Description

Technical Field

[0001] This application relates to the field of intelligent control technology, and in particular to a control method, device, electronic equipment and storage medium for a metal foil rolling mill. Background Technology

[0002] A metal foil rolling mill can roll a ductile metal sheet into a metal foil. Taking an aluminum foil rolling mill as an example, it can roll hot-rolled aluminum strip through the main rolls of the aluminum foil rolling mill in several passes to obtain aluminum foil of a set thickness.

[0003] When producing metal foil rolls using a metal foil rolling mill, each roll typically needs to be produced to a set length. To address this, the control scheme for metal foil rolling mills in related technologies generally calculates the real-time length of the produced metal foil rolls by multiplying the winding linear speed (the winding linear speed is the linear speed of the winding shaft of the metal foil rolling mill, used to wind up the metal foil) by time, and stops the metal foil rolling mill when the real-time length equals the required set length.

[0004] However, since the foil rolling mill cannot stop instantly after a stop command is issued, but rather gradually decelerates to a stop, and given the slippage rate of the foil rolling mill, the winding speed and the main axis speed are not the same. This results in a significant error between the calculated real-time length of the foil roll obtained by multiplying the winding speed by time and the actual length of the foil roll. Consequently, existing foil rolling mill control schemes often produce foil rolls with a large deviation from the required set length, making it difficult to meet production demands. Therefore, a new technical solution is needed to at least partially improve this technical problem. Summary of the Invention

[0005] To at least partially solve the above-mentioned technical problems, embodiments of this application provide a control method, apparatus, electronic device, and storage medium for a metal foil rolling mill.

[0006] According to one aspect of the embodiments of this application, an embodiment of this application provides a control method for a metal foil rolling mill, wherein the metal foil rolling mill includes a winding shaft, the winding shaft being used to wind up a metal foil rolled to a predetermined thickness range by the metal foil rolling mill onto the winding shaft during rotation, the method comprising:

[0007] Determine the first speed at which the winding shaft winds up the metal foil at the current moment;

[0008] Based on the first speed and the preset stopping time, determine the remaining length of metal foil that the winding shaft can wind up within the preset stopping time after the current moment if the metal foil rolling mill is stopped at the current moment.

[0009] Determine the real-time length of the metal foil that has been wound up by the take-up shaft at the current moment;

[0010] If the sum of the real-time length and the remaining length is greater than or equal to the set length, then the metal foil rolling mill is stopped.

[0011] In some optional embodiments, determining the first speed at which the take-up shaft winds up the metal foil at the current moment includes: obtaining the first rotational speed of the take-up shaft at the current moment; obtaining the first diameter of the metal foil roll formed by the metal foil wound on the take-up shaft at the current moment; and determining the first speed based on the first rotational speed and the first diameter.

[0012] In some optional embodiments, determining the first speed based on the first rotational speed and the first diameter includes: determining the first speed using the following formula:

[0013] v1=πD1n1

[0014] Where v1 represents the first speed, D1 represents the first diameter, and n1 represents the first rotational speed.

[0015] In some optional embodiments, determining the real-time length of the metal foil wound on the take-up reel at the current moment includes: obtaining the radius of the take-up reel as an initial radius; obtaining the first radius of the metal foil roll formed by the metal foil wound on the take-up reel at the current moment; and determining the real-time length of the metal foil wound on the take-up reel at the current moment based on the initial radius, the first radius, and the predetermined thickness range.

[0016] In some optional embodiments, determining the real-time length of the metal foil wound by the take-up reel at the current moment, based on the initial radius, the first radius, and the predetermined thickness range, includes:

[0017] The real-time length is determined by the following formula:

[0018]

[0019] Among them, L ss R1 is used to characterize the real-time length, R0 is used to characterize the first radius, σ is used to characterize the initial radius, W0 is used to characterize the preset offset, and the preset thickness W0 is located within the predetermined thickness range.

