Abstract
Description
Technical Field
[0001] This invention relates to the field of intelligent manufacturing technology in the metallurgical industry, and specifically designs an anomaly handling method and device suitable for tracking hot-rolled steel pipes one by one. Background Technology
[0002] Traditional steel pipe manufacturers primarily rely on manual methods for tracking the production process, tracing data by furnace number or batch number. However, with advancements in production technology and increasingly stringent quality requirements, current standards mandate sequential marking and tracking of each steel pipe's testing data. This ensures that production process data corresponds to each individual pipe, achieving transparency and precision. The traditional seamless steel pipe manufacturing method of tracking by furnace number or batch no longer meets these requirements.
[0003] Steel pipe production is a discrete and discontinuous processing mode, and the removal and rework of defective products during the production process is inevitable. Traditional steel pipe companies generally use manual on-site recording for tracking. This tracking method is extremely costly in terms of manpower, material resources, and financial resources, and it is inconvenient to accurately track individual steel pipes that are removed from the production line due to production defects. It can also easily lead to chaos in the subsequent production process, hindering later root cause analysis and production process improvement and upgrading.
[0004] Material tracking, piece by piece, is fundamental to achieving precise control, quality traceability, and refined energy management in steel pipe production. Currently, the challenge lies in the complex flow of pipes between various processes, involving frequent loading and unloading, which easily leads to numerous anomalies. Handling these anomalies and ensuring the accuracy of the piece-by-piece tracking logic remains a difficult problem. Summary of the Invention

[0024] The received information on the loading and unloading of steel pipes is synchronized to the corresponding individual tracking queue to correct the tracking queue.
[0025] Optionally, the method further includes:
[0026] During the hot rolling process of steel pipes, an abnormal on-site detection signal is determined when one of the following second preset conditions is detected:
[0027] The second preset scenario includes:
[0028] Before the steel pipe enters the tracking queue for the next process, there is no signal indicating the steel pipe has arrived at the end of the previous process, indicating an abnormal detection signal at the designated single-process entry point; or,
[0029] The number of steel biting signals and steel throwing signals detected at the main equipment of a single process are different.
[0030] This application embodiment also provides an anomaly handling device for hot-rolled steel pipe tracking, wherein the device includes:

[0050] The second preset scenario includes:
[0051] If there is no signal indicating the arrival of a steel pipe at the end of the previous process before the steel pipe enters the tracking queue for the next process, it indicates an anomaly in the detection signal at the entry point of the single process; or...
[0052] The number of steel biting signals and steel throwing signals detected at the main equipment of a single process are different.
[0053] The above technical solution has at least the following advantages compared with the existing technology:
[0054] The anomaly handling scheme for hot-rolled steel pipe tracking provided in this application embodiment determines whether the operation of the single-process equipment is abnormal by judging whether the steel pipe meets the first preset condition when it enters the next process tracking queue from the current process tracking queue.

Obviously, the described embodiments are only some, not all, of the embodiments of the present invention.

[0061] It should be noted that the terms "up", "down", "left", "right", "front", and "back" used in this invention are only used to indicate relative positional relationships. When the absolute position of the object being described changes, the relative positional relationship may also change accordingly.
[0062] This application provides an anomaly handling method for hot-rolled steel pipes, tracking each pipe individually, such as... Figure 1 As shown, the method includes:
[0063] Step S101: Determine whether the operation of the single-process equipment is abnormal by judging whether the steel pipe meets the first preset condition when it enters the next process tracking queue from the current process tracking queue.
[0064] The first preset condition includes: no material signal at the end detection device of the previous process, no material signal at the detection device before the end detection device of the previous process, and a material signal detected at the entrance of the next process.
[0065] Common anomalies during hot rolling of steel pipes include, but are not limited to: malfunctions of main equipment in a single process, abnormal stacking of multiple steel pipes in a single process, temporary loading and unloading on the production line, and abnormal on-site detection signals. The system has corresponding logical processing mechanisms for each anomaly. This embodiment uses the detection and processing of malfunctions of main equipment and abnormal stacking of multiple steel pipes in a single process during hot rolling of steel pipes as examples.
[0066] Single-process main equipment malfunction refers to a situation in which equipment fails and cannot work normally due to unexpected events or other unpredictable factors during the production process.
