Description

Technical Field

[0001] The present application belongs to the technical field of annealing and drawing wire, and in particular relates to a continuous operation control method of an annealing and drawing wire machine and an annealing and drawing wire machine. Background Art The continuous operation control method for annealing and drawing machines uses integrated technical means to ensure stable annealing and drawing operations over extended periods, while also guaranteeing product quality, production efficiency, and equipment reliability. Its core goal is to achieve automated control of the entire process, from wire annealing to drawing, through multi-dimensional parameter coordination, real-time monitoring, and dynamic adjustment.

[0002] In the related art, in the metal wire annealing process, residual stresses accumulated during the rolling or drawing process exist inside the raw materials that have not been pre-treated. These stresses may be released unevenly during the heating stage at the beginning of annealing, and the dynamic changes in stress will cause the metal wire to produce axial micro-vibration or radial displacement, causing random fluctuations in the effective contact area between the wire and the conductive brush. When the contact area decreases, the contact resistance in the circuit formed by the wire and the conductive brush increases. In the constant power heating mode, the change in contact resistance will directly cause abnormal voltage distribution on the metal wire, and then cause the heating power to deviate from the set value when the contact area fluctuates. The non-steady-state distribution of the temperature field will destroy the uniform austenitization process required for the annealing process, resulting in inconsistent grain growth inside the metal wire, resulting in different degrees of grain growth at different positions of the wire, and then resulting in different strengths of the wire at different positions after wire annealing. Using the originally set wire drawing force for wire drawing will lead to a mismatch between the wire strength and the wire drawing force, resulting in reduced uniformity of wire arrangement, and in severe cases, it may also cause wire breakage.

[0028] In the related art, in the metal wire annealing process, residual stresses accumulated during the rolling or drawing process exist inside the raw materials that have not been pretreated. These stresses may be released unevenly during the heating stage at the beginning of annealing, and the dynamic changes in stress will cause the metal wire to produce axial micro-vibration or radial displacement, causing random fluctuations in the effective contact area between the wire and the conductive brush. When the contact area decreases, the contact resistance in the circuit formed by the wire and the conductive brush increases. In the constant power heating mode, the change in contact resistance will directly cause abnormal voltage distribution on the metal wire, and then cause the heating power to deviate from the set value when the contact area fluctuates. The non-steady-state distribution of the temperature field will destroy the uniform austenitization process required for the annealing process, resulting in inconsistent grain growth inside the metal wire, resulting in different degrees of grain growth at different positions of the wire, and then resulting in different strengths of the wire at different positions after wire annealing. Using the originally set wire drawing force for wire drawing will lead to a mismatch between the wire strength and the wire drawing force, resulting in reduced uniformity of wire arrangement, and in severe cases, it may also cause wire breakage.

[0029] To address the above-mentioned issues, embodiments of the present application provide a continuous operation control system for an annealing and drawing machine. The method first obtains an annealing parameter reflecting set parameters for annealing a wire rod and a drawing length reflecting the length of the wire rod between the completion of the annealing stage and the entry into the drawing stage in the annealing and drawing machine. The annealing and drawing machine is then annealed based on the annealing parameter. First temperature information is monitored in real time at a first position reflecting a non-endpoint position of the heating stage during annealing of the wire rod, and second temperature information is monitored in real time at a second position reflecting an end position of the heating stage during annealing of the wire rod. The first and second temperature information are analyzed to obtain an annealing condition chain representing a timing chain of different annealing conditions corresponding to different wire rod lengths. Finally, the annealing condition chain and the drawing length are processed to obtain a drawing adjustment strategy reflecting a tension change strategy of the drawing device of the annealing and drawing machine for the wire rod after annealing.

[0030] The continuous operation control method of the annealing and drawing machine provided in the embodiment of the present application can be applied to the annealing and drawing machine. In this case, the annealing and drawing machine is the executor of the continuous operation control method of the annealing and drawing machine provided in the embodiment of the present application. The embodiment of the present application does not impose any restrictions on the specific type of the annealing and drawing machine.

[0031] For example, an annealing and drawing machine includes an annealing device, a drawing device, and a control device. The annealing device and the drawing device are both electrically connected to the control device. The annealing device includes an annealing mechanism, a first detection device, and a second detection device. The annealing mechanism is used to anneal the wire. For example, the annealing mechanism can be a contact brush annealing system. The first and second detection devices are both used to detect the wire temperature. For example, the first and second detection devices can be temperature sensors or infrared sensors. The first detection device is located between the first and second conductive brushes. The second detection device is located at the second conductive brush. The direction from the first conductive brush to the second conductive brush is the annealing direction. The drawing device is a subsequent process step of the annealing device. The drawing device includes a guide wire mechanism and a drawing mechanism. The drawing mechanism is used to combine multiple annealed wire segments into a single drawn wire. For example, the drawing mechanism can be a traditional mechanical drawing machine or an automated drawing machine. The guide wire mechanism is used to guide the annealed wire into the drawing mechanism. For example, the guide wire mechanism can be a guide pulley or a guide tube. The annealing device outputs the annealed wire, which is then fed into the wire drawing device via a guide mechanism for the drawing step. The control device is used to monitor and control the annealing and drawing process.

