Abstract
Description
[Technical field]
[0001] REFERENCE TO RELATED APPLICATIONS This application claims the benefit of U.S. Provisional Patent Application No. 63 / 267,206, filed January 27, 2022, and entitled "SYSTEMS AND METHODS FOR CONTROLLING THREADING IN A ROLLING MILL," the contents of which are incorporated by reference in their entirety herein.
[0002] This application relates generally to metallurgy, and more specifically to a system and method for controlling threading in a rolling mill for metal substrates. [Background technology]
[0003] During metal processing, rolling may be used to reduce the thickness of a metal substrate (such as a stock sheet or strip of aluminum, aluminum alloys, or various other metals) by passing the metal substrate through a pair of work rolls. Depending on the desired properties of the final metal product, the metal substrate may be hot rolled and / or cold rolled. Hot rolling generally refers to a rolling process in which the temperature of the metal is above the recrystallization temperature of the metal. Cold rolling generally refers to a rolling process in which the temperature of the metal is below the recrystallization temperature of the metal.
[0004] In some cases, one or more operational inputs for controlling the initial flatness of the metal substrate may be erroneous and provided incorrectly, resulting in poor starts that negatively impact both the quality and productivity of the rolled metal substrate. For example, poor starts can cause the metal substrate to be scraped or scraped, resulting in ripples in the center of the metal substrate, and / or ripples on the edges of the metal substrate, which can interrupt production and / or result in material waste as the damaged portions need to be scraped or reworked. Summary of the Invention
[0005] The embodiments of the invention covered by this patent are defined by the claims below, and not by this Summary.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0012] Described herein are systems and methods for controlling a rolling mill at least during the start of rolling. In some embodiments, the systems and methods provided herein may predict one or more start parameters of the rolling mill prior to rolling and, optionally, control at least the start of the rolling operation based on the predicted start parameters. In certain embodiments, the start parameters are based on one or more historical parameters of the rolling mill, including, but not limited to, historical parameters of the rolling mill during a previous rolling operation. In various embodiments, the start parameters are based on the one or more historical parameters and also based on information about the metal substrate being rolled. In some optional embodiments, the historical parameters may be updated after each rolling operation and the start parameters for the subsequent rolling operation may be based on the updated historical parameters. In certain embodiments, the predicted start parameters may be used to predict a probability of start failure and, optionally, the systems and methods described herein may control the rolling mill based on the probability that it is below a predefined threshold. In certain embodiments, the systems and methods provided herein may minimize and / or prevent the occurrence of bad starts during rolling of a metal substrate, which may increase productivity and reduce material waste. Various other benefits and advantages may be realized by the systems and methods provided herein, and the above-mentioned advantages should not be considered limiting.
[0013] Figures 1-3 illustrate an example metal casting system 100, according to various embodiments. Specifically, Figure 1 illustrates the rolling mill 100 prior to rolling a metal substrate 104. Figure 2 illustrates the rolling mill 100 during the start of a rolling operation of the metal substrate 104, and Figure 3 illustrates the rolling mill 100 during rolling of the metal substrate 104.
[0014] In the example of FIGS. 1-3, the rolling mill 100 is a cold rolling mill, but in other examples, the rolling mill 100 can be a hot rolling mill, if desired. The rolling mill 100 includes at least one work table 102 for processing the metal substrate 104. In the embodiment of FIGS. 1-3, the rolling mill 100 includes two work tables 102A-102B. However, in other embodiments, the rolling mill can include any number of work tables 102, if desired, including, but not limited to, a single work table 102, three work tables 102, four work tables 102, or any other desired number of work tables 102, if desired. Each of the work tables 102 includes a pair of work rolls 106A-B and backup rolls 108A-B that support the work rolls 106A-B. In some embodiments, each of the work tables 102 may include one or more intermediate rolls, and the number of intermediate and backup rolls 108A-B should not be considered limiting. A roll gap 110 is defined between the work rolls 106A-B of each of the work tables 102, and during processing of the metal substrate 104, the metal substrate 104 passes through the roll gap 110 between the work rolls 106A-B and advances along a pass line in the processing direction (represented by arrow 113). As the metal substrate 104 passes through the roll gap 110, the thickness of the metal substrate 104 may decrease.
[0015] In various embodiments, the rolling mill 100 includes a controller 114 communicatively coupled to the worktable 102 of the rolling mill 100. The controller 114 may be a variety of computing or processing devices, and may include one or more processors and / or one or more memories, as desired. In certain embodiments, the controller 114 may be programmable using conventional computer components, and in various embodiments, the controller 114 includes a processor that executes code stored in a tangible computer readable medium in a memory (or elsewhere, such as a portable medium, on a server, or in the cloud, among other media) to cause the controller 114 to receive and process data and perform actions and / or control components of the rolling mill 100.
