Description

Technical Field

[0001] The present application relates to the technical field of acid continuous rolling, and in particular to a defect tracking method and related equipment for an acid continuous rolling production line. Background Art

[0002] In the pickling continuous rolling production line, various defects may exist on the surface of the strip after pickling and mill operation, such as inclusions, slag and edge cracks, etc. These defects may have adverse effects on the rolling process, such as damaging the rolls and even causing serious problems such as strip breakage.

[0003] At present, the identification and tracking of surface defects of strip steel in the pickling continuous rolling production line mainly rely on manual observation, which requires the collaboration of at least two people: one person in the pickling inspection room to check the actual defects, and the other person to operate the strip steel for inching control. However, the strip steel enters the exit inspection table from the entrance uncoiler, passing through the straightening machine and the acid tank in the middle, and the exit inspection table is far away from the front of the rolling mill, making it difficult to accurately confirm the location of the defect. The whole process is not only time-consuming and labor-intensive, but also lacks real-time position tracking data, and cannot accurately control the defect location, which makes it easy for defects to enter the rolling mill, affecting production efficiency and quality. Therefore, there is an urgent need for a defect tracking method for the pickling continuous rolling production line. Summary of the invention

[0016] In a feasible implementation, it also includes:

[0017] Based on the inching movement handle in the pickling operation room, the movement of the strip is accurately controlled, wherein the inching movement handle includes a locking function, a forward inching function and a backward inching function.

[0019] The pickling operation room is taken as the origin of the strip and the mill entrance stand is taken as the end point. Based on the tension roller, the position of the strip is tracked in real time, and the distance between the marked position and the mill entrance is calculated.

[0020] In one possible implementation,

[0021] The above-mentioned response strategy for the above-mentioned defect based on the marked position and the mill entrance position on the above-mentioned acid continuous rolling production line includes:

[0022] When the distance between the marked position and the mill entrance position on the above-mentioned acid continuous rolling production line is zero,

[0023] In the case where the above-mentioned defect is of the first defect type, controlling the rolling mill to perform empty coil operation; or,

[0024] In the case where the defect is of the second defect type, the rolling mill is controlled to perform the rolling operation of the strip at a speed greater than or equal to a third preset speed and less than or equal to a fourth preset speed.

[0025] In a second aspect, the present application proposes a defect tracking device for an acid continuous rolling production line, comprising:

[0026] An information acquisition unit, used to acquire the running speed of the steel strip and defect information on the surface of the steel strip;

Specifically, the present invention calculates the position of the defect on the strip by the running speed of the strip and the defect information, and accurately marks the position. This process not only overcomes the error caused by manual observation, but also makes the identification and positioning of the defect more accurate. In addition, through the real-time defect tracking function, the system can dynamically adjust the corresponding control strategy based on the position of the defect in the production line. When the defect approaches the entrance of the rolling mill, different response operations are automatically triggered according to the severity of the defect: for serious defects, the system will automatically stop to avoid damage to the roll or strip breakage; and for minor defects, the system will adjust the rolling speed to a preset safe speed, thereby ensuring the continuity of production and the safety of the production line. Compared with the traditional two-person collaboration mode, the present invention also designs a strip inching moving handle, so that a single person can complete the defect search task, which not only greatly reduces the labor intensity, but also makes the entire process smoother and more efficient. In addition, by automatically controlling the running speed of the head and tail parts of the strip and dynamically displaying the defect position in the operating room, the operator can intuitively grasp the distance of the defect relative to the rolling mill and take timely treatment measures, effectively reducing the dependence on manual experience. In short, the present invention not only simplifies the defect handling process, but also significantly improves the automation level and production efficiency of the acid continuous rolling production line, reduces the need for manual intervention, and at the same time reduces production costs and safety risks, providing a guarantee for the stability and reliability of production.

It should be understood that the data used in this way can be interchangeable where appropriate, so that the embodiments described here can be implemented in an order other than the content illustrated or described here.

The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all of the embodiments.

[0037] See also Figure 1 , which is a flow chart of a defect tracking method for a pickling continuous rolling production line provided in an embodiment of the present application, which may specifically include:

[0038] S110, obtaining the running speed of the steel strip and the defect information on the surface of the steel strip;

[0039] For example, the acquisition of running speed mainly depends on the speed sensor on the production line, which monitors the moving speed of the strip in the acid rolling process in real time and transmits the collected data to the control system. The running speed data of the strip is not only the key input for defect tracking, but also one of the important reference indicators for subsequent defect location calculation and response strategy adjustment. Through accurate speed data, the system can accurately calculate the relative position of defects on the strip and avoid tracking errors caused by speed fluctuations.

