Description

Technical Field

[0001] This utility model relates to the technical field of detecting the combined effect of secondary cooling nozzles in continuous casting, specifically a device for detecting the combined effect of secondary cooling nozzles in continuous casting. Background Technology

[0002] The device with combined cooling nozzles in continuous casting refers to a device that uses two sets of cooling nozzles to cool the continuous casting. In the continuous casting process, the high-temperature molten steel is rapidly cooled in the crystallizer to form the initial billet shell. After the billet is pulled out of the crystallizer, it continues to be sprayed and cooled in the secondary cooling zone of continuous casting. The secondary cooling process is one of the core processes of continuous casting production. It determines the solidification process of the continuous casting billet and directly affects the quality of the continuous casting billet.

[0003] Based on existing solutions and actual production and processing applications, the current device for detecting the combined effect of secondary cooling nozzles in continuous casting still has some problems, such as:

[0004] 1. When testing the combined effect of secondary cooling nozzles in continuous casting, the method of staggering two adjacent rows of nozzles is often used to ensure the uniformity of cooling. However, under different pressures and water flow rates, the shape, area, and water volume of the overlapping spray areas of multiple nozzles are difficult to detect in production.

[0005] 2. In the process of using the combination of secondary cooling nozzles in continuous casting, the position of the cooling nozzles is relatively fixed, which leads to poor uniform cooling effect on the continuous casting. Therefore, this utility model provides a device for detecting the effect of the combination of secondary cooling nozzles in continuous casting to solve the above-mentioned problems. Utility Model Content

[0006] The purpose of this invention is to provide a device for detecting the combined effect of secondary cooling nozzles in continuous casting, so as to solve the problems mentioned in the background art, such as low detection efficiency of the shape and area of ​​the overlapping position of the nozzle spraying area under different pressures and water flow, and the fixed position of the cold nozzles and the small spraying area of ​​the cold nozzles leading to uneven cooling of the continuous casting.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a device for detecting the combined effect of secondary cooling nozzles in continuous casting, comprising a frame, a nozzle water pipe at the upper end of the frame, a pressure gauge fixedly installed at the right end of the nozzle water pipe, a pressure reducing valve inside the nozzle water pipe, a flow meter fixedly installed at the upper right end of the nozzle water pipe, and the right side of the flow meter connected to a water pump via a water pipe.

[0008] Also includes:

[0009] A water tank is fixedly installed inside the middle of the frame, and a partition is fixedly installed inside the water tank. A movable structure is movably connected to the upper middle of the frame.

[0010] A horizontal mounting bracket is movably mounted on the outside of the mounting structure, and an adjustment structure is connected to the inside of the horizontal mounting bracket.

[0011] Preferably, the movable structure includes a mounting plate installed on the outer side of the middle part of the frame, with rollers movably connected to the inner middle side of the mounting plate, and a movable rod movably connected to the outer side of the upper end of the mounting plate. A fixing plate is fixedly installed on the inner side of the upper end of the mounting plate, and a longitudinal support frame is fixedly connected to the inner side of the fixing plate.

[0012] Preferably, the mounting plate and the roller are rotatably connected, the vertical cross-section of the mounting plate is U-shaped, and the roller and the frame are connected by a fitting method.

[0013] Preferably, the mounting plate and the movable rod are connected by a thread, and the movable rod and the frame are connected by a fitted connection, which also limits the position of the mounting plate.

[0014] Preferably, a connecting plate that serves as a limiting element is movably connected to the lower outer side of the mounting plate, and a first spring is fixedly provided on the outer side of the middle part of the connecting plate, with a connecting rod passing through the middle of the first spring.

[0015] Preferably, the adjustment structure includes a mounting rod installed inside the rear side of the transverse mounting frame, and a movable plate is movably connected to the outer side of the mounting rod. The front side of the movable plate is fixedly connected to the rear side of the nozzle water pipe. A second spring is fixedly installed on the middle side of the front end of the transverse mounting frame, and a connecting rod that serves as a limit is connected through the middle of the second spring.

[0016] Preferably, the mounting rod and the transverse mounting frame are connected by rotation, and the mounting rod and the movable plate are connected by threads.

