TECHNICAL FIELD

[0001] The application relates to a cooling device in steel processing, in particular to a secondary cooling water flow control device in a dynamic secondary cooling control system. BACKGROUND

[0002] Continuous casting technology is one of the core processes in modern steel industry, and plays an important role in improving production efficiency and product quality. Especially in the automobile, shipbuilding, construction and machinery manufacturing industries, the demand for high-quality steel is growing, which makes the research on the key link in the continuous casting process, namely the secondary cooling (referred to as two cooling), particularly important. Through accurate and effective cooling treatment of the casting blank, the microstructure of the steel can be improved, thereby optimizing its mechanical properties and prolonging its service life.

[0003] At present, the secondary cooling of the casting blank is usually simply set by relying on artificial experience to set fixed water flow parameters, and the water flow remains unchanged during the entire pouring period.

[0004] However, in actual application, the existing measures generally lack precision due to excessive reliance on personal judgment, and have strong rigidity and low adaptability in the face of special needs of different types of steel, and the adjustability of the water flow in the cooling process is poor.

[0005] In the above related technology, the casting blank secondary cooling process has the defect of poor adjustability of the cooling water flow. CONTENT OF THE INVENTION

[0025] By adopting the above technical scheme, the hooking mechanism can effectively manage the position change of the flexible pipe. Specifically, during the process that the auxiliary water spraying mechanism approaches the main water spraying mechanism, horizontal movement of the pushing member drives vertical displacement of the sliding member by cooperation of the first inclined surface and the second inclined surface.

Unless otherwise stated, the orientation words used in the present application, such as "inner" and "outer", refer to the outline of the corresponding parts.

[0048] As shown in Figure 1 , Figure 2 and Figure 3 , the present embodiment discloses a secondary cooling water flow control device in a dynamic secondary cooling control system (hereinafter referred to as "device"), which comprises a supporting mechanism 1, a water conveying mechanism 2, a main water spraying mechanism 3, an auxiliary water spraying mechanism 4, a moving mechanism 5, a temperature measuring mechanism and a control mechanism, which can optimize the secondary cooling effect of the workpiece such as the cast slab of the steel material.

[0049] As shown in Figure 1 , Figure 2 and Figure 4 , the supporting mechanism 1 comprises a supporting plate 11 and a plurality of supporting columns 12, the supporting columns 12 are distributed on the lower surface of the supporting plate 11, so that the supporting plate 11 can be erected above the workpiece. The supporting mechanism 1 ensures that the entire device is stably erected above the workpiece, and provides a stable installation basis for the main water spraying mechanism 3 and the auxiliary water spraying mechanism 4, so that the workpiece can be sprayed and cooled. The main water spraying mechanism 3 is arranged on the lower side of the supporting plate 11, and the main water spraying mechanism 3 is connected to the water conveying mechanism 2 for spraying water to the workpiece. The auxiliary water spraying mechanism 4 is arranged on the lower side of the supporting plate 11, and the auxiliary water spraying mechanism 4 is arranged on one side of the main water spraying mechanism 3, and the auxiliary water spraying mechanism 4 is arranged on the side of the main water spraying mechanism 3 away from the water conveying mechanism 2, that is, along the conveying direction of the workpiece, the auxiliary water spraying mechanism 4 is arranged at the front end of the main water spraying mechanism 3, and the auxiliary water spraying mechanism 4 can also spray water to the workpiece. The main water spraying mechanism 3 and the auxiliary water spraying mechanism 4 are respectively responsible for the main cooling and auxiliary cooling functions, and the synergistic effect of the two can flexibly and dynamically adjust the cooling intensity according to the actual needs.

[0050] AsFigure 1 , Figure 2 and Figure 4 As shown, the fixed end of the moving mechanism 5 is connected to the support plate 11, and the telescopic end of the moving mechanism 5 is connected to the auxiliary water spraying mechanism 4, making the distance between the auxiliary water spraying mechanism 4 and the main water spraying mechanism 3 adjustable, thereby adapting to different cooling zones and process requirements. The temperature measuring mechanism is used to measure the temperature of the workpiece, providing a basis for precise control. The control mechanism includes a controller, a first control component 91, and a second control component 92. The first control component 91 controls the water flow rate of the main water spraying mechanism 3, and the second control component 92 controls the water flow rate of the auxiliary water spraying mechanism 4. The temperature measuring mechanism, the first control component 91, the second control component 92, and the water supply mechanism 2 are all electrically connected to the controller. The control mechanism adjusts the water flow rate of the main water spraying mechanism 3 and the auxiliary water spraying mechanism 4, as well as the operating parameters of the water supply mechanism 2, based on the temperature measurement results, improving the automation level and response speed of the cooling process, helping to improve the quality of the cast billet, reduce energy consumption, and enhance the flexibility and applicability of the system.