[0016] The controller 114 may be any device capable of executing code, which is a set of instructions to process data and perform actions such as controlling industrial equipment. As non-limiting examples, the controller 114 may take the form of a digitally implemented and / or programmable PID controller, a programmable logic controller, a microprocessor, a server, a desktop or laptop personal computer, a laptop personal computer, a handheld computing device, and a mobile device. Examples of processors include any desired processing circuitry, an application specific integrated circuit (ASIC), programmable logic, a state machine, or other suitable circuitry. The processor may include one processor or any number of processors. The processor may access code stored in a memory. The memory may be any non-transitory computer readable medium configured to tangibly embody code and may include electronic, magnetic, or optical devices. Examples of memory include random access memory (RAM), read only memory (ROM), flash memory, floppy disks, compact disks, digital video devices, magnetic disks, ASICs, configured processors, or other storage devices. The instructions may be stored in the memory or processor as executable code. The instructions may include processor-specific instructions generated by a compiler and / or interpreter from code written in any suitable computer programming language. Optionally, the controller 114 includes a user interface 116 for receiving input from a user. Additionally or alternatively, the controller 114 may include other alternative interfaces that allow the controller 114 to communicate with devices and / or systems external to the controller 114.
[0017] Optionally, the rolling mill 100 may include one or more sensors 118 for detecting one or more parameters of the rolling mill 100 and / or the metal substrate 104 during and / or after the rolling operation of the metal substrate 104. In embodiments in which one or more sensors 118 are included, the one or more sensors 118 may be communicatively coupled to the controller 114. In some embodiments, information detected by the one or more sensors 118 during and / or after the rolling operation may be used as historical parameters of the rolling mill 100, as described in more detail below. The one or more sensors 118 may be of various types of sensors, as desired, including, but not limited to, flatness sensors, roll tilt sensors, roll bending sensors, strip speed sensors, load sensors, gage sensors, mill profile sensors, combinations thereof, and / or various other sensors or combinations of sensors, as desired. The number and locations of the sensors 118 shown in FIGS. 1-3 should not be considered limiting.
[0018] 1-3, a method of rolling a metal substrate 104 using a rolling mill 100 generally includes receiving a supply (e.g., coil) 120 of metal substrate 104, as shown in FIG. 1. With reference to FIG. 2, during start-up of rolling, the metal substrate 104 is first fed to work station 102A. After start-up of rolling, as shown in FIG. 3, the metal substrate 104 is fed to work station 102B and threaded initially through roll gap 110 while being unwound from coil 120. Work stations 102A-B that process the metal substrate 104 may optionally reduce the metal substrate 104 from an initial gauge or thickness to a final gauge or thickness. As described in more detail below, in certain embodiments, to avoid and / or minimize a false start (e.g., during the stage shown in FIG. 2), the rolling mill 100 may predict start-up parameters of the rolling mill 100 based on a prior rolling and control the rolling mill 100 based on the predicted start-up parameters.
[0019] A method 400 of controlling the rolling mill 100 is described in detail below with reference to Figure 4. In some embodiments, one or more of the steps of the method 400 described in detail below may be performed by the controller 114 and / or as otherwise desired.
[0020] At block 402, the method 400 includes receiving and / or accessing historical parameters of the rolling mill 100 from a previous rolling operation. In various embodiments, block 402 is performed prior to rolling the metal substrate 104 (e.g., during the rolling stage shown in FIG. 1). In various embodiments, the historical parameters may be parameters of the rolling mill 100 from a previous rolling operation. In certain embodiments, the historical parameters may be received from one or more sensors 118 during a previous rolling operation, may be accessed from a storage device, system, or memory, may be input by a user, and / or may be received in other manners, as desired. In various embodiments, the historical parameters may be parameters of the rolling mill 100 and / or parameters of a previously rolled metal substrate. As some non-limiting examples, the historical parameters may include, but are not limited to, work roll bending of work tables 102A-B, roll tilt of work rolls 106A-B, rolling load, threading or rolling speed, roll gap size, roll gap shape, flatness of pre-rolled metal substrate, profile of pre-rolled metal substrate, number of backup rolls 108A-B, thickness of pre-rolled metal substrate, combinations thereof, and / or various other parameters from previous rolling operations, as desired. In some embodiments, the historical parameters may optionally be updated after each rolling operation of the rolling mill 100. In such embodiments, the historical parameters may optionally be updated continuously over the operational life of the rolling mill 100.