[0017] Preferably, the connecting plate and the connecting rod are slidably connected, and the connecting rod and the mounting plate are connected by a snap-fit ​​mechanism, and the connecting rods are symmetrically distributed about the center line of the connecting plate.

[0018] Compared with the prior art, the beneficial effects of this utility model are: the device for detecting the combined effect of the secondary cooling nozzles in continuous casting is equipped with a moving group to drive the nozzles to move, thereby adjusting the combination of the nozzles, and an adjusting structure to drive the nozzles to move up and down, so that the nozzles are closer to or further away from the top of the water tank, thereby adjusting the distance between the nozzles and the water tank.

[0019] 1. By snapping the mounting plate onto the upper middle side of the frame, and then installing the connecting plate onto the lower middle side of the roller, the connecting plate is snapped onto the lower outer side of the mounting plate. The connecting rod is then released, causing the first spring to slide the connecting rod inward, thereby allowing the connecting rod to slide inward in the middle of the connecting plate. This allows the connecting rod to snap onto the lower outer side of the flow meter, facilitating the installation of the mounting plate and thus the installation of the longitudinal support frame.

[0020] 2. By pulling the connecting rod forward, the connecting rod slides forward on the front side of the middle of the transverse mounting frame, thereby causing the connecting rod to drive the second spring to extend. This causes the second spring to separate on the front side of the longitudinal support frame. Then, push the transverse mounting frame to slide it to the appropriate position on the outside of the longitudinal support frame. Release the connecting rod, and the second spring causes the connecting rod to slide backward on the middle of the transverse mounting frame, thereby causing the connecting rod to abut against the front side of the longitudinal support frame. This facilitates the movement of the nozzle water pipe and allows for easy adjustment of the nozzle water pipe combination.

[0021] 3. By rotating the mounting rod, the mounting rod rotates inside the rear side of the horizontal mounting frame, causing the moving plate, which is threadedly connected to the mounting rod, to slide up and down. This causes the moving plate to move the nozzle water pipe up and down in the middle of the horizontal mounting frame, making it convenient to adjust the height of the nozzle water pipe.

[0029] 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.

[0030] Please see Figure 1-6 This utility model provides a technical solution: a device for detecting the combined effect of secondary cooling nozzles in continuous casting, comprising: a frame 1, a water tank 2, a moving plate 3, a nozzle water pipe 4, a flow meter 5, a pressure gauge 6, a partition 7, a mounting plate 8, a longitudinal support frame 9, a pressure reducing valve 10, a transverse mounting frame 11, a mounting rod 12, a fixing plate 13, a roller 14, a moving rod 15, a connecting plate 16, a first spring 17, a connecting rod 18, a second spring 19, and a connecting rod 20. In operation, the specific details are as follows... Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, a mounting plate 8 is movably connected to the outer side of the middle of frame 1, and a connecting plate 16 is movably installed on the outer side of the lower end of mounting plate 8. A first spring 17 is fixedly installed on the outer side of connecting plate 16. The mounting plate 8 is manually placed on the upper middle side of frame 1, so that under manual action, mounting plate 8 is engaged and installed on the upper middle side of frame 1. Then, the connecting rod 18 is manually pulled outward, so that under manual action, connecting rod 18 moves outward from the outer side of the middle of connecting plate 16. The movement of connecting rod 18 causes the first spring 17 to extend, allowing the connecting plate 16 to be manually engaged. Plate 16 is installed on the lower middle side of frame 1, so that when manually operated, connecting plate 16 is engaged on the lower outer side of mounting plate 8. Manually releasing connecting rod 18 causes the first spring 17 to slide inward under the elastic action of the first spring 17. As a result, the connecting rod 18 slides inward in the middle of connecting plate 16 under the action of the movement of connecting rod 18. Then, the connecting plate 16 is engaged on the lower outer side of mounting plate 8 under the action of the movement of connecting rod 18, which facilitates the installation of mounting plate 8 and thus facilitates the installation of longitudinal support frame 9.

