Description
TECHNICAL FIELD
[0001] The present disclosure relates to the technical field of furnace nose system sealing in the production process of cold rolling system hot dip aluminum silicon, in particular to a new sealing device for the production process of aluminum silicon plating. BACKGROUND
[0002] The furnace nose system is used for producing aluminum silicon plated plates, please refer to Figure 1 The furnace nose system includes the most front end furnace nose head immersion section (or referred to as A section 10), the intermediate chute section (or referred to as B section 20), and the furnace zone outlet expansion joint section (or referred to as C section). The A section needs to withstand not only the strong solution corrosion but also the high temperature baking of aluminum liquid due to long-term immersion in the high temperature aluminum silicon solution. After multiple frequent online use and offline maintenance, the flange and other structures of the A section will have obvious thermal deformation. The main deformation is located at the flange of the A section, which presents a "convex" shape after deformation, that is, the middle of the flange length direction protrudes upward, the two sides are downward, and the height difference between the middle and the two sides is 5mm, which is the maximum process allowed deformation. If the value exceeds the value, offline maintenance treatment is required, and the flange surface is reprocessed to a flat state for reuse.
[0003] Specifically, the outer periphery of the flange of the A section and the flange of the B section is usually sealed by a graphite packing and then fastened and installed by bolts to ensure that the gas flowing between the flanges of the A section and the B section will not leak from the outer periphery. However, when the deformation of the flange of the A section exceeds 5mm, the deformation of the graphite packing is not enough to ensure good sealing between the flanges of the A section and the B section, resulting in leakage of the gas flowing between the flanges of the A section and the B section, and thus the flange of the A section needs to be reprocessed. CONTENT OF THE UTILITY MODEL
[0004] In order to overcome the poor sealing effect of the sealing device between the flanges of the A section and the B section, the utility model provides a new sealing device for the production process of aluminum silicon plating.
[0005] In order to achieve the above purpose, the present disclosure provides a new sealing device for the production process of aluminum silicon plating, which comprises:
[0006] A copper alloy sheet is bent into multiple sections from the upper end to the lower end; and
[0007] A high-temperature-resistant fiber plate is provided with a relief groove and a mounting hole, the relief groove is used for avoiding the center through hole of the flange of the A section and the flange of the B section, and the mounting hole is used for penetrating the connecting bolt between the flange of the A section and the flange of the B section, the number of the high-temperature-resistant fiber plates is multiple, and each is arranged between the adjacent two horizontal sections of the bent copper alloy sheet, and the copper alloy sheet and the multiple high-temperature-resistant fiber plates are press-fitted and connected.
[0008] Optionally, the copper alloy sheet is bent into a W shape, the number of the high-temperature-resistant fiber plates is three, and the high-temperature-resistant fiber plates are arranged between the W shapes.
[0009] Optionally, the thickness of the copper alloy sheet before bending is 1.2-1.8 mm.
[0010] Optionally, the thickness of the sealing device is 20-25 mm.
[0011] Optionally, one end of the high-temperature-resistant fiber plate is configured as a curved surface, and the curved surface is matched with the bent section of the copper alloy sheet.
[0012] The technical scheme provided by the embodiment of the present disclosure can include the following beneficial effects:
[0013] The copper alloy has good high-temperature resistance (physical melting point is 1083℃), good flexibility, and the like. When the flange of the A section (furnace nose head flange) is convex, the copper alloy sheet is deformed according to the bending amount of the flange of the A section. The high-temperature-resistant fiber plate filled in the copper alloy sheet after bending has a gas tightness close to 0 after compression, so as to avoid the overflow of gas between the flanges of the A section and the B section. After the copper alloy sheet is bent by the process, the copper alloy sheet can not only increase the compensation amount of the device, but also has an important use, that is, the bent part of the copper alloy is used to complete the sealing of the upper and lower flanges. The sealing characteristic is to use the flexibility of the copper alloy. When the flanges of the A section and the B section are fastened, the copper alloy sheet can complete a large amount of shape change. When the copper alloy sheet is deformed, the copper alloy sheet can be tightly attached between the flanges of the A section and the B section, so as to prevent the overflow of gas between the flanges of the A section and the B section.

[0020] The specific embodiments of the present disclosure are described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are merely intended to illustrate and explain the present disclosure, and are not intended to limit the present disclosure.
