Description

Technical Field

[0001] This application relates to the field of steel cooling technology, and in particular to a nozzle arrangement structure in a dynamic secondary cooling control system. Background Technology

[0002] Continuous casting technology, as one of the core processes in the steel industry, plays a crucial role in improving production efficiency and product quality. Especially in the automotive, shipbuilding, construction, and machinery manufacturing sectors, the increasing demands for the internal quality and performance of steel have driven the continuous advancement of continuous casting technology. Secondary cooling is a critical part of the continuous casting process, directly affecting the quality characteristics of the cast billet. To meet the demands of high casting speeds and diverse steel grades, precise control of the secondary cooling water flow has become an important means of optimizing billet quality.

[0003] Currently, the main methods for achieving water flow distribution in secondary cooling systems include fixed nozzle layouts and simple mechanical adjustment devices. Fixed nozzle layouts complete the cooling operation by installing nozzles in preset positions; while simple mechanical adjustment devices improve the cooling effect by manually or unidirectionally adjusting the position of some nozzles.

[0004] However, the nozzle position in the above-mentioned method lacks sufficient flexibility, resulting in poor adjustability of the nozzle setting position. This leads to obvious shortcomings when facing rapidly changing production process conditions, making it impossible to accurately match the optimal cooling strategy required for different types of steel. Consequently, the control precision is low, the adaptability is limited, and the possibility of further improving the quality of the cast billet is restricted.

[0005] The aforementioned technologies suffer from insufficient adjustability of the secondary cooling water flow nozzles. Utility Model Content

[0006] To improve the adjustability of the secondary cooling water flow nozzles, this application provides a nozzle arrangement structure in a dynamic secondary cooling control system.

[0007] The nozzle arrangement structure in the dynamic secondary cooling control system provided in this application adopts the following technical solution:

[0008] A nozzle arrangement structure in a dynamic secondary cooling control system includes: a support mechanism comprising a support frame and a support plate, the support plate being connected to the support frame and mounted above the workpiece; a first adjustment mechanism comprising a drive group, a first moving member, and a second moving member, the drive group comprising a first drive member, a bidirectional lead screw, a first lead screw nut, and a second lead screw nut, the first drive member being connected to the side of the support plate near the workpiece, one end of the bidirectional lead screw being drively connected to the output end of the first drive member, and the other end of the bidirectional lead screw being rotatably connected to the support plate, the first lead screw nut and the second lead screw nut being screwed onto the bidirectional lead screw, allowing the first lead screw nut and the second lead screw nut to move towards or away from each other, one end of the first moving member being connected to the first lead screw nut, the other end of the first moving member being able to slide relative to the support plate, and one end of the second moving member being connected to the second lead screw nut. The other end of the second moving member can slide relative to the support plate, allowing the first moving member and the second moving member to move towards or away from each other; a first water spraying mechanism includes a first hinge rod, a second hinge rod, a first nozzle, and a plurality of second nozzles. The first end of the first hinge rod is hinged to the first moving member, the first end of the second hinge rod is hinged to the second moving member, the second ends of the first hinge rod and the second ends of the second hinge rod are hinged together, the first nozzle is located at the second end of the first hinge rod or the second end of the second hinge rod, and the plurality of second nozzles are evenly distributed on the first hinge rod and the second hinge rod, making the direction of the connecting line between the first nozzle and the second nozzle adjustable; the control mechanism includes a temperature measuring component and a controller. The temperature measuring component is used to measure the temperature of the workpiece, and the temperature measuring component and the first adjustment mechanism are both electrically connected to the controller.