[0051] In actual operation, the temperature measuring mechanism first detects the surface temperature of the workpiece and transmits it to the controller via an electrical signal. The controller then generates corresponding control commands based on the received signal. For high-temperature areas, the controller increases the water spray volume of the main water spray mechanism 3 through the first control component 91. If the water spray volume of the main water spray mechanism 3 is still insufficient, the second control component 92 activates the auxiliary water spray mechanism 4 to work in coordination. Furthermore, the relative position between the auxiliary water spray mechanism 4 and the main water spray mechanism 3 can be flexibly adjusted using the moving mechanism 5 to further regulate the cooling water flow rate in a specific area, thereby ensuring uniform and efficient cooling of the entire workpiece and ultimately achieving the goal of densifying the internal structure of the casting and ensuring precise and stable external dimensions. The controller can select a suitable existing structure, such as a microcontroller or computer, and can achieve the function of receiving and sending signals through its built-in program without the need for creative program improvements.

[0052] like Figure 1 , Figure 2 and Figure 4 As shown, preferably, the water conveying mechanism 2 includes a water storage component 21 and a water pump 22. The water storage component 21 is located on one side of the support mechanism 1 and on the side facing the workpiece conveying direction to reduce the impact on workpiece conveying. The input end of the water pump 22 is connected to the water storage component 21, the output end of the water pump 22 is connected to the main water spraying mechanism 3, and the water pump 22 is electrically connected to the controller.

[0053] The water pump 22 can control the output water volume according to the temperature measurement result of the temperature measurement mechanism, regulate the flow from the source, realize the accurate control of the secondary cooling water flow, and ensure the stability and reliability of the cooling process. Specifically, through the reasonable layout of the water storage part 21 and the water pump 22 in the water delivery mechanism 2, combined with the control of the working state of the water pump 22 by the controller, not only the utilization rate of water resources is improved, but also the water supply can be flexibly adjusted according to the actual demand, so as to effectively cope with the change of cooling intensity demand under different steel grades and production process conditions, and further improve the quality consistency and production efficiency of the casting blank.

[0054] As shown in Figure 1 , Figure 2 and Figure 4 , optionally, the main water spraying mechanism 3 includes a first water spraying part 31, the auxiliary water spraying mechanism 4 includes a second water spraying part 41, and the first water spraying part 31 and the second water spraying part 41 have the same structure, thereby realizing the unified design of the water spraying part structure in the main water spraying mechanism 3 and the auxiliary water spraying mechanism 4. This design not only simplifies the manufacturing process and reduces the production cost, but also facilitates the maintenance and replacement of parts in the later period. At the same time, since the first water spraying part 31 and the second water spraying part 41 have the same structure, they can be used interchangeably in actual application, improving the flexibility and reliability of the equipment, and further improving the adaptability and operation convenience of the system.

[0055] When it is necessary to adjust the working state of the main water spraying mechanism 3 and the auxiliary water spraying mechanism 4, since the structures of the two are consistent, the maintenance and replacement operations can be unified, thereby reducing the use cost. At the same time, in the production process, this design makes the production and stocking of water spraying parts more convenient, thereby improving the overall efficiency of the system.

[0056] As shown in Figure 1 , Figure 2 and Figure 4 , optionally, the first water spraying part 31 includes a spray head part 311, a flow regulating valve 312, and a screwing part 313, the input end of the flow regulating valve 312 is connected to the water delivery mechanism 2, the output end of the flow regulating valve 312 is connected to the spray head part 311, and the screwing part 313 is connected to the adjusting structure of the flow regulating valve 312. The flow of the flow regulating valve 312 can be adjusted by rotating the screwing part 313 to adjust the flow of the spray head part 311. It can be understood that the device includes necessary water pipes to deliver the cooling water in the water storage part 21 to the main water spraying mechanism 3 and the auxiliary water spraying mechanism 4; the material of the water pipe can be selected as needed, and in this embodiment, most of the water pipes can be made of hard water pipes to play a certain supporting role. The material of the water pipe at different positions can be selected as needed.