[0021] In the present disclosure, the orientation words such as "up, down, front, back, left, right" are used for the convenience of description, which are defined according to the direction of the drawing surface of the corresponding drawing, and "inner, outer" are defined according to the contour of the corresponding part itself. The terms such as "first, second" used in the present disclosure are used to distinguish one element from another element, and do not have sequentiality and importance. In addition, when the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated.
[0022] Please refer to Figures 2 to 4 The present disclosure provides a new sealing device 40 for the production process of aluminized silicon, which comprises a copper alloy sheet 41 and a high-temperature-resistant fiber plate 42. The copper alloy sheet 41 is bent into multiple sections from the upper end to the lower end. The high-temperature-resistant fiber plate 42 and the copper alloy sheet 41 are both provided with avoidance grooves 4112 and mounting holes 4111. The avoidance grooves 4112 are used to avoid the center through holes of the A section flange 11 and the B section flange 21, and the mounting holes 4111 are used to penetrate the connecting bolts between the A section flange 11 and the B section flange 21. The number of high-temperature-resistant fiber plates 42 is multiple, and each is arranged between two adjacent horizontal sections 411 of the bent copper alloy sheet 41. The copper alloy sheet 41 and the multiple high-temperature-resistant fiber plates 42 are connected by press fitting.
[0023] It can be understood that the copper alloy has good high-temperature resistance (physical melting point of 1083℃), good flexibility and easy bending processing and other advantages. When the convex type of the A-section flange 11 (furnace nose head flange) appears, the copper alloy sheet 41 will be deformed according to the bending amount of the A-section flange 11. After the copper alloy sheet 41 is bent, the copper alloy sheet 41 is pressed with the high-temperature resistant fiber plate 42, and the air tightness of the high-temperature resistant fiber plate 42 after pressing is close to 0, avoiding the overflow of gas between the A-section flange 11 and the B-section flange 21. After the copper alloy sheet 41 is bent by the process, in addition to increasing the compensation amount of the device, there is an important use, that is, using the bending part of the copper alloy to complete the sealing of the upper and lower flanges. This sealing characteristic uses the flexibility of the copper alloy. When the A-section flange 11 and the B-section flange 21 are fastened, the copper alloy sheet 41 can complete a large amount of shape change, and when deformed, the copper alloy sheet 41 can be tightly attached between the A-section flange 11 and the B-section flange 21, ensuring that the gas between the A-section flange 11 and the B-section flange 21 does not overflow, thereby avoiding the need to reprocess the A-section flange 11, which is more cost-effective.
[0024] In an embodiment, please refer to Figure 3 , the copper alloy sheet 41 is bent into a W shape, that is, the bent copper alloy sheet 41 includes two horizontal sections 411 and three bending sections 412. Bending the copper alloy sheet 41 three times can increase the bending compensation amount of the copper alloy sheet 41. The number of high-temperature resistant fiber plates 42 is three, and each is arranged between the W shapes. The high-temperature resistant limiting plate is used to fill the space between the adjacent horizontal sections 411 of the bent A-section flange 11, avoiding the overflow of gas.
[0025] In an embodiment, the thickness of the copper alloy sheet 41 before bending is 1.2mm-1.8mm. For example, the thickness of the copper alloy sheet 41 before bending can be 1.2mm, 1.5mm or 1.8mm. If the thickness of the copper alloy sheet 41 is too thick, the copper alloy sheet 41 will not be easy to bend; if the thickness of the copper alloy sheet 41 is too thin, the structural strength of the copper alloy sheet 41 will be low, and plastic deformation and fracture will be prone to occur.
[0026] In an embodiment, the thickness of the sealing device 40 is 20mm-25mm, which can compensate for a maximum of 9mm of the deformation amount of the A-section flange 11 according to the design size.
[0027] In an embodiment, please refer to Figure 3 , one end of the high-temperature resistant fiber plate 42 is configured as an arc surface, which is matched with the bending section of the copper alloy sheet 41 to ensure good adhesion and avoid gas overflow.
[0028] The present application is described by way of examples, and it is to be understood that various alterations and / or equivalents can be apparent to those skilled in the art without departing from the spirit and scope of the present application. In addition, it is to be understood that the features and embodiments described herein can be modified to adapt to specific situations and materials without departing from the spirit and scope of the present application. Therefore, the present application is not limited to the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of the present application are to be included in the scope of the present application.
