Description

Technical Field

[0001] This utility model belongs to the field of furnace body technology, specifically relating to a novel furnace body with heat preservation function. Background Technology

[0002] In metal smelting, high-temperature furnaces are used to heat the metal, causing the solid metal to reach its melting point and liquefy into liquid metal for subsequent metal parts manufacturing. The furnace body has strict requirements for high-temperature resistance and heat preservation. Currently, the heat preservation efficiency of the furnace body is low, and heat is easily dissipated into the air, causing high temperatures to affect the external environment. At the same time, in order to meet the temperature requirements inside the furnace body, a large amount of fuel is required to heat the furnace body, resulting in high metal processing costs.

[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only for explaining the present utility model and are not intended to limit the present utility model; that is, the described embodiments are only some embodiments of the present utility model, and not all embodiments. The components of the embodiments of the present utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0019] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0020] The following is combined with Figure 1This invention describes a novel furnace body with heat preservation function. The furnace body has an internal hollow structure. From the inside to the outside, the furnace body is provided with a contact layer 1, a heat preservation layer 2, and a reinforcing layer 3. The contact layer 1, the heat preservation layer 2, and the reinforcing layer 3 are sequentially nested to form an integrated structure. Because the internal temperature of the furnace body is high, the contact layer 1 is made of magnesia-chrome brick with high refractoriness. The heat preservation layer 2 can keep the internal temperature of the furnace body warm. The reinforcing layer 3 is a steel structure layer, which can improve the overall strength of the furnace body.

[0021] Advantageously, the insulation layer 2 comprises, from the inside out, a heat insulation layer 21, an expansion layer 22, and a heat reflective layer 23. The heat insulation layer 21 and the contact layer 1 are fitted together to form a thermal expansion structure. Since the expansion layer 22 is sandwiched between the heat insulation layer 21 and the heat reflective layer 23, and due to the thermal expansion of the magnesia-chrome brick layer 11 and the heat insulation layer 21, the expansion layer 22 can have a certain degree of contraction. The heat reflective layer 23 and the reinforcing layer 3 are fitted together to form a support structure. The expansion layer 22 connects the thermal expansion structure and the support structure, and the support structure is located on one side of the expansion layer 22, thereby improving the overall support of the furnace body. In the furnace body, by dividing the furnace body into the contact layer 1, the insulation layer 2, and the reinforcing layer 3, and by dividing the insulation layer 2 into the heat insulation layer 21, the expansion layer 22, and the heat reflective layer 23, the magnesia-chrome brick layer 11, due to its internal contact with high-temperature molten copper, has strong refractory properties, thus protecting the furnace body from high-temperature effects. The heat insulation layer 21 uses ordinary refractory bricks to insulate the interior of the furnace. The expansion layer 22 uses high-polymer heat insulation cotton that can absorb heat as the heat insulation layer 2, so that the heat inside and outside the furnace is isolated by the expansion layer 22, thus achieving heat insulation of the interior of the furnace. The heat reflective layer 23 is coated on the expansion layer 22. The heat reflective layer 23 can reflect the heat transmitted from the interior of the furnace, thus insulating the interior of the furnace. Using the heat reflective layer 23 as a barrier layer, when the melting temperature reaches 1200℃ without the addition of the heat high barrier layer, the temperature of the steel structure layer is 120℃±10℃. After adding the heat high barrier layer, when the melting temperature reaches 1200℃, the temperature of the steel structure layer drops to 70℃±5℃. The temperature reduction of the furnace steel structure layer protects the external environment from the high temperature of the furnace. The high-polymer heat insulation cotton can be high-temperature asbestos or high-polymer fiber cotton, which can block the transfer of heat and can deform.

[0022] Advantageously, the heat insulation layer 21 is made of refractory bricks. The temperature decreases from the inside to the outside of the furnace body. Since the temperature inside the furnace body is relatively high, the heat insulation layer 21 still retains a certain temperature when the temperature is transferred to it. The refractory bricks can be protected from the effects of high temperature and the service life of the furnace body can be improved.

