Description

Technical Field

[0001] This utility model relates to the field of smelting equipment technology, specifically to a vertical movable section arc-shaped structure for a billet continuous casting machine. Background Technology

[0002] In the continuous casting process of billets, the accuracy of the arc alignment directly affects the quality of the cast billet and production efficiency. Currently, common arc alignment devices mostly use online overhead cranes to adjust the crystallizer and sector section of horizontal continuous casting machines. However, this method has many shortcomings in practical applications. Traditional arc alignment methods rely on manual operation, making it difficult to guarantee high-precision arc alignment requirements and easily leading to the accumulation of errors due to human factors. Fine adjustments are difficult to make during the hoisting process, and the installation and calibration of the equipment require repeated adjustments, resulting in low arc alignment efficiency and increased downtime. In addition, the arc alignment of the continuous casting machine needs to meet specific surface requirements, but existing arc alignment structures often cannot ensure precise matching of various parts, easily leading to arc deviations and affecting the quality of the cast billet. Especially when changing to different specifications of billets, the complexity of equipment adjustment makes it difficult to quickly complete the arc alignment, further affecting the continuity and stability of production. Utility Model Content

[0003] To overcome the above shortcomings, the purpose of this utility model is to provide a vertical movable section arc alignment structure for a billet continuous casting machine. It uses an arc-shaped template to calibrate the position of the rollers and ensures that the rollers are arranged in a regular arc shape. The operation is simple, and because it is a vertical arc alignment structure, it can simulate the online arc alignment situation to the greatest extent and ensure high arc alignment accuracy.

[0031] like Figures 1 to 7 As shown, this utility model discloses a vertical movable section arc-shaped structure for a billet continuous casting machine, comprising:

[0032] Platform 1, which is used to provide support;

[0033] The continuous casting machine 2 is installed in the frame 1. The continuous casting machine has an arc-shaped movable section 20. The continuous casting machine 2 also includes an outer roller assembly 21, an inner roller assembly 22, a left roller assembly 23 and a right roller assembly 24 movably installed on the movable section 20.

[0034] The arc-shaped template 3 can extend into the interior of the continuous casting machine 2. The arc-shaped template 3 has an outer arc surface 31 and an inner arc surface 32, a left support surface 33 and a right support surface 34. The outer roller assembly 21, the inner roller assembly 22, the left roller assembly 23 and the right roller assembly 24 can fit into the arc-shaped template 3.

[0035] A horizontal reference plate 4 is detachably installed on the upper surface of the continuous casting machine 2.

[0036] The upper end face of the continuous casting machine 2 is provided with an outer arc pin hole 25 and an inner arc pin hole 26 for mounting the horizontal reference plate 4. The arc template 3 is closely attached to the horizontal reference plate 4 and moves along its length direction to adjust the position of the arc template 3 in the continuous casting machine 2.

[0037] With the above structure, the movable section 20 of the continuous casting machine 2 is vertical, and the arc-shaped template 3 can extend into the continuous casting machine 2. Its outer arc surface 31, inner arc surface 32, left support surface 33, and right support surface 34 respectively fit against the outer roller assembly 21, inner roller assembly 22, left roller assembly 23, and right roller assembly 24. The arc-shaped template 3 is positioned by a horizontal reference plate 4, which is detachably mounted on the upper end face of the continuous casting machine 2 via outer arc pin holes 25 and inner arc pin holes 26. This allows the arc-shaped template 3 to fit tightly against the horizontal reference plate 4. The arc-shaped template 3 can move along its length to adjust its position within the continuous casting machine 2 to adapt to different billet requirements, ensuring that the arc-shaped template 3 remains stable during adjustment and that misalignment or shaking does not affect casting accuracy.