[0032] For example, the control device can be a mobile phone, a tablet computer, a laptop computer, an ultra-mobile personal computer (UMPC), a netbook, a smart screen, a smart TV, a handheld device with wireless communication function, a desktop computer, a handheld device with wireless communication function, a computer, a laptop computer, a handheld computing device, etc.

[0033] In order to better understand the continuous operation control method of the annealing and drawing machine provided in the embodiment of the present application, the specific implementation process of the continuous operation control method of the annealing and drawing machine provided in the embodiment of the present application is exemplarily introduced below.

[0034] Figure 1 and Figure 2 A schematic flow chart of the continuous operation control method of the annealing and drawing machine provided in the embodiment of the present application is shown. Figure 1 and Figure 2 , the continuous operation control method of the annealing and drawing machine includes: S100, obtaining annealing parameters and drawing length; wherein, the annealing parameters are used to reflect the setting parameters for annealing the wire, and the drawing length is used to reflect the length of the wire between the completion of the annealing stage and the entry into the drawing stage in the annealing and drawing machine.

[0035] It is understood that annealing parameters include annealing speed and annealing current. Annealing current refers to the current flowing through the power supply device into the conductive circuit when the wire and the conductive brush form a complete conductive circuit. Annealing speed refers to the speed at which the wire is transported during annealing.

[0036] For example, annealing parameters and wire drawing length can be manually input. Annealing parameters and wire drawing length can also be directly obtained through a historical database. A historical database is a database containing annealing parameters corresponding to different wire annealing requirements and the wire drawing length of the initially set wire drawing device. This data can be obtained through laboratory experiments, on-site measurements and monitoring, and past experience. Once obtained, the collected data is organized, classified, and archived to extract useful information and patterns. The relevant data is then saved in a database to form a historical database.

[0037] S200, based on an annealing operation corresponding to the annealing parameters, first temperature information is acquired in real time at a first position after a first timing, and second temperature information is acquired in real time at a second position after a second timing; wherein the first position is used to reflect a non-end point position of a heating stage when annealing the wire rod, and the second position is used to reflect an end point position of the heating stage when annealing the wire rod.

[0038] It can be understood that the non-endpoint position refers to the position in the circuit formed by the wire and the conductive brush during the heating phase, which is not the set position of the conductive brush. The direction from the first position to the second position is the transmission direction of the wire. The end position is the position where the wire leaves the heating phase.

[0039] For example, when the wire is annealed according to the set annealing parameters, when it is detected that the wire and the conductive brush form a complete circuit, a signal is sent to the device, indicating that it is now possible to start acquiring the second temperature information in real time at the second position. Then, the annealing parameters and the information of the wire's own property characteristics are analyzed to obtain a temperature change image of the wire when the wire is tested under the annealing parameters. Then, when the second temperature information is monitored in real time and reaches the maximum temperature in the temperature change graph, a signal is sent to the device, indicating that it is now possible to start acquiring the first temperature information in real time at the first position.

[0040] In one possible implementation, in step S200, based on an annealing operation corresponding to an annealing parameter, first temperature information is acquired in real time at a first position after a first timing, and second temperature information is acquired in real time at a second position after a second timing, including: S210, when the detection signal is triggered, the triggering timing is confirmed as the second timing, and second temperature information is obtained in real time at the second position after the second timing; wherein the detection signal is used to reflect the signal emitted when the wire and the conductive brush form a complete circuit when annealing the wire.

[0041] It can be understood that the wire starts to be heated only when a complete circuit is formed between the wire and the conductive brush.

[0042] For example, if the wire takes 3 seconds to form a complete loop after entering the annealing equipment, the annealing equipment and the wire cannot form a complete loop before 3 seconds, and thus no temperature change can occur, and so on.

[0043] S220, obtaining wire material information; wherein the wire material information is used to reflect the material grade and wire diameter of the produced wire material.

[0044] As you can understand, a material grade is a specific symbol or code used to identify and distinguish metal materials of different types, compositions, properties, and uses. Wire diameter refers to the diameter of the wire. Wire information can be obtained manually. Alternatively, wire information can be directly obtained through a production diary. A production diary is a document or management tool that records various parameters of the resulting wire during the production process. The production diary includes the material grade and wire diameter parameters of the produced wire.

[0045] S230 , analyzing the wire material information, the annealing parameters, and the second temperature information to obtain a first timing of the first temperature information, and acquiring the first temperature information in real time at the first position after the first timing.

[0046] It can be understood that the wire information and annealing parameters can be analyzed to obtain a graph of the temperature change of the wire when the wire is annealed under the annealing parameters, and then the maximum temperature value in the graph is extracted as the trigger target. When the second temperature information is compared with the maximum temperature value and is equal to it, the acquisition signal of the first temperature information is triggered, which is the second opportunity.

