However, in the prior art, multiple sets of guide devices often cannot be managed as a whole according to a unified standard, resulting in large differences in centering accuracy and consistency among the devices.

[0040] Please refer to Figure 1 , which is a schematic flow chart of a measurement method for aligning a guard device provided by an embodiment of this application, and specifically may include:

[0041] S110. Obtain the initial center line of the rolling mill housing;

[0042] Exemplarily, in order to accurately obtain the initial center line of the rolling mill housing, a high-precision laser tracking measuring instrument is used to comprehensively measure the housings on both sides of the rolling mill, and the three-dimensional space coordinate data of each housing on both sides of the rolling mill are obtained to ensure the high precision and reliability of the data. After obtaining the spatial coordinate data of the housings on both sides, the center position of each housing is accurately calculated to obtain a set of preset center point data. These center point data reflect the actual distribution of the rolling mill housing in space and provide a basis for the subsequent fitting of the initial center line. Based on the calculated center point data, the initial center line is fitted. This initial center line serves as the reference line for the overall operation of the rolling mill and accurately reflects the geometric center distribution of the rolling mill housing.

[0043] S120. Based on the initial center line, simulate the finishing area to obtain a simulated center line;

[0044] Exemplarily, in order to accurately simulate the finish rolling area based on the initial centerline, the initial centerline needs to be extended along the length direction of the finish rolling area first. This extension process ensures that the initial centerline can cover the rolling range of the entire finish rolling area, providing a comprehensive reference line. When extending, the specific length of the finish rolling area and the equipment distribution should be considered to ensure that the ductility of the simulated centerline matches the actual production environment. After extending the initial centerline, it is necessary to optimize and adjust the extended centerline according to the actual layout and geometric features of each equipment in the finish rolling area. Finally, the simulated centerline generated through the above steps not only covers the entire finish rolling area but also accurately reflects the actual distribution and geometric characteristics of the equipment in the area.

[0045] S130. Based on the simulated centerline, determine the offset reference line to optimize the centering measurement process of the guide equipment in the finish rolling area.

[0046] Exemplarily, after generating the simulated centerline, in order to further optimize the centering measurement process of the guide equipment in the finish rolling area, it is necessary to determine the offset reference line based on this simulated centerline. The determination of the offset reference line is achieved by setting several offset measurement points, and the positions of these measurement points usually maintain a certain preset distance from the simulated centerline. The function of the offset reference line is to provide a precise centering standard for the guide equipment in the finish rolling area, thereby ensuring the centering accuracy during the installation and operation of the equipment and avoiding production problems caused by inaccurate centering.

[0047] In some instances, the specific steps for obtaining the initial centerline of the rolling mill housing include:

[0048] Based on a laser tracking measuring instrument, measure the two sides of the rolling mill housing to obtain the spatial coordinate data of the two sides of the housing;

[0049] Based on the spatial coordinate data, calculate the center positions of the two sides of the rolling mill housing to obtain the center points with preset values;

[0050] Based on the center points, fit the initial centerline, including:

[0051] Use the weighted least squares method to fit the center points to determine the initial noisy centerline, where the weight parameter is adjusted according to the thermal expansion and mechanical deformation during the operation of the rolling mill;

[0052] Smooth the fitted initial noisy centerline to obtain the initial centerline to eliminate the measurement noise.

[0053] Exemplarily, in order to accurately obtain the initial center line of the rolling mill housing, the present application uses a high-precision laser tracking measuring instrument to comprehensively measure the rolling mill housings on both sides of the rolling mill. During the specific operation process, first, the laser tracking measuring instrument is installed at a predetermined measurement position to ensure that the line of sight between the measuring instrument and the rolling mill housing is unobstructed, so as to obtain stable and accurate measurement data. Through the measuring instrument, the three-dimensional space coordinates of each rolling mill housing on both sides of the rolling mill are collected to ensure the high precision and reliability of the data. These space coordinate data reflect the actual geometric position of the rolling mill housing under the operating state, providing basic data support for the subsequent center line calculation.