[0038] In this embodiment, to further enhance the stability and positioning accuracy of the arc-shaped template 3, the arc-aligning structure of the billet continuous casting machine also includes a lower support seat 7. The lower support seat 7 is mounted on the frame 1 and located below the continuous casting machine 2, providing support and precise positioning for the arc-shaped template 3. The lower support seat 7 has a positioning shaft 71, which is used to engage with the arc-shaped template and provide positioning support for the arc-shaped template 3. Correspondingly, the arc-shaped template 3 has an inner arc positioning groove 35 and an outer arc positioning groove 36. When the inner arc positioning groove 35 of the arc-shaped template 3 engages with the positioning shaft 71, the inner roller assembly 22 fits against the inner arc surface 32 of the arc-shaped template 3, ensuring precise control of the inner arc contour of the billet; when the outer arc positioning groove 36 of the arc-shaped template 3 engages with the positioning shaft 71, the outer roller assembly 21 fits against the outer arc surface 31 of the arc-shaped template 3, ensuring precise control of the outer arc contour of the billet. Furthermore, when the inner arc positioning groove 35 or outer arc positioning groove 36 of the arc template 3 is engaged with the positioning shaft 71, the arc template 3 can also move left and right along the length direction of the positioning shaft 71. When the arc template 3 is located at the leftmost end of the positioning shaft 71, the left roller assembly 23 can be adjusted and fits against the left support surface 33 of the arc template 3, thereby ensuring that the left roller assembly 23 is located in the accurate billet position; when the arc template 3 is located at the rightmost end of the positioning shaft 71, the right roller assembly 24 can be adjusted and fits against the right support surface 34 of the arc template 3, thereby ensuring that the right roller assembly 24 is located in the accurate billet position. By setting the engagement structure between the lower support seat 7 and the arc template 3, the outer roller assembly 21, inner roller assembly 22, left roller assembly 23 and right roller assembly 24 are fitted against the arc template 3, reducing the error of manual adjustment and improving the stability and ease of operation of the continuous casting machine 2.

[0039] In this embodiment, the upper end face of the continuous casting machine 2 is also provided with a first pin 27 for installing the crystallizer, thereby maintaining the initial shape of the billet during the casting process and ensuring casting quality. In addition, in order to further improve the stability of the overall structure, the lower part of the continuous casting machine 2 is fixed to the frame 1 by the first bolt 5, and the upper reference seat 28 is fixedly connected to the frame 1, making the entire system more stable and thus avoiding a decrease in casting quality caused by vibration or displacement.

[0040] In this embodiment, the outer roller assembly 21, inner roller assembly 22, left roller assembly 23, and right roller assembly 24 are all mounted on the movable section 20 of the continuous casting machine 2 by the second bolt 6 and the set screw 61. The outer roller assembly 21, inner roller assembly 22, left roller assembly 23, and right roller assembly 24 have the same structure. Taking the left roller assembly 23 as an example, the left roller assembly includes a left roller and a fixing member connecting the left roller. The fixing member is mounted on the frame of the continuous casting machine 2, and the part of the fixing member that connects to the left roller can extend into the interior of the continuous casting machine 2 to clamp the billet and thus shape it. The fasteners used for mounting on the frame of the continuous casting machine 2 include the second bolt 6 and the set screw 61. The second bolt 6, as the primary fixing method, provides strong mechanical connection force, ensuring the left roll assembly 23 is firmly mounted on the frame of the continuous casting machine 2, maintaining stability even in high-temperature operating environments and preventing loosening or displacement due to vibration or impact. The set screw 61, on the other hand, plays a supporting role in fixing and fine-tuning. Compared to relying solely on the second bolt 6 for fixing, the set screw 61 can more precisely control the position of the left roll assembly 23. The set screw 61 controls the length screwed into the fastener, thereby controlling the distance between the left roll assembly 23 and the curved template 3. Finally, by tightening the second bolt 6, the fastener is fixed to the frame of the continuous casting machine 2, ultimately achieving the effect of arc correction.

[0041] The technical solution of this utility model has been described in conjunction with the preferred embodiments shown in the accompanying drawings. However, it will be readily understood by those skilled in the art that the protection scope of this utility model is obviously not limited to these specific embodiments. Without departing from the principle of this utility model, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will all fall within the protection scope of this utility model.