[0009] By adopting the above technical solution, the flexibility and precision of the nozzle arrangement structure are achieved. Specifically: the design of the support mechanism ensures the stability of the entire structure, allowing the first water spraying mechanism to be positioned above the workpiece; the first adjustment mechanism utilizes the cooperation of a bidirectional lead screw, a first nut, and a second nut to achieve the opposing or divergent movements of the first and second moving parts, thereby adjusting the overall posture and coverage of the first water spraying mechanism and improving the controllability and adaptability of the cooling area; the design of multiple nozzles and the hinge method in the first water spraying mechanism make the direction of the connecting line between the first and second nozzles adjustable, thus meeting the cooling requirements under different working conditions. This design, through the adjustment of the first water spraying mechanism by the first adjustment mechanism, makes the positions of the first and second nozzles dynamically adjustable, thereby enabling the controller to control the action of the first adjustment mechanism based on the temperature measurement of the workpiece by the temperature measuring component, significantly improving the cooling effect and control accuracy of the secondary cooling system, and enhancing the system's adaptability to changing production conditions and high-quality requirements.

[0010] Optionally, the second nozzle includes a connecting part, a rotary joint, and a nozzle part. One end of the connecting part is connected to a water pipe, the other end of the connecting part is connected to one end of the rotary joint, the other end of the rotary joint is connected to the nozzle part, and the outlet of the nozzle part is a flat opening.

[0011] By adopting the above technical solution, flexible installation and precise positioning of the second nozzle are achieved. The flat-mouth design of the nozzle part can form a more uniform water flow with a larger coverage area, effectively improving cooling efficiency and the quality stability of the billet surface; the design of the connecting part and the rotary joint allows the nozzle to be freely adjusted within a certain range, thereby better adapting to different cooling requirements; this structural improvement can significantly improve the adaptability and cooling effect of the secondary cooling system, meeting the requirements of high-precision cooling processes.

[0012] Optionally, the first nozzle and the second nozzle have the same structure.

[0013] By adopting the above technical solution, the identical structure of the first and second nozzles makes the design of the entire nozzle arrangement structure more unified and modular, which is convenient for production and maintenance. In addition, the identical structure ensures that each nozzle has similar performance under similar working conditions, which helps to achieve a more uniform and stable cooling effect, thereby improving the quality consistency of the cast billet.

[0014] Optionally, it also includes a second water spraying mechanism, the two ends of which are respectively connected to the first moving member and the second moving member, and the second water spraying mechanism has the same structure as the first water spraying mechanism.

[0015] By adopting the above technical solution, a second water spray mechanism is added to the dynamic secondary cooling control system. On the one hand, the spray coverage and the uniformity of the cooling effect are improved; on the other hand, the cooling water volume can be increased as needed through the second water spray mechanism to meet the cooling requirements under different working conditions.

[0016] Optionally, it further includes a second adjustment mechanism, which includes a first sliding block and a second sliding block. The first sliding block is slidably connected to the first moving member, and the second sliding block is slidably connected to the second moving member. The two ends of the second water spraying mechanism are respectively connected to the first sliding block and the second sliding block, so that the horizontal distance between the second water spraying mechanism and the first water spraying mechanism is adjustable.

[0017] By adopting the above technical solution, the horizontal distance between the second water spraying mechanism and the first water spraying mechanism can be flexibly adjusted. Specifically, the first sliding block and the second sliding block are slidably connected to the first moving part and the second moving part, respectively, so that the position of the second water spraying mechanism can be adjusted according to actual needs, thereby optimizing the nozzle layout to adapt to different workpiece sizes and cooling requirements. This adjustability improves the applicability and flexibility of the system, ensures precise control of the cooling process, and thus helps to improve the quality stability of the cast billet.

[0018] Optionally, the second adjustment mechanism includes a second driving member, the two ends of which are respectively connected to the first water spraying mechanism and the second water spraying mechanism, and the second driving member is used to adjust the distance between the first water spraying mechanism and the second water spraying mechanism.

[0019] By adopting the above technical solution, precise adjustment of the distance between the first and second water spraying mechanisms can be achieved. Specifically, the first and second water spraying mechanisms are connected to each other at both ends of the second driving component, allowing operators to flexibly adjust their relative positions according to actual needs, thereby optimizing the distribution range and coverage density of the cooling water. This design effectively improves the system's adaptability to workpieces of different sizes and diverse cooling process requirements, thereby improving the quality stability and production efficiency of the cast billet.

