[0003] In view of this, we propose a furnace door structure of step -by -step heating furnace. CONTENT OF UTILITY MODEL
[0004] The present application aims to solve the technical problem that the furnace door of step -by -step heating furnace in the prior art adopts the traditional refractory material or composite heat preservation structure, and the heat preservation performance will decline after long time use under high temperature environment.
[0005] To achieve the above object, the utility model provides the following technical scheme:

[0014] Compared with the prior art, the technical effects and advantages of the utility model are:

[0021] The technical solutions in the embodiments of the utility model will be described clearly and completely below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor belong to the scope of protection of the utility model.
[0022] The following description is made in connection with Figs. 1-2 Further details of the present application are described below,
[0023] The furnace door structure of the step-by-step heating furnace disclosed by the embodiments of the present application comprises:
[0024] The furnace door frame 2 serves as the support structure of the furnace door 1.
[0025] The nanosheet layer 3 is composed of multiple layers of nanomaterials and is tightly bonded inside the furnace door frame 2 by special adhesives to ensure that there are no gaps.
[0026] The sealing structure 4 includes one or more sealing strips or gaskets and is installed in the groove 5 of the furnace door 1 to form a seal when the furnace door 1 is in contact with the furnace body.
[0027] By adding nanosheet materials inside the furnace door 1, the excellent heat insulation performance and low thermal conductivity of the nanosheet materials effectively block the transfer of heat, significantly improving the heat preservation performance of the furnace wall and reducing heat loss. At the same time, the advanced sealing mechanism design further reduces heat leakage, improves heating efficiency and safety, and prolongs the service life of the furnace door 1. In addition, the nanosheet material is more economical in cost while ensuring the heat preservation effect, which is conducive to large-scale popularization and application.
[0028] The multiple layers of nanomaterials in the nanosheet layer 3 have a lower thermal conductivity due to their unique nanoscale structure. This means that they can provide better heat insulation than traditional materials at the same thickness, reducing heat loss. Nanosheet materials generally have good thermal shock resistance and can withstand rapid temperature changes without being easily damaged. This is particularly important for the furnace door 1, which experiences dramatic temperature changes during frequent opening and closing. Nanosheet materials generally have good corrosion resistance and can resist chemical corrosion in high-temperature environments, extending the service life of the furnace door 1. Due to the low thermal conductivity of nanosheet materials, their thickness can be thinner than traditional insulation materials, which helps to reduce the overall weight of the furnace door 1 and reduce structural load.
[0029] The use of nanosheet materials significantly reduces the heat conduction of the furnace door 1, reducing the transfer of heat from the furnace to the outside world, thereby reducing heat loss. The excellent heat insulation performance of nanosheet materials helps to maintain stable furnace temperature, reducing heat replenishment during heating and improving energy efficiency. With more stable furnace temperature, heating efficiency is improved, reducing energy consumption.
[0030] Through the above advantages and design optimization, the application of nanosheet materials can significantly improve the heat preservation performance of the furnace door 1 of the step-by-step heating furnace and achieve energy-saving effects.
[0031] It is crucial to ensure the quality of the adhesion between the nanosheet layer 3 and the door frame 2, the adhesive needs to be able to withstand high temperature environment and maintain stable adhesion performance at high temperature. It is necessary to choose adhesives specially designed for high temperature environment, such as high temperature resistant epoxy resin or ceramic based adhesive. Before adhesion, proper cleaning and roughening treatment of the surface of the door frame 2 can increase the adhesion area and improve the adhesion strength. Remove the oil stains, rust and other contaminants on the surface, ensure the surface is clean and dry. Adopt appropriate adhesion process, such as uniform coating of adhesive, to ensure that there is no air bubble or gap between the nanosheet layer 3 and the door frame 2. During the adhesion process, pressure can be used to fix the nanosheet layer 3 on the frame to avoid displacement.
[0032] During the curing of the adhesive, stable temperature and pressure are maintained to avoid the influence of environmental factors on the curing effect. After the adhesion is completed, strict quality detection is needed. Non-destructive detection methods such as ultrasonic detection can be used to check the adhesion quality to ensure that there is no defect. After the adhesive is completely cured, high temperature test is carried out to simulate the actual use condition, to verify the stability and durability of the adhesion structure at high temperature.
[0033] The door frame 2 is provided with a circulating cooling water pipe 6. A plurality of anchor bricks 7 are arranged on the inner side of the circulating cooling water pipe 6 and inside the door frame 2. Anchor hooks 8 are arranged on the outer side of the circulating cooling water pipe 6, the inner side of the door frame 2 and the outer side of the door frame 2.
[0034] The door frame 2 is cast with a lightweight refractory insulation layer 9 that fills the inner chamber and levels the outer edge of the door frame 2. The groove 5 is formed on the lightweight refractory insulation layer 9.
[0035] The design of the circulating cooling water pipe 6 can form a cooling water circulation inside the door frame 2, effectively absorbing and conducting heat, reducing the temperature of the surface of the door 1, thereby protecting the door 1 from high temperature damage. The arrangement of anchor bricks 7 and anchor hooks 8 provides additional structural support, which helps to maintain the integrity of the door frame 2, especially in high temperature environment. These anchorages can prevent the deformation of the door 1 material due to thermal expansion. The casting of the lightweight refractory insulation layer 9 fills the inner chamber of the door frame 2, which helps to improve the insulation effect of the door 1, reduce heat loss, and thus improve the stability and efficiency of the furnace temperature. The leveling treatment of the outer edge of the lightweight refractory insulation layer 9 helps to optimize the heat distribution, reduce the thermal gradient and prevent local overheating, thereby improving the uniformity of the heat treatment process. Due to the protection of the circulating cooling water pipe 6 and the lightweight refractory insulation layer 9, the thermal impact and thermal stress on the material of the door frame 2 are reduced, which helps to prolong the service life of the door 1. By reducing the temperature of the surface of the door 1, the risk of heat injury to the operator is reduced, and the safety of the working environment is improved.
[0036] The nano plate layer 3 is composed of multiple layers of nanometer material, has extremely low thermal conductivity, can effectively block the transfer of heat, and is tightly bonded inside the door frame 2 through a special adhesive, ensuring that no gaps exist and further reducing heat leakage. The sealing strip or gasket in the sealing structure 4 is installed in the groove 5 of the door 1 and can tightly adhere to the furnace body when the door 1 is closed, forming a good sealing effect. This prevents heat from escaping through the gap between the door 1 and the furnace body, improving the overall thermal efficiency. Due to the improved insulation performance and sealing effect, the heat loss in the furnace is greatly reduced, thereby reducing energy consumption during the heating process. In the long run, this will reduce the operating costs of the enterprise, improve energy utilization efficiency, and good insulation and sealing performance help maintain the stability of the temperature in the furnace, which is crucial for heat treatment processes and can ensure product quality and consistency. The use of nano plate material and special adhesive improves the high-temperature resistance and thermal shock resistance of the door 1, reducing material fatigue and damage caused by temperature changes. The selection and installation of the sealing strip or gasket also consider high-temperature resistance and corrosion resistance, which helps to extend the overall service life of the door 1, reduce heat leakage, reduce heat radiation in the working environment, and improve the safety of operators. At the same time, reducing heat loss helps maintain the working environment in the workshop and improves working conditions.
[0037] In summary, the door 1 structure of the step-by-step heating furnace achieves high energy efficiency, improved temperature stability, and safety through innovative design and material selection.
[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present application and is not intended to limit the present application.
