Description

Technical Field

[0001] The utility model belongs to the technical field of tundishes, and particularly relates to a corrosion-resistant and long-life impact plate. Background Technique

[0002] A tundish is a refractory container used in short-process steelmaking. First, it receives the molten steel poured from a ladle, and then distributes it to each mold through the tundish nozzle. The impact plate is an important component of the tundish and is used to withstand the impact of molten steel. The performance of the impact plate directly affects the service safety and service life of the tundish.

[0003] Currently, most of the existing impact plates are of an integral structure. The impact plate relies on its own material properties to resist the impact of molten steel. After being subjected to the impact of molten steel for a long time, the service life is shortened relatively quickly. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a corrosion-resistant and long-life impact plate to solve the problems raised in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical scheme: A corrosion-resistant and long-life impact plate, including a bottom plate and a top plate. Support columns are installed around the bottom plate, and the top plate is slidably sleeved on the support columns around it. The upper end of the support column is threadedly sleeved with a limit nut, and the limit nut abuts against the top surface of the top plate.

[0006] A number of high-temperature resistant rubber blocks are arranged inside the bottom plate. The high-temperature resistant rubber blocks are evenly distributed inside the bottom plate, and the upper ends of the high-temperature resistant rubber blocks abut against the bottom surface of the top plate.

[0007] As a preferred embodiment, the top plate includes a clay main body, a heat insulation layer and a corrosion-resistant coating. The heat insulation layer is fixedly connected to the surface of the clay main body, and the corrosion-resistant coating is coated on the surface of the heat insulation layer.

[0008] As a preferred embodiment, a number of protrusions are arranged on the top surface of the top plate.

[0009] As a preferred embodiment, deformation holes are formed inside the high-temperature resistant rubber blocks.

[0010] As a preferred embodiment, a buffer pad is fixedly connected to the top surface of the bottom plate.

[0011] As a preferred embodiment, accommodation grooves are formed inside the bottom plate around its perimeter, and the lower ends of the support columns extend into the accommodation grooves.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] When in use, place the top plate on the bottom plate, sleeving the top plate on the support column and screwing the limit nut onto the upper end of the support column to make the top plate press against the high-temperature resistant rubber block. When the top plate is impacted by molten steel, the top plate will forcefully squeeze the high-temperature resistant rubber block, causing the high-temperature resistant rubber block to deform and buffer and reduce the impact force received by the top plate, thereby improving the impact resistance of the top plate and extending the service life of the impact plate.

[0014] For this corrosion-resistant and long-life impact plate, through the setting of the heat insulation layer, the heat insulation effect of the top plate can be improved. Through the setting of the corrosion-resistant coating, the corrosion resistance of the impact plate can be improved, further extending the service life. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] The following further describes the present utility model in conjunction with embodiments.

[0020] The following embodiments are used to illustrate the present utility model, but cannot be used to limit the protection scope of the present utility model. The conditions in the embodiments can be further adjusted according to specific conditions. Any simple improvement to the method of the present utility model under the premise of the concept of the present utility model belongs to the protection scope required by the present utility model.

[0021] Please refer to Figures 1-3 , the present utility model provides a corrosion-resistant and long-life impact plate, including a bottom plate 1 and a top plate 2. The bottom plate 1 is made of clay, and the top plate 2 includes a clay main body 21, a heat insulation layer 22 and a corrosion-resistant coating 23. The heat insulation layer 22 is made of asbestos, and the heat insulation layer 22 is fixedly connected to the surface of the clay main body 21. Through the setting of the heat insulation layer 22, the heat insulation effect of the top plate 2 can be improved. The corrosion-resistant coating 23 is a corrosion-resistant paint, and the corrosion-resistant coating 23 is coated on the surface of the heat insulation layer 22. Through the setting of the corrosion-resistant coating 23, the corrosion resistance of the impact plate can be improved, further extending the service life.

[0022] Refer to Figure 1 and Figure 2, support columns 11 are installed around the bottom plate 1. The top plate 2 is slidably sleeved on the support columns 11 around its perimeter. A limit nut 12 is threadedly sleeved on the upper end of the support column 11, and the limit nut 12 abuts against the top surface of the top plate 2. Inside the bottom plate 1, a number of high-temperature resistant rubber blocks 13 are provided. The several high-temperature resistant rubber blocks 13 are evenly distributed within the bottom plate 1, and the upper ends of the high-temperature resistant rubber blocks 13 abut against the bottom surface of the top plate 2. Deformation holes 14 are formed inside the high-temperature resistant rubber blocks 13. During use, place the top plate 2 on the bottom plate 1, so that the top plate 2 is sleeved on the support columns 11, and sleeve the limit nut 12 on the upper end of the support column 11 and tighten it, so that the top plate 2 presses against the high-temperature resistant rubber blocks 13. When the top plate 2 is impacted by molten steel, the top plate 2 will forcefully squeeze the high-temperature resistant rubber blocks 13, causing the high-temperature resistant rubber blocks 13 to deform and buffer and reduce the impact force received by the top plate 2, thereby improving the impact resistance of the top plate 2 and extending the service life of the impact plate; in addition, after the top plate 2 has been used for a long time, the limit nut 12 can be removed to disassemble and replace the top plate 2.

[0023] Further, a number of protrusions 24 are provided on the top surface of the top plate 2. Through the arrangement of the protrusions 24, when the molten steel impacts the top plate 2, the protrusions 24 can disperse and offset the impact force of the molten steel, reducing the impact on the top plate 2.

[0024] To avoid violent collision between the top plate 2 and the bottom plate 1, a buffer pad 15 is fixedly connected to the top surface of the bottom plate 1. When the top plate 2 moves under impact, it will ultimately collide with the buffer pad 15, reducing the impact between the bottom plate 1 and the top plate 2.

[0025] Further, accommodation grooves 16 are formed inside the four sides of the bottom plate 1. The lower ends of the support columns 11 extend into the accommodation grooves 16. When the top plate 2 is impacted, the support columns 11 can move into the accommodation grooves 16, preventing the support columns 11 from being damaged due to excessive force.

[0026] The working principle and usage process of the present utility model: First, during use, place the top plate 2 on the bottom plate 1, so that the top plate 2 is sleeved on the support columns 11, and sleeve the limit nut 12 on the upper end of the support column 11 and tighten it, so that the top plate 2 presses against the high-temperature resistant rubber blocks 13. When the top plate 2 is impacted by molten steel, the protrusions 24 can disperse and offset the impact force of the molten steel, reducing the impact on the top plate 2. At the same time, the top plate 2 will forcefully squeeze the high-temperature resistant rubber blocks 13, causing the high-temperature resistant rubber blocks 13 to deform and buffer and reduce the impact force received by the top plate 2, thereby improving the impact resistance of the top plate 2 and extending the service life of the impact plate; in addition, after the top plate 2 has been used for a long time, the limit nut 12 can be removed to disassemble and replace the top plate 2; through the arrangement of the corrosion-resistant coating 23, the corrosion resistance of the impact plate can be improved, further extending its service life.

[0027] Although embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
