Description

Technical Field

[0001] This utility model relates to the field of smelting equipment technology, specifically to a sector section structure for a continuous casting machine for irregularly shaped billets. Background Technology

[0002] Continuous casting machines for irregularly shaped billets are used to cast molten metal into specific shapes. The fan-shaped section, as a crucial component of this process, is responsible for cooling and solidifying the molten metal into the desired shape. The fan-shaped section is designed to accommodate variations in billet shape and is typically used to produce billets of special shapes. Rollers are usually used in the fan-shaped section of irregularly shaped billet continuous casting machines to support the billet and ensure that it does not undergo excessive deformation during cooling.

[0003] Existing continuous casting machines typically place the roller mounting surfaces inside the sector section, making roller maintenance and adjustment relatively complex. The space within the sector section is usually quite narrow, requiring high technical skills and ample operating space for roller replacement, adjustment, and lubrication. Furthermore, machining irregularly shaped billets is very difficult, necessitating the purchase of specialized cutting tools, which is costly. Utility Model Content

[0004] To overcome the above shortcomings, the purpose of this utility model is to provide a sector section structure for a continuous casting machine for irregular billets, which installs the roller assembly on the outer surface of the sector frame, simplifies the overall structure and the complexity of the sector section, facilitates maintenance and adjustment, and greatly reduces the processing cost of irregular billets.

[0005] Technical solution: This utility model discloses a sector-shaped section structure for a continuous casting machine for irregularly shaped billets, used to clamp irregularly shaped billets and maintain their shape, including:

[0006] A fan-shaped frame, comprising two fan-shaped support frames located on both sides and an inner arc support frame and an outer arc support frame connecting the fan-shaped support frames;

[0007] At least one roller assembly is mounted on the outer surface of only one of the sector support frame, inner arc support frame or outer arc support frame, and the roller assembly is capable of extending into the interior of the sector frame to clamp the irregular blank.

[0008] Furthermore, the roller assembly includes an inner arc roller assembly, an outer arc roller assembly, and a side arc roller assembly, all of which are bolted to the outer surface of the sector frame.

[0009] Furthermore, the inner arc roller assembly is mounted on the inner arc support frame, the outer arc roller assembly is mounted on the outer arc support frame, and the side arc roller assembly is mounted on the fan-shaped support frame.

[0010] Furthermore, the inner arc support frame, the outer arc support frame, and the fan-shaped support frame are respectively provided with mounting holes for mounting the inner arc roller assembly part, the outer arc roller assembly part, and the side arc roller assembly part.

[0011] Furthermore, it also includes two sets of first spray pipes and two sets of second spray pipes. The first spray pipes are respectively installed on one side of the inner arc support frame and the outer arc support frame, and the second spray pipes are respectively installed on one side of the fan-shaped support frame. Both the first spray pipes and the second spray pipes face the irregular blank.

[0012] Furthermore, it also includes a support, which is mounted on the outer arc support frame to support and fix the sector frame.

[0013] Furthermore, the inner arc roller assembly includes an inner arc roller, two inner flange rollers, and a first transition connecting plate. The inner flange rollers are located on both sides of the inner arc roller, and both the inner arc rollers and the inner flange rollers are mounted on the first transition connecting plate. The outer arc roller assembly includes an outer arc roller, two outer flange rollers, and a second transition connecting plate. The outer flange rollers are located on both sides of the outer arc roller, and both the outer arc rollers and the outer flange rollers are mounted on the second transition connecting plate.

[0014] Furthermore, the inner arc support frame also includes several horizontally arranged first ribs, the outer arc support frame also includes several horizontally arranged second ribs, and the fan-shaped support frame includes several horizontally arranged side ribs.

[0015] The beneficial effects of this utility model are as follows:

[0016] (1) The fan-shaped section structure of the irregular billet continuous casting machine described in this utility model fully clamps the irregular billet and maintains its shape by installing the roller assembly on the outer surface of the inner arc support frame, the outer arc support frame and the fan-shaped support frame respectively, thereby improving the support force of the irregular billet and preventing deformation or twisting during the continuous casting process, thus ensuring the shape and quality of the billet.

[0017] (2) The present invention sets the mounting surface of the roller assembly on the outer surface of the fan-shaped frame, which greatly reduces the difficulty of installing and adjusting the roller assembly, and at the same time reduces the processing cost;

[0028] The following is in conjunction with the appendix Figure 1-6 The present invention will be further illustrated by the following specific embodiments.