[0047] With this setting, by detecting the trigger signal (second timing) that the wire and the conductive brush form a complete circuit, combined with the wire material properties (brand, wire diameter) and preset annealing process parameters, a comprehensive analysis is performed using the second temperature information collected in real time, thereby accurately determining the control timing of the first temperature information.

[0048] In one possible implementation, in step S230, analyzing the wire material information, the annealing parameters, and the second temperature information to obtain a first timing of the first temperature information, and acquiring the first temperature information in real time at the first position after the first timing, includes: S231 , performing simulation analysis based on the wire material information and the annealing parameters to obtain a reference temperature change curve; wherein the reference temperature change curve is used to reflect a graph of the temperature change of the wire material when the wire material is annealed under the annealing parameters.

[0049] For example, annealing parameters and wire material information can be input and solved using professional simulation software (such as ANSYS or COMSOL) to obtain the wire material temperature data during the heating phase. Finally, the simulation results are processed to extract the temperature information of key nodes. A curve is plotted with time as the horizontal axis and temperature as the vertical axis, thereby generating a reference temperature change curve reflecting the wire material temperature change under the annealing parameters. The calorific value can also be calculated for the known wire material information based on the set annealing parameters, and then a curve of the wire material temperature change over time during the heating phase can be obtained based on the relationship between the thermal energy formula and the temperature change.

[0050] S232 , analyzing the reference temperature change curve to obtain a target temperature; wherein the target temperature is used to reflect the maximum temperature value in the reference temperature change curve.

[0051] It can be understood that the maximum temperature value can be found in the reference temperature variation curve and the maximum temperature value can be confirmed as the target temperature.

[0052] S233: Confirm the timing when the second temperature information is equal to the target temperature as the second timing.

[0053] It can be understood that when the second temperature information is equal to the target temperature, a start signal is sent to the first detection device, and the first detection device at the first position starts to obtain the first temperature information.

[0054] This setup simulates and calculates wire material properties (such as grade and diameter) against pre-set annealing parameters to generate a theoretical temperature curve. Key process parameters (such as maximum temperature) are then extracted from this curve as a target temperature benchmark. Subsequently, by monitoring the actual temperature data during the annealing process (secondary temperature information) in real time, when it reaches the predicted target temperature, it is determined to be the critical moment for achieving the process requirements (secondary timing), providing foundational data for subsequent analysis.

[0055] S300 , analyzing the first temperature information and the second temperature information to obtain an annealing status chain; wherein the annealing status chain is used to reflect a timing chain of different annealing conditions corresponding to different wire lengths of the wire.

[0056] Exemplarily, the time reflecting the time when the wire reaches the first position from the starting position of the heating stage can be first obtained, and then the time can be matched with the reference temperature change graph to obtain the temperature value corresponding to the time point in the reference temperature change graph. Then, the temperature value can be compared with the first temperature information to obtain two results, including that the first temperature information is equal to the temperature and that the first temperature information is not equal to the temperature. Then, based on these two results, multiple virtual segments are obtained to reflect the different annealing conditions at different positions on the wire. Then, through analysis of the two comparison results, the first temperature information and the second temperature information, a set of temperature change graphs corresponding to the multiple virtual segments on the wire is obtained. Finally, the set of temperature change graphs corresponding to the multiple virtual segments on the wire is matched and combined with the multiple virtual segments to obtain an annealing condition chain.

[0057] In a possible implementation, in step S300, analyzing the first temperature information and the second temperature information to obtain an annealing status chain includes: S310, obtaining a first time, and matching the first time with a reference temperature change curve to obtain a matching temperature at the first time in the reference temperature change curve, and determining the matching temperature as a comparison temperature; wherein the first time is used to reflect the time when the wire reaches the first position from the starting position of the heating stage, and the comparison temperature is used to reflect the temperature at the first time in the reference temperature change curve.

[0058] It is understood that the first time can be obtained by first obtaining the distance value from the starting position to the first position, and then processing the annealing speed in the annealing parameter and the distance value to obtain the first time. The starting position is the position where the wire enters the heating stage.

[0059] S320 , comparing the first temperature information with the comparison temperature to obtain a comparison result; wherein the comparison result includes that the first temperature information is equal to the comparison temperature and that the first temperature information is not equal to the comparison temperature.

[0060] It can be understood that when the comparison result shows that the first temperature information is equal to the comparison temperature, it can be understood that during the heating phase, when a point on the wire was transferred from the starting position to the first position, no contact fluctuation occurred between the wire and the conductive brush. Conversely, when the comparison result shows that the first temperature information is not equal to the comparison temperature, it can be understood that during the heating phase, when a point on the wire was transferred from the starting position to the first position, contact fluctuation occurred between the wire and the conductive brush. During the period when a point on the wire was transferred from the starting position to the first position, the wire corresponding to that period will have exited the heating phase. In other words, by analyzing the contact fluctuation generated during the heating phase, the temperature change of the wire after leaving the heating phase can be analyzed.