[0020] In some optional embodiments, determining the remaining length of metal foil that the winding shaft could wind within a preset stopping time after the current moment if the metal foil mill is stopped at the current moment, based on the first speed and a preset stopping time, includes: determining the remaining length using the following formula:

[0021] L sy =v1t / 2

[0022] Among them, L sy v1 is used to represent the remaining length, v1 is used to represent the first speed, and t is used to represent the preset parking time.

[0023] According to another two aspects of the embodiments of this application, the embodiments of this application provide a control device for a metal foil rolling mill, wherein the metal foil rolling mill includes a winding shaft, the winding shaft being used to wind up a metal foil rolled to a predetermined thickness range by the metal foil rolling mill onto the winding shaft during rotation, the device comprising:

[0024] The first determining module is used to determine the first speed at which the winding shaft winds up the metal foil at the current moment;

[0025] The second determining module is used to determine, based on the first speed and the preset stopping time, the remaining length of the metal foil that the winding shaft can wind up within the preset stopping time after the current moment if the metal foil rolling mill is stopped at the current moment.

[0026] The third determining module is used to determine the real-time length of the metal foil that has been wound up by the take-up shaft at the current moment;

[0027] The parking control module is used to control the metal foil rolling mill to stop if the sum of the real-time length and the remaining length is greater than or equal to a set length.

[0028] According to another aspect of the embodiments of this application, an electronic device is provided, including: a processor, a communication interface, a memory, and a communication bus. The processor, the communication interface, and the memory communicate with each other through the communication bus. The memory is used to store at least one executable instruction, which causes the processor to perform the operation corresponding to the control method of the metal foil rolling mill provided in any of the first aspects above.

[0029] According to another aspect of the embodiments of this application, the embodiments of this application provide a computer-readable storage medium storing computer instructions, which, when executed by a processor, cause the processor to perform the control method for a metal foil rolling mill provided in any of the first aspects above.

[0030] According to another aspect of the embodiments of this application, the embodiments of this application provide a computer program product that is tangibly stored on a computer-readable medium and includes computer-executable instructions that, when executed, cause at least one processor to perform the control method for a metal foil rolling mill provided in any of the first aspects above.

[0031] The control method for the metal foil rolling mill of this application can determine the first speed at which the winding shaft of the metal foil rolling mill winds up the metal foil at the current moment. Based on the first speed and a preset stopping time, it can determine the remaining length of the metal foil that the winding shaft can wind up within a preset stopping time after the current moment if the metal foil rolling mill is stopped at the current moment. It can also determine the real-time length of the metal foil already wound up by the winding shaft at the current moment. If the sum of the real-time length and the remaining length is greater than or equal to a set length, the metal foil rolling mill is stopped. Therefore, the technical solution of this application considers and calculates the remaining length of the metal foil that the winding shaft can wind up during the metal foil rolling mill's stopping process, and controls the metal foil rolling mill to stop in advance when the remaining length and the real-time length of the wound metal foil are greater than or equal to a set length. Compared with the control methods in the prior art, this can effectively reduce the deviation between the length of the final metal foil roll produced by the metal foil rolling mill (i.e., the metal foil roll formed by the metal foil wound on the winding shaft when the final stopping is completed) and the required set length, thereby effectively meeting production needs.

[0042] To enable those skilled in the art to better understand the technical solutions in the embodiments of this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art should fall within the protection scope of the embodiments of this application.

[0043] To at least partially address the problems existing in the prior art, this application provides a control method for a metal foil rolling mill. This control method can be executed by a computer device capable of data processing. The computer device may include one or more processing units, such as a CPU, MCU, PLC, etc. Alternatively, the control method for the metal foil rolling mill may also be executed and data processed based on a cloud system, edge computing system, etc. It should be understood that no limitation is made in this regard in the embodiments of this application.

[0044] This application does not limit the type of metal foil rolling mill. For example, in some embodiments, it may be an aluminum foil rolling mill, and the metal foil is aluminum foil. For ease of explanation, the following description uses an aluminum foil rolling mill as an example.

