[0002] Hot rolled strip refers to a plate produced by hot rolling. The billet is processed into a steel coil of specific thickness and width according to user needs. However, due to the temperature difference between the edge and the middle of the billet during the processing, the billet is deformed during the hot rolling process, resulting in edge warping, which affects the use of the strip. In addition, due to the different temperatures and types of the processed billets, different types of billets have uneven thicknesses during the process of being processed into strips, resulting in a large difference between the actual thickness of the hot rolled strip and the target thickness. In addition, due to the different degrees of oxidation on the billet surface, the thickness of the oxide layer is different, and the material and thickness of the billet are different, resulting in the inability of the existing technology to accurately control the heating temperature and the extrusion pressure of the vertical roll, and the inability to remove the oxide layer completely.

[0041] Step S2 further comprises the following steps:

[0042] Step S21: retrieve the material and thickness of the current steel billet to be processed, retrieve the historical heating temperature and the corresponding steel billet thickness in the database according to the material of the current steel billet, and give the influence coefficient α of the steel billet thickness on the heating temperature according to the relationship between the historical heating temperature and the steel billet thickness;

[0043] Step S22: retrieve the ultrasonic detection data, read the ultrasonic dot matrix data, build a three-dimensional model of the steel billet according to the ultrasonic dot matrix data, build a coordinate system, scan and identify the inflection point of the data change in the ultrasonic dot matrix data, mark the corresponding coordinates in the three-dimensional model of the steel billet according to the inflection point of the data change, and calculate the oxide layer thickness of the current steel billet according to the inflection point of the data change. Where, i = 1, 2, 3 ..... n, H represents the average thickness of the oxide layer of the current steel billet, j represents the error hardness coefficient of the average thickness of the oxide layer of the current steel billet, (X 1 , Y1 ), (X 2 , Y 2 ) represent the coordinates of the upper vertex and the lower vertex of the oxide layer of the steel billet in the vertical direction, and the heating temperature required for the current steel billet is calculated according to the formula In the formula, Q represents the heating temperature required for the current steel billet, q represents the lowest heating temperature for the current material steel billet, H represents the average thickness of the oxide layer of the current steel billet, and β represents the influence coefficient of the current oxide layer thickness on the heating temperature of the steel billet. The steel billet model is constructed by ultrasonic detection, the oxide layer thickness of the steel billet is accurately calculated, and the influence of the oxide layer thickness of the steel billet and the thickness of the steel billet on the heating temperature of the steel billet is analyzed. The heating temperature required for the steel billet can be accurately calculated, so that the steel billet reaches the optimal processing temperature, which can make the surface impurities easier to handle, reduce impurity residues, reduce the generation of defective products, and improve the qualified rate and quality of products;

[0044] Step S23: When processing the oxide layer of the steel billet, the roll pressure coefficient κ required for the steel billet of unit thickness h in the database is retrieved according to the material of the steel billet, and the pressure value between the vertical roller dephosphorization device is calculated according to the formula F represents the pressure value between the vertical roller dephosphorization device, H g It represents the thickness of the steel billet, p represents the attenuation coefficient of the oxide layer on the surface of the steel billet to the pressure, and the vertical roller dephosphorization device is started to extrude and dephosphorize the steel billet.

By analyzing the resilience and cooling shrinkage of the strip material, the actual thickness of the strip that needs to be rolled can be accurately calculated, reducing the difference between the actual thickness of the rolled strip and the target thickness, further improving the accuracy of the system.

[0049] In step S4, the speed of each device in processing the strip is retrieved, and the processing speeds between adjacent devices are compared. If the processing speed difference is greater than a threshold value, the operating speed of the faster device is reduced, otherwise the system continues to process the billet, retrieves laser detection data, scans and identifies the edge feature nodes of the strip, connects the edge feature nodes, constructs a contour model of the strip, establishes a coordinate system, measures the length of the strip edge, and calculates the distance between the two end points on one side of the strip by the distance formula between two points, that is, the theoretical length of the edge of one side of the strip. If the difference between the strip edge length measured by the laser detector and the theoretical length is less than a threshold value, the current strip is marked as a rollable strip, otherwise it is marked as an unrollable strip. When the equipment is coiling, if the laser detection device detects that the strip is offset, the guide plate is started to move in the opposite direction of the strip offset to correct the strip coiling, otherwise the system continues to coil. By comparing the edge length of the strip with the theoretical length, it is possible to promptly detect whether the strip is bent, thereby avoiding the strip from offsetting the coil during the coiling process, thereby further improving the quality and pass rate of the product.

The equipment control module also includes a correction module, which is used to correct the strip steel according to the warping and uneven thickness of the steel billet marked by the system; The operating method of the equipment control system comprises the following steps: Step S1: Using the visual module, take visual images of the steel billet to be processed and the steel billet during processing, record and save them in the system, collect the status data of the equipment in the operation process in real time through the sensor module, and enter the comprehensive data of the steel billet into the system through the steel billet information entry module; Step S2: When the strip steel starts to be rolled, the system sends an electrical signal to trigger the surface detection submodule to start, and starts to analyze the thickness of the oxide layer on the surface of the billet and the influence of the billet thickness on the heating temperature and the vertical roll pressure, and processes the billet according to the analysis results; Step S3: During the rolling process, the system starts the surface detection submodule and the thickness detection submodule, starts to analyze whether the surface of the processed strip is flat, whether the thickness of the processed strip is uniform, and adjusts the equipment according to the analysis results; Step S4: Monitor and analyze the running speed of the equipment in the production chain in real time, and adjust the running speed of the equipment according to the analysis results. When the strip is rolled into a coil, the correction module is started, and adjustments are made according to the offset of the coil. The guide plate position is adjusted to align the edges of the coil to complete the strip rolling.

2. An industrial production equipment control system according to claim 1, characterized in that: In the step S4, the strip processing speed of each device is retrieved, and the processing speeds between adjacent devices are compared. If the processing speed difference is greater than a threshold value, the operating speed of the faster device is reduced, otherwise the system continues to process the steel billet, retrieves laser detection data, scans and identifies edge feature nodes of the strip, connects the edge feature nodes, constructs a contour model of the strip, establishes a coordinate system, measures the length of the strip edge, and calculates the distance between the two end points on one side of the strip by a two-point distance formula, that is, the theoretical length of the edge of one side of the strip. If the difference between the strip edge length measured by the laser detector and the theoretical length is less than a threshold value, the current strip is marked as a rollable strip, otherwise it is marked as an unrollable strip. When the equipment is coiling, if the laser detection device detects that the strip is offset, the guide plate is started to move in the opposite direction of the strip offset to correct the strip coiling, otherwise the system continues to coil.