[0061] S330 , analyzing the comparison results to obtain a plurality of annealing segments, wherein the annealing segments are virtual segments used to reflect different annealing conditions at different locations on the wire.

[0062] It can be understood that virtual segmentation refers to distinguishing segments of the wire that have different temperature change conditions. For example, the boundaries between different segments can be marked, or the wire can be virtually segmented through a sequence chain of length values.

[0063] For example, the comparison results can be analyzed to obtain a chain composed of time points reflecting that the first temperature information is equal to the comparison temperature, and a chain composed of time points reflecting that the first temperature information is not equal to the comparison temperature, and then the nodes are matched by these two chains to finally obtain a cyclic sequence reflecting that the comparison results go from equal to unequal and then to equal, and then the wire is virtually segmented according to the cyclic sequence.

[0064] The comparison results can also be analyzed to obtain the time point at which the comparison result reflects that the first temperature information is not equal to the comparison temperature, and then the analysis is performed based on this time point to obtain the time point at which the comparison result reflects that the first temperature information is equal to the comparison temperature next time, and then the analysis is performed based on this time point to obtain the time point at which the comparison result reflects that the first temperature information is not equal to the comparison temperature next time, and so on, so as to obtain multiple time points, and then virtually segment the wire based on multiple time points.

[0065] In one possible implementation, in step S330, analysis is performed based on the comparison results to obtain multiple annealing segments, including: S331, analyze according to the comparison result to obtain an equal time chain and an unequal time chain; wherein the equal time chain is used to reflect the chain composed of time points when the first temperature information is equal to the comparison temperature in time sequence, and the unequal time chain is used to reflect the chain composed of time points when the first temperature information is unequal to the comparison temperature in time sequence.

[0066] For example, the comparison results can be analyzed to obtain multiple time points at which the first temperature information reflected in the comparison results is equal to the comparison temperature, and then the multiple time points are processed according to a time series to obtain an equal time chain, and multiple time points at which the first temperature information reflected in the comparison results is unequal to the comparison temperature are obtained, and then the multiple time points are processed according to a time series to obtain an unequal time chain.

[0067] S332 , performing node matching according to the equal time chain and the unequal time chain to obtain a cyclic result chain; wherein the cyclic result chain is used to reflect the cyclic order of the comparison results from equal to unequal and then to equal.

[0068] It can be understood that the temperature change is caused by the contact fluctuation between the wire and the conductive brush, that is, the comparison result transitions from equal to unequal at the beginning, and then from unequal to equal, that is, the cyclic result chain is a cyclic sequence of comparison results from equal to unequal and then to equal.

[0069] For example, the time nodes in the equal time chain and the time nodes in the unequal time chain can be processed according to the time size to obtain multiple time periods, and then the multiple time periods can be processed in time sequence to obtain a circular result chain. Alternatively, the circular result chain can be directly obtained by directly extracting the time points at which the comparison results changed from the comparison results and arranging the time points in time sequence.

[0070] In a possible implementation, in step S332, node matching is performed based on the equal time chain and the unequal time chain to obtain a circular result chain, including: S3321: Combine the time nodes in the equal time chain with the time nodes in the unequal time chain to obtain multiple time periods.

[0071] For example, if the equal time chain is 3s-6s-7s-10s and the unequal time chain is 4s-6.4s-8s-11s, then the first time period in the multiple time periods is the time period composed of the first time node (3s) in the equal time chain and the first time node (4s) in the unequal time chain, that is, (3s, 4s), the second time period in the multiple time periods is the time period composed of the first time node (4s) in the unequal time chain and the second time node (6s) in the equal time chain, that is, (4s, 6s), and so on.

[0072] S3322, processing is performed according to the time sequence of multiple time periods to obtain a circular result chain.

[0073] It can be understood that multiple time periods are sorted according to the time size to obtain a circular result chain.

[0074] For example, if the multiple time periods are (3s, 4s), (4s, 6s), (6s, 6.4s), (6.4s, 7s), then the loop result chain is (3s, 4s)-(4s, 6s)-(6s, 6.4s)-(6.4s, 7s), and so on.

[0075] With this setting, by aligning and fusing the time axes of equal time chains with regular intervals and unequal time chains with irregular intervals, a composite time structure consisting of multiple discrete time periods is constructed. Subsequently, dynamic processing is performed based on the temporal correlation of these time periods, and finally a result chain with cyclic characteristics is generated, which can provide prompts on the time points when contact fluctuations occur, and can also segment the different temperature changes of the wire according to the chain to provide segmentation conditions.

[0076] S333, performing virtual segmentation processing on the wire based on the cycle result chain to obtain multiple annealing sections.

[0077] It can be understood that the multiple time periods in the cycle result chain can be processed according to the transmission speed of the wire during the heating process to obtain multiple length values ​​corresponding to the multiple time periods, and then the wire can be virtually segmented according to the multiple length values ​​to obtain multiple annealing sections.