[0045] Before providing a detailed description of the control method for the metal foil rolling mill, a brief description of the composition structure of an optional metal foil rolling mill of this application will be given first. Figure 1 An optional schematic diagram of a metal foil rolling mill according to an embodiment of this application is shown. (Refer to...) Figure 1As shown, the metal foil rolling mill 100 includes a take-up shaft 101, which is used to wind up the metal foil 200 rolled to a predetermined thickness range by the metal foil rolling mill 100 during rotation. Optionally, the take-up shaft 101 can be a drum that can be driven to rotate by a drive mechanism in the metal foil rolling mill 100 (for example, the drive mechanism may include a drive motor, and the drum (i.e., the take-up shaft 101) is driven to rotate by the drive motor; specifically, the drum (i.e., the take-up shaft 101) can be held by a clamp, and the drive motor drives the clamp to rotate, thereby driving the drum (i.e., the take-up shaft 101) to rotate), thereby serving the function of winding up the metal foil 200.

[0046] The thickness of the metal foil 200 is within a predetermined thickness range because the metal foil rolling mill 100 inevitably has errors in practice. The metal foil 200 obtained when rolling the metal sheet cannot be exactly the same set thickness. Therefore, while meeting accuracy requirements, it may fluctuate within a predetermined thickness range, and the upper and lower limits of this predetermined thickness range can differ only slightly. For example, when producing metal foil, a set thickness of 0.02 mm can be used, and the predetermined thickness range can be 0.02 mm ± 0.0005 mm, that is, 0.0205 mm to 0.0195 mm. Of course, this is only an example and does not constitute any limitation on this application.

[0047] Optionally, refer to Figure 1The following example briefly illustrates an optional configuration and operating process of the metal foil rolling mill 100. In terms of configuration, the metal foil rolling mill 100 includes: an unwinding shaft 102, an unwinding shaft drive mechanism 1021, a take-up shaft 101, a take-up shaft drive mechanism 1011, a flattening roll 1012, an inlet-side corner roll assembly, an outlet-side corner roll assembly, a first traction roll 1041, a second traction roll 1042, a first mill roll 1051, and a second mill roll 1052; wherein, the unwinding shaft 102 has a wound metal sheet (i.e., the raw material for rolling the metal foil 200 by the metal foil rolling mill 100), which can be a roll; the unwinding shaft drive mechanism 1021 may include a drive motor and a clamp. The clamp holds the unwinding shaft 102, and the drive motor drives the clamp to rotate, thereby causing the clamp to rotate the unwinding shaft 102. The take-up shaft 101 can be a drum, which is used to wind the metal foil 200 rolled to a predetermined thickness range by the metal foil mill 100 onto the take-up shaft 101 during rotation. The take-up shaft drive mechanism 1011 may include another drive motor and another clamp, which holds the take-up shaft 101, and the drive motor drives the clamp to rotate, thereby causing the clamp to rotate the take-up shaft 101. The flattening roller 1012 is used to press the metal foil 200 to be wound onto the take-up shaft 101. On the reel 101, the take-up reel 101 is better able to perform take-up; the inlet-side corner roll assembly includes a first inlet-side corner roll 1031 and a second inlet-side corner roll 1032, and the outlet-side corner roll assembly includes a first outlet-side corner roll 1033 and a second outlet-side corner roll 1034. The inlet-side corner roll assembly and the outlet-side corner roll assembly are used to establish tension and tighten the metal sheet or metal foil to facilitate rolling and take-up; the first traction roll 1041, the second traction roll 1042, the first mill roll 1051 and the second mill roll 1052 can all be driven by other drive structures of the metal foil mill 100, the first traction roll 1041... The first and second traction rollers 1041 and 1042 are used to traction the metal foil 200. Optionally, the first and second mill rollers 1051 and 1052 can be driven by a hydraulic drive structure. The first and second mill rollers 1051 and 1052 squeeze the first and second traction rollers 1041 and 1042 in the vertical direction to provide rolling force to roll the metal sheet. The rolling force is larger when the metal sheet is thicker and smaller when the metal sheet is thinner, thereby controlling the thickness accuracy of the rolled metal foil 200. Based on this rolling, metal foil 200 within a predetermined thickness range is obtained. It should be understood that the composition of this metal foil rolling mill 100 is not intended to limit any aspect of the embodiments of this application.

