Description

A kind of high tenacity refractory brick

Technical field

This utility model is related to technical field of refractory materials, especially relates to one kind and has good mechanical toughness and well resist The high tenacity 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 to be a problem of generally existing in inorganic non-metallic and material that the mechanical tenacity of Inorganic Non-metallic Materials is poor, makees For belonging 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 the gap of rapid heat cycle and use because larger temperature difference refractory brick is easily in the work that expands with heat and contract with cold With the situation of the lower impact refractory brick integrity such as ftracture, peel off, reduce the service life of refractory brick.

Content of the invention

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

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

A kind of high tenacity refractory brick, the suspension hook including brick body with located at brick body upper surface；Brick body is from up to down successively Including the first flame retardant coating, the first Anti-crack layer, thermal insulation layer, the second Anti-crack layer and the second flame retardant coating；Brick body is in rectangular-shaped, institute The upper and lower side stating brick body is respectively equipped with the first groove using cooperatively and the first projection, and the left and right side of brick body sets respectively There are the second groove using cooperatively and the second projection；The cross section of described first groove and the first projection is all rectangular；Described The equal semicircular in shape in cross section of two grooves and the second projection；Described first Anti-crack layer and the second Anti-crack layer are equipped with multiple vertical Through hole.

This utility model includes fire resisting toughening layer, thermal insulation layer and the Anti-crack layer with through hole, so that refractory brick is had good Mechanical tenacity and anti-cracking function, two blocks of refractory brick pass through fixture block and draw-in groove cooperation, raised and groove fit, so that refractory brick is mutually affixed Close.

Preferably, described through hole is in cone.

Preferably, described metal reinforcing is in I shape.

Preferably, described first flame retardant coating and the second flame retardant coating all include mullite particle layer, alumina fiber layer, oxygen Change one layer of zirconium fibrous layer or magnesium aluminate spinel granular layer or which floor.

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

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

Brief description

Fig. 1 is a kind of front view of the present utility model；

Fig. 2 is a kind of top view of the present utility model；

Fig. 3 is a kind of profile of the present utility model.

In figure：Brick body 1, suspension hook 2, the first flame retardant coating 11, the first Anti-crack layer 12, thermal insulation layer 13, the second Anti-crack layer 14, second Flame retardant coating 15, the first groove 31, the first projection 32, the second groove 33, the second projection 34, through hole 131.

Specific embodiment

With reference to the accompanying drawings and detailed description this utility model is further described.

As shown in Figure 1, Figure 2, the embodiment of Fig. 3 is a kind of high tenacity refractory brick, including brick body 1 and hanging located at brick body upper surface Hook 2；Brick body from up to down includes the first flame retardant coating 11, the first Anti-crack layer 12, thermal insulation layer 13, the second Anti-crack layer 14 He successively Second flame retardant coating 15；Brick body is in rectangular-shaped, and the upper and lower side of brick body is respectively equipped with the first groove using cooperatively 31 and first projection 32, the left and right side of brick body is respectively equipped with the second groove 33 using cooperatively and the second projection 34；Institute State the first groove and the cross section of the first projection is all rectangular；The cross section of described second groove and the second projection is all in semicircle Shape；Described first Anti-crack layer and the second Anti-crack layer are equipped with multiple vertical through holes 131；Described suspension hook is 4, and described suspension hook is in L-type, one end of described suspension hook is vertical with brick body upper surface to be connected, the free end of described suspension hook point to successively the right side, under, left, on；Institute Stating through hole is in cone；Described first flame retardant coating and the second flame retardant coating all include mullite particle layer, alumina fiber layer, oxidation One layer of zirconium fibrous layer or magnesium aluminate spinel granular layer or which floor.

This utility model includes fire resisting toughening layer, thermal insulation layer and the Anti-crack layer with through hole, and fire resisting toughening layer is by mullite One layer of granular layer, alumina fiber layer, Zirconium oxide fibre layer or magnesium aluminate spinel granular layer or which floor composition, make refractory brick have There are good mechanical tenacity and anti-cracking function, two blocks of refractory brick pass through raised and groove fit, so that refractory brick is mutually fitted.

Therefore, this utility model has the characteristics that good mechanical toughness and good thermal shock resistance can.