[0078] In this way, by comparing the difference between the first temperature information and the target temperature, the key time nodes of equal and unequal temperatures are extracted, and an equal time chain (temperature stable interval) and an unequal time chain (temperature fluctuation interval) are constructed respectively to form a two-dimensional time series representation of temperature changes. The nodes of the two types of time chains are matched and correlated, and a cyclic result chain reflecting the "equal→unequal→equal" cycle characteristics of temperature is constructed. The changing law of contact fluctuations during the annealing process and the random occurrence time points of contact fluctuations are recorded. The wire is virtually segmented based on the cyclic result chain, and the continuous annealing process is divided into multiple annealing segments with specific temperature behavior characteristics, which can provide a basis for the subsequent dynamic adaptation and refined control of the tension control of the wire drawing device.

[0079] S340 , analyzing the comparison result, the first temperature information, and the second temperature information to obtain an annealing temperature variation atlas; wherein the annealing temperature variation atlas is used to reflect a set of temperature variation graphs corresponding to the annealing sections on the wire.

[0080] It can be understood that the time for reflecting the time when the wire reaches the second position from the starting position of the heating stage can be obtained, and then the temperature change graph for reflecting the first annealing section when the wire is annealed can be obtained from the second temperature information based on the time. Then, analysis can be performed based on the comparison result to obtain change characteristics including the number of times the comparison result changes, the change nodes at the time points when the changes occur, and the change span from the time of change to the next change. Then, based on the change characteristics, analysis is performed based on the temperature change graph of the first annealing section, the first temperature information, and the second temperature information to obtain an atlas reflecting the annealing temperature change graph and the temperature change graph of the first annealing section. Finally, the temperature change graph of the first annealing section and the atlas are matched to generate an annealing status chain.

[0081] A subsequent temperature change atlas can also be obtained through the learning model, that is, the initial temperature change graph, the first temperature information, and the second temperature information are input into the learning model, and the learning model then outputs the corresponding subsequent temperature change atlas. The training process of the learning model can be performed by using the data obtained after data processing of the initial temperature change graph, the first temperature information, the second temperature information, and the corresponding subsequent temperature change atlas as the training data set of the learning model, and then inputting the training data set of the learning model into the learning model for training and learning, and finally obtaining the learning model. After obtaining the subsequent temperature change atlas, it is analyzed based on the second temperature information to obtain the temperature change graph of the first annealing section, and finally the annealing temperature change atlas is formed by combining the temperature change graph of the first annealing section with the subsequent temperature change atlas.

[0082] In a possible implementation, in step S340, an annealing temperature variation atlas is obtained based on the comparison result, the first temperature information, and the second temperature information, including: S341, obtaining a second time, and obtaining an initial temperature change graph in the annealing temperature change graph set from the second temperature information according to the second time; wherein the second time is used to reflect the time when the wire reaches the second position from the starting position of the heating stage, and the initial temperature change graph is used to reflect the temperature change graph of the first annealing section when annealing the wire.

[0083] It is understood that the second time can be obtained by first obtaining the distance value from the starting position to the second position, and then processing the distance value with the annealing speed in the annealing parameters. Because the set distance of the second position is manually set, the distance between the starting position and the second position is known. The initial temperature change graph refers to the temperature change graph of the wire from the time the second temperature information is obtained to the second time.

[0084] S342, analyzing the comparison results to obtain a change status; wherein the change status includes a change node used to reflect the number of times the comparison results have changed, the time point when the change occurred, and the change span from the change to the next change.

[0085] It can be understood that the analysis process of the change status can be analyzed through the comparison results. When the comparison result changes, the number of changes and the time point of the change are recorded. Because the first temperature information is monitored in real time, when the comparison result changes, the time point can be recorded. The change span can be the time period between the change of the comparison result and the next change of the comparison result, that is, the corresponding time period in the loop result chain in step S3322.

[0086] S343 , based on the change condition, analyzing the initial temperature change graph, the first temperature information, and the second temperature information to obtain a subsequent temperature change atlas; wherein the subsequent temperature change atlas is used to reflect the annealing temperature change atlas after removing the initial temperature change graph.

[0087] Exemplarily, the maximum temperature can be obtained from the second temperature information through the change span in the change condition, and the temperature change trend reflecting the change condition in the i-th annealing section when the change condition changes can be obtained from the first temperature information through the change span in the change condition. Then, analysis is performed based on the maximum temperature and the change trend to obtain a temperature change graph reflecting the change condition of the i-th annealing section after the change condition changes. Then, based on the number of changes reflected by the change condition, the initial temperature change graph and the subsequent temperature change graph set are processed respectively according to the change nodes in the change condition to obtain a temperature change graph reflecting that the i-th annealing section has started annealing but the change condition has not changed. Finally, the temperature change graph reflecting that the i-th annealing section has started annealing but the change condition has not changed and the temperature change graph reflecting that the i-th annealing section has changed after the change condition changes are processed according to time nodes to obtain multiple subsequent temperature change graphs. Finally, the multiple subsequent temperature change graphs are processed again to obtain a subsequent temperature change graph set.

