Description

Technical Field

[0001] This utility model relates to the field of metallurgical technology, and in particular to a sliding plate structure for a molten steel ladle that can be precisely positioned and installed. Background Technology

[0002] The ladle sliding gate mechanism consists of a base, support, slider, disc spring assembly, and drive assembly. The mechanism is separated by upper and lower sliding plates. The base and support are fixed parts, while the slider is the movable part. The upper gate brick and upper sliding plate brick are fixed within the base, while the lower sliding plate brick and lower gate brick are fixed within the slider, which can reciprocate within the support. A constant and uniform interface pressure is established at the movable interface through the disc spring assembly. The power source drives the slider to reciprocate through the drive assembly, thereby achieving throttling of the molten steel.

[0003] The upper and lower sliding plates of a molten steel ladle have highly similar structures on their front and back sides, but the working and non-working surfaces are made of different materials. The upper sliding plate, because its non-working surface needs to be coated with fire putty, is easy to distinguish and less likely to be installed backwards. However, the lower sliding plate is very easy to install backwards during installation, leading to contact between the working and non-working surfaces during operation, poor sealing at the contact surface, and steel leakage, resulting in steel leakage accidents. Therefore, this utility model proposes a precisely positioned sliding plate structure for a molten steel ladle to overcome the shortcomings of the existing technology. Utility Model Content

[0004] To address the aforementioned problems, the purpose of this utility model is to provide a steel ladle sliding plate structure that can be precisely positioned and installed. When the lower sliding plate body is installed backwards, the second limiting block is resisted by the first limiting block, preventing the lower sliding plate body from being installed into the lower mold frame. This avoids the problem of reverse installation and can effectively improve the installation accuracy of the upper and lower sliding plates.

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

[0006] A precisely positioned and installed steel ladle slide plate structure includes an upper mold frame, an upper slide plate body, a lower mold frame, and a lower slide plate body. The upper mold frame contains a first positioning component, and the upper slide plate body is positioned and installed inside the upper mold frame via the first positioning component. The lower mold frame contains a second positioning component, and the lower slide plate body is positioned and installed inside the lower mold frame via the second positioning component. A first limiting block is provided on one side of the lower mold frame, and an adjustment groove is provided on the side wall of the lower slide plate body away from the first limiting block. A second limiting block is detachably installed in the adjustment groove. After the lower slide plate body is installed inside the lower mold frame, the first limiting block and the second limiting block are symmetrically arranged, and the tops of the first limiting block and the second limiting block are flush.

[0007] A further improvement is that the first positioning component includes a first upper arc edge positioning block and a first lower arc edge positioning block. The first upper arc edge positioning block is symmetrically arranged inside the upper mold frame, and the first lower arc edge positioning block is arranged inside the lower part of the upper mold frame.

[0008] A further improvement is that the second positioning component includes a second upper arc edge positioning block and a second lower arc edge positioning block. The second upper arc edge positioning block is symmetrically arranged inside the upper part of the lower mold frame, and the second lower arc edge positioning block is arranged inside the lower part of the lower mold frame.

[0009] A further improvement is that both the first limiting block and the second limiting block are cylindrical structures, and an adjusting block is slidably provided in the adjusting groove, with the adjusting block connected to the side wall of the second limiting block.

[0010] A further improvement is that: the adjusting block is provided with a locking bolt, the adjusting groove is provided with a locking hole, and there are multiple locking holes. The adjusting block is connected to the locking hole through the locking bolt.

[0011] A further improvement is that: the upper mold frame is symmetrically provided with straight and curved edge positioning blocks for the upper sliding plate, and the lower mold frame is symmetrically provided with straight and curved edge positioning blocks for the lower sliding plate.

[0012] The beneficial effects of this utility model are as follows: By setting a first limiting block inside one side of the lower mold frame and setting an adjustment groove on the side wall of the lower slide body away from the first limiting block, and detachably installing a second limiting block in the adjustment groove, when the lower slide body is installed backwards, the second limiting block is resisted by the first limiting block, so that the lower slide body cannot be installed into the lower mold frame, thereby avoiding the problem of reverse installation and effectively improving the installation accuracy of the upper and lower slides.

[0016] To deepen the understanding of this utility model, the following detailed description will be provided in conjunction with embodiments. These embodiments are only used to explain this utility model and do not constitute a limitation on the scope of protection of this utility model.

