Description

A kind of metallurgical furnace kiln high-temperature hot-air pipeline brick

Technical field

The utility model belongs to metallurgical furnace kiln pipe technology field, relates to a kind of metallurgical furnace kiln high-temperature hot-air pipeline brick.

Background technology

Along with the development of metallurgical industry, metallurgical equipment and operative technique are obtained for larger lifting, but in recent years, there is the accidents such as local superheating, shell are rubescent, pipeline string wind, inner lining damage in the hot blast manifold of many hotblast stoves, hot-blast main and bustle pipe, these problems significantly limit the development of high wind-warm syndrome technology.

Hot air duct inside generally builds multiple layer refractory by laying bricks or stones, comprise amorphous refractory, insulating brick, refractory brick etc., traditional pipeline masonry construction comprises box hat, sprayed coating, the first layer insulating brick, second layer insulating brick, refractory brick, usually in process of production, need guarantee that the working temperature of box hat is below 150 DEG C; Use standard square to carry out pipeline when building by laying bricks or stones, pipeline masonry can produce certain displacement because expanding with heat and contract with cold, and the longitudinal brickwork joint of the impact by displacement is uncontrollable, occurs straight joint, makes high temperature and high pressure gas contact thermofin, shortens the work-ing life of hot air duct; Meanwhile, after a period of operation, under gravity, the sedimentation slightly of top brick, pipeline section becomes oval to hot air duct, and add refractory materials high temperature creep, long term operation there will be big area and falls brick phenomenon, has a strong impact on the safe operation of equipment.

Therefore how to prevent pipeline masonry from damaging in the operating mode of High Temperature High Pressure, coming off, pipe overheat, accident such as string wind etc. are the thorny problem of pendulum in face of metallargist, pipeline brick to choose with building by laying bricks or stones be an important factor.

Utility model content

The purpose of this utility model is to provide a kind of metallurgical furnace kiln high-temperature hot-air pipeline brick, solves that refractory brick in existing pipeline masonry construction easily comes off in process of production, the problem causing pipeline to leak out of caving in.

The technical scheme that the utility model adopts is, a kind of metallurgical furnace kiln high-temperature hot-air pipeline brick, comprises brick body, and brick body is made up of the first block and the second block, and the second block is identical with the structure of the first block; Its structure is: upper surface is rectangle, and vertical section is inverted trapezoidal, and surface, left and right is parallelogram, and lower surface is rectangle; The lower surface of the first block and the upper surface of the second block coplanar, two pieces of brick bodies form dislocation in the horizontal direction and connect, and form brick groove at the lower surface of the first block, form brick platform at the upper surface of the second block.

Feature of the present utility model is also,

Brick groove and the brick platform of two pieces of brick bodies can fasten mutually.

Brick well width is 1/3 of brick body lower surface width.

The base in parallelogram face and the angle of hypotenuse are 60 °.

The beneficial effects of the utility model are, have prepared the brick body with parallelogram inclined-plane and faulting of slab ends, and utilize this brick body to carry out pipeline to build by laying bricks or stones, fundamentally solve to use traditional standard fragment of brick to carry out brick body when pipeline is built by laying bricks or stones easily to come off, produce the problem of straight joint; The utility model makes the feature of simple, easy construction, long service life, is applicable to various high wind-warm syndrome pipe lining, is beneficial to and applies.

Embodiment

Below in conjunction with the drawings and specific embodiments, the utility model is described in detail.

The three-dimensional arrangement of a kind of metallurgical furnace kiln high-temperature hot-air of the utility model pipeline brick as shown in Figure 1, comprises brick body, and brick body is made up of the first block 1 and the second block 2, and the second block 2 is identical with the structure of the first block 1; Its structure is: upper surface is rectangle, and vertical section is inverted trapezoidal, and surface, left and right is parallelogram, and lower surface is rectangle; The lower surface of the first block 1 and the upper surface of the second block 2 coplanar, two pieces of brick bodies form dislocation in the horizontal direction and connect, and form brick groove 3 at the lower surface of the first block 1, form brick platform 4, as shown in Figure 2 at the upper surface of the second block 3.

Wherein, the brick groove 3 of two pieces of brick bodies and brick platform 4 can fasten mutually.

Brick groove 3 width is 1/3 of brick body lower surface width.

The base in parallelogram face and the angle of hypotenuse are 60 °, as shown in Figure 3.

Use procedure of the present utility model is, when building circular pipeline by laying bricks or stones, polylith brick body overlaps, first block 1 forms a ring, and the second block 2 forms a ring, and the first block brick groove 3 of any one piece of brick body fastens mutually with the second block brick groove 4 of adjacent bricks body, mutual overlap joint realizes overall interlocking, strengthen globality and the stability of masonry, eliminate the radiation seam circumferentially occurred, avoid high-temperature gas to contact thermal insulation layer;

The utility model polylith brick body is along pipeline longitudinal arrangement, bond mutually in the inclined-plane of the two pieces of brick bodies in front and back, the vertical lap seam that can not produce, even if masonry is when expanding or shrink, brick body also can, at inclined-plane top offset, can ensure not occur straight joint, and refractory brick also can be made axially can to vary with temperature free-extension, to prevent structure thermal stress breakage, effectively reduce and produce the possibility of altering wind along pipeline is longitudinally upper.