[0067] A preferred method for handling tracking anomalies caused by malfunctions in a single-process main equipment is as follows:
[0068] During the hot rolling process of steel pipe, it is determined that the steel pipe will enter the next process tracking queue from the current process tracking queue. Formula (1) must be satisfied. If it is satisfied, it is determined that a single process main equipment malfunction has occurred.
[0069] P∨Q(1)
[0070] Where P means "the detection device at the end of the previous process has a material signal", and Q means "another detection device before the detection device described in P has a material signal".
[0071] S102: Determine whether there is an abnormal stacking of multiple steel pipes in a single process by using the number of steel pipes detected by the detection signal at the entry point of a single process and the number of steel pipes detected by the preset detection signal at the single process.
[0072] The presence of abnormal stacking of multiple steel pipes in a single process refers to the possibility of misjudging the stacking of two or more steel pipes when they are stacked one after the other in a certain process. This can lead to misidentification of the stacking as a single pipe entering the next process, causing confusion in the tracking logic.
[0073] A feasible method for determining whether an abnormal stacking of multiple steel pipes exists at a single process step can be as follows: if the number of steel pipes detected by the detection signal at the entrance of the single process step is different from the number of steel pipes detected by the preset detection signal at the single process step, it is determined that an abnormal stacking of multiple steel pipes exists at the single process step. Conversely, if the number of steel pipes is the same, it is determined that no abnormal stacking of multiple steel pipes exists at the single process step.
[0074] In one alternative implementation, the logic can be reversed using the accurate detection signal of the next process to correct the tracking anomaly caused by the stacking of multiple steel pipes into the process. If formula (2) is satisfied, it is determined that an anomaly of multiple steel pipes stacking before and after a single process has occurred.
[0075] N1 <N2 (2)
[0076] Where N1 represents the number of steel pipes detected by the detection signal at the entrance of the next process, and N2 represents the number of steel pipes detected by the accurate detection signal in the next process. The accurate detection signal is the preset detection signal, which is assumed to be reliable in this system.
[0077] After determining that there is an abnormal stacking of multiple steel pipes in a single process at a single process location, the following operations can also be performed in this embodiment of the application:
[0078] First, based on the time when each steel pipe is detected at the preset detection signal at the single process, the exact number of each steel pipe entering the single process and the time are calculated; second, based on the calculated exact number of each steel pipe and the time, the abnormal stacking of multiple steel pipes in a single process is tracked and corrected.
[0079] Steps S101 and S102 are detection methods for two different abnormal situations. In actual implementation, there is no requirement for the order of execution of steps S101 and S102.
[0080] In addition to detecting the two abnormal situations mentioned above, this embodiment of the application can also temporarily load and unload materials on the production line when one of the following first preset situations is detected during the hot rolling process of steel pipes;
[0081] The first preset scenario includes:
[0082] If a steel pipe fails to be processed in a certain step, it will be reprocessed off the production line.
[0083] Steel pipes with special process requirements or those that need to be reprocessed are put into the corresponding process on the production line.
[0084] A feasible way to temporarily load and unload materials on the production line is as follows:
[0085] First, the loading and unloading signals and material location information are obtained through an intelligent analysis system;
[0086] The intelligent analysis system provides more accurate information on loading and unloading signals and material location.
[0087] Secondly, display the loading and unloading prompt information bar;
[0088] Next, it receives the steel pipe information for loading and unloading entered by the user;
[0089] Finally, the received information on the loading and unloading of steel pipes is synchronized to the corresponding individual tracking queues to correct the tracking queues.
[0090] When performing the detection in step S102, it is necessary to detect the detection signal at the entry point of a single process. To ensure the accuracy and reliability of the detection results, it is necessary to first ensure the reliability of the detection signal at the entry point of the single process. The preferred implementation provided in this embodiment can determine that the on-site detection signal is abnormal when one of the following second preset conditions is detected during the hot rolling process of the steel pipe. The on-site detection signals include the detection signal at the entry point of the single process, the detection signal at the single-process injection equipment, and the detection signal for operations such as piercing or rolling of the steel pipe. This detection method can identify abnormal detection signals detected at the entry point of the single process.
[0091] The second preset scenario includes:
[0092] Scenario 1: Before the steel pipe enters the tracking queue for the next process, there is no signal indicating that the steel pipe has arrived at the end of the previous process, indicating an abnormality in the detection signal at the entry point of the single process; or,
[0093] Scenario 2: The bite signal and throw signal of the main equipment in a single process are not continuously detected afterward; or,
[0094] Scenario 3: The number of steel biting signals and steel throwing signals detected at the main equipment of a single process are different.
