Technical Field
[0001] This utility model relates to the technical field of steel ladles, and more particularly to a steel ladle liner. Background Technology
[0002] A steel ladle (also known as a giant ladle or giant ladle, commonly called a steel bag or large tank) consists of a steel shell, a refractory lining, and an opening and closing control system. Its cross-section is generally circular. It is a container used to transport and pour molten metal. The inside of the steel ladle has a special lining to prevent the molten metal from corroding it.
[0003] Currently, traditional steel ladle liners are often severely damaged when carrying large amounts of high-temperature molten metal, affecting the service life of the ladle. Therefore, workers need to frequently replace or repair the ladle liners, which not only increases production costs but also reduces work efficiency. Utility Model Content
[0004] This utility model aims to at least partially solve one of the technical problems in the above-mentioned technologies.
[0005] Therefore, one objective of this utility model is to provide a steel ladle liner that, by setting up a protective mechanism, has a protective layer placed outside the high-temperature resistant layer. The protective layer is made of high-strength wear-resistant material, which increases the wear resistance and service life of the liner.
[0006] To achieve the above objectives, the first aspect of this utility model provides a steel ladle liner, comprising: an air-cooled forming machine and a moisture-proof mechanism, wherein the moisture-proof mechanism includes a fixed plate, a sealing ring, a rotating shaft, a clamping plate, and a moisture-proof plate, wherein the fixed plate is disposed inside the air-cooled forming machine, the sealing ring is sleeved on the outer wall of the fixed plate, the rotating shaft is disposed on the outer wall of the fixed plate, the clamping plate is pivotally connected to the rotating shaft, and a groove is formed on the inner wall of the fixed plate, wherein the moisture-proof plate is slidably connected inside the groove.
[0007] In addition, the steel ladle liner proposed above according to this utility model may also have the following additional technical features: Specifically, the inner liner is provided with a support assembly, which includes a limiting post and a spring. The limiting post is set on the inner wall of the inner liner, and the spring is sleeved on the outside of the limiting post. The two ends of the spring are respectively connected to the inner wall of the inner liner and the outer wall of the protective roller.
[0008] Specifically, the outer wall of the lining is equipped with embedded pipes.
[0009] Specifically, the embedded pipe is equipped with a sealing assembly, which includes a fixing plate, a sealing ring, a sealing plate, a connecting plate, and a sealing shell. The fixing plate is located inside the embedded pipe, the sealing ring is fitted outside the fixing plate, the sealing plate is located on the outer wall of the fixing plate, the connecting plate is located on the outer wall of the sealing plate, and the sealing shell is located outside the sealing plate.
[0010] Specifically, each of the limit posts is equipped with a corresponding docking post.
[0011] Specifically, reinforcing ribs are provided on the outer wall of the protective roller.
[0012] Compared with existing technologies, this utility model has the following beneficial effects: The ladle liner of this utility model, by setting a protective mechanism, has a protective layer placed outside the high-temperature resistant layer. This protective layer is made of high-strength wear-resistant material, increasing the wear resistance and service life of the liner. Simultaneously, the high-temperature resistant layer effectively prevents the lining from being corroded by high-temperature molten metal, further improving the service life of the ladle liner. By setting a support component inside the liner, with the two ends of a spring connected to the inner wall of the liner and the outer wall of the protective roller respectively, the elastic support of the spring effectively mitigates the impact of molten metal on the liner, further protecting the liner from damage.

[0016] The embodiments of this utility model are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.
[0017] A ladle liner according to an embodiment of the present invention will now be described with reference to the accompanying drawings.
[0018] like Figures 1-5 As shown, a steel ladle liner according to an embodiment of the present invention includes: a liner 1 and a protective mechanism 3.
[0019] The protective mechanism 3 includes a protective roller 31, a protective shell 32, a fire-resistant layer 33, a high-temperature resistant layer 34, and a protective layer 35.
[0020] The protective roller 31 is disposed inside the inner liner 1, the protective shell 32 is disposed outside the protective roller 31, the fire-resistant layer 33 is disposed outside the protective shell 32, the high-temperature resistant layer 34 is disposed outside the fire-resistant layer 33, and the protective layer 35 is disposed outside the high-temperature resistant layer 34.