[0088] A subsequent temperature change atlas can also be obtained through the learning model. That is, the initial temperature change graph, the first temperature information, and the second temperature information are input into the learning model, and the learning model then outputs the corresponding subsequent temperature change atlas. The training process of the learning model can use the data obtained after data processing of the initial temperature change graph, the first temperature information, the second temperature information, and the corresponding subsequent temperature change atlas as the training data set of the learning model, and then input the training data set of the learning model into the learning model for training and learning, thereby finally obtaining the learning model.

[0089] In one possible implementation, in step S343, based on the change condition, analysis is performed according to the initial temperature change graph, the first temperature information, and the second temperature information to obtain a subsequent temperature change graph set, including: S3431, obtaining a maximum temperature value from the second temperature information according to the change span in the change condition, and obtaining a change trend from the first temperature information; wherein the change trend is used to reflect the temperature change trend when the change condition in the i-th annealing section changes.

[0090] It can be understood that the change span is a time span, and the maximum temperature value is obtained by real-time monitoring of the second temperature information and the maximum value reached by the temperature in the time span. The change trend refers to the temperature change rate of the first temperature information in the first temperature information within the time span.

[0091] S3432, processing is performed based on the change trend and the maximum temperature value to obtain a second change graph; wherein the second change graph is used to reflect the temperature change graph of the i-th annealing section after the change condition changes.

[0092] It can be understood that the change trend is the temperature change trend over a time span. The change trend is obtained by analyzing the change span in the change condition. That is, the change trend is the process change of temperature change, and the maximum temperature value is the result of the process change through the temperature change. That is, the second change graph can be directly drawn through the maximum temperature value and the change trend.

[0093] S3433: When the change status reflects the first change in the comparison result, the initial temperature change graph is processed according to the change node in the change status to obtain a first change graph; wherein the first change graph is used to reflect the temperature change graph of the i-th annealing stage after the annealing change status has begun but has not changed.

[0094] It can be understood that when the change reflects the first change in the comparison results, it indicates that the wire experienced its first stress release during the annealing process, causing the first contact fluctuation between the wire and the conductive brush. When this first contact fluctuation occurs, the point where the contact fluctuation occurs has just entered the heating phase. Correspondingly, there is a section of the wire that has just left the heating phase. The temperature change curve of this section of wire, when no contact fluctuation occurs, is the temperature change graph of the chef's temperature change graph after the change node. The shape of the first change graph is the same as the trend graph after the change node in the initial temperature change graph, and the starting point of the first change graph is the wire temperature just after entering the heating phase.

[0095] For example, if the change node is 3s, the trend graph after 3s in the initial temperature change graph is used to draw the first change graph with the wire temperature just entering the heating stage as the starting point, and so on.

[0096] In a possible implementation, in step S3433, based on the change condition, the initial temperature change graph, the first temperature information, and the second temperature information are analyzed to obtain a subsequent temperature change graph set, further comprising: S34331, when the change status reflects that the comparison result has changed for the i-th time, the i-1-th temperature change graph in the subsequent temperature change graph set is processed according to the change node in the change status to obtain the first change graph; wherein, i is greater than 1, and the change node is used to reflect the time point when the comparison result changes.

[0097] It can be understood that when the comparison result changes for the i-th time, the analysis process of the first change graph can be obtained by processing the initial temperature change graph according to the change node in a similar manner to step S3433 when the comparison result changes for the first time to obtain the first change graph, which will not be repeated here.

[0098] S34332: Process the first change graph and the second change graph to obtain an i-th temperature change graph in subsequent temperature change graphs.

[0099] It can be understood that the first change graph described above is the temperature change of the wire that has just left the heating stage and just entered the heating stage when the comparison result has the i-th change. The second change graph described above is the temperature change after the contact fluctuation occurs when the comparison result has the i-th change and the wire has not yet left the heating stage. By combining the first change graph and the second change graph in time sequence, the i-th temperature change graph in the subsequent temperature change graph is finally obtained.

[0100] S34333, confirming the plurality of subsequent temperature change graphs as a subsequent temperature change graph set.

[0101] It can be understood that the processing process of the subsequent temperature change atlas is to arrange and combine multiple subsequent temperature change graphs in time sequence to form an atlas, or to arrange and combine multiple subsequent temperature change graphs in the order in which they are obtained to form an atlas.

[0102] With this setting, by analyzing the changes in comparison results at different times, the temperature change of the next annealing section is analyzed based on the temperature change diagram of the previous annealing section to generate a temperature change diagram corresponding to the annealing section. Through segmented modeling and dynamic feature extraction, the annealing process can be transformed from "experience-driven" to "data-driven", which significantly improves the process robustness and material performance consistency under complex working conditions.

[0103] S3434: Process the first change graph and the second change graph to obtain an i-th temperature change graph in subsequent temperature change graphs.

