Description

Technical Field

[0001] This utility model belongs to the field of continuous casting machine technology, specifically relating to a guide device for the arc section of a continuous casting machine and a straightening machine frame. Background Technology

[0002] Continuous casting machines solidify molten steel into billets of a specific shape. The arc section is a crucial component of the continuous casting machine. In this section, the billet moves along a specific arc-shaped trajectory. A series of devices within the arc section cool and support the billet, facilitating its gradual solidification. The straightening machine applies tension to the billet after it has exited the mold and undergone cooling and solidification, ensuring its smooth passage through subsequent production processes. It also straightens the billet when necessary, guaranteeing that its shape and quality meet requirements.

[0003] In the continuous casting process, existing curved sections and straightening frame guiding equipment have many defects. First, the high-temperature environment easily causes equipment deformation. The temperature during continuous casting is extremely high, and ordinary guiding equipment is prone to thermal deformation under prolonged high temperatures. For example, in a steel plant, the deformation of the guiding equipment at high temperatures led to cracks on the surface of the cast billet, seriously affecting the quality of the billet. Second, the parameters of the guide rollers are unreasonable. For example, the outer diameter and intermediate aperture of the guide rollers do not match the actual requirements, making it impossible to accurately guide the cast billet and reducing production efficiency. Furthermore, installation and maintenance are inconvenient. The equipment's installation structure is complex, and maintenance requires a lot of time and manpower. A factory once experienced increased downtime and a significant increase in production costs due to the cumbersome installation of the guiding equipment. These problems not only reduce the quality of the cast billet but also increase downtime, ultimately leading to a significant increase in production costs.

[0004] Therefore, this utility model provides a guide device for the arc section of a continuous casting machine and a straightening machine frame to solve the problems mentioned in the background art. Utility Model Content

[0005] In response to the problems raised in the background technology above, the purpose of this utility model is to provide a guide device for the arc section of a continuous casting machine and the straightening machine frame. Through the design of setting water cooling pins, reasonable guide roller size and buffer structure, the device has significant improvements in high temperature adaptability, guiding accuracy and maintenance convenience, thereby bringing comprehensive benefits such as extended equipment life and improved production efficiency.

[0006] To achieve the above-mentioned technical objectives, the technical solution adopted by this utility model is as follows: A guide device for the arc section of a continuous casting machine and a straightening machine frame includes a first mounting base, a second mounting base, a first fixing plate, a second fixing plate, a guide roller, and a pin shaft; The first fixing pieces are respectively disposed on both sides of the first mounting base, and the two first fixing pieces are respectively connected to the side wall of the first mounting base. The second mounting base is fixedly connected to the inner side of the first fixing pieces. The second fixing plate is disposed inside the first fixing plate. One end of the second fixing plate is connected to the guide roller by a pin. The pin passes through the second fixing plate and the guide roller in sequence and is fixedly connected by bolts.

[0007] Further specified, the first mounting base is provided with a first mounting hole and a second mounting hole, the diameter of the second mounting hole is larger than that of the first mounting hole, and the first mounting hole and the second mounting hole are used to fix the guide device on the arc section of the continuous casting machine or the straightening machine frame.

[0008] Further, it also includes a first connecting shaft and a second connecting shaft, both of which are installed between two first fixing plates. The first connecting shaft passes through the mounting hole corresponding to the top of the first fixing plate, and the second connecting shaft passes through the mounting holes corresponding to the bottom of the first fixing plate and the second fixing plate in sequence.

[0009] Furthermore, the guide roller is sleeved on the pin shaft, forming a rotatable connection with the pin shaft. The guide roller can rotate freely around the pin shaft, and a bearing connects the pin shaft and the guide roller. This structural design enables the guide roller to guide the movement of the cast billet while ensuring smooth rotation.

[0010] Furthermore, the pin shaft is perforated and equipped with a water-passing structure for introducing coolant to cool the guide roller.

[0011] Further specified, the outer diameter of the guide roller is not less than 22cm, the central aperture is not less than 7cm, and the surface of the guide roller is sequentially connected with a wear-resistant layer and an anti-corrosion layer. This structural design, with its dimensional parameters, better adapts to the running and guiding requirements of the cast billet, improving the accuracy of billet guidance, while also enhancing the wear resistance and corrosion resistance of the guide roller.

[0012] Further defining the structure, it also includes a spring, the bottom of which is connected to the second mounting base, and the top of which is connected to the second fixing plate. This structural design allows the spring to act as a buffer, reducing the impact force on the guide rollers during the casting process and extending the service life of the guide rollers.

[0013] Further, it also includes another set of guiding devices, with the guide rollers of the two sets of guiding devices spaced at least 20cm apart. This structural design provides universal adaptability, making it suitable for guiding the movement of various sizes of cast billets. When the size of the cast billet changes, the spacing of the guide rollers can be fine-tuned within a certain range to better adapt to the production needs of different sizes of cast billets.

[0014] The beneficial effects of this utility model are: In this design, the dynamic response of the guiding device is triggered as the billet moves within the continuous casting machine. Two guide rollers are positioned opposite each other, with the billet located between them. The guide rollers rotate with the billet's movement, providing guidance and ensuring it moves along a predetermined trajectory. Water flows inside the pin shaft; during operation, the coolant continuously carries away heat generated by the guide rollers, effectively preventing deformation due to high temperatures. A spring is positioned between the guide rollers and the connecting shaft; when the billet's movement generates impact, the spring acts as a buffer, reducing the impact on the guide rollers. The coordinated operation of all components ensures stable operation of the equipment during the billet production process.