[0048] In the working process: Before the metal foil rolling mill 100 officially starts operation, the operator can first pull out the metal sheet wound on the unwinding shaft 102, and let it pass through the first inlet corner roll 1031, the second inlet corner roll 1032, the first traction roller 1041 and the second traction roller 1042, the first outlet corner roll 1033, the second outlet corner roll 1034 and the flattening roller 1012 in sequence, so that the metal sheet establishes a stable tension and tightens, and then is fixedly connected to the take-up shaft 101; then the metal foil rolling mill 100 is run. 0. The first rolling mill roll 1051 and the second rolling mill roll 1052 press the first traction roll 1041 and the second traction roll 1042 in the vertical direction to provide rolling force to roll the metal sheet. The rolling force is larger when the metal sheet is thicker and smaller when the metal sheet is thinner, thereby controlling the thickness accuracy of the rolled metal foil 200. Based on this, metal foil 200 within a predetermined thickness range is rolled, and the metal foil 200 is drawn along the first traction roll 1041 and the second traction roll 1042. Figure 1 As shown by the arrow in the example, after the take-up shaft 101 takes up the initial portion of the metal plate (i.e., the metal plate between the second traction roller 1042 and the take-up shaft 101 before the metal foil mill 100 officially starts working), it can take up the metal foil 200 rolled to a predetermined thickness range. When the length of the metal foil 200 wound on the take-up shaft 101 is sufficient, the take-up shaft 101 can be removed and replaced with another take-up shaft. When the metal foil mill 100 stops, all its structures start to stop simultaneously, and the deceleration is gradual until it stops. The metal foil mill 100 has a slip rate, and the take-up linear speed of the metal foil mill 100 (i.e., the linear speed of the take-up shaft 101) is not the same as the main axis speed of the metal foil mill 100 (the main axis speed is equal to the speed at which the first traction roller 1041 and the second traction roller 1042 traction the metal foil 200). It should be understood that this working process is not intended to limit any aspect of the embodiments of this application.

[0049] The following section will provide a detailed explanation of each step in the control method for the metal foil rolling mill of this application.

[0050] Figure 2 An optional flowchart of a control method for a metal foil rolling mill according to an embodiment of this application is shown. According to one aspect of an embodiment of this application, referring to... Figure 2 The flowchart in this application illustrates a control method for a metal foil rolling mill, which includes the following steps S201, S202, S203, and S204:

[0051] Step S201: Determine the first speed at which the winding shaft 101 winds up the metal foil 200 at the current moment.

[0052] Specifically, the first speed can be the linear speed at which the winding shaft 101 winds up the metal foil 200 at the current moment. The first speed can be determined in any suitable manner in this application, and no limitation is imposed. For example, it can be measured using a preset speed sensor.

[0053] In some alternative embodiments, refer to Figure 3 The flowchart in the diagram shows that step S201 may include sub-steps S2011, S2012 and S2013.

[0054] Sub-step S2011: Obtain the first rotational speed of the take-up shaft 101 at the current moment.

[0055] Optionally, the first rotational speed can be directly measured by a preset rotational speed sensor, or it can be directly monitored by a motor driver electrically connected to the drive motor that drives the take-up shaft 101 to rotate, or it can be obtained by other means. This application does not impose any restrictions on this.

[0056] Sub-step S2012: Obtain the first diameter of the metal foil roll formed by the metal foil 200 wound on the take-up shaft 101 at the current moment.

[0057] Optionally, the first diameter can be directly measured by a preset thickness sensor, or it can be obtained by other means, which is not limited in this application.

