Abstract
Description
Technical Field
[0001] This utility model relates to the field of refractory brick technology, and in particular to a high-temperature refractory brick with thermal stability. Background Technology
[0002] Current refractory brick technology has certain limitations. Many traditional refractory bricks lack sufficient high-temperature resistance and oxidation resistance, making them prone to performance degradation in high-temperature environments and unable to effectively resist the effects of extreme temperature changes. Under extremely high temperature conditions, traditional refractory bricks often cannot maintain their structural stability and may experience problems such as cracking, deformation, or thermal expansion, thereby affecting their service life and safety. In addition, many refractory bricks cannot effectively protect the internal structure of the brick from the direct impact of high temperatures. Because the internal materials cannot resist the erosion of high-temperature heat sources, the brick may suffer internal damage after long-term use, leading to structural failure. Utility Model Content
[0003] The purpose of this invention is to address the shortcomings of existing technologies. Current refractory brick technology has certain limitations. Many traditional refractory bricks lack sufficient high-temperature resistance and oxidation resistance, making them prone to performance degradation in high-temperature environments and unable to effectively resist the effects of extreme temperature changes. Under extremely high temperature conditions, traditional refractory bricks often cannot maintain their structural stability and may experience problems such as cracking, deformation, or thermal expansion, thereby affecting their service life and safety. In addition, many refractory bricks cannot effectively protect the internal structure of the brick from the direct impact of high temperatures. Because the internal materials cannot resist the erosion of high-temperature heat sources, the brick may suffer internal damage after long-term use, leading to structural failure. This invention provides a high-temperature refractory brick with thermal stability.
[0004] To achieve the above objectives, this utility model adopts the following technical solution: a thermally stable high-temperature refractory brick, comprising a main body structure, the main body structure including a protective layer, an insulation layer disposed inside the protective layer, a connecting layer disposed on the inner wall of the insulation layer, a protective coating disposed on the outer surface of the protective layer, and an embedded insulation mechanism disposed inside the main body structure.
[0005] The structure includes a heat insulation shell, and a support member is provided inside the heat insulation shell. Both sides of the support member are fixedly connected with fixing rings.
[0006] In a preferred embodiment, the protective layer is made of aluminosilicate material, the heat insulation layer is made of expanded ceramic material, and the connecting layer is made of high-alumina brick material.
[0007] In a preferred embodiment, the heat insulation shell is made of the same material as the heat insulation layer and is formed by a thermoplastic molding device, and the support member is made of woven mesh made of alloy steel.
[0008] In a preferred embodiment, the interior of the fabricated heat insulation shell is fitted with a fixing ring with a support member, and aerogel is injected by injection molding. Then, the heat insulation shell is sealed by another support member to complete the embedded heat insulation mechanism.
[0009] In a preferred embodiment, the embedded heat insulation mechanism is used as a base, and a first cylindrical mold is set on the outside of the embedded heat insulation mechanism to form a first compartment. The spacing of the first compartment is set to 1-1.5cm. Then, a mixture of high-alumina brick material is injected into the first compartment, and a connecting layer is formed after solidification.
[0010] In a preferred embodiment, the connecting layer is used as a base, and a second cylindrical mold is set on the outside of the connecting layer to form a second compartment. The spacing of the second compartment is set to 1-1.5cm. Then, an expanded ceramic material mixture is injected into the second compartment, and after solidification, a heat insulation layer is formed.
[0011] In a preferred embodiment, the heat insulation layer is used as a base, and a refractory brick mold is set on the outside of the heat insulation layer to form a third compartment. Then, an aluminosilicate material mixture is injected into the third compartment, and after solidification, a protective layer is formed, and finally the main structure is formed. The outside of the main structure is coated with a protective coating to form refractory bricks.
[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows:
[0013] This invention utilizes an aluminosilicate protective layer that exhibits excellent high-temperature resistance and oxidation resistance, enabling it to withstand extreme temperature changes while protecting the internal structure of the brick from direct high-temperature effects. The internal expanded ceramic material provides excellent thermal insulation, effectively reducing heat conduction, maintaining stable external temperature, and preventing heat leakage, thereby improving the thermal stability of the brick under high-temperature conditions.
[0014] Through the design of the insulation shell and support components, this embedded structure greatly enhances the compressive strength and stability of the refractory bricks. The alloy steel mesh structure of the support components provides additional strength support, ensuring that the bricks are not easily deformed or cracked under high-temperature conditions. The connection through the fixing rings ensures the stability of the insulation shell and support components, preventing the internal structure from loosening due to high temperatures or external forces, further improving the reliability of the bricks. The connecting layer uses high-alumina brick material, which gives it good mechanical strength and wear resistance, enabling it to withstand extremely high temperatures and thermal shock. The protective coating further enhances the surface refractory performance of the bricks, preventing corrosion, oxidation, and high-temperature erosion. Attached Figure Description