[0057] The flow regulating valve 312 can accurately control the water flow from the water supply mechanism 2 to the spray head 311, and the design of the screwing part 313 allows the operator to conveniently adjust the flow of the flow regulating valve 312 through simple rotation, thereby meeting the cooling requirements under different working conditions and achieving fine regulation of the flow of each first water spraying part 31 in the main water spraying mechanism 3. When the water flow of the spray head 311 needs to be changed, the screwing part 313 can be rotated to change the internal structure of the flow regulating valve 312, thereby accurately controlling the water flow through the valve. The flow regulating valve 312 selects a suitable existing structure according to the needs, and the adjustment structure of the flow regulating valve 312 is a structure that can regulate the flow of the flow regulating valve 312 among existing structures, such as the screwing structure of a faucet. This design significantly improves the flexibility and adaptability of the secondary cooling system, while ensuring uniform cooling of the casting blank and optimizing water resource utilization efficiency.

[0058] As shown in Figure 1 , Figure 2 and Figure 4 , optionally, the device further comprises a flow monitoring mechanism, which comprises a main flow meter 61 connected to the water supply mechanism 2 at one end and connected to the main water spraying mechanism 3 at the other end. Specifically, the output end of the water pump 22 is connected to the main flow meter 61. The flow monitoring mechanism can monitor the total water flow of the secondary cooling process in real time, ensuring accurate control of the secondary cooling water flow. Specifically, the main flow meter 61 allows the system to obtain actual total water flow data flowing into the plurality of main water spraying mechanisms 3 from the water supply mechanism 2, thereby providing accurate basis for subsequent flow regulation. This helps to improve the stability and consistency of the casting blank cooling process, reduces quality problems caused by long-term abnormal fluctuations in water flow, and further improves the internal quality of the casting blank and production efficiency.

[0059] Specifically, the flow monitoring mechanism can be electrically connected to the controller, which can include a display screen. During the water supply process from the water supply mechanism 2 to the main water spraying mechanism 3, the main flow meter 61 is installed on the water pipe to accurately measure the water flow and feed the data back to the controller. This process ensures that the actual water flow of the main water spraying mechanism 3 is always within a controllable range, thereby providing stable cooling effect for the casting blank. At the same time, through continuous monitoring of the flow data, possible blockage or leakage problems can be found and solved in time, further improving the reliability and cooling efficiency of the system.

[0060] As shown in Figure 1 , Figure 2 and Figure 4As shown, the main water spraying mechanism 3 and the auxiliary water spraying mechanism 4 are both provided with multiple ones, and the auxiliary water spraying mechanism 4 and the main water spraying mechanism 3 are one-to-one correspondingly arranged. The flow monitoring mechanism includes several sub-flow meters 62, the sub-flow meters 62 correspond to the auxiliary water spraying mechanism 4 one-to-one, one end of the sub-flow meters 62 is connected to the main flow meter 61, and the other end of the sub-flow meters 62 is connected to the main water spraying mechanism 3. The main water spraying mechanism 3 and the auxiliary water spraying mechanism 4 are both provided with multiple ones, and the two are one-to-one corresponding, so that each branch includes one main water spraying mechanism 3 and one auxiliary water spraying mechanism 4, and the flow of the main water spraying mechanism 3 and the auxiliary water spraying mechanism 4 is adjusted respectively, so as to realize the cooling water flow adjustment of each branch, so as to realize the precise water flow adjustment of the corresponding position of the workpiece according to the temperature measurement result of the temperature measuring mechanism. The sub-flow meters 62 in the flow monitoring mechanism can monitor the water flow of the main water spraying mechanism 3 and the auxiliary water spraying mechanism 4 in each branch separately, thereby helping to accurately control the actual cooling effect of each position. In combination with the function of the main flow meter 61, the water distribution of the whole system is more reasonable, and the stability and controllability in the dynamic secondary cooling process are further improved, and the high requirements for the quality of the casting blank under complex production conditions are met. The temperature measuring mechanism can include multiple temperature sensors or temperature measuring probes, which are used to measure the temperature at different positions of the workpiece, and each temperature sensor can cooperate with the first water spraying part 31 and the second water spraying part 41 at the corresponding position, and the local high-temperature position is increased by the controller.

[0061] In the specific implementation process, after the water flow enters the water conveying mechanism 2, it is first uniformly metered by the main flow meter 61, and then distributed to each sub-flow meter 62, and the actual water flow into each main water spraying mechanism 3 and auxiliary water spraying mechanism 4 is accurately metered by the sub-flow meter 62.

[0062] As shown in Figure 1 , Figure 2 and Figure 4 , optionally, the first control assembly 91 includes a first driving part 911 and a first rack 912, the rotating part 313 is a gear, and the rotating parts 313 of the multiple first water spraying parts 31 are all engaged with the first rack 912.

