Abstract
Description
Technical Field
[0001] This utility model relates to the field of sector segment technology, and in particular to a cooling device for sector segments of a continuous casting machine. Background Technology
[0002] With the rapid development of my country's steel industry, my country's continuous casting equipment has also developed in tandem, creating conditions for the smooth and rapid development of the steel industry. The fan-shaped section is an important piece of equipment in the continuous casting machine. After the billet from the crystallizer passes through the bending section and reaches the fan-shaped section, the billet shell continues to grow in the fan-shaped section until the billet is completely solidified.
[0003] Currently, although the existing continuous casting machine sector section can complete the basic conveying of the billet and the continued growth of the billet shell, it cannot make precise guidance adjustments according to the actual position and size of the billet during this process. This leads to the billet easily deviating or getting stuck when it enters, affecting the stability and efficiency of the continuous casting operation. Utility Model Content
[0004] The purpose of this invention is to address the shortcomings of existing technologies that cannot accurately guide and adjust the casting based on the actual position and size of the billet, leading to billet deviation and jamming during entry, thus affecting the stability and efficiency of continuous casting operations. Therefore, this invention proposes a cooling device for the fan-shaped section of a continuous casting machine.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A cooling device for a sector section of a continuous casting machine, comprising:
[0007] The lower section has four support columns fixedly installed on its top in a rectangular shape, and the top of the four support columns is fixedly installed on the same upper section.
[0008] The lower section is provided with a guide component, which is used to guide the billet that is about to enter it and adjust the position of the billet inside.
[0009] In one possible design, the guide assembly includes two support frames symmetrically fixedly disposed on one side of the lower section. Each of the two support frames has two symmetrically formed grooves on its top. A slide is slidably disposed in each of the two grooves of the same support frame. Two guide frames are slidably disposed on the top of the support frame. The two slides are fixedly connected to the bottom of the two guide frames respectively. A double-outlet oil cylinder is embedded in each of the two support frames. The two piston ends of the double-outlet oil cylinder are fixedly connected to the two slides on the same support frame respectively.
[0010] In one possible design, the two guide frames located on the same support frame are T-shaped, with the front being larger than the back.
[0011] In one possible design, a plurality of evenly distributed lower rotating rollers are rotatably arranged on the top of the lower section, and a motor is fixedly arranged on one side of the top of the lower section, with the output shaft of the motor fixedly connected to one of the lower rotating rollers.
[0012] In one possible design, a connecting frame is slidably provided at the bottom of the upper section, and multiple evenly distributed upper rotating rollers are rotatably provided at the bottom of the connecting frame. A hydraulic cylinder is embedded in the top of the upper section, and the piston end of the hydraulic cylinder is fixedly connected to the top of the connecting frame.
[0013] In one possible design, cooling pipes are embedded inside both the lower and upper sections. Multiple connecting pipes are fixedly installed on both sides of the lower and upper sections. Two connecting pipes on the same side are fixedly connected to the same connecting pipe. A connector is provided on one side of the connecting pipe. The cooling pipes inside the lower and upper sections are respectively connected to the corresponding connecting pipes.
[0014] In one possible design, two fixed pipes are symmetrically fixedly arranged at the bottom of the lower section and the top of the upper section. Each fixed pipe is fixedly connected to a corresponding cooling pipe. Each fixed pipe is fixedly connected to a uniformly distributed spray pipe. One end of each spray pipe is fixedly connected to a water nozzle, and the multiple water nozzles are respectively directed towards the lower roller and the upper roller.
[0015] In this application, before the continuous casting operation begins, the device is first powered on, and then the connecting pipe is connected to the water source. After the billet exiting the crystallizer passes through the bending section, it enters the fan-shaped section for cooling. At this time, the guide frame is also in its initial set position, waiting for the arrival of the billet. As the billet moves, its front end is first guided and its position adjusted by the guide frame. The two guide frames located on the same support frame are T-shaped, wider at the front and narrower at the back, allowing the front end of the billet to enter the space between the two guide frames relatively easily. The guide frame begins to initially guide the direction of the billet's entry, enabling the billet to enter the fan-shaped section along a predetermined trajectory, avoiding any deviation or jamming of the billet. As the billet continues to enter the fan-shaped section... During the process, the guide frame will be dynamically adjusted according to the actual position and size of the billet. If the billet deviates in position due to insufficient width or is too wide to enter, the two piston ends of the double-outlet cylinder on the support frame will extend or retract simultaneously. The guide frame on the slide will move in opposite directions. When the billet is too wide and deviates, the control system will control the piston of the double-outlet cylinder to retract, so that the two guide frames retract and approach the billet, apply force to the billet, and guide the billet back to the correct position. When the width is too large, the control system will control the piston of the double-outlet cylinder to extend, so that the two guide frames move away from each other and expand the inlet.
[0016] If it is necessary to guide the slab billet, since the shape and size of the slab billet are different from those of ordinary billets, the operator will remove one of the guide frames that is close to each of the two support frames, leaving one guide frame on each of the two support frames. After removal, the two remaining guide frames that are far apart can better adapt to the shape and size of the slab billet, providing suitable guiding space for the slab billet to enter. When the slab billet enters, the guide frames still play a role in the above guiding process to ensure that the slab billet can enter the sector smoothly and accurately.
[0017] During the conveying process, the connecting frame at the bottom of the upper section can be adjusted up and down by a hydraulic cylinder. When it is necessary to adjust the distance between the upper and lower rollers to accommodate the conveying of billets of different thicknesses, the operator can control the piston extension and retraction of the hydraulic cylinder to drive the connecting frame to slide up and down, thereby changing the position of the upper roller and ensuring that the billet is subjected to appropriate pressure and support during the conveying process.
