Background

With the gradual extension of the service life of the glass kiln, the hook bricks of different degrees turn around at the later stage of a plurality of kilns, which influences the service life of the glass kiln. The reason is deeply found because the concave surface part of the hook brick is directly contacted with the supporting iron of the steel structure, and the heat conducting property of the steel structure metal material is good, so that the bottom of the hook brick is cooled quickly, stress cracks are generated, the head of the hook brick in the kiln falls off, the kiln is damaged, and the service life is shortened.

The utility model adopts the following technical scheme: fused zirconia corundum composite hook brick, including the whole brick body that is the cuboid shape, brick body left side is equipped with the hook portion of a body structure, and hook portion left surface flushes with brick body left surface, and brick body rear side is equipped with the isolated part of a body structure on hook portion right side, and isolated part trailing flank, hook portion trailing flank flush with brick body trailing flank, and brick body upper surface is at the fixed aluminium oxide heat preservation that is equipped with of hook portion right side, isolated part front side.

The length of the brick body and the hook part along the front-back direction is 300-600mm, the width of the brick body along the left-right direction is 350-600mm, and the thickness of the brick body is 150-200 mm.

The left side and the rear side of the aluminum oxide heat-insulating layer are respectively contacted with the right side of the hook part and the front side of the isolation part, the front side and the right side of the aluminum oxide heat-insulating layer are respectively flush with the front side and the right side of the brick body, and the thickness of the aluminum oxide heat-insulating layer is 30-50 mm.

The width of the hook part is 100-200mm, and the thickness of the hook part is 60-100 mm.

The width of the isolation part is 50-100mm, and the thickness of the isolation part is equal to that of the alumina heat-insulating layer.

By adopting the technical scheme, the aluminum oxide heat-insulating layer is arranged, and the iron support at the lower end of the steel structure is in contact with the aluminum oxide heat-insulating layer, so that heat can be reduced and transferred to the iron support from the brick body, and the problem that the local cooling of the hook brick is too fast is solved. During construction, a plurality of hook bricks are sequentially butted along the front and the back, the front and the back of the hook parts are also sequentially connected, and the two adjacent aluminum oxide heat-insulating layers are separated by the separating parts. The structural sizes of all parts of the hook brick are designed according to the construction requirements of the glass kiln. The brick body and the alumina heat-insulating layer are manufactured separately, and finally the alumina heat-insulating layer is bonded on the upper surface of the brick body.

Detailed Description

As shown in fig. 1 and 2, the fused zirconia-corundum composite hook brick of the utility model comprises a brick body 1 which is integrally cuboid-shaped, a hook part 2 which is of an integral structure is arranged on the left side of the brick body 1, the left side surface of the hook part 2 is flush with the left side surface of the brick body 1, an isolation part 3 which is of an integral structure is arranged on the right side of the hook part 2 on the rear side of the brick body 1, the rear side surface of the isolation part 3 and the rear side surface of the hook part 2 are flush with the rear side surface of the brick body 1, and an alumina heat insulation layer 4 is fixedly arranged on the right side of the hook part 2 and the front side of the isolation part 3 on the upper surface of the brick body 1.

The length of the brick body 1 and the hook part 2 along the front-back direction is 300-600mm, the width of the brick body 1 along the left-right direction is 350-600mm, and the thickness of the brick body 1 is 150-200 mm.

The left side and the rear side of the aluminum oxide heat-insulating layer 4 are respectively contacted with the right side of the hook part 2 and the front side of the isolation part 3, the front side and the right side of the aluminum oxide heat-insulating layer 4 are respectively flush with the front side and the right side of the brick body 1, and the thickness of the aluminum oxide heat-insulating layer 4 is 30-50 mm.

The width of the hook part 2 is 100-200mm, and the thickness of the hook part 2 is 60-100 mm.

The width of the isolation part 3 is 50-100mm, and the thickness of the isolation part 3 is equal to that of the alumina heat-insulating layer 4.

Because the aluminum oxide heat-insulating layer 4 is arranged, the iron support at the lower end of the steel structure is in contact with the aluminum oxide heat-insulating layer 4, the heat can be reduced and transferred to the iron support from the brick body 1, and the problem that the local cooling of the hook brick is too fast is solved. During construction, a plurality of hook bricks are sequentially butted along the front and the back, the hook parts 2 are also sequentially connected in the front and the back, and the isolation parts 3 isolate two adjacent aluminum oxide heat-insulating layers 4, as shown in figures 3 and 4.