[0021] It should be noted that the refractory layer 33 described in the utility model embodiment of this application is made of alumina, which can effectively resist the erosion of high-temperature molten metal, thereby extending the service life of the ladle liner 1. The high-temperature resistant layer 34 is made of high-entropy stainless steel, which can withstand temperatures from 1000℃ to over 4000℃. The protective layer 35, as the outermost layer, provides additional protection. The protective layer 35 is made of rubber, which has excellent wear resistance and anti-aging properties, and can further extend the service life of the ladle liner 1.
[0022] In one embodiment of this application, such as Figure 1 As shown, the inner lining 1 is provided with a support component 4, which includes a limiting post 41 and a spring 43.
[0023] The limiting post 41 is set on the inner wall of the liner 1, and the spring 43 is sleeved on the outside of the limiting post 41. The two ends of the spring 43 are respectively connected to the inner wall of the liner 1 and the outer wall of the protective roller 31.
[0024] Each limiting post 41 is provided with a corresponding docking post 42.
[0025] Specifically, when transporting molten metal, the weight of the molten metal will exert pressure on the protective roller 31, causing the protective roller 31 to move towards the inner wall of the inner liner 1. At this time, the spring 43 is compressed. Through the elastic properties of the spring 43, the weight of the molten metal is buffered, preventing the protective roller 31 from being directly subjected to excessive impact force and thus being damaged. The setting of the docking post 42 can facilitate the installation and disassembly of the limiting post 41, thereby facilitating the maintenance and replacement of the support component 4.
[0026] In one embodiment of this application, such as Figure 1 As shown, the outer wall of the inner lining 1 is provided with a pre-embedded pipe 2.
[0027] Understandably, by setting up the pre-embedded pipe 2, when the ladle liner 1 needs to be repaired or replaced, the staff can quickly and conveniently repair or replace the ladle liner 1 through the pre-embedded pipe 2 without disassembling the entire ladle, which greatly improves the efficiency of repair or replacement and reduces production costs.
[0028] In one embodiment of this application, such as Figure 5 As shown, a sealing assembly 5 is provided inside the pre-embedded pipe 2. The sealing assembly 5 includes a fixing plate 51, a sealing ring 52, a sealing plate 53, a connecting plate 54, and a sealing shell 55. The fixing plate 51 is located inside the pre-embedded pipe 2, the sealing ring 52 is sleeved on the outside of the fixing plate 51, the sealing plate 53 is located on the outer wall of the fixing plate 51, the connecting plate 54 is located on the outer wall of the sealing plate 53, and the sealing shell 55 is located on the outside of the sealing plate 53.
[0029] Specifically, when the embedded pipe 2 is used, the sealing component 5 seals the opening of the embedded pipe 2 to prevent molten metal or other impurities from leaking out, thus improving the sealing performance of the ladle liner 1. The fixing plate 51 is used to fix the entire sealing component 5, ensuring its stability. The sealing ring 52 further improves the sealing performance of the embedded pipe 2, preventing molten metal leakage. The sealing plate 53, connecting plate 54, and sealing shell 55 together form a complete sealing structure, providing comprehensive sealing to the opening of the embedded pipe 2. Furthermore, the sealing shell 55 also protects the sealing ring 52 and sealing plate 53, extending the service life of the sealing component 5.
[0030] In one embodiment of this application, such as Figure 2 As shown, reinforcing ribs 6 are provided on the outer wall of the protective roller 31.
[0031] Understandably, the addition of reinforcing ribs 6 can increase the structural strength of the protective roller 31 and improve its load-bearing capacity, enabling the protective roller 31 to better resist the weight and pressure of molten metal, thereby further extending the service life of the ladle liner 1.
[0032] Working Principle: In use, the ladle liner 1 is first installed inside the steel drum. Molten metal is poured into the drum, and the weight of the molten metal exerts pressure on the protective roller 31, causing it to move towards the inner wall of the liner 1. At this time, the spring 43 is compressed, and its elasticity buffers the weight of the molten metal, preventing the protective roller 31 from being damaged by excessive impact. Simultaneously, the refractory layer 33, the high-temperature resistant layer 34, and the protective layer 35 effectively resist the erosion of the high-temperature molten metal, thereby extending the service life of the ladle liner 1. When maintenance or replacement of the ladle liner 1 is required, workers can quickly and conveniently perform the maintenance or replacement through the pre-embedded pipe 2 without disassembling the entire ladle, greatly improving the efficiency of maintenance or replacement and reducing production costs.