[0020] Optionally, it further includes a first fixed block and a second fixed block, the first fixed block being connected to the first moving member, the second fixed block being connected to the second moving member, the first end of the first hinge rod of the first water spraying mechanism being hinged to the first fixed block, the first end of the second hinge rod of the first water spraying mechanism being hinged to the second fixed block, and two second driving members being provided, the fixed ends of the two second driving members being respectively connected to the first fixed block and the second fixed block, and the telescopic ends of the two second driving members being respectively connected to the first sliding block and the second sliding block.

[0021] By adopting the above technical solution, the addition of the first and second fixed blocks makes the hinge of the first water spraying mechanism more stable, improving the accuracy and stability of nozzle position adjustment. Two second driving components connect the first fixed block and the first sliding block, and the second fixed block and the second sliding block, respectively, enabling precise control of the distance between the first and second water spraying mechanisms, further enhancing the system's adaptability to different cooling requirements. This design effectively improves the flexibility and control precision of the secondary cooling system, thereby improving the cooling uniformity of the cast billet and contributing to improved product quality.

[0022] Optionally, it also includes a support bracket, the upper end of which is connected to the support plate, and the lower end of which is used to support the first water spraying mechanism and the second water spraying mechanism.

[0023] By adopting the above technical solution, the support frame effectively enhances the stability of the first and second water spraying mechanisms, preventing swaying or displacement caused by water flow impact, thereby ensuring the accuracy and reliability of the nozzle arrangement structure during operation. Specifically, the design of the support frame connecting the upper end to the support plate and supporting the water spraying mechanism at the lower end gives the entire system better load-bearing capacity and vibration resistance, further improving the cooling effect of the secondary cooling control system and the consistency of the billet quality.

[0024] Optionally, it further includes a third adjustment mechanism, which includes a third driving member and a connecting plate. The fixed end of the third driving member is connected to the support frame, and the telescopic end of the third driving member is connected to the connecting plate. The connecting plate is connected to the support plate.

[0025] By adopting the above technical solution, the third adjustment mechanism can achieve height adjustment of the support plate. Specifically, the telescopic movement of the third driving component drives the connecting plate to move up and down, thereby adjusting the position of the support plate. This design allows the entire nozzle arrangement structure to flexibly adapt to workpieces of different specifications or different cooling requirements, improving the system's versatility and applicability.

[0026] Optionally, the drive group is provided in two sets, with the two sets of drive groups respectively connected to the two ends of the first moving member and the two sets of drive groups respectively connected to the two ends of the second moving member, so that the first moving member and the second moving member can move towards each other or away from each other.

[0027] By adopting the above technical solution, the arrangement of two sets of drive groups allows the first and second moving parts to be simultaneously driven at both ends, thereby achieving smoother and more precise opposite or opposite movements. This design effectively improves the adjustment accuracy and stability of the nozzle arrangement structure, ensuring that cooling water can more evenly cover the workpiece surface, thus improving the internal quality of the cast billet and production efficiency.

[0028] In summary, this application includes at least one of the following beneficial technical effects:

[0029] 1. Through the cooperation of the support mechanism and the first adjustment mechanism, the nozzle position can be precisely adjusted, and the cooling water flow distribution can be flexibly adjusted according to different production process conditions, which significantly improves the system's adaptability and control accuracy;

[0030] 2. The design of the first water spraying mechanism makes the direction of the connecting line between the first nozzle and the second nozzle adjustable, which can better match the optimal cooling position required by different steel grades and effectively improve the internal quality of the billet.

