Description

Technical Field

[0001] The invention relates to the technical field of metallurgical equipment, and in particular to a segmented cooling system and a segmented cooling method. Background Art

[0002] In the production of hot-rolled ultra-thin strips, the cooling process of the hot-rolled ultra-thin strips is one of the key factors affecting the performance of the final product. The cooling process of hot-rolled ultra-thin strips mainly depends on aerosol cooling equipment. However, when the existing aerosol cooling equipment performs aerosol cooling, the gas and droplets generated by the aerosol cooling equipment have problems such as uneven distribution and inaccurate zoning control. In addition, there may be lateral temperature differences on the incoming strip surface, and the lateral cooling intensity of the plate surface is inconsistent, resulting in uneven cooling of the plate surface. When the gas and droplets cannot be distributed in a gradient according to the lateral temperature difference of the incoming strip surface, it is easy to cause inconsistent cooling rates on the surface of the hot-rolled ultra-thin strip, thereby forming areas with large temperature gradients. In addition, it is difficult for existing aerosol cooling equipment to achieve precise zoning control, resulting in large differences in the cooling effects of different areas of the hot-rolled ultra-thin strip, further exacerbating the inconsistency of the microstructure and properties of the hot-rolled ultra-thin strip. Uneven cooling not only affects the physical properties of hot-rolled ultra-thin strips, but may also lead to uneven microstructure, thus affecting key indicators such as shape, strength, and toughness of hot-rolled ultra-thin strips, thereby reducing the quality and production efficiency of hot-rolled ultra-thin strips.

[0038] Implementation Method 1

[0039] Please refer to Figure 1 and Figure 2As shown, in an embodiment of the present invention, a segmented cooling system is provided, which includes a segmented cooling device 100, a regulating valve group 200, a temperature detection module 300, and a segmented cooling control module 400. The segmented cooling device 100 includes a segmented cooling beam 110, and a plurality of nozzles 120 arranged at intervals on the segmented cooling beam 110. The segmented cooling beam 110 is arranged along the width direction of the strip 10 conveying path and is placed on one side of the strip 10 conveying path. The segmented cooling beam 110 is provided with a compressed air inlet 111 and a cooling water inlet 112. The segmented cooling beam 110 is used to distribute water vapor to each nozzle 120; the regulating valve group 200 includes A plurality of nozzle regulating valves 210 connected to each nozzle 120, a compressed air regulating valve 220 connected to the compressed air inlet 111, and a cooling water regulating valve 230 connected to the cooling water inlet 112; a temperature detection module 300 is arranged upstream of the segmented cooling device 100, and the temperature detection module 300 is used to detect the transverse temperature of the surface of the strip 10; a segmented cooling control module 400 is electrically connected to the temperature detection module 300 and the regulating valve group 200, and the segmented cooling control module 400 is used to divide the surface of the strip 10 into multiple cooling zones along the width direction based on the transverse temperature of the surface of the strip 10 and control the water vapor flow in each cooling zone through the regulating valve group 200.

[0040] In general, when the segmented cooling system is used, the segmented cooling device 100 is arranged on the conveying path of the strip 10, and the segmented cooling beam 110 is arranged along the width direction of the strip 10, so that the multiple nozzles 120 are evenly arranged along the width direction of the strip 10. The temperature detection module 300 can scan and record the transverse temperature data of the surface of the strip 10 in real time, and then the segmented cooling control module 400 can divide the surface of the strip 10 into at least one cooling zone along the width direction according to the real-time transverse temperature data, and the segmented cooling control module 400 can also generate corresponding control signals based on the temperature range of the cooling zone, and the control signals can control the working state of the regulating valve group 200, and then automatically adjust the opening and closing state of each nozzle 120 and the water vapor flow rate to ensure the accurate control of the surface temperature of the strip 10.

[0041] The present invention can divide the cooling zones in real time according to the lateral temperature of the surface of the strip 10 by cooperating with the segmented cooling control module 400 and the temperature detection module 300, and control the regulating valve group 200 to adjust the water vapor flow rate of each nozzle 120 in each cooling zone in real time, thereby achieving precise cooling of each cooling zone, avoiding the problem of uneven temperature, having better temperature control accuracy and uniformity of cooling effect, significantly reducing defects such as cracks and warping on the surface of the strip 10, and improving the quality and stability of the product.

