Radiation type building brick combination door neck brick and building method thereof

Abstract

The invention relates to the field of heat engineering kiln firebrick building and discloses a radiation type building brick combination door neck brick comprising a first brick and a second brick, wherein the first brick and the second brick can be mutually bonded; the first brick comprises a surface A and a surface B; when the surface B and the first brick are built, an angle between radiation lines of an annular building surface is smaller than a self-lock frictional angle of the first brick; the second brick comprises a surface C and a surface D; when the surface C and the first brick arebuilt, an angle between the radiation lines of the annular building surface is smaller than a self-lock frictional angle of the second brick; the surface B of the first brick is mutually bonded with the surface C of the second brick; and the surface A of the first brick and the surface D of the second brick are respectively bonded with the adjacent bricks. The invention also provides a building method of the combination door neck brick, and the combination door neck brick is adopted to combine each ring, By changing the shape of the combination door neck brick and the building construction method, the locking strength of the brick rings and the integral structural performance of a kiln lining are increased; when bricks of both sides are not destroyed, a combination door is locked by neck bricks, and the quality of the brick and the integral building construction is ensured.

Description

technical field [0001] The invention relates to the field of refractory brick masonry for thermal kilns in iron and steel metallurgy, building materials, nonferrous metallurgy and other industries. Background technique [0002] The radial brickwork of thermal kilns is generally not directly built with straight bricks, but with single wedge-shaped brick ring bricks, or a mixture of wedge-shaped bricks and straight bricks, or two Double wedge-shaped brick ring bricks of wedge-shaped bricks. The mixed brick ring of wedge-shaped brick and straight brick and double wedge-shaped brick ring have the advantages of wide range of applicable diameters, flexible and convenient masonry, and easy standardization of brick shapes, etc., and have been affirmed and widely used. There are three types of radial brick rings: straight ring radial brick ring, cone radial brick ring and turning radial brick ring. [0003] Before the present invention proposes, the radial shape masonry door brick ...

AI Technical Summary

Problems solved by technology

[0005] 1. The shape and size of the door bricks processed on site are difficult to meet the requirements of use

It often happens that the size of the brick shape is too large and requires prying and knocking to force the brick ring to close, or the size is too small, resulting in excessive gaps in the brick body, loose brick rings, brick falling and other quality accidents.

[0006] 2. The lining brick ring is prone to triangular seams and affects the quality of use

The size of the large end of the closing door brick is appropriate and the size of the small end is small

The size of the small end is suitable and the size of the large end is too small. The triangular seam appears in the middle of the furnace lining. During the use process and later, bricks are prone to fall off, collapse, and high-temperature liquid or gas is prone to leakage and penetration accidents.

[0007] 3. The overall structural performance of brick ring and furnace lining is difficult to guarantee

When using cut and processed bricks to close the door, only the brick rings are closed and it is difficult to ensure that the brick rings are locked. It is difficult to guarantee the overall structural strength of the furnace lining with many brick rings, which affects the service life.