[0058] Specifically, if the metal foil roll formed by the metal foil 200 wound on the winding shaft 101 is considered to be cylindrical, then the first diameter is the outer diameter of the metal foil roll. (Refer to...) Figure 4 As shown, an example of the first diameter D1 of the metal foil roll 201 is illustrated, which should be understood as, and not as, any limitation thereof, in this application.

[0059] Sub-step S2013: Determine the first speed based on the first rotational speed and the first diameter.

[0060] In this application, through the optional embodiments of steps S2011 to S2013 described above, the first speed at which the winding shaft 101 winds up the metal foil 200 at the current moment can be accurately determined, so that subsequent steps can perform data processing based on the first speed.

[0061] In some optional embodiments, sub-step S2013 specifically includes: determining the first velocity using the following formula:

[0062] v1=πD1n1

[0063] Where v1 represents the first velocity, D1 represents the first diameter, and n1 represents the first rotational speed.

[0064] Based on this, this application can accurately calculate the first speed v1 of the winding shaft 101 winding the metal foil 200 at the current moment, so that subsequent steps can perform data processing based on the first speed v1.

[0065] Step S202: Based on the first speed and the preset stopping time, determine the remaining length of the metal foil 200 that the winding shaft 101 can wind up within the preset stopping time after the current moment if the metal foil mill 100 is stopped at the current moment.

[0066] Specifically, the preset stopping time is a fixed parameter of the foil rolling mill 100, which can be preset. It indicates the total time from when the foil rolling mill 100 starts stopping after receiving the stopping command to when the stopping is completed. For example, if the preset stopping time is 10 seconds, then it will take 10 seconds for the foil rolling mill 100 to stop after receiving the stopping command. Therefore, the remaining length is the length of the foil 200 that the winding shaft 101 of the foil rolling mill 100 would wind up during the time from the current moment until the stopping is completed, if the stopping is controlled at the current moment.

[0067] In some optional embodiments, step S202 specifically includes: determining the remaining length using the following formula:

[0068] L sy =v1t / 2

[0069] Among them, L sy v1 is used to represent the remaining length, v1 is used to represent the first speed, and t is used to represent the preset stopping time.

[0070] Based on this, this application can accurately calculate the remaining length L of the metal foil 200 that can be wound up by the winding shaft 101 within a preset stopping time after the current moment if the metal foil mill 100 is stopped at the current moment. sy This is so that subsequent steps can be based on the remaining length L. sy Perform data processing.

[0071] Step S203: Determine the real-time length of the metal foil 200 that has been wound up by the winding shaft 101 at the current moment.

[0072] In some alternative embodiments, refer to Figure 5 In the flowchart, step S203 may include sub-steps S2031, S2032 and S2033.

[0073] Sub-step S2031: Obtain the radius of the take-up spool 101 as the initial radius.

[0074] Specifically, the radius of the take-up spool 101 is a fixed value, so it can be obtained directly and used as the initial radius R0.

[0075] Sub-step S2032: Obtain the first radius of the metal foil roll 201 formed by the metal foil 200 wound on the take-up reel 101 at the current moment.

[0076] Specifically, if the metal foil roll 201 formed by the metal foil 200 wound on the take-up shaft 101 is considered to be cylindrical, then the first radius is half the outer diameter of the metal foil roll 201, and the first radius is equal to half the aforementioned first diameter. (Refer to...) Figure 4 As shown, an example of the first radius R1 of the metal foil roll 201 is illustrated, which should be understood as, and not as, any limitation thereof in this application.

[0077] Sub-step S2033: Determine the real-time length of the metal foil 200 that has been wound up by the winding shaft 101 at the current moment, based on the initial radius, the first radius, and the predetermined thickness range.

[0078] In this application, through the optional embodiments of steps S2031 to S2033 described above, the real-time length of the metal foil 200 that has been wound up by the winding shaft 101 at the current moment can be accurately determined, so that subsequent steps can perform data processing based on the real-time length.

[0079] In some optional embodiments, step S2033 specifically includes: determining the real-time length using the following formula:

[0080]

[0081] Among them, L ss R1 is used to represent the real-time length, R0 is used to represent the first radius, σ is used to represent the initial radius, W0 is used to represent the preset offset, and the preset thickness W0 is within the predetermined thickness range.

