Description

Technical Field

[0001] This utility model relates to the field of heating furnace technology, specifically to a fiber furnace roof and furnace wall overlapping structure. Background Technology

[0002] The heating furnace is a core thermal equipment in the steel rolling production line of the iron and steel industry. It is specifically used to heat steel billets (square billets, slabs, flat billets, etc.) to a uniform and suitable high-temperature state for plastic deformation before rolling (usually between 1100°C and 1300°C). Its performance directly determines the stability of the rolling process, the quality of the rolled product, energy consumption, and output. Heating furnaces have relatively high requirements for high-temperature resistance and heat preservation; poor heat preservation will result in a large amount of heat loss.

[0003] The current furnace wall is a concrete structure, with the furnace roof overlapping the upper part of the furnace wall. After long-term use, gaps are prone to appear at the joint between the furnace wall and the furnace roof due to the high temperature environment, resulting in heat loss and increased heating costs. Utility Model Content

[0005] To achieve the above objectives, the present invention provides the following technical solution: a fiber furnace top and furnace wall overlapping structure, including furnace walls on both sides of the furnace body, with a fiber furnace top overlapping the upper end of the furnace wall, a sealing mechanism for preventing the diffusion of high-temperature gas inside the furnace provided at the overlapping part of the fiber furnace top and the furnace wall, and a protective component for limiting the fiber furnace top provided at the upper end of the furnace wall outside the fiber furnace top.

[0006] Preferably, the sealing mechanism includes a fiber layer, which is laid at the overlap between the top of the fiber furnace and the furnace wall.

[0007] Preferably, the fiber layer is composed of several layers of fiber cloth.

[0008] Preferably, the sealing mechanism includes a foam layer, which is formed by injecting foam adhesive into the joint between the furnace wall and the fiber furnace roof.

[0011] Preferably, the height of the concrete block is the same as the height of the fiber module in the fiber furnace top.

[0012] Preferably, a protective plate is provided on the outer wall of the furnace wall, and the upper end of the protective plate extends to the upper end of the concrete.

[0013] Preferably, the fiber furnace top is formed by splicing together several fiber insulation units.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. The fiber furnace roof and furnace wall overlap structure has a sealing mechanism at the overlap part to prevent the diffusion of high-temperature gas inside the furnace. The overlap part of the fiber furnace roof and furnace wall has good sealing performance, which can effectively reduce the loss of heat inside the furnace body. At the same time, it can prevent heat from spreading from the overlap part of the furnace wall and furnace roof, prevent the upper part of the furnace wall from being damaged under long-term high temperature conditions, and improve the service life of the furnace wall.

[0031] Example

[0032] Please see Figure 1-3As shown, this utility model provides a fiber furnace roof and furnace wall overlap structure, including furnace walls 1 on both sides of the furnace body's feed inlet and discharge outlet. A fiber furnace roof 2 overlaps the upper end of the furnace wall 1. The width of the overlap between the fiber furnace roof 2 and the furnace wall 1 is greater than half the width of the upper surface of the furnace wall 1. The fiber furnace roof 2 is formed by splicing several fiber insulation units, forming the furnace roof in a modular manner, making the installation and maintenance of the furnace roof simpler and more convenient. A sealing mechanism is provided at the overlap part of the fiber furnace roof 2 and the furnace wall 1 to prevent the diffusion of high-temperature gas inside the furnace. The sealing mechanism includes a fiber layer 3, which is laid at the overlap part of the fiber furnace roof 2 and the furnace wall 1. The fiber layer 3 is made of several layers of fiber cloth. The fiber layer 3 is in a "I" shape between the fiber furnace roof 2 and the furnace wall 1, which can increase the sealing effect of the overlap part of the furnace wall 1 and the fiber furnace roof 2. The sealing mechanism is sprayed with heat-insulating coating on one side inside the furnace, that is, the heat-insulating coating is applied to the side of the fiber layer 3 inside the furnace, improving the high temperature resistance and heat insulation effect.

[0033] See Figure 4-5 In other embodiments, the sealing mechanism includes a foam layer 4, which is formed by injecting foam adhesive into the splice between the furnace wall 1 and the fiber furnace roof 2. The sealing mechanism is coated with heat-insulating coating on one side inside the furnace, that is, the heat-insulating coating is applied to the side of the foam layer 4 inside the furnace to improve the high temperature resistance and heat insulation effect.

[0034] The upper end of the furnace wall 1 is located on the outside of the fiber furnace top 2 and is equipped with a protective component to limit the fiber furnace top 2. The protective component includes a concrete block 5. The concrete block 5 is poured on the upper end of the furnace wall 1 on the outside of the fiber furnace top 2. The height of the concrete block 5 is the same as the height of the fiber module in the fiber furnace top 2. It can effectively limit the two sides of the fiber furnace top 2 and improve the heat preservation effect. A protective plate 6 is installed on the outer wall of the furnace wall 1 to prevent the outer side of the furnace top and the outer side of the concrete block 5 from falling off, reducing safety hazards. The upper end of the protective plate 6 extends to the upper end of the concrete.

[0035] In this embodiment, when overlapping the fiber furnace roof 2, the fiber layer 3 is first laid on the furnace wall 1, and then several fiber insulation units are overlapped on the upper end of the furnace wall 1 to form the fiber furnace roof 2. After the fiber furnace roof 2 is fixed, concrete blocks 5 are poured to complete the construction of the fiber furnace roof 2. The overlap between the fiber furnace roof 2 and the furnace wall 1 has good sealing performance, which can effectively reduce the loss of heat inside the furnace body. At the same time, it can prevent heat from spreading from the overlap between the furnace wall 1 and the fiber furnace roof 2, prevent the upper end of the furnace wall 1 from being damaged under high temperature conditions for a long time, and improve the service life of the furnace wall 1.

[0036] Example 2

[0037] Please see Figure 6-7As shown, the present invention provides a fiber furnace top and furnace wall overlap structure. Based on embodiment 1, the fiber layer 3 sealing mechanism includes a fiber layer 3, which is laid at the overlap of the fiber furnace top 2 and the furnace wall 1. The fiber layer 3 is made of several layers of fiber cloth. The fiber layer 3 is inverted "L" shape between the fiber furnace top 2 and the furnace wall 1. By increasing the sealing area through the inverted "L" shape, the sealing effect of the overlap between the furnace wall 1 and the fiber furnace top 2 can be increased. The sealing mechanism is sprayed with heat-insulating coating on one side inside the furnace, that is, the heat-insulating coating is applied to the side of the fiber layer 3 inside the furnace, which improves the high temperature resistance and heat insulation effect.

[0038] Example 3

[0039] Please see Figure 8-9 As shown, the present invention provides a fiber furnace top and furnace wall overlap structure. Based on embodiment 1, the fiber layer 3 sealing mechanism includes a fiber layer 3, which is laid at the overlap of the fiber furnace top 2 and the furnace wall 1. The fiber layer 3 is made of several layers of fiber cloth and is a "Z" shape rotated 90°. The "Z" shape structure further increases the sealing area, which can increase the sealing effect of the overlap between the furnace wall 1 and the fiber furnace top 2. The sealing mechanism is sprayed with heat-insulating coating on one side inside the furnace, that is, the heat-insulating coating is applied to the side of the fiber layer 3 inside the furnace, which improves the high temperature resistance and heat insulation effect.
