Description

Technical Field

[0001] This invention relates to double-high-line control technology, and more specifically, to a control method and system for detecting the amount of rolling in a horizontal looper on a double-high-line. Background Technology

[0002] The horizontal loopers in a steel rolling mill are crucial because the control accuracy and reliability of the four horizontal loopers directly affect the speed stability of the finishing mill, as well as the speeds of the pinch rolls and wire spinneret. Furthermore, the quality adjustment of the finished product from the horizontal loopers upstream of the finishing mill is critical, so the horizontal loopers in the high-speed rolling mill also significantly impact the quality of the finished product. During normal rolling, any abnormality or deviation in the looper's workpiece measurement detection will directly lead to drastic speed fluctuations in the finishing mill, pinch rolls, and wire spinneret, resulting in steel buildup. It will also cause dimensional deviations in the finished product, causing serious quality problems. However, current technology lacks an effective solution to these problems. When steel buildup or finished product quality issues occur, the relevant horizontal looper workpiece measurement detection system needs to be replaced and readjusted. This severely impacts normal production, causing a reduction in output and production efficiency. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide a control method and system for detecting the amount of rolling mill rolls in a double-high-speed horizontal looper, which addresses the shortcomings of the existing technology and solves the problem that abnormalities or deviations in the identification of the amount of rolling mill rolls in a horizontal looper affect normal production.

[0004] The present invention discloses a control method for detecting the level looper quantity of horizontal looper rolling mill pieces in a double-high-speed wire rod mill. This method adds a backup horizontal looper rolling mill quantity detection system to the existing system. The existing system collects the operating parameters of the horizontal looper as primary parameters, while the backup system collects these parameters as backup parameters. The primary and backup parameters are compared and analyzed to identify abnormal parameters. Anomaly analysis of these parameters is used to locate and confirm fault points. The priority of each fault point is determined based on its priority level. If the priority exceeds a set target priority, the existing system is switched to the backup system, and the original system is stopped.

[0005] Preferably, the comparative analysis specifically includes:

[0006] Set a deviation threshold range for the operating parameters, perform a difference operation between the main parameter and the backup parameter to obtain a deviation value, and determine whether the deviation value is within the deviation threshold range. If it is, do not mark the main parameter as abnormal; otherwise, mark the main parameter as an abnormal parameter.

[0007] Preferably, the anomaly analysis specifically includes:

[0008] Obtain the parameter type of the abnormal parameter, traverse the database used to store abnormal running parameters according to the parameter type to query the abnormal item corresponding to the parameter type from the database, extract fault information and fault handling information from the abnormal item, and obtain the fault point from the fault information.

[0009] Preferably, if the priority of the fault point exceeds the set target priority, both the fault information and the fault handling information will be displayed.

[0010] Preferably, the priority level is set as follows:

[0011] All existing fault points in the horizontal looper rolling mill measurement detection system are obtained. Based on the actual operating conditions of the horizontal looper rolling mill measurement detection system, the fault points are sorted according to whether they affect the normal operation of the horizontal looper, resulting in a priority sequence of the fault points. Based on the principle of whether they affect the normal operation of the horizontal looper, the target priority is inserted between the priority levels corresponding to the fault points that affect the normal operation of the horizontal looper and the priority levels corresponding to the fault points that do not affect the normal operation of the horizontal looper.

[0012] Preferably, after the horizontal looper rolling quantity detection system collects the operating parameters of the horizontal looper, it performs filtering processing on the operating parameters.

[0013] Preferably, when the original horizontal looper rolling quantity detection system collects the operating parameters of the horizontal looper normally, the standby horizontal looper rolling quantity detection system is only used to collect the operating parameters of the horizontal looper.

[0014] A control system for detecting the rolling quantity of horizontal looper rolling sections in a double-high-speed line includes an original horizontal looper rolling section detection system and a backup horizontal looper rolling section detection system. The original horizontal looper rolling section detection system and the backup horizontal looper rolling section detection system use the control method described above to control the operation of the horizontal looper.

[0015] Beneficial effects

[0016] The advantages of this invention are as follows: A backup horizontal looper rolling quantity detection system is added to the existing horizontal looper rolling quantity detection system on the double-high-speed rolling mill. By comparing and analyzing the operating parameters collected by these two systems, it is possible to determine whether the original system has a fault and whether the backup system needs to be switched to ensure normal equipment operation. This solves the problem of abnormal or deviated rolling quantity identification of the horizontal looper affecting normal production, ensuring smooth rolling production and effectively preventing steel accumulation. Detailed Implementation

[0017] The present invention will be further described below with reference to embodiments, but this does not constitute any limitation on the present invention. Any limited modifications made by any person within the scope of the claims of the present invention are still within the scope of the claims of the present invention.

