Description

A kind of anticracking refractory brick

Technical field

This utility model is related to technical field of refractory materials, has good mechanical toughness anti-with good more particularly, to a kind of The anticracking refractory brick of thermal shock performance.

Background technology

In traditional sense, refractory material refers to that refractoriness is not less than 1580 DEG C of Inorganic Non-metallic Materials, and it is for height The basic material of temperature technique service, is used as the structural material of the Thermal Equipments such as high temperature kiln, and industrial high temperature container and portion The material of part, and corresponding physicochemical change and mechanism can be born.

It is a problem of generally existing in inorganic non-metallic and material that the mechanical tenacity of Inorganic Non-metallic Materials is poor, is made To belong to the refractory brick of Inorganic Non-metallic Materials together, its mechanical tenacity is also poor, and it is high that its poor mechanical tenacity has also had influence on it Thermal shock resistance when warm, in rapid heat cycle and the gap for using because larger temperature difference refractory brick is easily in the work that expands with heat and contract with cold With the lower situation that the impact refractory brick integrity such as ftracture, peel off occur, the service life of refractory brick is reduced.

The content of the invention

Goal of the invention of the present utility model is in order to overcome the mechanical tenacity of refractory brick of the prior art poor, when high temperature Thermal shock resistance it is poor, rapid heat cycle and the gap that uses are because larger temperature difference refractory brick is easily issued in the effect of expanding with heat and contract with cold A kind of deficiency of raw cracking, there is provided anticracking refractory brick with good mechanical toughness and good thermal shock resistance energy.

To achieve these goals, this utility model is employed the following technical solutions：

A kind of anticracking refractory brick, including brick body and the suspension hook located at brick body upper surface；Brick body is from up to down wrapped successively Include the first flame retardant coating, first thermal insulation layer, Anti-crack layer, second thermal insulation layer and the second flame retardant coating；Brick body is in rectangular-shape, described The upper and lower side of brick body is respectively equipped with the first groove for using cooperatively and first raised, and the left and right side of brick body is respectively equipped with The second groove for using cooperatively and second raised；The length and width of brick body is equal；First groove and the second groove Shape is identical, and described first is raised identical with the second convex shape；First groove, the second groove, the first projection and second The raised equal semicircular in shape in cross section；It is equipped with the fixture block of some groups of protrusions on first groove and the second groove, described The some groups of draw-in grooves used cooperatively with fixture block are equipped with one projection and the second projection；The Anti-crack layer is provided with multiple vertical leading to Hole；Some metal reinforcings are provided with brick body.

This utility model includes fire resisting toughening layer, thermal insulation layer, the Anti-crack layer with through hole and metal reinforcing, makes refractory brick With good mechanical tenacity and anti-cracking function, two blocks of refractory brick are coordinated by fixture block and draw-in groove, raised and groove fit, are made resistance to Firebrick mutually fits.

Preferably, the suspension hook is 4, the suspension hook is L-shaped, and one end of the suspension hook is vertical with brick body upper surface to be connected Connect, the free end of the suspension hook point to successively the right side, under, it is left, on.

The shape of suspension hook is matched with the working environment installed and used.

Preferably, the through hole is in cylinder.

Preferably, the metal reinforcing is in I shape.

Preferably, first flame retardant coating and the second flame retardant coating include mullite particle layer, aluminium oxide granule granulosa, oxygen Change one layer of zirconium granular layer or magnesium aluminate spinel granular layer or which floor.

Increase the mechanical tenacity and thermal shock resistance of refractory brick.

Therefore, this utility model has the advantages that：With good mechanical toughness and good thermal shock resistance energy.