[0031] 3. The nozzle structure is reasonably designed, especially the application of the flat outlet, which enhances the uniformity of cooling effect and reduces the risk of product defects caused by uneven cooling. Attached Figure Description

[0038] The following is in conjunction with the appendix Figure 1 - Appendix Figure 4 This application will be further described in detail below. In this embodiment, unless otherwise specified, "connection", "linking", and "fixing" are interpreted broadly, including fixed connection, detachable connection, connection to form an integral structure, mechanical connection, electrical connection, direct connection, indirect connection through an intermediary, internal connection, and interaction between two components, etc., and can be understood according to the specific circumstances.

[0039] In this application, unless otherwise expressly specified and limited, "above" or "below" a second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, in the description of this embodiment, terms such as "above," "below," "left," and "right," etc., are based on the orientation or positional relationships shown in the accompanying drawings and are used only for ease of description and simplification of operation. They do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application. Unless otherwise stated, directional terms such as "inner" and "outer" used in this application refer to the outline of the corresponding component itself.

[0040] like Figure 1 , Figure 2 and Figure 3 As shown in the embodiment of this application, a nozzle arrangement structure (hereinafter referred to as "arrangement structure") in a dynamic secondary cooling control system is disclosed. This arrangement structure includes a support mechanism 1, a first adjustment mechanism 2, a first water spraying mechanism 3, and a control mechanism, used to improve the flexibility and precision of the nozzle arrangement structure, thereby optimizing the secondary cooling effect on workpieces such as the casting billet 200 on the conveying mechanism 100. The conveying mechanism 100 can be selected from suitable existing structures as needed for conveying the casting billet 200.

[0041] The design of the support mechanism 1 ensures the stability of the entire structure. The support mechanism 1 includes a support frame 11 and a support plate 12. The support plate 12 is connected to the support frame 11 and is mounted above the workpiece so that the first water spraying mechanism 3 can be located above the workpiece.

[0042] like Figure 1 , Figure 2 and Figure 3As shown, the first adjustment mechanism 2 includes a drive group 21, a first moving member 22, and a second moving member 23. The drive group 21 includes a first drive member 211, a bidirectional lead screw 212, a first lead screw nut 213, and a second lead screw nut 214. The first drive member 211 is connected to the side of the support plate 12 near the workpiece. One end of the bidirectional lead screw 212 is connected to the output end of the first drive member 211, and the other end of the bidirectional lead screw 212 is rotatably connected to the support plate 12. The first lead screw nut 213 and the second lead screw nut 214 are both screwed onto the bidirectional lead screw 212, allowing the first lead screw nut 213 and the second lead screw nut 214 to move towards or away from each other. The first moving member 22 and the second moving member 23 are parallel to each other. One end of the first moving member 22 is connected to the first lead screw nut 213, and the other end of the first moving member 22 can slide relative to the support plate 12. One end of the second moving member 23 is connected to the second lead screw nut 214, and the other end of the second moving member 23 can slide relative to the support plate 12, allowing the first moving member 22 and the second moving member 23 to move towards or away from each other. In this embodiment, both the first moving member 22 and the second moving member 23 are straight rod structures.

[0043] The first water spraying mechanism 3 includes a first hinge rod 31, a second hinge rod 32, a first nozzle 33, and a plurality of second nozzles 34. The first end of the first hinge rod 31 is hinged to a first moving member 22, the first end of the second hinge rod 32 is hinged to a second moving member 23, and the second ends of the first hinge rod 31 and the second ends of the second hinge rod 32 are hinged together. The first nozzle 33 is located at the hinge point of the second end of the first hinge rod 31 or the second end of the second hinge rod 32. The plurality of second nozzles 34 are evenly distributed on the first hinge rod 31 and the second hinge rod 32. In this embodiment, a second nozzle 34 is provided on each of the first hinge rod 31 and the second hinge rod 32. The direction of the connecting line between the first nozzle 33 and one of the second nozzles 34 can be adjusted by the relative rotation of the first hinge rod 31 and the second hinge rod 32.