[0095] Scenario 2 is used to ensure that the steel pipe has completed operations such as piercing or rolling, and the rolling or piercing time can be calculated based on the bite and throw signals in Scenario 3.
[0096] The anomaly handling method for hot-rolled steel pipe tracking provided in this application determines whether the operation of the single-process equipment is abnormal by judging whether the steel pipe meets the first preset condition when it enters the next process tracking queue from the current process tracking queue. By using the number of steel pipes detected by the detection signal at the single process entrance and the number of steel pipes detected by the preset detection signal at the single process, it is determined whether there is an abnormal stacking of multiple steel pipes in a single process. This method can ensure the timeliness and accuracy of tracking steel pipes one by one during the hot-rolled steel pipe production process, so as to achieve precise control, quality traceability and refined energy management of steel pipe production.
[0097] This application also provides an anomaly handling method for hot-rolled steel pipes, tracking each pipe individually, such as... Figure 2 As shown, the anomaly handling method for hot-rolled steel pipe tracking provided in this application includes the following four anomaly logic processing methods:
[0098] Abnormal Situation S1: Logical processing under abnormal conditions of main equipment in a single process;
[0099] In abnormal situation S1, the main equipment malfunction in a single process mainly refers to the situation in which the equipment fails and cannot work normally due to unexpected time or other unpredictable factors during the production process.
[0100] The traverse trolley in the piercing zone is used to clamp the steel pipes after piercing and place them at the front of the rolling mill. Due to its frequent movements, the traverse trolley is prone to malfunctions. When a traverse trolley malfunctions, its bite and throw signals become chaotic, leading to abnormal tracking logic. In actual production, to ensure uninterrupted production, the traverse trolley's functions are temporarily performed by an overhead crane during maintenance.
[0101] The following are the methods for handling tracking anomalies in the tube rolling mill area caused by abnormal operation of the transverse trolley:
[0102] To determine whether a steel pipe enters the rolling zone tracking queue from the piercing zone tracking queue, formula (1) must be satisfied:
[0103] P∨Q(1)
[0104] Where P means "there was a material signal at the traverse trolley in the previous time period", and Q means "there was a material signal at the perforator backstage in the previous time period".
[0105] When the rolling mill detects a bite signal and begins rolling, the system first checks for a material signal at the traverse trolley, and then checks for a material signal at the piercing mill's back end. If a material signal is detected at the traverse trolley, it is determined that the traverse trolley has picked up the material from the piercing mill's back end and transferred it to the rolling mill for rolling. If no material signal is detected, it is determined that the overhead crane has picked up the material from the piercing mill's back end and transferred it to the rolling mill. In the abnormal situation S1 described in this invention, if the traverse trolley is replaced with another main process equipment, this method still applies.
[0106] Abnormal Situation S2: Logic handling for abnormal stacking of multiple steel pipes in a single process;
[0107] In abnormal situation S2, the abnormal stacking of multiple steel pipes in a single process specifically refers to the stacking of multiple steel pipes. When entering the next process, the stacking of steel pipes is prone to misjudgment, which will cause the tracking logic to be confused and result in inaccurate tracking of the number of steel pipes.
[0108] The tracking anomaly caused by multiple steel pipes stacked together in the process is corrected by using a single-process accurate detection signal for logical reverse deduction. If formula (2) is satisfied, a tracking anomaly is determined to have occurred:
[0109] N1 <N2 (2)
[0110] Wherein, N1 represents "the number of steel pipes detected by the detection signal at the entrance of the next process", and N2 represents "the number of steel pipes detected by the accurate detection signal in the next process".
[0111] Based on the time when each steel pipe is detected in N2, the logic is used to deduce the exact number of steel pipes entering the process and the time, and then the tracking logic is corrected.
[0112] When two or more steel pipes are stacked and enter the reducing mill, the reducing mill will only reduce the diameter of one pipe at a time, removing the excess pipe. Based on the detection signal at the reducing mill's inlet, it's easy to mistakenly believe that only one pipe has entered, causing tracking logic errors. Furthermore, because some steel pipes with special requirements undergo descaling during the reducing process, additional sensors cannot be added at this point.