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. The implementation methods of this utility model will now be described based on its overall structure.

[0030] like Figures 1 to 6 As shown, the sector-shaped section structure of the irregular billet continuous casting machine of this utility model is used to clamp and maintain the shape of the irregular billet, including:

[0031] The fan-shaped frame 2 includes two fan-shaped support frames 21 located on both sides and an inner arc support frame 22 and an outer arc support frame 23 connecting the fan-shaped support frames 21.

[0032] At least one roller assembly is mounted on the outer surface of one and only one of the sector support frame 21, inner arc support frame 22 or outer arc support frame 23, and the roller assembly is capable of extending into the interior of the sector frame 2 to clamp the irregular blank 1.

[0033] With the above structure, when the shaped billet 1 of the continuous casting machine of this utility model enters the fan-shaped frame 2, the roller assembly can extend into the inside of the fan-shaped frame 2, thereby clamping the shaped billet 1 and maintaining its shape. The roller assembly, through rotation and pushing, keeps the position of the shaped billet 1 stable during the continuous casting process, avoiding tilting, displacement or deformation of the shaped billet 1 due to uneven pressure.

[0034] Specifically, compared to traditional continuous casting machines, the mounting surface of the roller assembly is usually located inside the fan-shaped frame 2. This not only increases the complexity of installation and maintenance but also makes it difficult to effectively adjust and inspect the rollers due to space constraints. The narrow space inside the fan-shaped frame 2 makes roller replacement, adjustment, or repair very cumbersome, often requiring the disassembly of some structural components, resulting in long downtime and impacting production efficiency. This invention, by setting the roller assembly on the outer surface of the fan-shaped support frame 21, completely avoids the space constraints of traditional internal installation, providing a wider operating space for externally mounted roller assemblies. This facilitates installation, adjustment, inspection, and replacement, greatly reducing maintenance difficulty and costs. Furthermore, external installation allows for more intuitive adjustment of the roller assembly. Operators can precisely adjust the roller pressure and position through manual or automatic control systems to adapt to irregularly shaped billets 1 of different shapes and sizes, thereby improving work efficiency and accuracy.

[0035] like Figure 2 and Figure 3As shown, in this embodiment, the roller assembly includes an inner arc roller assembly 31, an outer arc roller assembly 32, and a side arc roller assembly 33, all of which are bolted to the outer surface of the sector frame 2. In traditional designs, the roller assembly needs to be installed inside the frame, which not only limits the operating space but also increases the installation difficulty, making the adjustment and maintenance of the rollers more complex. Installing the roller assembly on the outer surface allows operators to more easily access each roller for adjustment, inspection, and replacement, significantly reducing maintenance time and improving work efficiency. Furthermore, the bolted fixing method ensures a firm connection between the roller assembly and the sector frame 2, enabling it to withstand larger workloads and preventing loosening or displacement of the roller assembly during operation. The external installation method allows for more direct and stable contact between the rollers and the shaped billet 1, and also allows for precise adjustment of the clamping force, ensuring that the shaped billet 1 maintains a stable shape throughout the continuous casting process, avoiding deformation or displacement of the shaped billet 1 due to uneven clamping. Specifically, the inner arc roller assembly 31 is mounted on the inner arc support frame 22, the outer arc roller assembly 32 is mounted on the outer arc support frame 23, and the side arc roller assembly 33 is mounted on the fan-shaped support frame 21. The inner arc roller assembly 31, mounted on the inner arc support frame 22, is used to clamp the inner arc portion of the shaped billet 1; the outer arc roller assembly 32, mounted on the outer arc support frame 23, is used to clamp the outer arc portion of the billet, providing strong external support to ensure the shape stability of the shaped billet 1 during the casting process; the side arc roller assembly 33, mounted on the fan-shaped support frame 21, is responsible for clamping both sides of the shaped billet 1, playing an auxiliary clamping role, thereby achieving comprehensive support for the entire shaped billet 1. Correspondingly, the inner arc support frame 22, the outer arc support frame 23 and the fan-shaped support frame 21 are respectively provided with mounting holes 4 for mounting the inner arc roller assembly part 31, the outer arc roller assembly part 32 and the side arc roller assembly part 33, thereby ensuring that each assembly part can be firmly and accurately installed in the corresponding position, thus ensuring the overall stability and performance of the clamping system.