[0044] like Figure 1 , Figure 2 and Figure 3 As shown, the control mechanism includes a temperature measuring component and a controller. The temperature measuring component is used to measure the temperature of the workpiece, and both the temperature measuring component and the first adjustment mechanism 2 are electrically connected to the controller. The temperature measuring component may include multiple temperature probes or temperature sensors distributed at different locations to obtain the temperature at different locations of the casting billet 200. The temperature data from the temperature measuring component is used to send an electrical signal to the controller, thereby causing the controller to control the first adjustment mechanism 2 to operate, enabling the first water spraying mechanism 3 to operate accordingly and adjust the distribution of the first nozzle 33 and the second nozzle 34. The controller can be selected from suitable existing structures as needed, such as a microcontroller or computer with built-in programs.

[0045] The first driving component 211 drives the bidirectional lead screw 212 to rotate, thereby causing the first nut 213 and the second nut 214 screwed onto it to move towards or away from each other, which in turn drives the first moving component 22 and the second moving component 23 to adjust their positions synchronously. The first adjusting mechanism 2 utilizes the cooperation of the bidirectional lead screw 212, the first nut 213 and the second nut 214 to realize the opposite or opposite movement of the first moving component 22 and the second moving component 23, thereby adjusting the overall posture and coverage of the first water spray mechanism 3, improving the controllability and adaptability of the cooling area, so that the higher temperature areas can be cooled better. The design of multiple nozzles and the hinge method in the first water spray mechanism 3 make the direction of the connecting line of the first nozzle 33 and the second nozzle 34 adjustable, thereby meeting the cooling requirements under different working conditions. This design, through the adjustment action of the first adjusting mechanism 2 on the first water spray mechanism 3, makes the positions of the first nozzle 33 and the second nozzle 34 dynamically adjustable, significantly improving the cooling effect and control accuracy of the secondary cooling system, and enhancing the system's adaptability to changing production conditions and high-quality requirements.

[0046] like Figure 1 , Figure 2 and Figure 3 As shown, optionally, the drive group 21 is provided in two groups, the two drive groups 21 are respectively connected to the two ends of the first moving member 22, and the two drive groups 21 are respectively connected to the two ends of the second moving member 23, so that the first moving member 22 and the second moving member 23 can move towards each other or away from each other.

[0047] The arrangement of two sets of drive groups 21 allows both the first moving part 22 and the second moving part 23 to be simultaneously driven at both ends, thereby achieving smoother and more precise opposite or opposite movements. This design effectively improves the adjustment accuracy and stability of the nozzle arrangement structure, ensuring that cooling water can more evenly cover the workpiece surface, thus improving the internal quality and production efficiency of the casting 200. The first drive member 211 can be a motor; the bidirectional lead screw 212 refers to the screw with opposite threads at both ends, and the first nut 213 and the second nut 214 are screwed into threads with opposite directions so that the movement directions of the first nut 213 and the second nut 214 are opposite. A suitable existing structure can be selected as needed.

[0048] like Figure 1 , Figure 3 and Figure 4As shown, optionally, the second nozzle 34 includes a connecting part 341, a rotary joint 342, and a nozzle part 343. One end of the connecting part 341 is connected to a water pipe, allowing for easy connection and ensuring a stable water supply. The other end of the connecting part 341 is connected to one end of the rotary joint 342, and the other end of the rotary joint 342 is connected to the nozzle part 343. The design of the connecting part 341 and the rotary joint 342 allows the nozzle to freely adjust its angle within a certain range, thus better adapting to different cooling requirements. The outlet of the nozzle part 343 is a flat opening, which can form a more uniform water flow with a larger coverage area, effectively improving cooling efficiency and the surface quality stability of the billet 200. Furthermore, because the outlet of the nozzle part 343 is designed as a flat opening, it can form a more concentrated water flow impact area during actual use, improving cooling efficiency while avoiding the problem of excessively dispersed water flow that may occur with traditional circular outlets. This structure not only improves the cooling effect but also enhances the system's adaptability to different workpiece sizes and shapes.