[0018] This invention discloses a control method for detecting the level looper quantity of rolled pieces in a double-high-speed wire rod mill. This method adds a backup level looper quantity detection system to the existing system. When the existing system detects normal operating parameters of the level looper, it controls the movement of the level looper. The backup system, however, is only used to collect the operating parameters. Specifically, the existing system collects the operating parameters as the primary parameters, while the backup system collects these parameters as backup parameters. To ensure timely detection of the original horizontal looper rolling mill measurement system, the main parameters and backup parameters are compared and analyzed to identify abnormal parameters in the operating parameters. Anomaly analysis of these parameters is used to locate and confirm fault points. The priority of the fault point is determined based on its priority level; if it exceeds the set target priority, the original horizontal looper rolling mill measurement system is switched to the backup system, and the original system is shut down. This ensures smooth production and rolling, effectively preventing steel buildup and improving output, yield, and rolling efficiency. Furthermore, it ensures stable quality of the finished products rolled by the finishing mill, improving overall output and quality.

[0019] In this process, after the two horizontal looper rolling quantity detection systems collect the operating parameters of the horizontal loopers, the operating parameters need to be filtered. Specifically, this can be achieved by using electromagnetic shielded cable transmission, anti-interference processing, and end-matching correction, thereby achieving the goal of lossless transmission of operating parameters.

[0020] The comparative analysis in this embodiment specifically includes: setting a deviation threshold range for the operating parameters, performing a difference calculation between the main parameter and the backup parameter to obtain the deviation value, and determining whether the deviation value is within the deviation threshold range. If it is, the main parameter is not marked as abnormal; otherwise, the main parameter is marked as an abnormal parameter. By comparing the parameter with the threshold, the system can detect abnormal parameters in a timely manner, improving the system's timeliness.

[0021] Furthermore, anomaly analysis specifically includes: obtaining the parameter type of the abnormal parameter; traversing the database used to store abnormal operating parameters according to the parameter type to query the corresponding abnormal item from the database; extracting fault information and fault handling information from the abnormal item; and identifying the fault point from the fault information. By pre-storing abnormal data in the database and using search and traversal methods, the fault point can be quickly identified, and fault handling information can be extracted to facilitate subsequent fault handling. If the priority of the fault point exceeds the set target priority, both the fault information and fault handling information will be displayed, for example, by sending it to the administrator's mobile phone or displaying it on the industrial control computer screen. If the priority of the fault point does not reach the target priority, fault handling will be terminated, and no fault handling information will be displayed.

[0022] In this embodiment, the priority level setting method is as follows: All existing fault points in the horizontal looper rolling mill measurement detection system are acquired. Based on the actual operating conditions of the horizontal looper rolling mill measurement detection system, the fault points are sorted according to whether they affect the normal operation of the horizontal looper, resulting in a priority sequence of fault points. For example, if certain operating parameters are identified as fault parameters and corresponding fault points are identified, but changes in these operating parameters do not affect the normal operation of the horizontal looper, then these operating parameters are considered not to affect the normal operation of the horizontal looper. Based on the principle of whether or not the normal operation of the horizontal looper is affected, a target priority is inserted between the priority levels corresponding to fault points that affect the normal operation of the horizontal looper and those that do not. This priority system effectively distinguishes different types of fault points, thereby avoiding faults that do not affect the normal operation of the horizontal looper and preventing changes in control state during equipment operation from affecting normal equipment operation.

[0023] A control system for detecting the rolling quantity of horizontal loopers in a double-high-speed rolling mill includes an existing horizontal looper rolling quantity detection system and a backup horizontal looper rolling quantity detection system. Both systems utilize the aforementioned control method to control the operation of the horizontal loopers. This ensures smooth and stable rolling production, effectively preventing steel accumulation and improving output, yield, and rolling completion rate. Furthermore, it ensures stable quality of the finished products rolled from the finishing mill, thereby improving overall output and quality.

[0024] The above description is only a preferred embodiment of the present invention. It should be noted that those skilled in the art can make several modifications and improvements without departing from the structure of the present invention, and these will not affect the effectiveness of the implementation of the present invention or the practicality of the patent.
