenching coke oven corbel brick anti-slip structure. Background technique [0002] The CDQ coke oven masonry is divided into cooling section, inclined flue area, ring flue area and pre-storage room from bottom to top. The corbel is located in the inclined flue area, which separates the inclined flue and supports the inner wall of the ring flue. The whole corbel is an inverted triangular structure, which is lifted layer by layer from bottom to top. In order to prevent the bricks from slipping, a tongue-and-groove structure is designed between the layers, and the layers are interlocked to make the corbel structure stable. [0003] The existing tongue-and-groove structure is complex, with C-shaped and D-shaped tongue-and-grooves arranged along the circumferential direction of the furnace body, and D-shaped tongue-and-grooves arranged along the radial direction.

[0003] The existing tongue-and-groove structure is complicated, with C-shaped and D-shaped tongue-and-grooves arranged along the furnace body circumferential direction, and D-shaped tongue-and-grooves arranged along the radial direction

The refractory bricks decomposed by the existing structure have complex shapes and various sizes, especially after the height of the corbels of large CDQ ovens increases, the number of brick types also increases greatly. There are hundreds of bricks in the corbels, resulting in the production of refractory bricks. A large number of molds are required, the production cost is high, the production cycle is long, and the size is easy to make mistakes, which has caused great difficulties in design and production.

At the same time, the C-shaped and D-shaped tongue-groove that penetrate the brick body will cause the stress concentration of the refractory brick in the tongue-groove part. Insufficient strength of refractory bricks