[0049] Optionally, the first nozzle 33 and the second nozzle 34 have the same structure, making the design of the entire nozzle arrangement more unified and modular, which facilitates production and maintenance. In addition, the identical structure ensures that each nozzle has similar performance under similar working conditions, which helps to achieve a more uniform and stable cooling effect, thereby improving the quality consistency of the cast billet 200.

[0050] like Figure 1 , Figure 2 and Figure 3 As shown, optionally, this arrangement also includes a second water spray mechanism 4. The two ends of the second water spray mechanism 4 are respectively connected to the first moving part 22 and the second moving part 23, and the structure of the second water spray mechanism 4 is the same as that of the first water spray mechanism 3. Adding a second water spray mechanism 4 to the dynamic secondary cooling control system improves the spray coverage and the uniformity of the cooling effect; furthermore, when the temperature displayed by the temperature measuring component is too high, the second water spray mechanism 4 can increase the cooling water volume as needed to meet the cooling requirements under different operating conditions.

[0051] Optionally, the arrangement structure also includes a support frame 7. The upper end of the support frame 7 is connected to the support plate 12, and the lower end of the support frame 7 is used to support the first water spraying mechanism 3 and the second water spraying mechanism 4. The support frame 7 can effectively enhance the stability of the first water spraying mechanism 3 and the second water spraying mechanism 4, avoid shaking or displacement caused by water flow impact, and thus ensure the accuracy and reliability of the nozzle arrangement structure during operation. Specifically, the design of the upper end of the support frame 7 being connected to the support plate 12 and the lower end supporting the first water spraying mechanism 3 and the second water spraying mechanism 4 effectively distributes the working load of the first water spraying mechanism 3 and the second water spraying mechanism 4, avoids structural deformation or damage caused by long-term high-pressure water flow impact, and makes the entire system have better load capacity and vibration resistance, further improving the cooling effect of the secondary cooling control system and the quality consistency of the billet 200. At the same time, during installation and maintenance, the support frame 7 can provide additional support force to ensure that the first water spraying mechanism 3 and the second water spraying mechanism 4 always maintain precise position and angle, thereby ensuring uniform distribution of cooling water and efficient cooling effect.

[0052] like Figure 1 , Figure 2 and Figure 3 As shown, optionally, this arrangement structure also includes a second adjustment mechanism 5, which includes a first sliding block 51 and a second sliding block 52. The first sliding block 51 is slidably connected to the first moving member 22, and the second sliding block 52 is slidably connected to the second moving member 23. The two ends of the second water spraying mechanism 4 are respectively connected to the first sliding block 51 and the second sliding block 52, so that the horizontal distance between the second water spraying mechanism 4 and the first water spraying mechanism 3 is adjustable, which helps to optimize the nozzle layout to adapt to different workpiece sizes and cooling requirements.

[0053] When it is necessary to change the horizontal distance between the second water spraying mechanism 4 and the first water spraying mechanism 3, the first sliding block 51 and the second sliding block 52 can be slid to adapt to different cooling requirements. Specifically, in actual operation, based on the temperature measurement of the temperature measuring component, the nozzle layout can be optimized in real time by the first adjusting mechanism 2 according to the changes in the width, shape, and required cooling intensity of the billet 200, ensuring accurate coverage of the cooling water flow, improving cooling efficiency, and guaranteeing the quality stability of the billet 200.

[0054] like Figure 1 , Figure 2 and Figure 3As shown, optionally, the second adjustment mechanism 5 includes a second driving member 53, with its two ends connected to the first water spraying mechanism 3 and the second water spraying mechanism 4, respectively. The second driving member 53 is used to adjust the distance between the first water spraying mechanism 3 and the second water spraying mechanism 4. Specifically, by connecting the two ends of the second driving member 53 to the first water spraying mechanism 3 and the second water spraying mechanism 4, the operator can flexibly adjust the relative position between them according to actual needs such as the temperature measurement results of the temperature measuring component, thereby optimizing the distribution range and coverage density of the cooling water. This design effectively improves the system's adaptability to workpieces of different sizes and diverse cooling process requirements, thereby improving the quality stability and production efficiency of the cast billet 200. The second driving member 53 can be a cylinder, hydraulic cylinder, or electric telescopic rod, or other structure capable of extension and retraction.