[0104] It can be understood that the processing process of the i-th temperature change graph is the same as the processing process of step S34332.

[0105] S3435, confirming the multiple subsequent temperature change graphs as a subsequent temperature change graph set.

[0106] It can be understood that the subsequent process of obtaining the temperature change atlas is the same as the processing process of step S34333.

[0107] S344, confirming the initial temperature change graph and the subsequent temperature change graph set as an annealing temperature change graph set.

[0108] It can be understood that the initial temperature change graph set is the first temperature change graph in the annealing temperature change graph set. The initial temperature change graph is directly set before the first temperature change graph in the subsequent temperature change graphs, which is the annealing temperature change graph.

[0109] With this setup, by obtaining the arrival time (second time) of the wire at a key position (second position) during the heating phase and combining it with the temperature change graph of the initial annealing section (initial temperature change graph), a mapping relationship between time and temperature behavior is established, providing a benchmark for subsequent staged modeling. Based on the comparison results (such as the difference between the first and second temperature information), the dynamic characteristics of the annealing process are extracted, including the frequency (number) of temperature changes, key turning points (change nodes), and the duration (change span) of the changes, forming a quantitative description of the evolution of temperature behavior. The initial temperature change graph and the subsequent graph set are combined into a complete annealing temperature change atlas, forming a temperature behavior database covering the entire annealing process.

[0110] S350 , generating an annealing status chain based on corresponding matching between the plurality of annealing sections and the plurality of annealing temperature variation graphs.

[0111] It can be understood that the annealing condition chain refers to a feature chain including multiple annealing sections and multiple annealing temperature change graphs corresponding to the multiple annealing sections. That is, when the wire leaves the heating stage, the wire has multiple virtual segments, which divide the wire into multiple annealing sections, and each of the multiple annealing sections corresponds to an annealing temperature change graph.

[0112] This setup captures the arrival time (first time) of the wire at key locations during the heating phase. Combined with a preset reference temperature curve, the corresponding comparison temperature is accurately extracted as a baseline value. This is then dynamically compared with the actual monitored temperature data (first temperature information) to identify equal and different temperature behavior states. Based on this comparison, the wire is divided into multiple virtual annealing sections with specific temperature characteristics. By integrating the first temperature information with the real-time collected second temperature information, a temperature variation atlas covering each annealing section is constructed. Ultimately, the annealing sections are mapped to their corresponding temperature variation graphs, generating an annealing status chain that reflects the entire lifecycle of the annealing process.

[0113] S400: Processing the annealing status chain and the wire drawing length to obtain a wire drawing adjustment strategy. The wire drawing adjustment strategy is used to reflect the tension change strategy of the wire drawing device of the annealing wire drawing machine on the wire after annealing.

[0114] It can be understood that, since the drawing length is fixed, as the drawing progresses, the annealing condition chain within the drawing length changes, that is, the tension on the wire in the drawing device also changes accordingly.

[0115] For example, the annealing condition chain can be used for analysis to obtain the hardness values ​​of the wire in different annealing sections, and then the annealing condition chain can be matched with the parallel wire length to obtain the wire length included in the parallel wire length, and the wire length corresponds to multiple hardness values. Then, based on the hardness values ​​included in the parallel wire length, analysis is performed to obtain the tension range of the hardness values ​​included in the parallel wire length, and then the length of the annealing section included in the parallel wire length is analyzed to obtain the weight values ​​corresponding to different annealing sections. Finally, processing is performed based on the weight value and the tension range to obtain the parallel wire adjustment strategy.

[0116] Drawing force can also be derived through an analytical model. This involves inputting the annealing condition chain and the drawing length into the analytical model, which then outputs the corresponding drawing force. The analytical model training process can be performed by processing the data from the annealing condition chain, drawing length, and corresponding drawing force into a training dataset for the analytical model. This training dataset is then input into the analytical model for training and learning, ultimately yielding the analytical model.

[0117] With such a setting, the annealing condition chain associated with the wire hardness is obtained by analysis, and then the annealing condition chain associated with the material hardness is analyzed with the wire drawing tension in the wire drawing process, and the wire drawing tension is adjusted in real time according to the annealing condition chain. This can improve the matching degree between the drawing force of the wire drawing device and the wire strength, increase the correlation between the drawing force of the wire drawing device and the strength of the wire, increase the uniformity of the wire arrangement, and reduce the risk of wire breakage in the wire drawing process.

[0118] In a possible implementation, in step S400, processing is performed based on the annealing status chain and the length of the parallel wire to obtain a parallel wire adjustment strategy, including: S410 , simulating grain growth conditions according to the annealing temperature variation diagram in the annealing condition chain to obtain hardness values ​​corresponding to the temperature variation diagram; wherein the hardness values ​​are used to reflect the hardness of the wire at different positions.

[0119] It can be understood that the different annealing temperature variation diagrams of the wire in the heating stage correspond to the grain growth conditions inside the wire.