[0023] Advantageously, the refractory brick is one or more of corundum brick, dolomite brick, or mullite brick.

[0024] Advantageously, the expansion layer 22 is made of high-polymer heat insulation cotton, which can keep the heat inside the furnace body warm. At the same time, it can shrink after the magnesium chrome brick layer 11 and the heat insulation layer 21 expand under high temperature. While serving as the heat insulation layer 2, the expansion layer 22 also acts as a shrinkage joint to adapt to the deformation of the furnace body after being heated.

[0025] Advantageously, the thickness of the expansion layer 22 is less than half the thickness of the heat insulation layer 21. The lower thickness of the expansion layer 22 avoids affecting the overall strength due to excessive thickness.

[0026] Advantageously, the heat reflective layer 23 includes an organic film layer 231 for increasing the high temperature resistance of the furnace body and a metal layer 232 for reflecting the heat transferred inside the furnace body. The organic film layer 231 serves as the base layer of the heat reflective layer 23, and at the same time, the high temperature resistance of its material is used to improve the high temperature resistance of the entire furnace body. The metal layer 232 is electroplated on the organic film layer 231 to reflect the heat transferred inside the furnace body.

[0027] Advantageously, the metal layer 232 is a highly reflective metal, electroplated on the organic film layer 231. Utilizing the reflective properties of the metal, the heat transferred inside the furnace is reflected after being transferred to the bright metal surface, thereby improving the heat preservation effect of the furnace. In some embodiments, the metal layer 232 can be any one or more metal elements, as long as it has reflective properties. No special limitation is made here, and all are within the protection scope of this solution. In this example, the metal layer 232 is preferably one or more of aluminum, nickel, and chromium. Aluminum, nickel, and chromium metal elements have good reflective effects and low cost.

[0028] Advantageously, the reinforcing layer 3 is made of steel, and the outer peripheral surface of the reinforcing layer 3 is coated with a heat-resistant and heat-insulating paint to reduce the temperature of the reinforcing layer 3 to 70℃±5℃.

[0029] Working principle of this utility model:

[0030] The furnace body is constructed from the inside out with the following layers: a magnesia-chrome brick layer 11, a heat insulation layer 21, an expansion layer 22, a heat reflective layer 23, and a reinforcing layer 3. The magnesia-chrome brick layer 11 is made of high-temperature resistant brick. When in direct contact with the molten copper inside the furnace, the magnesia-chrome brick layer 11 is not affected by the high temperature. The internal temperature of the furnace body remains relatively constant after being insulated by the magnesia-chrome brick layer 11. The heat insulation layer 21, made of refractory brick with slightly lower high-temperature resistance than the magnesia-chrome brick layer 11, is then fitted over the magnesia-chrome brick layer 11. The cost of the refractory brick in the heat insulation layer 21 is lower than that of the magnesia-chrome brick layer 11. An expansion layer 22, made of high-polymer heat insulation cotton, is then fitted over the heat insulation layer 21 to a certain extent. The insulation layer provides thermal insulation while also having a certain shrinkage capacity, allowing it to adapt to the deformation of the magnesia-chrome brick layer 11 and the insulation layer 21. The outer layer of the expansion layer 22 is provided with a heat-reflective layer 23, which serves as a high thermal barrier layer. The heat-reflective layer 23 includes an organic film layer 231 as the base layer, and a metal layer 232 electroplated on the organic film layer 231. By utilizing the reflective properties of the metal, the heat inside the furnace is transferred to the bright surface of the metal layer 232 and then reflected, thereby improving the thermal insulation effect inside the furnace. The outermost layer of the furnace body is a steel structure reinforcement layer 3, which can improve the overall strength of the furnace body. By using different insulation materials in different layers, the furnace body can be insulated.