[0031] Specific examples Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, a roller 14 is movably mounted on the upper side of the mounting plate 8, and a movable rod 15 is movably connected to the outer side of the upper end of the mounting plate 8. Twisting the movable rod 15 causes it to be threaded onto the outer side of the upper end of the mounting plate 8. The threaded action between the movable rod 15 and the mounting plate 8 causes the movable rod 15 to slide outwards. This outward movement separates the movable rod 15 from the outer side of the frame 1. Manually pushing the mounting plate 8 causes it to move back and forth on the outer side of the frame 1. This movement causes the frame 1 to push the roller 14 to rotate inside the mounting plate 8. This movement of the mounting plate 8 then causes the mounting plate 8 to move the fixed plate 13 back and forth. The movement causes the fixed plate 13 to move the longitudinal support frame 9, which in turn causes the longitudinal support frame 9 to move the transverse mounting frame 11 back and forth. This movement of the transverse mounting frame 11 causes the nozzle water pipe 4 to move. Once the nozzle water pipe 4 is in the appropriate position, the moving rod 15 is tightened. This tightening action causes the moving rod 15 to be threaded onto the outer side of the upper end of the mounting plate 8. The thread action between the moving rod 15 and the mounting plate 8 causes the moving rod 15 to slide inward at the lower end of the mounting plate 8. This movement causes the moving rod 15 to fit against the outer side of the frame 1, thus holding the mounting plate 8 in place and facilitating the adjustment of the nozzle water pipe 4's position.

[0032] Specific examples Figure 1 , Figure 5 and Figure 6As shown, a transverse mounting bracket 11 is movably connected to the outer side of the longitudinal support frame 9. A second spring 19 is fixedly installed at the middle of the front end of the transverse mounting bracket 11. A connecting rod 20 is connected through the middle of the second spring 19. Manually pulling the connecting rod 20 forward causes it to slide forward at the middle of the front end of the transverse mounting bracket 11. This movement of the connecting rod 20 causes the second spring 19 to extend. Then, manually pushing the transverse mounting bracket 11 causes it to move left and right on the outer side of the longitudinal support frame 9. This causes the transverse mounting bracket 11 to move the nozzle water pipe 4 to the appropriate position. Releasing the connecting rod 20 allows it to slide backward at the middle of the transverse mounting bracket 11 under the elastic action of the second spring 19. Under the sliding action, the connecting rod 20 is attached to the front side of the longitudinal support frame 9, thereby abutting the longitudinal support frame 9 and facilitating the limiting of the transverse mounting frame 11. This allows for easy left and right adjustment of the position of the nozzle water pipe 4. The combination of the nozzle water pipe 4 can be adjusted by adjusting the longitudinal support frame 9 and the transverse mounting frame 11. The water flow density under the combined action of the nozzle water pipe 4 can be calculated by converting the water level readings at different intervals based on the partition 7 set inside the water tank 2. The smaller the water level difference within the interval of the water tank 2 in the spray area, the higher the cooling uniformity of the nozzle combination. It is possible to detect various state parameters of nozzles with different combinations, thereby measuring the shape, size, and spray water volume of the spray superposition area of ​​each nozzle, ensuring that the spray water volume is evenly distributed when the nozzle combination is used, thus ensuring uniform cooling of the billet and ultimately improving the quality of the continuously cast billet.

[0033] Specific examples Figure 1 , Figure 3 , Figure 5 and Figure 6 As shown, a mounting rod 12 is movably connected to the rear side of the interior of the transverse mounting frame 11, and a movable plate 3 is movably connected to the outer side of the mounting rod 12. The outer side of the movable plate 3 is fixedly connected to the outer side of the nozzle water pipe 4. The mounting rod 12, which is installed on the rear side of the interior of the transverse mounting frame 11, is manually rotated. Under manual action, the mounting rod 12 rotates on the rear side of the interior of the transverse mounting frame 11. Under the action of the rotation of the mounting rod 12, the mounting rod 12 is threadedly connected to the rear side of the movable plate 3. Then, under the action of the thread between the mounting rod 12 and the movable plate 3, the movable plate 3 moves downward. Under the action of the downward movement of the movable plate 3, the movable plate 3 drives the nozzle water pipe 4 to slide downward in the middle of the transverse mounting frame 11. This facilitates the up and down movement of the nozzle water pipe 4, so that it can move closer to or away from the upper opening of the water tank 2. Then, the water pump set on the right side of the flow meter 5 draws water into the interior of the nozzle water pipe 4. The pressure gauge 6 and the pressure reducing valve 10 set on the upper side of the nozzle water pipe 4 can easily reduce the water pressure and detect the water pressure.