[0120] For example, the temperature-time curve can be analyzed by thermal analysis software to extract parameters such as heating rate and peak temperature. Based on the grain growth kinetics model (such as Johnson-Mehl-Avrami equation or Burke-Laughlin model), the evolution of grain size with temperature can be simulated to quantify the average grain diameter or grain size grade. Subsequently, the correlation model between material hardness and grain size (such as Hall-Page formula H=H0+k×d −1 / 2, where d is the grain diameter, H0 and k are material constants), the simulated grain size sequence is substituted into the graph to calculate the hardness value corresponding to the annealing temperature variation diagram.

[0121] S420, performing matching analysis based on the annealing condition chain and the wire drawing length to obtain a plurality of inclusive hardnesses and a plurality of matching annealing segments; wherein the inclusive hardness is used to reflect the hardness value of the annealing segment included in the wire drawing length, and the matching annealing segment is used to reflect the annealing segment included in the wire drawing length.

[0122] For example, if there are three different annealing sections, the length of the first annealing section is 1m, the length of the second annealing section is 2m, and the length of the third annealing section is 2m. If the wire drawing length is 3m, the matching annealing sections are the first annealing section of 1m and the second annealing section of 2m. If the wire drawing length is 4m, the matching annealing sections are the first annealing section of 1m, the second annealing section of 2m, and the third annealing section of 1m, and so on.

[0123] S430 , performing analysis based on the enclosed hardness to obtain a tension interval corresponding to the enclosed hardness; wherein the tension interval is used to reflect a tension range corresponding to the enclosed hardness.

[0124] For example, a standardized hardness test (such as Rockwell HRC or Brinell HB) is used to measure the hardness of the wire rod. A tensile test is then performed simultaneously to obtain the corresponding tension parameters. The theoretical tension value is then adjusted downward based on a confidence interval or safety factor (typically 1.5-2.0), thereby defining a safe tension range and constructing a tension database. A tension database is a database containing the tension ranges corresponding to different hardness levels. This data can be obtained through laboratory experiments, field measurements and monitoring, and past experience. Once collected, the data is organized, categorized, and archived to extract useful information and patterns. The relevant data is then stored in a database to form the tension database.

[0125] S440 , performing processing according to the lengths of the plurality of matching annealing segments to obtain weight values ​​corresponding to the plurality of matching annealing segments.

[0126] It can be understood that the weight value can be obtained by the ratio of the length values ​​of multiple matching annealing sections to the length of the parallel wire.

[0127] For example, if the length of the parallel wire is 4m and the first matching annealing section is 1m, the weight of the matching annealing section is 0.25 (1÷4); the second matching annealing section is 2m, the weight of the matching annealing section is 0.5 (2÷4), and so on.

[0128] S450: Process the multiple tension intervals based on the multiple weight values ​​to obtain a parallel yarn adjustment strategy.

[0129] For example, multiple tension intervals can be analyzed to obtain medians corresponding to the multiple tension intervals, and then the medians and corresponding weight values ​​can be processed to obtain the tension value of the winding device. Alternatively, multiple tension intervals can be processed to obtain a union of multiple tension intervals, and then the weight value of the tension interval to which the left limit belongs is obtained based on the tension interval to which the left limit belongs. At the same time, the weight value of the tension interval to which the right limit belongs is obtained based on the tension interval to which the right limit belongs. Finally, a weighted sum is performed based on the left limit value of the union and the weight value of the tension interval to which the left limit belongs, and the right limit value and the weight value of the tension interval to which the right limit belongs, to finally obtain the tension value of the winding device.

[0130] With this setup, the grain growth process is simulated through the temperature change diagram of each annealing section in the annealing condition chain, the hardness distribution at different positions is quantified, and a mapping relationship between the material microstructure (grain size) and the macroscopic properties (hardness) is established; then the hardness characteristics are coupled and matched with the wire drawing length, and the corresponding annealing section hardness combination (including hardness) under each wire drawing length is extracted, and the tension range is derived based on the physical correlation between hardness and tension; further, the weight of the annealing section length is calculated (the longer the section, the higher the weight), and the multiple groups of tension ranges are weighted and fused, and finally a tension adjustment strategy for different wire drawing lengths is generated, realizing dynamic adaptation from heat treatment process to wire drawing parameters.

[0131] In one possible implementation, in step S450, multiple tension intervals are processed based on multiple weight values ​​to obtain a parallel yarn adjustment strategy, including: S451: Processing is performed based on the multiple tension intervals to obtain multiple median tensions; wherein the median tension is used to reflect the median of the tension intervals.

[0132] It can be understood that the median tension is the average value between the left limit value and the right limit value of the tension range.

[0133] S452: Processing is performed based on the multiple weight values ​​and the multiple median tensions to obtain a parallel yarn adjustment strategy.

[0134] It can be understood that if there are three tension intervals, the parallel yarn tension = first median tension × first weight + second median tension × second weight + third median tension × third weight.

[0135] It should be understood that the size of the serial numbers of the steps in the above embodiments does not mean the order of execution.