[0040] In addition, the defect information on the strip surface is usually collected by a surface detector (surface detector) installed at the strip surface detection position. The surface detector can scan the strip surface with high precision, identify the type, shape, size and other characteristics of the defect through image analysis, photoelectric detection and other methods, and transmit this information to the control system. The acquisition of defect information is the prerequisite for the subsequent tracking and control strategy implementation of the system, ensuring that every detected defect can be accurately located and identified.

[0041] S120, determining the position coordinates corresponding to the defect information on the surface of the steel strip on the steel strip according to the running speed and the defect information, and marking the position coordinates;

[0042] Exemplarily, this process relies on combining real-time speed data with defect detection information to determine the exact position of the defect relative to the origin of the strip. First, the running speed data of the strip provides a time reference for the dynamic movement of the defect on the strip, allowing the system to track the position changes of the strip in the production line. When a defect is detected, by calculating the displacement of the strip in time and combining it with the starting position data, the system can obtain the exact coordinates of the defect relative to the initial position of the strip. This position coordinate determination process is accurate to the millimeter level, ensuring that the system can locate the defect with high precision in the subsequent production process.

[0043] To facilitate subsequent tracking and control, the system will mark the coordinates of the exact location of the defect after determining it. The marking process usually uses a digital coordinate system to associate the defect location with parameters such as the actual strip running distance and the mill entrance position. By displaying the relative distance of the strip defect location on the system interface, the operator can understand the dynamic location of the defect in real time. At the same time, the system stores the defect location mark in the data recording module to associate it with the response strategy in subsequent steps. For example, when the defect location is close to the mill entrance, the system can trigger the corresponding control operation based on the real-time update of the marked position. This position marking function not only improves the visualization of defects, but also provides important data support for the system to perform precise automatic control.

[0044] S130. Based on the marked position and the rolling mill entrance position on the above-mentioned acid continuous rolling production line, a response strategy is executed for the above-mentioned defect.

[0045] Exemplarily, the system automatically executes a preset response strategy based on the relative distance between the defect mark position and the mill entrance position to ensure safe and stable operation of the production line and optimized control of strip quality. Specifically, when a defect is marked by the system and continuously tracked close to the mill entrance, the system determines whether a response operation needs to be triggered by comparing the current position of the defect with the distance to the mill entrance. Different defect types and severities will trigger different control strategies to solve potential problems in a targeted manner. For example, the system pre-classifies defects into two categories: severe defects and mild defects, and sets different response measures.

[0046] In summary, the present invention calculates the position of the defect on the strip by the running speed and defect information of the strip, and accurately marks the position. This process not only overcomes the error caused by manual observation, but also makes the identification and positioning of the defect more accurate. In addition, through the real-time defect tracking function, the system can dynamically adjust the corresponding control strategy based on the position of the defect in the production line. When the defect approaches the entrance of the rolling mill, different response operations are automatically triggered according to the severity of the defect: for serious defects, the system will automatically stop to avoid damage to the roll or strip breakage; for minor defects, the system will adjust the rolling speed to a preset safe speed, thereby ensuring the continuity of production and the safety of the production line. Compared with the traditional two-person collaboration mode, the present invention also designs a strip inching moving handle, so that a single person can complete the defect search task, which not only greatly reduces the labor intensity, but also makes the entire process smoother and more efficient. In addition, through the automatic control of the running speed of the head and tail parts of the strip and the dynamic display of the defect position in the operating room, the operator can intuitively grasp the distance of the defect relative to the rolling mill and take timely treatment measures, effectively reducing the dependence on manual experience. In summary, the present invention not only simplifies the defect handling process, significantly improves the automation level and production efficiency of the acid continuous rolling production line, reduces the need for manual intervention, but also reduces production costs and safety risks, providing a guarantee for the stability and reliability of production.

[0047] In some instances,

[0048] The above position coordinates are determined based on the actual distance and the defect position, wherein the actual distance is the distance from the surface inspection instrument to the preset roller in the pickling inspection room.

[0049] Exemplarily, the system will accurately calculate the relative position coordinates of the defect based on the running speed of the strip and the initial position of the defect detected, combined with the actual physical layout of the pickling continuous rolling production line. The core of this calculation lies in the precise measurement and definition of the "actual distance", where the actual distance is the fixed distance from the surface inspection instrument to a preset roller in the pickling inspection room. The setting of this distance is intended to provide a physical reference so that the position of the defect can be accurately located relative to a fixed reference point. Specifically, as the main tool for defect detection, the surface inspection instrument can accurately capture the location of the surface defects of the strip, but it only relies on the detection position. The exact position of the defect on the strip needs to be further calculated by reference to the actual distance.