[0063] The first driving member 911 drives the first rack 912 to move, and the engagement relationship between the first rack 912 and the plurality of first water spraying members 31 is used to rotate the flow regulating valve 312 of all the first water spraying members 31 at the same time, so as to uniformly adjust the water flow of each first water spraying member 31. This design not only improves the consistency and efficiency of flow regulation, but also simplifies the operation process, avoids the inconvenience and error caused by adjusting one by one, ensures the uniformity of water flow distribution in the casting blank cooling process, and further improves the quality stability of the casting blank.

[0064] As shown in Figure 1 , Figure 2 and Figure 4 , optionally, the second control assembly 92 is provided with a plurality of second control assemblies 92, and the second control assembly 92 is provided corresponding to the auxiliary water spraying mechanism 4.

It should be noted that the flow regulating valve 312 of the first water spraying member 31 is connected with the support plate 11 through the support structure, and the flow regulating valve 312 of the second water spraying member 41 is connected with the sliding plate 51 through the support structure, so as to improve the limiting effect of the first water spraying member 31 and the second water spraying member 41 in the vertical direction.

The side of the sliding member 72 facing the pushing member 71 is provided with a second inclined surface, which cooperates with the first inclined surface to enable the horizontal movement of the pushing member 71 to drive the vertical movement of the sliding member 72. The lower side of the sliding member 72 is connected to the hooking member 73, which is used to hook the flexible pipe 8, so that when the auxiliary water spraying mechanism 4 approaches the main water spraying mechanism 3, the hooking member 73 lifts the flexible pipe 8. The hooking member 73 can be a structure made of flexible material such as a rope, or it can be made of rigid material such as metal.

[0068] During the approach of the auxiliary water spraying mechanism 4 to the main water spraying mechanism 3, the pushing member 71 horizontally displaces with the movement of the sliding plate 51. Since one end of the pushing member 71 is provided with a first inclined surface, and the sliding member 72 is provided with a second inclined surface that cooperates with it, the two surfaces contact and generate a mutual force. When the pushing member 71 moves horizontally, the horizontal pushing force is converted into a vertical force by the conversion effect between the inclined surfaces, thereby driving the sliding member 72 to slide upward along the support plate 11. Consequently, the hooking member 73 connected to the lower side of the sliding member 72 is lifted synchronously, and then hooks the flexible pipe 8, avoiding interference or wear of the flexible pipe 8 with other components due to the approach of the auxiliary water spraying mechanism 4. This design not only ensures the smooth action of each component during equipment operation, but also effectively improves the stability and reliability of the entire system.

[0069] As shown in Figure 1 , Figure 2 and Figure 4 Figure 1 Figure 2 Figure 4 Figure 1 Figure 2 Figure 4 Figure 1 Figure 2 Figure 4 Figure 1 Figure 2 Figure 4 Figure 1 Figure 2 Figure 4 Figure 1 Figure 2 Figure 4 Figure 1 Figure 2 Figure 4 Figure 1 Figure 2As shown, the lower side of the support plate 11 is provided with a support part 13, and the sliding piece 72 is connected to the support plate 11 through the support part 13, and can vertically slide along the support part 13. The provision of the support part 13 provides accurate guiding for the sliding piece 72, and ensures that it can only move up and down in the predetermined direction, thereby avoiding equipment failure or uneven stress on the flexible pipe 8 due to deviation. This design significantly improves the overall reliability and operation stability of the device, especially during the process of the auxiliary water spraying mechanism 4 approaching the main water spraying mechanism 3, which can effectively ensure the normal working state of the flexible pipe 8, and further optimize the effect of the secondary cooling water flow control.

[0070] It can be understood that the device also includes necessary structures for connection, support, driving, positioning, limiting, sealing, and control, etc., so that the device can normally operate; the shape, size, material, and setting number of each part of the device can be determined according to needs, as long as the corresponding functions can be realized.

[0071] The implementation principle of the secondary cooling water flow control device in the dynamic secondary cooling control system is that the temperature measuring mechanism obtains workpiece temperature data in real time, and the control mechanism adjusts the water flow of the main water spraying mechanism 3 and the auxiliary water spraying mechanism 4 and the working parameters of the water conveying mechanism 2 according to the temperature measurement results, the main water spraying mechanism 3 and the auxiliary water spraying mechanism 4 are respectively responsible for the main cooling and auxiliary cooling functions, and the moving mechanism 5 adjusts the distance between the auxiliary water spraying mechanism 4 and the main water spraying mechanism 3, so that the cooling intensity can be dynamically adjusted according to actual needs, different cooling areas and process requirements are adapted, and the quality of the casting blank is improved.

[0072] The above are preferred embodiments of the present application, and do not limit the protection scope of the present application, therefore: any equivalent changes made according to the structure, shape, principle of the present application should be covered within the protection scope of the present application.