[0042] The present invention integrates functions such as temperature scanning, data processing, strategy formulation and execution, and can automatically adjust the opening and closing state of the nozzle 120 and the water vapor flow rate according to the real-time results of the strip surface temperature scanning to form a complete temperature closed-loop control system. This closed-loop control not only ensures the precise control of the strip temperature, but also greatly improves the performance of the strip 10 and the stability of the plate shape.

[0043] In the embodiment of the present invention, the designer can adjust the specific type of the strip 10 according to the use requirements, and no specific limitation is made here. Preferably, the strip 10 is a strip steel. The present invention solves the problems of large lateral temperature difference of the plate surface during the cooling process of the strip steel and uncontrollable steel plate performance, and significantly improves the quality and performance stability of the strip steel product.

[0044] In the embodiment of the present invention, the designer can adjust the specific structure of the segmented cooling control module 400 according to the use requirements, and no specific limitation is made here. For example, the segmented cooling control module 400 includes a data acquisition unit, a control algorithm unit, a signal output unit, a human-computer interaction interface, a power management unit, a communication unit, and a storage unit, so that the control operation can be realized through the segmented cooling control module 400.

[0045] In the embodiment of the present invention, the designer can adjust the number and arrangement of the nozzles 120 according to the use requirements, and no specific restrictions are imposed here. For example, a plurality of nozzles 120 are arranged in one or more rows at intervals to form a nozzle array, and the nozzle array is used to achieve precise spraying on the surface of the strip. These nozzles 120 are precisely arranged and can be flexibly adjusted according to the preset cooling strategy to ensure that the cooling effect is both uniform and efficient.

[0046] Among them, in the height direction, each nozzle 120 covered by each cooling zone is used to realize the cooling of the cooling zone. Through the cooperation of multiple nozzles 120, differentiated control can be achieved in the width direction of the strip 10, with better zone cooling effect.

[0047] In an embodiment of the present invention, the segmented cooling device 100 includes a plurality of segmented cooling beams 110 , and the plurality of segmented cooling beams 110 are arranged at intervals along the conveying path of the strip 10 .

[0048] By arranging a plurality of segmented cooling beams 110 along the conveying path of the strip 10, the plurality of segmented cooling beams 110 can cooperate with each other to achieve a better cooling effect, thereby ensuring a uniform distribution of the surface temperature of the strip 10 and reducing the phenomenon of local overheating or overcooling.

[0049] The designer may adjust the specific number and arrangement of the segmented cooling beams 110 according to the use requirements, and no specific limitation is imposed here. For example, a plurality of segmented cooling beams 110 are arranged so that a plurality of nozzles 120 form a nozzle array of multiple rows and columns.

[0050] In an embodiment of the present invention, the segmented cooling beam 110 is disposed below or above the conveying path of the strip 10 , and the temperature detection module 300 is disposed above the conveying path of the strip 10 .

[0051] The designer can adjust the specific location of the temperature control module according to the use requirements, and no specific limitation is made here. Preferably, the temperature control module is arranged above the strip steel inlet.

[0052] Furthermore, the designer can adjust the location of the segmented cooling beam 110 according to the use requirements, and no specific limitation is made here. In a feasible embodiment, the segmented cooling beam 110 is arranged below the conveying path of the strip 10 and is placed downstream of the temperature control module.

[0053] In another feasible embodiment, the segmented cooling beam 110 is disposed above the conveying path of the strip 10 and is placed downstream of the temperature control module.

[0054] In another feasible embodiment, when a plurality of segmented cooling beams 110 are provided, the plurality of segmented cooling beams 110 can be respectively provided above and below the conveying path of the strip 10, thereby respectively cooling the surfaces on both sides of the strip 10, reducing the temperature gradient, helping to improve the cooling uniformity and improving the cooling efficiency, thereby improving the quality and stability of the product.

[0055] In an embodiment of the present invention, the temperature detection module 300 includes a temperature scanning device, and the temperature scanning device is used to detect the transverse temperature of the surface of the strip 10 .

[0056] The temperature scanning device can detect the transverse temperature distribution of the surface of the strip 10 in real time and accurately, providing accurate temperature data for the segmented cooling control module 400, ensuring accurate control of the cooling process, and significantly improving the uniformity and efficiency of cooling. In addition, the feedback of real-time temperature data enables the system to quickly adjust the cooling amount, shorten the cooling time, and help speed up the production rhythm.

[0057] Of course, in other feasible embodiments, designers can adjust the specific model structure of the temperature detection module 300 according to usage requirements, and no specific limitation is made here.

