Description

Technical Field

[0001] This utility model relates to the technical field of embedded sealed continuous casting water-cooled ladle cover, specifically an embedded sealed continuous casting water-cooled ladle cover. Background Technology

[0002] With the transformation and upgrading of the steel industry, the proportion of ordinary steel in the steel industry is gradually decreasing, while the proportion of special steel is gradually increasing. Protective casting technology is a fundamental and core technology for special steel. The tundish, as a crucial piece of equipment in continuous casting machines, plays a vital role in storing, diverting, and promoting the flotation of inclusions in molten steel. Its design and manufacturing have a significant impact on the quality of the cast billet. Poor tundish sealing will exacerbate secondary oxidation of the molten steel and reduce its heat preservation effect. Tundish sealing primarily depends on the design of the tundish cover; the contact surface between the cover and the tundish body often suffers from poor sealing due to high-temperature deformation of the cover.

[0003] Therefore, an embedded, sealed continuous casting water-cooled ladle cover is needed to improve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide an embedded, sealed continuous casting water-cooled ladle cover to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] An embedded sealed continuous casting water-cooled tundish cover includes a tundish cover body. A first cooling groove is provided on the front side of the interior of the tundish cover body, and a second cooling groove is provided on the rear side of the interior of the tundish cover body. A placement frame is provided inside the first cooling groove and the second cooling groove. A cooling water pipe is provided inside the placement frame. A limiting plate is provided at the outer end of the placement frame. A snap-fit ​​groove is provided on the inner side of the limiting plate. A fixing component is provided on the left side of the tundish cover body.

[0007] The fixing component includes a fixing base, a connecting block is provided inside the fixing base, a first snap-fit ​​plate is slidably disposed on the front side inside the fixing base, a second snap-fit ​​plate is slidably disposed on the rear side inside the fixing base, a first fixing spring is disposed between the rear end of the first snap-fit ​​plate and the front side of the connecting block, a second fixing spring is disposed between the front end of the second snap-fit ​​plate and the back side of the connecting block, a first adjusting rod is disposed on the left side of the first snap-fit ​​plate, a second adjusting rod is disposed on the left side of the second snap-fit ​​plate, and adjusting grooves are symmetrically opened on the front and rear sides of the left side of the fixing base.

[0011] As a preferred embodiment of this utility model, the adjustment grooves are respectively adapted to the first adjustment rod and the second adjustment rod.

[0012] As a preferred embodiment of this utility model, the cooling water pipe is arranged in a serpentine structure.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] In this invention, by setting cooling water pipes and fixing components on the embedded sealed continuous casting water-cooled tundish cover, the internal temperature of the tundish cover body can be cooled through the cooling water pipes, thereby preventing the tundish cover body from deforming due to high temperature. Furthermore, pressing the first and second adjusting rods inward can drive the first and second snap-fit ​​plates to move to the outside of the snap-fit ​​groove, thereby pulling the limiting plate outward can pull out the placement frame.

[0025] For examples, please refer to Figure 1-5 This utility model provides a technical solution:

[0026] An embedded sealed continuous casting water-cooled tundish cover includes a tundish cover body 1. A first cooling groove 2 is provided on the front side of the interior of the tundish cover body 1, and a second cooling groove 3 is provided on the rear side of the interior of the tundish cover body 1. A placement frame 4 is provided inside both the first cooling groove 2 and the second cooling groove 3. A cooling water pipe 5 is provided inside the placement frame 4. A limiting plate 6 is provided at the outer end of the placement frame 4. A snap-fit ​​groove 7 is provided on the inner side of the limiting plate 6. A fixing component 8 is provided on the left side of the tundish cover body 1.

[0027] In this embodiment, please refer to Figure 4 and 5The fixing component 8 includes a fixing base 801, a connecting block 802 is provided inside the fixing base 801, a first locking plate 803 is slidably provided on the front side inside the fixing base 801, a second locking plate 804 is slidably provided on the rear side inside the fixing base 801, a first fixing spring 805 is provided between the rear end of the first locking plate 803 and the front side of the connecting block 802, a second fixing spring 806 is provided between the front end of the second locking plate 804 and the back side of the connecting block 802, a first adjusting rod 807 is provided on the left side of the first locking plate 803, a second adjusting rod 808 is provided on the left side of the second locking plate 804, and adjusting grooves 809 are symmetrically opened on the front and rear sides of the left side of the fixing base 801.

[0028] The placement frame 4 is adapted to the first cooling groove 2 and the second cooling groove 3 respectively. The right side of the fixing seat 801 is fixedly connected to the tundish cover body 1. The first snap-fit ​​plate 803 and the second snap-fit ​​plate 804 are respectively adapted to the snap-fit ​​groove 7. The adjustment groove 809 is respectively adapted to the first adjustment rod 807 and the second adjustment rod 808. The cooling water pipe 5 is arranged in a serpentine structure. By setting the cooling water pipe 5 and the fixing component 8 on the embedded sealed continuous casting water-cooled tundish cover, the tundish cover body can be adjusted through the cooling water pipe 5. The internal cooling of the device prevents deformation of the inner cover body 1 due to high temperature. The inward pressing of the first adjusting rod 807 and the second adjusting rod 808 can move the first snap-fit ​​plate 803 and the second snap-fit ​​plate 804 to the outside of the snap-fit ​​groove 7. The limiting plate 6 can then be pulled outward to remove the placement frame 4. When the cooling water pipe 5 is damaged, it can be easily replaced, thus improving the cooling performance and sealing of the inner cover body 1. The overall device has a simple structure, is easy to operate, and is more practical.

[0029] The working process of this utility model is as follows: When using the embedded sealed continuous casting water-cooled tundish cover, the interior of the tundish cover body 1 can be cooled through the cooling water pipe 5, thereby preventing the tundish cover body 1 from deforming due to high temperature. When the cooling water pipe 5 is damaged, the first adjusting rod 807 and the second adjusting rod 808 are pressed inward. When the first adjusting rod 807 and the second adjusting rod 808 move inward, they respectively drive the first locking plate 803 and the second locking plate 804 to move. When the first locking plate 803 and the second locking plate 804 move to the outside of the locking groove 7, they move outward. Pulling the side limit plate 6 can pull out the placement frame 4, allowing the cooling water pipe 5 inside the placement frame 4 to be replaced, thus improving its cooling performance and the sealing of the inner cover body 1. During installation, the placement frame 4 is inserted into the first cooling groove 2 and the second cooling groove 3 respectively. Loosening the first adjusting rod 807 and the second adjusting rod 808, under the force of the first fixing spring 805 and the second fixing spring 806, drives the first snap-fit ​​plate 803 and the second snap-fit ​​plate 804 into the snap-fit ​​groove 7 respectively, thus installing it. Installation and disassembly are relatively convenient.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