[0055] like Figure 1 , Figure 2 and Figure 3 As shown, optionally, this arrangement structure further includes a first fixing block 61 and a second fixing block 62. The first fixing block 61 is connected to the first moving member 22, and the second fixing block 62 is connected to the second moving member 23. The first end of the first hinge rod 31 of the first water spraying mechanism 3 is hinged to the first fixing block 61, and the first end of the second hinge rod 32 of the first water spraying mechanism 3 is hinged to the second fixing block 62. Two second driving members 53 are provided. The fixed ends of the two second driving members 53 are respectively connected to the first fixing block 61 and the second fixing block 62, and the telescopic ends of the two second driving members 53 are respectively connected to the first sliding block 51 and the second sliding block 52.

[0056] The addition of the first fixing block 61 and the second fixing block 62 makes the hinge of the first water spraying mechanism 3 more stable, improving the accuracy and stability of nozzle position adjustment. The two second driving components 53 connect the first fixing block 61 and the first sliding block 51, and the second fixing block 62 and the second sliding block 52, respectively, enabling precise control of the distance between the first water spraying mechanism 3 and the second water spraying mechanism 4, further enhancing the system's adaptability to different cooling requirements. This design effectively improves the flexibility and control precision of the secondary cooling system, thereby improving the cooling uniformity of the billet 200 and contributing to improved product quality.

[0057] like Figure 1 , Figure 2 and Figure 3As shown, optionally, the arrangement structure also includes a third adjustment mechanism 8, which includes a third drive member 81 and a connecting plate 82. The fixed end of the third drive member 81 is connected to the support frame 11, and the telescopic end of the third drive member 81 is connected to the connecting plate 82. The connecting plate 82 is connected to the support plate 12, and the connecting plate 82 and the support plate 12 are vertically spaced apart. The third adjustment mechanism 8 can adjust the height of the support plate 12. Specifically, the telescopic movement of the third drive member 81 drives the connecting plate 82 to move up and down, thereby adjusting the position of the support plate 12. This design allows the entire nozzle arrangement structure to flexibly adapt to workpieces of different specifications or different cooling requirements, improving the versatility and applicability of the system. The third drive member 81 can be a cylinder, hydraulic cylinder, or electric telescopic rod, etc., capable of telescopic movement. Depending on the usage requirements, the first drive member 211, the second drive member 53, and the third drive member 81 can all be electrically connected to a controller so that the adjustment of the arrangement structure can be performed automatically; alternatively, the first drive member 211, the second drive member 53, and the third drive member 81 can be manually controlled according to the actual situation to improve control reliability.

[0058] It is understandable that the arrangement structure also includes necessary structures for connection, support, drive, positioning, limiting, sealing and control functions, so that the arrangement structure can operate normally; the shape, size, material and quantity of each part of the arrangement structure can be determined as needed, as long as the corresponding functions can be achieved.

[0059] The implementation principle of the nozzle arrangement structure in the dynamic secondary cooling control system of this application embodiment is as follows: the support mechanism 1 enables the first water spraying mechanism 3 to be located above the workpiece. The design of multiple nozzles in the first water spraying mechanism 3 and the hinge method make the direction of the connecting line where the first nozzle 33 and the second nozzle 34 are located adjustable. The first adjustment mechanism 2 uses the cooperation of the bidirectional lead screw 212, the first lead screw nut 213 and the second lead screw nut 214 to realize the opposite or opposite movement of the first moving part 22 and the second moving part 23. In this way, the overall posture and coverage of the first water spraying mechanism 3 can be adjusted according to the comparison between the temperature measurement result of the temperature measuring component and the required result, thereby improving the controllability and adaptability of the cooling area and meeting the cooling requirements under different working conditions.

[0060] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