[0021] At block 404, the method 400 includes receiving and / or accessing information regarding the metal substrate 104 to be rolled prior to rolling the metal substrate 104 at the rolling mill 100. In various embodiments, block 404 includes receiving a coil 120 of metal substrate 104 at the rolling mill 100, and optionally, block 404 includes receiving a coil 120 of metal substrate 104, where the metal substrate 104 is aluminum or an aluminum alloy, such as a 1xxx series aluminum alloy, a 2xxx series aluminum alloy, a 3xxx series aluminum alloy, a 4xxx series aluminum alloy, a 5xxx series aluminum alloy, a 6xxx series aluminum alloy, a 7xxx series aluminum alloy, or an 8xxx series aluminum alloy, etc. In other embodiments, the coil 120 may be received at any time prior to the start of rolling at block 408, as described below. In some embodiments, the substrate information regarding the metal substrate 104 may be detected (e.g., using sensors and / or other devices as desired), provided by a user (e.g., using the user interface 116 on the controller 114), and / or received in other manners as desired. In various embodiments, the substrate information regarding the metal substrate 104 may include, without limitation, an initial gauge of the metal substrate 104 before rolling, a target end gauge of the metal substrate 104, a composition of the metal substrate 104, a width of the metal substrate 104, a temperature of the metal substrate 104 before rolling, combinations thereof, and / or various other information regarding the metal substrate 104 before rolling, as desired.
[0022] At block 406, the method 400 includes predicting one or more start parameters of the rolling mill 100 prior to rolling the metal substrate 104. In certain embodiments, block 406 includes predicting one or more start parameters of the rolling mill based on the historical parameter(s) from block 402 and the substrate information from block 404. The one or more start parameters can be various start parameters of the rolling mill 100, as desired. The start parameters include, but are not limited to, work roll tilt, work roll bending, strip threading speed, roll gap size and / or shape, rolling load distribution, combinations thereof, and / or various other start parameters, as desired. As two non-limiting examples, the start parameters can be work roll tilt and / or work roll bending.
[0023] In embodiments where the rolling mill 100 includes multiple work tables, the start parameters may be predicted for each of the work tables. In embodiments with multiple work tables, the predicted start parameters for one work table need not be the same as the predicted start parameters for another work table. As a non-limiting example, as shown in FIGS. 1-3, the controller 114 may predict a tilt set point for the work roll 108A of the work table 102A (18.4 μm) and a tilt set point for the work roll 108A of the work table 102B (−112.6 μm). As a further non-limiting example, the controller 114 may predict a bend set point for the work roll 108A of the work table 102A (−41%) and a bend set point for the work roll 108A of the work table 102A (−25%). In some non-limiting examples, the block 406 optionally includes predicting at least two start parameters for each of the work tables 102 of the rolling mill. If desired, various other starting parameters and / or combinations of starting parameters may be predicted based on historical parameters and substrate information.
[0024] Optionally, block 406 may include determining a probability of a poor start based on the predicted start parameters. In such embodiments, block 406 may optionally include comparing the predicted start parameters to historical data from good starts and poor starts (as determined by controller 114 and / or a user). In other embodiments, various other techniques may be used to determine the probability of a poor start using the predicted start parameters. In some embodiments, when block 406 includes determining a probability of a poor start, block 406 may further include comparing the probability to a predefined threshold. The predefined threshold may be a variety of thresholds, as desired. As some non-limiting examples, the predefined threshold may be 5%, 10%, 15%, 20%, 25%, 30%, and / or any other threshold, as desired. In other embodiments, the threshold may be less than 5% and / or greater than 30%. As described in more detail below, controller 114 may control mill 100 according to the predicted start parameters based on the probability being equal to or less than the predefined threshold.
[0025] At block 408, the method 400 includes controlling the start of rolling the metal substrate 104 based on the predicted start parameters (e.g., the stage of rolling shown in FIG. 2). In some embodiments, block 408 may include controlling the rolling mill 100 such that the rolling mill 100 operates with the predicted start parameters. As a non-limiting example, block 408 may include controlling the work tables 102A-B such that the work rolls 106A-B have work roll bends and work roll tilts that match the predicted work roll bends and work roll tilts from block 406. In embodiments where the method 400 includes determining a probability of a bad start at block 406, the method may optionally not proceed to block 408 unless the determined probability is equal to or less than a predefined threshold.
[0026] In certain embodiments, controlling the start of rolling in block 408 optionally includes presenting the predicted start parameters to a user, as desired, using the user interface 116 and / or other mechanisms. In such embodiments, block 408 may optionally allow a user to override the predicted start parameters and instead control the rolling mill 100 using start parameters entered by the user.
[0027] After rolling begins, the controller 114 may continue to control the mill 100 according to predicted start parameters and / or as otherwise desired as the metal substrate 104 is rolled during steady state rolling. Optionally, one or more sensors 118 may monitor or detect the mill and / or the metal substrate 104 being rolled, and such data may be stored as new historical data for a subsequent rolling operation and / or may be used to update previous historical data as new historical data for a subsequent rolling operation. In some embodiments, updating previous historical data may enable tracking of the performance of the mill 100, and such performance history may optionally be used as historical parameters in addition to or in combination with historical parameters from previous rolling operations.