[0058] In an embodiment of the present invention, the segmented cooling system also includes a cooling water pipeline 500, which is used to connect the cooling water inlet 112 and the cooling water source. The cooling water regulating valve 230 is arranged on the cooling water pipeline 500, and the segmented cooling control module 400 is electrically connected to the cooling water regulating valve 230.

[0059] The cooling water inlet 112 and the cooling water source can be connected through the cooling water pipeline 500, so that the cooling water can enter the segmented cooling beam 110 along the cooling water pipeline 500. In addition, a cooling water control valve is provided on the cooling water pipeline 500, and the delivery amount of the cooling water pipeline 500 can be controlled by the cooling water control valve, thereby playing a role in controlling the cooling amount, which helps to more flexibly control the cooling water flow rate to meet the cooling needs of the strip 10. In addition, by arranging the cooling water regulating valve 230 on the cooling water pipeline 500, the cooling water regulating valve 230 can be kept away from the strip, thereby preventing the high temperature of the strip from affecting the cooling water regulating valve 230.

[0060] Furthermore, the segmented cooling system also includes a compressed air pipeline 600, which is used to connect the compressed air inlet 111 and the compressed air source. The compressed air regulating valve 220 is arranged on the compressed air pipeline 600, and the segmented cooling control module 400 is electrically connected to the compressed air regulating valve 220.

[0061] The compressed air inlet 111 and the compressed air source can be connected through the compressed air pipeline 600, so that the compressed air can enter the segmented cooling beam 110 along the compressed air pipeline 600, and a compressed air regulating valve 220 is arranged on the compressed air pipeline 600, and the delivery amount of the compressed air pipeline 600 can be controlled by the compressed air regulating valve 220. In addition, by arranging the compressed air regulating valve 220 on the compressed air pipeline 600, the compressed air regulating valve 220 can be kept away from the strip, thereby preventing the high temperature of the strip from affecting the compressed air regulating valve 220.

[0062] The cooling water can be pressed into the nozzle 120 by compressed air to generate uniform aerosol, ensuring that the cooling water can be evenly sprayed on the surface of the strip 10, further improving the uniformity of cooling, reducing temperature gradients, and improving the quality and stability of the strip products.

[0063] Furthermore, by electrically connecting the segmented cooling control module 400 to the cooling water regulating valve 230 and the compressed air regulating valve 220, the segmented cooling control module 400 can achieve precise control of the amount of cooling water and compressed air, avoid problems of overcooling or insufficient cooling, ensure the cooling uniformity of the surface temperature of the strip 10, and reduce the waste of cooling water and compressed air.

[0064] Specifically, the segmented cooling control module 400 can control the opening and closing states and opening sizes of the cooling water regulating valve 230 and the compressed air regulating valve 220. Designers can adjust the specific cooling method according to usage requirements, and no specific restrictions are made here.

[0065] When the compressed air regulating valve 220 is closed and the cooling water regulating valve 230 is opened, the cooling water can be delivered to the nozzle 120 by using the cooling water pipeline 500, thereby achieving the effect of single water cooling.

[0066] When the compressed air regulating valve 220 and the cooling water regulating valve 230 are both opened, the dual cooling effect of aerosol and mist can be achieved.

[0067] In an embodiment of the present invention, the segmented cooling beam 110 is provided with a nozzle regulating valve electronic control interface 130 , the nozzle regulating valve electronic control interface 130 is electrically connected to each nozzle regulating valve 210 , and the segmented cooling control module 400 is electrically connected to the nozzle regulating valve electronic control interface 130 .

[0068] Each nozzle regulating valve 210 can be electrically connected to each other through the nozzle regulating valve electronic control interface 130, thereby realizing centralized management of the nozzle regulating valve 210 interface. There is no need for the segmented cooling control module 400 to electrically connect each nozzle regulating valve 210, thereby improving wiring efficiency and system integration.

[0069] Furthermore, each nozzle regulating valve 210 is centrally managed through the nozzle regulating valve electronic control interface 130, which simplifies the maintenance and debugging of the system and reduces the maintenance cost and time.

[0070] In an embodiment of the present invention, the nozzle 120 is an aerosol nozzle, and a plurality of nozzles 120 are arranged at equal intervals on the segmented cooling beam 110 .

[0071] By arranging a plurality of aerosol nozzles at equal intervals on the segmented cooling beam 110, the aerosol nozzles can atomize the cooling water into fine water droplets, increase the contact area between the cooling water and the surface of the strip 10, and improve the cooling efficiency. In addition, the fine water droplets can evaporate quickly, taking away more heat, and further improving the cooling speed.