[0018] After the billet enters the sector section, it is conveyed between the lower and upper sections. Multiple lower rollers evenly distributed at the top of the lower section and multiple upper rollers installed at the bottom of the upper section via connecting frames jointly undertake the task of conveying the billet. At this time, the motor starts and drives the connected lower rollers to rotate. Due to the friction between the billet and the lower and upper rollers, the rotation of the lower rollers will drive the billet forward. At the same time, the upper rollers also rotate with the movement of the billet, thus achieving stable conveying of the billet.
[0019] During the billet conveying process, the cooling system simultaneously cools the billet. Cooling water enters the connecting pipe through the connector, then flows into the connecting pipes on both sides, and then into the cooling pipes inside the lower and upper forming sections, forming a cooling water circulation loop. This removes the heat inside the lower and upper forming sections. After flowing from the cooling pipes into the fixed pipe, the cooling water is further distributed into multiple evenly distributed spray pipes. The cooling water is sprayed from the water nozzles, directly spraying onto the lower and upper rotating rollers to cool the surface of the billet. Through heat conduction, the heat transferred from the billet to the rotating rollers is removed, thus achieving the cooling of the billet.
[0020] This utility model has the following beneficial effects:
[0021] In this invention, the guide component can provide initial guidance for the entry of the billet to avoid deviation. The position of the guide frame can be adjusted according to the actual position and size of the billet to accurately correct deviation or adapt to billets of different widths. In addition, for slab-shaped billets, the guide frame close to the billet can be removed to ensure that all types of billets enter the fan-shaped section smoothly and accurately, thus ensuring stable and efficient continuous casting operations.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0028] Example 1
[0029] Reference Figure 1-4 A cooling device, comprising:
[0030] The lower section 1 has four rectangular support columns 2 fixedly installed on its top. The tops of the four support columns 2 are then fixedly connected to the same upper section 3, thus constructing the main frame of the device and providing a foundation for the subsequent installation of various components and the realization of functions.
[0031] The guide assembly includes two support frames 13 symmetrically fixedly mounted on one side of the lower section 1. Each support frame 13 has two symmetrically formed grooves 14 on its top. Slide carriages 15 are slidably mounted in the two grooves 14 on the same support frame 13. Two guide frames 16 are slidably mounted on the top of the support frame 13. The two slide carriages 15 are fixedly connected to the bottom of the two guide frames 16, thereby achieving linkage between the guide frames 16 and the slide carriages 15. Furthermore, a double-outlet hydraulic cylinder 17 is embedded in each of the two support frames 13. The two piston ends of the double-outlet hydraulic cylinder 17 are fixedly connected to the two slide carriages 15 on the same support frame 13. Next, by controlling the extension and retraction of the piston of the double-outlet cylinder 17, the slide 15 can be driven to slide in the slide groove 14, thereby adjusting the position between the two guide frames 16. This can provide initial guidance for the entry of the billet to avoid deviation, and the position of the guide frames can be adjusted according to the actual position and size of the billet to accurately correct deviation or adapt to billets of different widths. The two guide frames 16 located on the same support frame 13 are T-shaped with the front larger than the back. This shape facilitates the entry of the billet. When it is necessary to guide the slab billet, the operator can remove one of the guide frames 16 that is close to each other on the two support frames 13 to adapt to the shape and size of the slab billet.
[0032] Multiple evenly distributed lower rollers 4 are rotatably mounted on the top of the lower section 1. A motor 12 is fixedly mounted on one side of the top of the lower section 1. The output shaft of the motor 12 is fixedly connected to one of the lower rollers 4. When the motor 12 starts, it can drive the lower roller 4 connected to it to rotate, and then drive the billet forward through friction.
[0033] A connecting frame 5 is slidably installed at the bottom of the upper forming section 3. Multiple upper rotating rollers 6 are evenly distributed and rotatably installed at the bottom of the connecting frame 5. A hydraulic cylinder 7 is embedded in the top of the upper forming section 3. The piston end of the hydraulic cylinder 7 is fixedly connected to the top of the connecting frame 5. By controlling the extension and retraction of the piston of the hydraulic cylinder 7, the connecting frame 5 can be driven to slide up and down, thereby adjusting the position of the upper rotating rollers 6 to meet the conveying requirements of billets of different thicknesses.

Multiple connecting pipes 9 are fixedly installed on both sides between the lower section 1 and the upper section 3. Two connecting pipes 9 on the same side are fixedly connected to the same connecting pipe 901. A connector is provided on one side of the connecting pipe 901 for connecting to an external water source. The cooling pipes 8 inside the lower section 1 and the upper section 3 are respectively connected to the corresponding connecting pipes 9 to form a cooling water circulation loop. The bottom of the lower section 1 and the upper section 3 are connected to the corresponding connecting pipes 9. Two fixed pipes 10 are symmetrically fixedly installed on the top of the upper section 3. Each fixed pipe 10 is fixedly connected to the corresponding cooling pipe 8. Each fixed pipe 10 is fixedly connected to a uniformly distributed spray pipe 11. One end of the multiple spray pipes 11 is fixedly connected to a water nozzle, and the multiple water nozzles are respectively facing the lower rotating roller 4 and the upper rotating roller 6. Cooling water enters the connecting pipe 901 through the connector, then flows into the connecting pipes 9 on both sides, and then enters the cooling pipe 8. Finally, part of the cooling water in the cooling pipe 8 flows into the fixed pipe 10, and then further flows into the spray pipe 11, and is sprayed out through the water nozzle to cool the surface of the billet.