[0050] By setting the actual distance, the system can determine the relative position of the defect on the strip according to factors such as the moving speed and elongation of the strip. This process involves using the distance between the defect position initially detected by the gauge and the preset roller position in the pickling inspection room as a reference point to calculate the position change of the strip when it passes through the preset roller, thereby ensuring accurate calculation of the defect position under different production line speeds and elongation conditions. For example, when the defect is a known distance away from a set position of the gauge, the system determines the position of the defect in the pickling inspection room as a fixed relative coordinate through this preset physical distance, combined with the calculation of the strip elongation and the length of the cut head and tail. The determination of this coordinate not only eliminates the error caused by speed fluctuations, but also ensures the stability of the position mark of the defect throughout the process from pickling to the mill entrance.

[0051] The advantage of this method is that defect positioning based on actual distance can mark the position of defects with high precision, so that the defect handling in the entire acid continuous rolling process can be based on accurate data, which not only reduces human errors, but also provides a reliable coordinate basis for real-time tracking of defects and the execution of response strategies. In this way, the system can efficiently manage the position changes of defects, effectively avoid production accidents caused by defects entering the rolling mill, and improve the automation and intelligence level of the production line.

[0052] In some instances,

[0053] The above defect locations are determined based on the following formula:

[0054] Defect location = (planned length - head removal length) × (1 + elongation %)

[0055] Among them, the planned single length is the length of the strip after hot rolling, the strip head cutting length is the defective length of the strip head, and the elongation rate is the length extension ratio of the strip produced by the straightening machine.

[0056] For example, the planned length refers to the overall length of the strip after the hot rolling process is completed. This value is the initial benchmark for the length of the raw material and provides a complete physical reference for the strip. The head cut-off length refers to the length of the head of the strip where there are quality defects or poor surface areas. This part is usually cut off during pickling or subsequent processes, so it needs to be deducted from the total length to ensure that the position calculation is not disturbed by the poor head area.

[0057] Elongation refers to the length extension ratio of the strip when it is processed by the straightening machine. When the straightening machine applies a certain tension to the strip, the length of the strip will be extended to a certain extent, resulting in the actual length of the strip being slightly longer than the initial planned length. The existence of elongation directly affects the position change of defects on the strip, so it is used as a multiplier factor in the position calculation to ensure that the final defect position can be accurately tracked and marked under different extension conditions. Through this correction term in the formula, the system can adapt to different production line speeds and stretching states, and realize dynamic adjustment of the defect position in the acid continuous rolling production line.

[0058] By comprehensively considering the actual physical state of the strip, the calculation of the defect position is not affected by factors such as speed fluctuations and stretch changes during the production process, and always maintains accuracy and reliability. This calculation method ensures the precise positioning of defects, enables the system to obtain the changes in the defect position in real time during the production process, and avoids the position deviation caused by manual observation errors in traditional production.

[0059] In some examples, it also includes:

[0060] When the distance between the head or tail of the strip and the pickling inspection chamber is greater than or equal to the first preset distance and less than or equal to the second preset distance, the running speed of the strip is controlled to be greater than or equal to the first preset speed and less than or equal to the second preset speed.

[0061] Exemplarily, the purpose of this speed adjustment is to ensure that the operator can clearly and accurately inspect and handle the defects on the strip in the pickling inspection room, so as to avoid unclear defect observation or missing key defects due to excessive speed. The control strategy relies on the distance detection during the operation of the strip. When the strip runs to the range of 30 meters (first preset distance) to 40 meters (second preset distance) in front of the pickling inspection room, the system will automatically detect that the strip has entered the safe distance range. At this time, the system will immediately issue an instruction to reduce the speed of the strip to 30 meters / minute (first preset speed)-60 meters / minute (second preset speed). This speed selection is based on a comprehensive consideration of the working efficiency and detection accuracy of the pickling inspection room, ensuring that the strip is at an appropriate moving speed within the field of vision of the operator, so that the personnel can carefully inspect the surface defects of the strip, especially the defects that are prone to appear at the head or tail for efficient processing. In the embodiment of the present application, the first preset distance can be set to 30 meters, the second preset distance can be set to 40 meters, the first preset speed can be set to 30 meters / minute, and the second preset speed can be set to 60 meters / minute.

