Description

Technical Field

[0001] The utility model relates to the technical field of refractory bricks, in particular to a refractory brick with good anti-deformation effect. Background Art

[0002] Refractory bricks are a type of building material with high-temperature resistance. Refractory bricks are widely used in many industrial fields. In the steel industry, they are used to build the lining of high-temperature equipment such as blast furnaces and hot blast furnaces to withstand high temperatures, slag erosion and thermal shock. In the glass manufacturing industry, they are used to build kilns to ensure the normal operation of the kilns at high temperatures. Refractory bricks also play an important role in non-ferrous metal smelting.

[0003] However, the prior art still has the following problems:

[0004] First, the refractory bricks of the prior art are not easy to be firmly spliced. The two ends of the brick body may lack an effective connection design, resulting in the connection of multiple refractory bricks not being tight enough when spliced ​​and used, and unable to form a stable whole. It is difficult to effectively disperse external forces and thermal stresses, which easily causes deformation of individual bricks and poor stability of the overall structure.

[0005] Secondly, most of the refractory bricks in the existing technology are made of a single material, resulting in performance that needs to be improved. Refractory bricks may use a single material or a simple combination, which cannot fully utilize the advantages of different materials, resulting in insufficient strength and stability of the refractory bricks, weak thermal shock resistance, poor deformation resistance, easy damage in harsh environments, short service life, and poor stability.

[0006] In response to the above problems, the inventors proposed a refractory brick with good anti-deformation effect to solve the above problems. Utility Model Content

[0007] In order to solve the problem that it is difficult to carry out firm splicing and the single material leads to the problem that the performance needs to be improved; the purpose of the utility model is to provide a refractory brick with good anti-deformation effect.

A plurality of arc grooves are provided at both ends of the brick body, and a plurality of square grooves are provided at both ends of the brick body, and the arc grooves and square grooves on one side are alternately distributed at equal intervals. Two positioning plates are fixedly provided at the upper end of the brick body, and two plate grooves for cooperating with the positioning plates are provided at the lower end of the brick body. Three positioning columns distributed at equal intervals are fixedly provided at the upper end of the brick body, and three column grooves for cooperating with the positioning columns are provided at the lower end of the brick body. Two clips are fixed on both sides of one end of the brick body, and clip grooves for cooperating with the clip strips are provided on both sides of the other end of the brick body. The cross-section of the clip strip is an isosceles trapezoid, and when the two brick bodies are spliced, the outer surface of the clip strip fits with the inner wall of the corresponding clip groove.

[0009] Preferably, a cavity is opened on the inner wall of the brick body, and the outer surface of the filling body is fixedly connected to the inner wall of the cavity. The filling body is composed of a composite of multiple layers of materials. The filling body includes a base plate, and both ends of the base plate are fixedly provided with a reinforcement layer. The specific material of the base plate is a high-aluminum material, and the specific material of the reinforcement layer is a mullite material. The outer ends of the two reinforcement layers are fixedly provided with a heat-conducting layer, and the outer ends of the two heat-conducting layers are respectively fixedly connected to the inner walls on both sides of the cavity. The specific material of the heat-conducting layer is an aluminum titanate plate, and the specific material of the brick body is a silicon carbide plate. Specifically, the positioning structure and the card strip on the outer surface of the brick body are both silicon carbide plates.

[0010] Compared with the prior art, the beneficial effects of the present invention are:

[0011] 1. The utility model uses the arc grooves and square grooves alternately distributed at both ends of the brick body, as well as the mutually coordinated positioning plates and plate grooves, positioning columns and column grooves, clamping strips and clamping grooves, etc., so that multiple refractory bricks can be tightly connected when spliced ​​and used to form a stable whole, effectively dispersing external forces and thermal stresses, reducing the deformation of individual bricks, and enhancing the stability of the overall structure;

[0012] 2. The utility model improves the strength and stability of refractory bricks and enhances the overall thermal shock resistance by adopting a filling body composed of multiple layers of materials. The combined use can significantly enhance the deformation resistance of refractory bricks and greatly improve the service life and stability of refractory bricks in harsh environments.

The brick body 1 is the main body of the refractory brick. The high-temperature resistant alloy rib 3 running through the inside of the brick body 1 improves the overall strength and rigidity of the refractory brick, and can effectively resist deformation caused by external force and thermal stress. The arc grooves 11 and square grooves 12 alternately distributed at both ends of the brick body 1 can better adapt to temperature changes and thermal expansion, and reduce the risk of deformation.

[0021] Example 2: Figure 3 As shown, the inner wall of the brick body 1 is provided with a cavity 17, and the outer surface of the filling body 2 is fixedly connected to the inner wall of the cavity 17. The filling body 2 is composed of a multi-layer material composite. The filling body 2 includes a base plate 23.

The arc grooves 11 and square grooves 12 alternately distributed at both ends of the brick body 1 better adapt to temperature changes and thermal expansion, reducing the risk of deformation.

[0023] The coordinated positioning plate 15 and plate groove 16, positioning column 13 and column groove 14, clamping strip 4 and clamping groove 41 enable multiple refractory bricks to be tightly connected when spliced ​​and used, forming a stable overall structure, jointly sharing external force and thermal stress, and reducing the deformation of individual refractory bricks;
