Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of anti-deviation measuring tools, specifically an anti-deviation measuring tool for the mold during the construction process of a continuous casting tundish. Background Technology
[0002] During continuous casting, molten steel is poured from the ladle into the tundish, then flows into the crystallizer where it is cooled and finally forms a steel billet. The tundish is an intermediate step in the steelmaking process, serving as a metallurgical reactor and playing a crucial role in improving steel yield and quality. Whether for the smooth operation of continuous casting or for ensuring the required steel quality, the tundish functions to divert flow, facilitate continuous casting, reduce pressure, protect the casting process, and adsorb inclusions in the molten steel.
[0003] The tundish consists of a steel shell and refractory materials from the outside in. The working layer of the tundish is in direct contact with the molten steel, and its construction quality and material stability are crucial for continuous casting production. Magnesia-based dry refractory materials are commonly used for the working layer of the tundish.
[0004] However, because dry casting requires the working layer mold to be placed inside the tundish during construction, a working layer of a certain thickness is formed between the construction mold and the permanent layer. After vibration, baking, and cooling, the working layer is demolded. The tundish can be used normally when the continuous casting baking temperature reaches about 1100℃ after construction. However, if the construction thickness of the working layer is not uniform, it will affect the stability of the working layer of the tundish, causing the refractory material to collapse at the point where the strength is insufficient during the continuous casting baking process. Utility Model Content
[0005] (a) Technical problems to be solved
[0006] To address the shortcomings of existing technologies, this utility model provides a mold anti-deviation measuring tool for the construction process of continuous casting tundish, which solves the problem mentioned in the background art that when the construction thickness of the working layer is inconsistent, it will affect the stability of the working layer of the tundish and cause the refractory material to collapse at the point of insufficient strength during the continuous casting baking process.
[0007] (II) Technical Solution
[0008] To achieve the above objectives, this utility model provides the following technical solution: a measuring tool for preventing deviation of the formwork during the construction process of a continuous casting tundish, comprising:
[0009] A first connecting rod, with a handle installed at the top end of the first connecting rod and a second connecting rod welded to the bottom end of the first connecting rod;
[0010] A first measuring rod is disposed at one end of a second connecting rod, and a second measuring rod is installed at the other end of the second connecting rod.
[0011] A balance plate is disposed on the outer periphery of the first connecting rod, and a limiting plate is provided at the bottom of the balance plate.
[0012] Preferably, positioning rings are installed on both sides of the upper surface of the balance plate. The positioning ring on the left side is installed on the upper surface of the balance plate, and the positioning ring on the right side is not connected to the balance plate. The balance plate can be installed on the surface of the first connecting rod through the positioning rings.
[0013] Preferably, connecting plates are installed on both the front and back of the positioning ring, and bolts are screwed between the connecting plates. Rotating the bolts can control the squeezing force of the positioning ring on the first connecting rod, thereby controlling the height of the balance plate.
[0014] Preferably, the bottom of the balance plate is provided with a moving groove, and a threaded rod is installed in the inner cavity of the moving groove through a bearing.
[0015] Preferably, a movable block is embedded in the inner cavity of the movable groove. The movable block is screwed to the surface of the threaded rod, and the bottom of the movable block is connected to the surface of the limiting plate. Rotating the threaded rod can drive the movable block to move, thereby driving the limiting plate to move.