[0017] according to Figure 1-2 As shown, this embodiment proposes a steel ladle slide plate structure that can be precisely positioned and installed, including an upper mold frame 1, an upper slide plate body 2, a lower mold frame 3, and a lower slide plate body 4. The upper mold frame 1 is provided with a first positioning component, and the upper slide plate body 2 is positioned and installed inside the upper mold frame 1 through the first positioning component. The lower mold frame 3 is provided with a second positioning component, and the lower slide plate body 4 is positioned and installed inside the lower mold frame 3 through the second positioning component. A first limiting block 5 is provided on one side inside the lower mold frame 3, and an adjustment groove 6 is provided on the side wall of the lower slide plate body 4 away from the first limiting block 5. A second limiting block 7 is detachably installed in the adjustment groove 6. After the lower slide plate body 4 is installed inside the lower mold frame 3, the first limiting block 5 and the second limiting block 7 are symmetrically arranged, and the top of the first limiting block 5 is flush with the top of the second limiting block 7.

[0018] During assembly and operation of the precisely positioned steel ladle sliding plate structure of this utility model, the second limiting block 7 can be adjusted and installed according to the position of the first limiting block 5 inside the lower mold frame 3. This ensures that after the lower sliding plate body 4 is installed inside the lower mold frame 3, the first limiting block 5 and the second limiting block 7 are symmetrically arranged. When the lower sliding plate body 4 is correctly installed inside the lower mold frame 3, the first limiting block 5 is located on the left side inside the lower mold frame 3, while the second limiting block 7 on the side wall of the lower sliding plate body 4 is located on the right side inside the lower mold frame 3. They do not interfere with each other, allowing the lower sliding plate body 4 to be smoothly installed inside the lower mold frame 3. When the lower sliding plate body 4 is installed backwards, the second limiting block 7 will abut against the first limiting block 5, preventing the lower sliding plate body 4 from being locked into the lower mold frame 3 and positioned by the second positioning component. This alerts the operator that the lower sliding plate body 4 is installed backwards and needs to be adjusted and reinstalled.

[0019] The first positioning component includes a first upper arc-edge positioning block 8 and a first lower arc-edge positioning block 9. The first upper arc-edge positioning block 8 is symmetrically arranged inside the upper mold frame 1 at the top, and the first lower arc-edge positioning block 9 is arranged inside the lower part of the upper mold frame 1. The first upper arc-edge positioning block 8 and the first lower arc-edge positioning block 9 cooperate to achieve positioning and installation of the upper slide plate body 2.

[0020] The second positioning component includes a second upper arc-edge positioning block 10 and a second lower arc-edge positioning block 11. The second upper arc-edge positioning block 10 is symmetrically arranged inside the upper part of the lower mold frame 3, and the second lower arc-edge positioning block 11 is arranged inside the lower part of the lower mold frame 3. The second upper arc-edge positioning block 10 and the second lower arc-edge positioning block 11 cooperate to achieve positioning and installation of the lower slide plate body 4.

[0021] Both the first limiting block 5 and the second limiting block 7 are cylindrical structures. An adjusting block 12 is slidably disposed within the adjusting groove 6, and the adjusting block 12 is connected to the side wall of the second limiting block 7. The adjusting block 12 is provided with a locking bolt 13, and the adjusting groove 6 is provided with multiple locking holes 14. The adjusting block 12 is connected to the locking holes 14 via the locking bolt 13. When adjusting and installing the second limiting block 7 according to the position of the first limiting block 5 inside the lower mold frame 3, the second limiting block 7 is moved by sliding the adjusting block 12 within the adjusting groove 6. Once the second limiting block 7 is symmetrical to the first limiting block 5, it is connected to the locking holes 14 via the locking bolt 13.

[0022] The upper mold frame 1 is symmetrically provided with upper slide plate straight edge and arc edge positioning blocks 15, and the lower mold frame 3 is symmetrically provided with lower slide plate straight edge and arc edge positioning blocks 16. By setting the upper slide plate straight edge and arc edge positioning blocks 15 and the lower slide plate straight edge and arc edge positioning blocks 16, the installation state of the upper slide plate body 2 and the lower slide plate body 4 can be further accurately positioned.

[0023] This invention provides a first limiting block 5 inside one side of the lower mold frame 3, and an adjustment groove 6 on the side wall of the lower slide body 4 away from the first limiting block 5. A second limiting block 7 is detachably installed in the adjustment groove 6. When the lower slide body 4 is installed backwards, the second limiting block 7 is resisted by the first limiting block 5, preventing the lower slide body 4 from being installed into the lower mold frame 3. This avoids the problem of reverse installation and can effectively improve the installation accuracy of the upper and lower slides.