[0113] To address the above issues, a signal-back-calculation method based on the cooling bed signal is used to correct tracking anomalies. Steel pipes enter the cooling bed via a fork. Since the fork signal is stable and only one pipe is transferred at a time, it serves as an accurate detection signal, ensuring the accurate number of pipes entering the cooling bed. Therefore, if the number of pipes in the cooling bed tracking queue is greater than the number in the reducing mill tracking queue, it is determined that multiple pipes are stacked and entering the reducing mill. Combining the entry time of each pipe into the cooling bed and the reducing mill's operating time, logical deduction is used to accurately determine the number of pipes entering the reducing mill and the corresponding time, thus correcting the tracking logic.
[0114] Abnormal situation S3: Logic handling for temporary loading and unloading on the production line;
[0115] The abnormal situation S3 involves temporary loading and unloading logic handling on the production line, mainly including two situations:
[0116] Scenario 1: The steel pipe fails to be processed in a certain process and is taken off the production line for reprocessing.
[0117] Scenario 2: Steel pipes with special process requirements or steel pipes that need to be reprocessed are put into the corresponding process on the production line.
[0118] The loading and unloading information involved in the above two situations does not exist in the current production plan. The logic for temporary loading and unloading on the production line includes the following steps:
[0119] Sub-step one: Obtain loading / unloading signals and material location information using the AI analysis system. Based on the crane coordinates and crane movement, the system determines that a temporary loading / unloading situation has occurred during the current production process.
[0120] Step 2: A pop-up message box for loading and unloading materials appears on the PC, where the operator enters the information for the steel pipes being loaded and unloaded.
[0121] Step 3: The system synchronizes the entered steel pipe information to the corresponding pipe-by-pipe tracking queue and corrects the tracking logic.
[0122] Abnormal Situation S4: Logic processing under abnormal on-site detection signals.
[0123] The production site environment is complex, and the field equipment and sensors operate for extended periods, making them highly susceptible to malfunction. Abnormal situation S4, specifically the abnormal detection signal at the production site, refers to an anomaly where the L1 automation system mis-triggers or loses signals when acquiring field signals.
[0124] For abnormal situation S4, the logical processing steps for abnormal field detection signals are as follows:
[0125] In the first sub-step, before the steel pipe enters the next process tracking queue, it is necessary to ensure that there is a steel pipe arrival signal at the end of the previous process. This can avoid tracking chaos caused by false signal triggering on site.
[0126] Sub-step two: After continuously detecting the steel biting and steel throwing signals of a certain single-process main equipment, it is determined that the steel pipe has completed the single process.
[0127] Step 3: Interlock the position of the steel pipe by combining the AI tracking system signal with the on-site logic signal to ensure the accuracy of the steel pipe position.
[0128] It should be noted that the above only describes the system's handling mechanisms for the four abnormal situations mentioned above. In actual implementation, there is no specific order in which the four abnormal situations are handled.
[0129] The abnormal logic processing mechanism for hot-rolled steel pipe tracking provided in this application establishes a total tracking queue and tracking sub-queues for each region. Combined with field signals, it processes abnormal logic during the tracking process according to the first-in-first-out logic of the queue, maintains the elements in the queue, and ensures the accuracy of hot-rolled steel pipe tracking.
[0130] This invention also provides an anomaly handling device for hot-rolled steel pipe tracking, wherein the structural block diagram of the device is as follows: Figure 2 As shown, the anomaly handling device 20 for hot-rolled steel pipe tracking includes the following functional modules:
[0131] The first determination module 201 is used to determine whether the operation of the single-process equipment is abnormal by determining whether the steel pipe meets the first preset condition when it enters the next process tracking queue from the current process tracking queue. The first preset condition includes: no material signal at the end detection device of the previous process, no material signal at the detection device before the end detection device of the previous process, and a material signal detected at the entrance of the next process.
[0132] The second determination module 202 is used to determine whether there is an abnormal stacking of multiple steel pipes in a single process at the single process based on the number of steel pipes detected by the detection signal at the single process entry point and the number of steel pipes detected by the preset detection signal at the single process.

[0153] The anomaly handling device for hot-rolled steel pipe tracking provided in this application establishes a total tracking queue and tracking sub-queues for each region. Combined with on-site signals, it processes the anomaly logic during the tracking process according to the first-in-first-out logic of the queue, maintains the elements in the queue, and ensures the accuracy of hot-rolled steel pipe tracking.