[0082] Optionally, the preset thickness W0 can be set to the middle value of a predetermined thickness range, or it can be the maximum or minimum value, depending on the needs. This application does not impose any restrictions on this.

[0083] The formula incorporates a preset offset σ into the calculation, which reduces the calculation error caused by the thickness of the metal plate wound by the take-up shaft 101 before the take-up foil 200. A suitable preset offset σ is beneficial for improving the real-time calculation length L. ss The accuracy. The preset offset σ can be set as needed. For example, the preset offset σ can be based on the metal sheet wound by the take-up shaft 101 before the take-up foil 200 (for this part, please refer to the previous working process for understanding). Figure 4The thickness of the metal sheet (not shown in the diagram) can be adaptively set. For example, if the wound metal sheet forms one turn on the winding shaft 101, it can be set to 1 times the metal sheet thickness; if the wound metal sheet forms multiple turns on the winding shaft, it can be set to multiple times the metal sheet thickness. This application does not impose any limitations on this. Alternatively, the preset offset σ can also be set directly to a fixed value as needed, regardless of the metal sheet thickness, when the accuracy requirements are met. This application does not impose any limitations on this.

[0084] Based on this, this application can accurately calculate the real-time length L of the metal foil 200 that has been wound up by the take-up reel 101 at the current moment through this method. ss This is to facilitate subsequent calculations based on the real-time length L. ss Perform data processing.

[0085] Step S204: If the sum of the real-time length and the remaining length is greater than or equal to the set length, then control the metal foil rolling mill 100 to stop.

[0086] The set length in this application can be the length of the metal foil roll to be produced by the metal foil rolling mill 100. The length of the metal foil roll is also the length of the metal foil that forms the metal foil roll. The set length can be set as needed. For example, if it is necessary to produce a metal foil roll with a length of 10 meters by the metal foil rolling mill 100, the set length can be set to 10 meters; if it is necessary to produce a metal foil roll with a length of 20 meters by the metal foil rolling mill 100, the set length can be set to 20 meters.

[0087] Specifically, in this application, real-time monitoring and calculation are used to determine when the real-time length L... ss Remaining length L sy and set length L ys The following conditions must be met between L: ss +L sy ≥L ys If the above conditions are met, a stop command is sent to the foil rolling mill 100 to control the foil rolling mill 100 to stop. Pre-stopping the foil rolling mill 100 when the above conditions are met can effectively reduce the length of the foil roll formed by the foil 200 wound on the winding shaft 101 at the time of final stopping of the foil rolling mill 100 from the required set length L. ys The deviation between them.

[0088] Based on this, the control method for the metal foil rolling mill of this application can determine the first speed at which the winding shaft of the metal foil rolling mill winds up the metal foil at the current moment, and can determine the remaining length of the metal foil that the winding shaft can wind up within the preset stopping time after the current moment if the metal foil rolling mill is stopped at the current moment, based on the first speed and the preset stopping time, and can determine the real-time length of the metal foil already wound up by the winding shaft at the current moment. If the sum of the real-time length and the remaining length is greater than or equal to the set length, the metal foil rolling mill is stopped. Therefore, the technical solution of this application considers and calculates the remaining length of the metal foil that the winding shaft can wind up during the stopping process of the metal foil rolling mill, and controls the metal foil rolling mill to stop in advance when the remaining length and the real-time length of the wound metal foil are greater than or equal to the set length. Compared with the control method in the prior art, it can effectively reduce the deviation between the length of the final metal foil roll produced by the metal foil rolling mill (i.e., the metal foil roll formed by the metal foil wound on the winding shaft when the final stopping is completed) and the required set length, thereby effectively meeting the production requirements.

[0089] It is understood that the above content is only an exemplary explanation of the control method of the metal foil rolling mill in the embodiments of this application, and is not intended to limit the embodiments of this application.