[0015] This solution significantly improves high-temperature adaptability, guiding accuracy, and ease of maintenance through designs such as water cooling for the pin shaft, reasonable guide roller dimensions, and buffer structure, thereby bringing comprehensive benefits such as extended equipment life and increased production efficiency.

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.

[0021] like Figures 1-5 As shown, the present invention provides a guide device for the arc section of a continuous casting machine and a straightening machine frame, including a first mounting base 1, a second mounting base 2, a first fixing plate 5, a second fixing plate 6, a guide roller 8, and a pin shaft 10. The first fixing pieces 5 are respectively disposed on both sides of the first mounting base 1, and the two first fixing pieces 5 are respectively connected to the side wall of the first mounting base 1. The second mounting base 2 is fixedly connected to the inner side of the first fixing pieces 5. The second fixing plate 6 is disposed inside the first fixing plate 5. One end of the second fixing plate 6 is connected to the guide roller 8 through a pin 10. The pin 10 passes through the second fixing plate 6 and the guide roller 8 in sequence and is fixedly connected by bolts.

[0022] In the practical application of this embodiment, the first mounting base 1 is provided with a first mounting hole 3 and a second mounting hole 4. The diameter of the second mounting hole 4 is larger than that of the first mounting hole 3. The first mounting hole 3 and the second mounting hole 4 are used to fix the guiding device on the arc section of the continuous casting machine or the straightening machine frame.

[0023] In the practical application of this embodiment, a first connecting shaft 7 and a second connecting shaft 11 are also included. The first connecting shaft 7 and the second connecting shaft 11 are both installed between two first fixing plates 5. The first connecting shaft 7 passes through the mounting hole corresponding to the top of the first fixing plate 5, and the second connecting shaft 11 passes through the mounting holes corresponding to the bottom of the first fixing plate 5 and the second fixing plate 6 in sequence.

[0024] In the practical application of this embodiment, the guide roller 8 is sleeved on the pin 10, forming a rotatable connection with the pin 10. The guide roller 8 can rotate freely around the pin 10, and a bearing is provided between the pin 10 and the guide roller 8 for connection. This structural design enables the guide roller 8 to guide the movement of the casting billet while ensuring smooth rotation.

[0025] In the practical application of this embodiment, the pin 10 is perforated and a water passage structure is provided to allow coolant to be introduced to cool the guide roller 8.

[0026] In the practical application of this embodiment, the outer diameter of the guide roller 8 is not less than 22cm, the central aperture is not less than 7cm, and the surface of the guide roller 8 is sequentially connected with a wear-resistant layer and an anti-corrosion layer. This structural design allows the dimensional parameters to better adapt to the running and guiding requirements of the cast billet, improving the accuracy of billet guidance, while also enhancing the wear resistance and corrosion resistance of the guide roller.

[0027] In practical application of this embodiment, a spring 9 is also included. The bottom of the spring 9 is connected to the second mounting base 2, and the top of the spring 9 is connected to the second fixing plate 6. With this structural design, the spring 9 acts as a buffer, which can reduce the impact force on the guide roller 8 during the casting process and extend the service life of the guide roller 8.

[0028] In the practical application of this embodiment, another set of guiding devices is also included, and the distance between the guide rollers 8 of the two sets of guiding devices is at least 20cm. This structural design provides universal adaptability, making it suitable for guiding the movement of various specifications of cast billets. When the specifications of the cast billets change, the distance between the guide rollers 8 can be finely adjusted within a certain range to better adapt to the production needs of different specifications of cast billets.

[0029] The working principle of this utility model is as follows: As the billet moves within the continuous casting machine, the dynamic response of the guiding device is triggered. The guide rollers contact the billet and rotate with its movement, providing guidance and ensuring it moves along a predetermined trajectory. Water flows inside the pin shaft; during operation, the coolant continuously carries away the heat generated by the guide rollers due to high temperatures, effectively preventing deformation. Springs are positioned between the guide rollers and the connecting shaft; when the billet's movement generates impact, the springs buffer the impact, reducing its effect on the guide rollers. The coordinated operation of all components ensures stable operation of the equipment during billet production. Example 1:

[0030] In continuous casting machine production scenarios, this guiding device exhibits excellent adaptability. The guide roller 8 has an outer diameter of 22cm, a central aperture of 7cm, and a spacing of 20cm between the two guide rollers. These parameters effectively meet the guiding requirements of small-sized castings. For example, when producing castings for small parts, this device can provide precise guidance, ensuring casting quality. During routine maintenance, the bolts at the mounting holes should be checked periodically to ensure the device is securely installed and to prevent loose bolts from affecting the guiding effect.

[0031] The continuous casting machine in this solution requires high stability and a long service life. This guiding equipment performs excellently under high-frequency operation, capable of continuous operation for 100 hours without failure, extending its lifespan to 5 years. Under high-frequency production demands, such as in a steel plant's high-output continuous casting production line, using this equipment increased daily output by 15 tons, significantly improving production efficiency and reducing production costs. Example 2:

[0032] For continuous casting machines that need to produce billets of various sizes, this guiding device offers flexibility in adjusting the spacing of the guide rollers 8. The spacing of the guide rollers 8 can be adjusted within the range of 18-22cm, adapting to different billet sizes without requiring equipment replacement. For example, when producing 150mm×150mm and 200mm×200mm billets, simply adjusting the spacing between the two guide rollers 8 allows for rapid changeover, saving 30% of changeover time and improving production flexibility and efficiency.

[0033] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
