Abstract
The utility model relates to a heating furnace skirt hem brick which belongs to the technical field of refractory material, and aims at solving the technical problems of providing a heating furnace skirt hem brick which is not easy to deform or fall off and is used in the bottom of a stepping-type heating furnace; and the technical scheme is as follows: a brick body is formed by separated blocks, and the length plane and the width plane of the brick body are provided with long holes penetrating the thickness direction of the brick body. In the heating furnace skirt hem brick adopting the structure, the long hole structure can lead the brick body not easily to deform or fall off, and can maintain enough strength; the long hole structure can also lead the weight of the brick body to be greatly reduced, thus lightening the load born by the bottom of the heating furnace; and the brick body is designed into the separated blocks, thus being more convenient for installation and conveying. The adoption of the skirt hem brick can avoid production accidents caused by the falling-off of the skirt hem bricks, thus reducing overhauling time and improving production rate.
Description
Technical field
The skirt that the utility model relates to a kind of steel rolling walking beam furnace use encloses brick, belongs to technical field of refractory materials.
Background technology
Employed walking beam furnace furnace bottom skirt enclosed refractory brick that brick is common form and builds by laying bricks or stones and form during steel rolling was at present produced.(maintenance insulation) and high temperature (ordinary production) alternately influence the bar heating furnace because low temperature in the production use, make the skirt of building by laying bricks or stones enclose brick and distortion occurred, and the brick body that causes part to build by laying bricks or stones comes off, and drops in the driven beam leghole of refractory brick in the water sealed tank under the furnace bottom, makes dreg pushing board and water sealed tank produce scratching, squeezing bad water sealed tank causes water sealed tank to leak, even the dreg pushing board weld bond collapsed out, cause dreg pushing board to come off, and then the moving beam of asphyxia by external pressure on the chest and abdomen, cause that moving beam is failure to actuate, can only stop production to overhaul.The damage that skirt encloses brick also causes furnace bottom poorly sealed, and furnace bottom returned fire downwards when furnace pressure was high, causes that easily localized hyperthermia damages furnace bottom equipment, causes burnup to increase simultaneously; Furnace bottom sucked temperature in the cold wind reduction stove when furnace pressure was low, produced temperature distributing disproportionation in the stove, brought operation easier for simultaneously the fiery operating personnel of accent.Therefore, how solving skirt, to enclose that brick is easy to generate distortion, comes off be the problem of pendulum in face of the technical staff.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of heating furnace skirt not yielding, that the walking beam furnace furnace bottom of difficult drop-off uses and encloses brick.
The technical scheme that solves the problems of the technologies described above is:
A kind of heating furnace skirt encloses brick, and its brick body is a cuboid, and its improvements are that described brick body is that split block is formed, and the slotted hole that connects brick body thickness direction is arranged on the length and width plane of brick body.
Above-mentioned heating furnace skirt encloses brick, and the shape of described slotted hole is identical with the moving beam column movable span of heating furnace, with leghole 3-5mm measure-alike or bigger than normal.
Above-mentioned heating furnace skirt encloses brick, and the edge of described slotted hole is 115-120mm apart from the edge of brick body.
Above-mentioned heating furnace skirt encloses brick, and the two ends of the long axis direction of described slotted hole are circular-arc.
Above-mentioned heating furnace skirt encloses brick, and described brick body is by forming with 2 split blocks of cuboid center longitudinal axis or central, transverse axis boundary, and the outer surface of brick body is formed in the outside of 2 split blocks, and the inner face of 2 split blocks is formed the slotted hole surface of brick body.
Above-mentioned heating furnace skirt encloses brick, and described brick body is by forming with 4 split blocks of cuboid center longitudinal axis and central, transverse axis boundary, and the outer surface of brick body is formed in the outside of 4 split blocks, and the inner face of 4 split blocks is formed the slotted hole surface of brick body.
Adopt the heating furnace skirt of this structure to enclose brick, the slotted hole structure can not make the brick body yielding and come off, and can keep enough intensity; The more traditional skirt of brick body encloses the brick structure compactness, and quality reduces, and bears a heavy burden at the bottom of having alleviated heating-furnace; The brick body is designed to 4 split blocks, makes installation and transports convenient.Adopt this skirt to enclose brick and can avoid enclosing the production accident that brick comes off and causes, reduced the repair time, improved productivity ratio because of skirt.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Number in the figure is as follows: brick body 1, slotted hole 2, split block 3
The specific embodiment
Show among the figure that this heating furnace skirt encloses brick brick body 1 and is cuboid, its appearance and size and original skirt enclose the appearance and size of brick can be identical, and improved structure is to have a slotted hole 2 on brick body 1.Furnace bottom bears a heavy burden and the maintenance skirt encloses the brick balance in order to alleviate, through measuring and calculating, skirt encloses brick thickness 120mm and gets final product, skirt encloses the size design of the interior hole dimension of brick according to leghole simultaneously, with leghole is measure-alike also can 3-5mm bigger than normal, the edge of therefore designing slotted hole 2 is 115-120mm apart from the edge of brick body 1.In actual fabrication, the length of brick body, and the arc diameter of slotted hole can be according to requiring design in moving beam or the stove.
For the ease of installing and transportation, skirt to be enclosed brick be designed to 2 or 4 split blocks 3, assemble at the scene, gets final product with pug bonding seam.Present embodiment is designed to 4 split blocks.
This heating furnace skirt encloses brick can choose material according to heating furnace actual motion environment, can select high-alumina refractory material or common high temperature resistant clay matter for use, also can select the vacuum cellulosic for use.Bar heating furnace soaking zone temperature is the highest about 1200 ℃, and for saving cost, present embodiment has been selected common high temperature resistant clay matter for use.