[0072] Furthermore, the equally spaced aerosol nozzles make the cooling range and effect of each nozzle 120 more consistent. Combined with the independent control of each nozzle regulating valve 210, the surface temperature of the strip 10 can be precisely controlled to avoid local overheating or overcooling.

[0073] At the same time, the atomization effect of the aerosol nozzle makes the utilization rate of cooling water higher, reduces water consumption, reduces production costs, and is also conducive to environmental protection. Designers can adjust the specific model structure of the aerosol nozzle according to the needs of use, and no specific restrictions are made here.

[0074] In the embodiment of the present invention, the designer can adjust the specific model and structure of the nozzle regulating valve 210 according to the use requirements, and no specific limitation is made here. Preferably, the nozzle regulating valve 210 is a pneumatic valve.

[0075] Furthermore, the segmented cooling beam 110 is also provided with an instrument compressed air inlet 113, which is used to provide compressed air to the pneumatic valve. Specifically, the instrument compressed air inlet 113 is used to connect to a compressed air network, thereby providing a power source for the pneumatic valve.

[0076] By setting the nozzle regulating valve 210 as a pneumatic valve, the pneumatic valve has the characteristic of fast response and can act quickly after receiving the instruction of the segmented cooling control module 400 to achieve rapid adjustment of the cooling water flow of the nozzle 120, thereby helping to adjust the cooling effect in time and improving the dynamic response capability of the system.

[0077] In addition, the pneumatic valve has high control accuracy and can realize accurate control of the cooling water flow of the nozzle 120, thereby ensuring that the cooling water can be accurately distributed according to the transverse temperature gradient of the surface of the strip 10, thereby improving the uniformity and efficiency of cooling. The designer can adjust the specific model structure of the pneumatic valve according to the use requirements, and no specific restrictions are made here.

[0078] Implementation Method 2

[0079] Please refer to Figure 1 and Figure 2 As shown, a segmented cooling method is provided in an embodiment of the present invention. The segmented cooling method is implemented by applying the segmented cooling system described in the first embodiment. The segmented cooling method includes the following steps:

[0080] Step 1000: Setting a segmented cooling system on the conveying path of the strip 10.

[0081] Step 2000 : When the strip 10 passes through the temperature detection module 300 , the temperature detection module 300 is used to scan and record the transverse temperature data of the surface of the strip 10 in real time.

[0082] By scanning and recording the transverse temperature data of the surface of the strip 10 in real time through the temperature detection module 300, the temperature change of the surface of the strip 10 can be monitored in real time, ensuring the dynamic adjustment of the cooling process, which helps to improve the accuracy and response speed of cooling.

[0083] Step 3000: Based on the transverse temperature data of the surface of the strip 10, the surface of the strip 10 is divided into at least one cooling zone along the width direction through the segmented cooling control module 400, each cooling zone corresponds to a preset temperature range, and the segmented cooling control module 400 generates a corresponding control signal based on the temperature range of the cooling zone; wherein, at least the opening and closing state of the nozzle 120 and the flow adjustment instruction of the nozzle regulating valve 210 are included.

[0084] By utilizing the segmented cooling control module 400 to realize independent control of the cooling zones, it is ensured that the cooling effect of each cooling zone meets the predetermined standard, thereby improving the uniformity and efficiency of cooling.

[0085] Step 4000: The nozzles 120 and the nozzle regulating valves 210 in each cooling zone perform corresponding actions according to the corresponding control signals, thereby automatically adjusting the water vapor flow of each nozzle 120 to cool the cooling zone.

[0086] The water vapor flow of each nozzle 120 can be automatically controlled by the control signal. This automatic adjustment mechanism can dynamically adjust the cooling parameters according to the actual temperature change, ensure the uniform distribution of the surface temperature of the strip 10, avoid local overheating or overcooling, and improve the quality and stability of the product.

[0087] The specific structure, working principle and beneficial effects of the segmented cooling system are the same as those in the first embodiment, and will not be described in detail here. The present invention can achieve real-time monitoring, precise zoning, automatic adjustment and optimization of the surface temperature of the strip 10, automatic cooling control and management by applying the segmented cooling method, simplify the operation process, and reduce the need for manual intervention, thereby significantly improving the performance and cooling effect of the cooling system, and improving the quality and production efficiency of the product.