[0062] In the embodiment of the present application, the distance between the strip and the pickling inspection room is preferably 30 meters, and the running speed of the strip is preferably 60 meters per minute. This speed control strategy is based on the balance between the working efficiency of the pickling inspection room and the defect inspection accuracy, ensuring that the strip is in a suitable running state when entering the key observation range, while ensuring the defect processing efficiency.

[0063] This speed control strategy not only simplifies the operator's tasks, but also greatly improves the accuracy and response speed of defect detection. In addition, by setting the optimal distance of 30 meters, the system can adjust the speed in time before the strip enters the pickling inspection room, avoiding the tedious operation of manual braking or secondary adjustment caused by excessive speed in traditional production lines. At the same time, the system's automatic speed regulation function reduces the need for operator intervention and improves the automation level of the pickling continuous rolling production line.

[0064] In some examples, it also includes:

[0065] Based on the inching movement handle in the pickling operation room, the movement of the strip is accurately controlled, wherein the inching movement handle includes a locking function, a forward inching function and a backward inching function.

[0066] For example, the inching movement handle is a key manual control component, which enables the operator to flexibly and efficiently control the tiny movements of the strip by providing functions such as locking, forward inching, and backward inching, thereby achieving accurate positioning and viewing of strip defects.

[0067] Specifically, the locking function of the inching movement handle allows the strip to be fixed when it moves to a certain position, preventing the strip from sliding or retreating unexpectedly, thereby ensuring that the operator has a stable viewing angle when inspecting and handling defects. The forward inching function allows the operator to gradually move the strip forward while slightly adjusting the strip position, so that the surface defects of the strip can pass through the inspection area of ​​the pickling operation room in turn, making it easier for personnel to inspect every possible defect. The backward inching function provides the ability to fine-tune in the reverse direction, allowing the strip to retreat to its previous position, which is particularly suitable for recalling the strip position when defects are not fully exposed or missed inspection.

[0068] The precise control function of the inching motion handle greatly reduces the labor intensity and difficulty of the operator. In traditional production, it is usually necessary for multiple people to coordinate the operation, one person to perform inching control of the strip, and the other to observe the defects. Through the integration of the inching motion handle, a single person can complete the precise positioning and detection of the strip, which improves the independence of the inspection and the efficiency of operation. At the same time, the precision of this handle control ensures the accuracy of defect inspection, allowing operators to carefully observe the details of the defects and make timely judgments and handle them when the strip is stationary or moving slowly. In general, the inching motion handle of the pickling operation room provides a stable and efficient strip control solution, provides effective support for the reliable detection of defects, and further improves the automation level of the system and the overall efficiency of the production line operation.

[0069] In some examples, it also includes:

[0070] The pickling operation room is taken as the origin of the strip and the mill entrance stand is taken as the end point. Based on the tension roller, the position of the strip is tracked in real time, and the distance between the marked position and the mill entrance is calculated.

[0071] For example, by defining a fixed distance interval between the pickling operation room and the mill entrance, a clear physical reference is provided for the accurate tracking of the strip defect position. During the process of the strip being transported from the pickling operation room to the mill entrance, the system will continuously obtain the strip position data through the tension roller, calculate the real-time distance between the defect position marked on the strip and the mill entrance, and thus dynamically track the actual position of the defect in the production line.

[0072] Through the dynamic position change of the strip between the tension rollers, the system can continuously monitor the conveying speed and position deviation of the strip to ensure that the strip maintains an accurate transmission route during operation. This strip position tracking mechanism based on the tension roller enables the system to perform high-precision real-time calculation of the defect position on the strip under different production speeds and tension conditions. By calculating the relative distance between the defect mark and the mill entrance, the system can clearly display the remaining distance for each defect on the strip to reach the mill entrance, allowing operators to prepare in advance and take appropriate treatment measures.

[0073] The advantage of this real-time position tracking is that the system can predict the defect location before the strip enters the mill entrance, especially when a serious defect is about to approach the mill entrance, and can trigger the preset shutdown or speed reduction response strategy in advance, thereby protecting the rolls and equipment and avoiding damage caused by defects entering the mill. Through this fixed position reference between the pickling operation room and the mill entrance, the system not only achieves accurate position tracking of defects, but also provides a reliable foundation for intelligent control of the production line. Ultimately, real-time defect position calculation and display make the entire production process more transparent, and operators can grasp the real-time location of defects at any time through the system interface, improving the safety and production efficiency of the production line.