[0016] Beneficial effects
[0017] Compared with the prior art, this utility model provides a measuring tool for preventing deviation of the formwork during the construction process of continuous casting tundish, which has the following beneficial effects:
[0018] This continuous casting tundish construction process mold anti-deviation measuring tool, controlled by a handle, inserts the first connecting rod into the cavity between the permanent layer and the working layer mold, which in turn drives the second connecting rod into the measuring space. Simultaneously, the balance plate contacts the upper surface of the tundish, preventing the second connecting rod from shifting. Furthermore, the limiting plate cooperates with the first connecting rod to lock onto the outer edge of the tundish, preventing the second connecting rod from shaking during measurement. Thus, by measuring the uniformity of the cavity thickness between the permanent layer and the working layer mold of the tundish using the first and second measuring rods, it can prevent refractory collapse at insufficient strength points during the continuous casting baking process caused by inconsistent working layer construction thickness.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0026] This utility model provides a technical solution: a measuring tool for preventing deviation of the formwork during the construction process of a continuous casting tundish. (Please refer to...) Figure 1 It includes a first connecting rod 1, a handle 2 is installed at the top of the first connecting rod 1, and a second connecting rod 3 is welded to the bottom of the first connecting rod 1;
[0027] Please see Figure 2 The first measuring rod 4 is set at one end of the second connecting rod 3, and the other end of the second connecting rod 3 is equipped with the second measuring rod 5;
[0028] Please see Figure 1 Balance plate 6 is set on the outer periphery of the first connecting rod 1, and a limiting plate 13 is provided at the bottom of balance plate 6;
[0029] By controlling the first connecting rod 1 to be inserted into the cavity between the permanent layer and the working layer mold by the handle 2, the second connecting rod 3 can be inserted into the measuring space. At the same time, the balance plate 6 will also contact the upper surface of the tundish, which can prevent the second connecting rod 3 from shifting. The limiting plate 13 cooperates with the first connecting rod 1 to be locked on the outer edge of the tundish, which can prevent the second connecting rod 3 from shaking during measurement. Thus, by measuring the thickness of the cavity between the permanent layer and the working layer mold of the tundish by the first measuring rod 4 and the second measuring rod 5, it can be determined whether the thickness is uniform, which can prevent the refractory material from collapsing due to insufficient strength in the continuous casting baking process caused by inconsistent working layer construction thickness.
[0030] Please see Figure 3 Positioning rings 7 are installed on both sides of the upper surface of the balance plate 6. The positioning ring 7 on the left side is installed on the upper surface of the balance plate 6, while the positioning ring 7 on the right side is not connected to the balance plate 6. The balance plate 6 can be installed on the surface of the first connecting rod 1 through the positioning rings 7.
[0031] Connecting plates 8 are installed on both the front and back of the positioning ring 7. Bolts 9 are screwed between the connecting plates 8. Rotating the bolts 9 can control the squeezing force of the positioning ring 7 on the first connecting rod 1, thereby controlling the height of the balance plate 6.
[0032] Please see Figure 4 The bottom of the balance plate 6 is provided with a moving groove 10, and the inner cavity of the moving groove 10 is fitted with a threaded rod 11 through a bearing.
[0033] The inner cavity of the movable groove 10 is embedded with a movable block 12. The movable block 12 is screwed to the surface of the threaded rod 11. The bottom of the movable block 12 is connected to the surface of the limiting plate 13. Rotating the threaded rod 11 can drive the movable block 12 to move, thereby driving the limiting plate 13 to move.
[0034] In operation, this solution works as follows: First, the first connecting rod 1 is inserted into the cavity between the permanent layer and the working layer mold by controlling the handle 2. This allows the second connecting rod 3 to be inserted into the measuring space. Then, rotating the bolt 9 controls the squeezing force of the positioning ring 7 on the first connecting rod 1, thereby controlling the height of the balance plate 6. The balance plate 6 also contacts the upper surface of the tundish, preventing the second connecting rod 3 from shifting. Rotating the threaded rod 11 moves the moving block 12, which in turn moves the limiting plate 13. The limiting plate 13, in conjunction with the first connecting rod 1, engages with the outer edge of the tundish, preventing the second connecting rod 3 from shaking during measurement. Finally, the uniformity of the cavity thickness between the permanent layer and the working layer mold of the tundish is checked by the first measuring rod 4 and the second measuring rod 5. Please refer to [link to relevant documentation]. Figure 5 When the tool measures the corresponding sides of points A and B, if both the first measuring rod 4 and the second measuring rod 5 can be inserted into the cavity between the permanent layer and the working layer mold, it indicates that the thickness of the cavity (working layer) between the permanent layer and the working layer mold of the intermediate liner is uniform. If one side cannot be inserted, it indicates that the working layer mold is misaligned and the mold position needs to be adjusted and measured again until the thickness of the corresponding sides of points A and B is uniform.