[0036] In this embodiment, the fan-shaped section structure of the continuous casting machine for the shaped billet 1 also includes two sets of first spray pipes 51 and two sets of second spray pipes 52. The first spray pipes 51 are respectively installed on one side of the inner arc support frame 22 and the outer arc support frame 23, while the second spray pipes 52 are respectively installed on one side of the fan-shaped support frame 21. These spray pipes are all designed to face the shaped billet 1, thereby providing cooling or cleaning for the billet 1. Because the coolant is sprayed evenly, deformation, cracks, or other surface defects caused by uneven temperature during continuous casting can be effectively prevented, ensuring the shape and quality of the shaped billet 1. The first spray pipes 51 and the second spray pipes 52 not only effectively control the temperature of the shaped billet 1, ensuring that the shaped billet 1 maintains a stable shape during continuous casting, but also prevent defects on the surface of the shaped billet 1 caused by excessive cooling or uneven temperature.

[0037] like Figure 4 and Figure 5 As shown in this embodiment, the sector section structure of the continuous casting machine for the irregular billet 1 also includes a support 6. The support 6, connected to the outer arc support frame 23, provides stable support for the entire sector frame 2, ensuring that the sector frame 2 maintains a stable structural state during operation, thereby guaranteeing the normal operation of the roller assembly and other components. The support 6 allows the sector frame 2 to be firmly fixed in the required position, preventing displacement due to vibration or external forces. The support 6 and the outer arc support frame 23 can be installed using bolts or other fastening methods to ensure the stability of their connection.

[0038] like Figure 2 , Figure 3 and Figure 6 As shown, in this embodiment, the inner arc roller assembly 31, the outer arc roller assembly 32, and the side arc roller assembly 33 each include different types of rollers and connecting components. Specifically, the inner arc roller assembly 31 includes an inner arc roller 311, two inner flange rollers 312, and a first transition connecting plate 313. The inner flange rollers 312 are located on both sides of the inner arc roller 311, and both the inner arc roller 311 and the inner flange rollers 312 are mounted on the first transition connecting plate 313. The outer arc roller assembly 32 includes an outer arc roller 321, two outer flange rollers 322, and a second transition connecting plate 323. The outer flange rollers 322 are located on both sides of the outer arc roller 321, and both the outer arc roller 321 and the outer flange rollers 322 are mounted on the second transition connecting plate 323. The side arc roller assembly 33 includes a side arc roller 331 and a side arc connecting plate 332. The first transition connecting plate 313, the second transition connecting plate 323, and the side arc connecting plate 332 are aligned with the assembly hole 4 and fixedly connected by bolts. The inner arc roller 311 and the outer arc roller 321 are used to clamp the main body of the irregular blank 1. The inner flange rollers 312 located on both sides of the inner arc roller 311 and the outer flange rollers 322 located on both sides of the outer arc roller 321 cooperate to clamp the two flanges of the irregular blank 1, thereby ensuring that the irregular part can be stably processed. The parts of the first transition connecting plate 313, the second transition connecting plate 323, and the side arc connecting plate 332 used to connect the rollers are all structures that can extend into the fan-shaped frame 2 and allow the corresponding rollers to clamp the irregular blank 1.

[0039] The combination of the connecting plate and the rollers allows for precise installation of the rollers in preset positions, effectively avoiding potential roller position deviations or asymmetries. Secondly, the bolted connection method ensures the robustness and reliability of the assembled components, maintaining stable operation even during prolonged high-intensity operation and reducing the frequency of maintenance and adjustments. Through a reasonable roller distribution and installation position setting, the inner arc roller 311, outer arc roller 321, and side arc roller 331 can evenly clamp and support the irregularly shaped billet 1, ensuring the stability of the billet during continuous casting and preventing deformation or other production defects.

[0040] like Figure 4 As shown, in this embodiment, the inner arc support frame 22 further includes several horizontally arranged first ribs 71, the outer arc support frame 23 further includes several horizontally arranged second ribs 72, and the fan-shaped support frame 21 includes several horizontally arranged side ribs 73. By designing horizontal ribs on the support frame, the overall strength and rigidity of the support frame can be effectively enhanced, thereby improving the stability and durability of the entire fan-shaped frame 2. The ribs can significantly increase the support frame's resistance to bending and deformation. Since the support frame needs to withstand large mechanical stresses and temperature changes during use, the ribs reduce stress concentration in the material by providing additional structural support, preventing deformation of the support frame due to external forces or thermal expansion and contraction.

[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.