[0074] In some examples, the above-mentioned response strategy is executed for the above-mentioned defect based on the marking position and the mill entrance position on the above-mentioned acid continuous rolling production line, including:

[0075] When the distance between the marked position and the mill entrance position on the above-mentioned acid continuous rolling production line is zero,

[0076] In the case where the above-mentioned defect is of the first defect type, controlling the rolling mill to perform empty coil operation; or,

[0077] In the case where the defect is of the second defect type, the rolling mill is controlled to perform the rolling operation of the strip at a speed greater than or equal to a third preset speed and less than or equal to a fourth preset speed.

[0078] For example, when the system detects that the distance between the defect mark position and the rolling mill entrance position reaches zero, that is, the defect has reached the rolling mill entrance, the system will automatically trigger different control strategies according to the defect type to deal with different defect conditions on the strip surface.

[0079] First, for the first type of defects, such as severe defects such as edge cracks or holes, the system will instruct the mill to perform an empty coil operation, that is, to stop normal rolling of the current strip section. The execution principle of this strategy is based on the protection of the rolls and equipment. Severe defects may damage the roll surface and may even cause the risk of strip breakage during rolling. Therefore, the system effectively avoids the potential risks brought by defects through empty coil operation. The empty coil operation bypasses the strip around the mill, ensuring that severe defects do not enter the mill roller table, thereby avoiding direct impact on the rolls, extending the service life of the equipment, and ensuring the safety and stability of the production line.

[0080] Secondly, for the second type of defects, such as slight surface peeling, slag curling and other defects that will not damage the equipment, the system will adjust the rolling speed to adapt to the defect processing requirements. At this time, the system will reduce the rolling speed of the rolling mill to between the third preset speed and the fourth preset speed, where the third preset speed is 120 meters per minute and the fourth preset speed is 150 meters per minute, passing through the rolling mill area at a lower speed. Reducing the speed not only reduces the friction and impact of the defects on the rollers, but also allows the strip to pass through the defective area more smoothly, allowing the strip to continue normal rolling operations without affecting the equipment life and production efficiency. The selection of this preset speed is based on a comprehensive consideration of the mill load and production rhythm, ensuring that the rolling process of the strip after the speed adjustment is still stable, which not only guarantees the finished product quality of the strip surface, but also avoids equipment wear caused by slight defects. In the embodiment of the present application, the rolling speed is preferably 130 meters per minute.

[0081] This defect-type-based response strategy design enables the system to have more precise automatic control capabilities and effectively minimize the impact of different types of defects. By real-time tracking and accurately calculating the relative distance between the defect mark position and the mill entrance, the system can respond immediately before the defect reaches the mill, ensuring that both shutdown protection for serious defects and speed reduction rolling for minor defects can be automatically and efficiently executed. This differentiated processing strategy not only improves the safety of the production line, but also optimizes the rolling quality of the strip, providing reliable technical support for the efficient and intelligent production of the acid continuous rolling production line.

[0082] In some examples, it also includes:

[0083] Standardize the transmission of hot-rolled coil slag information, add screening conditions to the trimming plan, automatically enlarge and bold the font of defect notes containing "coil slag, warping, inclusions", screen out the steel coils with coil slag notes in advance, mark them, and pay special attention to them during production.

[0084] For example, if there are defects such as slag curling, warping and inclusions on the surface of the strip, the system will automatically enlarge and bold the fonts of these keywords in the defect notes to ensure that operators can immediately notice these potential defect information when viewing the production plan. This design of highlighting information makes the transmission of defect information more intuitive in the production process, avoiding the problem of defects not being discovered in time due to missing or unclear information.

[0085] In addition, in order to ensure accurate control during the production process, the system screens coils with slag or other special defects in advance, and marks these coils significantly based on the defect notes. Through this marking function, the system can classify and process coils that require special attention before production, so that they can be specially managed when entering the trimming process. During the production process, operators can take a more cautious approach to these coils with specific defects based on the system's screening and marking information, ensuring that the defects can be avoided during the trimming operation and reducing potential damage to the equipment and strip quality.

[0086] This information screening and highlighting control strategy has greatly improved the information transmission efficiency of the production line, allowing all key data related to defects to be displayed in a timely and accurate manner, laying the foundation for the precision and intelligence of production operations. At the same time, early screening and marking of steel coils with defects such as coil slag can help production personnel make more efficient predictions and processing during operations, effectively reducing the impact of strip defects on subsequent processes and improving overall production quality and efficiency.
