Abstract
The utility model discloses a kind of exchangeable lightweight furnace roof bricks, cuboid brick body, stainless steel and the stainless steel bolt bonded including 2 block-shaped identical mirror images, the adhesive surface of brick body is equipped with trapezoidal conduit, counterbore is equipped in conduit, the stainless steel bottom is equipped with through-hole, stainless steel is contained between conduit, and stainless steel bolt is each passed through the counterbore of 2 pieces of brick bodies, the through-hole of stainless steel fixes 2 pieces of brick bodies and stainless steel.The utility model thermal shock resistance is good with heat-proof quality, and service life is long, is conveniently replaceable.
Description
Technical field
The utility model belongs to Industrial Stoves renovation technique field, and in particular to a kind of exchangeable lightweight furnace roof brick.
Background technology
Furnace roof is one of Industrial Stoves significant points, and service life length often decides the service life of kiln.Mesh
Before, the top construction of kiln is varied, and wherein furred ceiling is most commonly seen one kind.In this top construction, due to furnace roof
The suspended roof brick spelling group hung on girder steel by polylith forms, therefore furnace roof is unlikely to deform, it is not easy to collapse, while the weight of suspended roof brick
Amount will not act on furnace wall, smaller to the material limitation of furnace roof and furnace wall.The same suspended roof brick of tradition mostly uses heavy high intensity
Refractory brick, such as high-alumina brick, clay brick etc., although intensity is preferable, its heat-proof quality is very poor, causes suspended block close to furnace shell
One section of the temperature that the temperature of one end is significantly less than flame contact causes as a result, generating great thermal stress among brick
Suspended roof brick is broken；
Meanwhile suspended roof brick inevitably will appear fracture in the environment of rapid heat cycle.With using thermal shock resistance
The phenomenon that good light heat-insulating material, suspended roof brick is broken on a large scale, is not common, but part sensitive part occurs on a small quantity
Fracture is inevitable, currently without good treating method, because would generally be glued with refractory mortar between suspended roof brick
Knot, avoids leaving gap, so can not be replaced to the suspended roof brick of the fracture of monolithic, greatly shorten kiln uses the longevity
Life.
Invention content
Goal of the invention：The purpose of this utility model is that in view of the deficiencies of the prior art, providing a kind of exchangeable lightweight
Furnace roof brick.
Technical solution：In order to reach foregoing invention purpose, what the utility model was specifically performed by：It is a kind of replaceable
Type lightweight furnace roof brick includes cuboid brick body, stainless steel and the stainless steel bolt of 2 block-shaped identical mirror images bondings, described
The adhesive surface of brick body is equipped with trapezoidal conduit, and counterbore is equipped in conduit, and the stainless steel bottom is equipped with through-hole, and stainless steel is hung
Part is contained between conduit, stainless steel bolt be each passed through the counterbore of 2 pieces of brick bodies, stainless steel through-hole by 2 pieces of brick bodies with
Stainless steel is fixed.
Wherein, the preferred light fire brick of brick body, bulk density≤1.0g/cm3, thermal coefficient≤0.4W/
（m.K）.
Wherein, it is bonded by refractory mortar between brick body, which can bear 1600 DEG C of high temperature, and thick
Degree control is for 1 ~ 2mm.
Further, above-mentioned refractory mortar can also be filled between the stainless steel and brick body.
For the ease of the suspended roof brick of removable parts damage, the side of brick body non-adhering side offers T-slot hole, adjacent
Brick body non-adhering side between adjacent slot is inserted into I-shaped sealed inserted piece by way of to replace traditional use fire resisting
The mode that clay bonds is fixed, and gap can add one layer of cellucotton between adjacent brick body, to improve heat-proof quality.
Wherein, in order to increase the hanging performance of stainless steel, the top of the stainless steel can be equipped with hanging hole.
Wherein, in order to ensure the gap between stainless steel and brick body is as small as possible, the stainless steel shape is
It is trapezoidal, mutually fitted with brick body channel shape.
Advantageous effect：The utility model is compared with traditional technology, and thermal shock resistance is good with heat-proof quality, and service life is long,
It is conveniently replaceable.