[0054] After obtaining the space coordinate data of the rolling mill housings on both sides, a special calculation method is used to accurately calculate the center position of each rolling mill housing. The specific steps include averaging the coordinate data of each pair of symmetric rolling mill housings to determine its symmetric center point and obtaining the center point positions with preset values. By summarizing and statistically analyzing the center point position data of all rolling mill housings, a set of center point sets representing the overall geometric distribution of the rolling mill is formed. Subsequently, based on these center point position data, the weighted least squares method is used to perform linear fitting to determine the initial noisy center line. During the fitting process, the weight parameter is statically adjusted according to the thermal expansion and mechanical deformation during the operation of the rolling mill to compensate for the possible geometric deformation of the equipment during operation, ensuring the accuracy and robustness of the fitting result.

[0055] Finally, the initial noisy center line obtained by fitting is smoothed to eliminate the noise and errors that may be introduced during the measurement process, and the final initial center line is obtained. The smoothing process uses advanced signal filtering technology to ensure the continuity and stability of the center line. This initial center line serves as the reference line for the overall operation of the rolling mill, accurately reflecting the geometric center distribution of the rolling mill housing, and providing high-precision basic data for the subsequent generation of the simulated center line and the determination of the offset reference line. Through this precise method for obtaining the initial center line, the efficiency and accuracy of the centering measurement of the guide device are ensured, and the production stability and product quality of the entire finishing rolling area are improved.

[0056] It should be noted that in the embodiments of the present application, the preset value is 7, corresponding to the rolling mill housings 7 in the finishing rolling area, labeled as F1 to F7.

[0057] In some instances, based on the initial center line, the finishing rolling area is simulated to obtain a simulated center line, including:

[0058] The initial center line is extended along the length direction of the finishing rolling area to cover the rolling range of the entire finishing rolling area;

[0059] According to the actual layout and geometric characteristics of the equipment in the finishing rolling area, the extended center line is optimized to generate a simulated center line covering the entire finishing rolling area.

[0060] Exemplarily, after obtaining the initial centerline of the rolling mill housing, in order to fully cover the rolling range of the entire finish rolling area, the present application first extends the initial centerline in the length direction of the finish rolling area. In specific operations, using the measurement data and the equipment layout drawing, the initial centerline is extended towards the starting end and the ending end of the finish rolling area to ensure that the extended centerline covers all the positions of the guiding devices involved in the entire rolling process. This extension process needs to consider the actual length of the finish rolling area and its production requirements to ensure the integrity and practicality of the simulated centerline.

[0061] After extending the initial centerline, it is necessary to optimize and adjust the extended centerline according to the actual layout and geometric features of each device in the finish rolling area. Specifically, first analyze the spatial distribution and mutual relationship of each guiding device (including guiding devices numbered from 1 to 6) in the finish rolling area, and identify the symmetry and arrangement rules between the devices. Then, apply a geometric correction algorithm to finely adjust the extended centerline to adapt to the deviation of the device installation position and local geometric changes. For example, if the center position of some guiding devices is shifted due to equipment installation errors or thermal expansion, then by adjusting the position and direction of the centerline, it can more accurately reflect the actual device distribution state. The optimization process also needs to consider the dynamic factors during equipment operation, such as the influence of mechanical deformation and temperature changes on the device position, to ensure the stability and accuracy of the simulated centerline under various operating conditions.

[0062] Finally, through the above extension and optimization steps, a simulated centerline covering the entire finish rolling area is generated. This simulated centerline not only comprehensively covers the positions of all guiding devices, but also accurately reflects the geometric features and operating states of the devices in the finish rolling area. The simulated centerline serves as a reference benchmark for the centering measurement of subsequent guiding devices, which can significantly improve the overall accuracy and consistency of the centering measurement. Through this method, the centering accuracy of the guiding devices in the finish rolling area during the rolling process is ensured, the stability of the rolling process is optimized, and the consistency of product quality and production efficiency are improved.

[0063] In some instances, based on the simulated centerline, a bias reference line is determined to optimize the centering measurement process of the guiding devices in the finish rolling area, including:

[0064] Based on the simulated centerline, a preset number of bias measurement points are set;

[0065] Based on the bias measurement points, a bias reference line is generated.

[0066] Exemplarily, after the generation of the simulated center line is completed, in order to further optimize the centering measurement process of the guide equipment in the finishing area, a preset number of offset measurement points are set according to the simulated center line. In this embodiment, the preset number is 3, which are respectively identified as the first offset measurement point 9, the second offset measurement point 10, and the third offset measurement point 11. The first offset measurement point is located at the position of the entrance guide plate 1 of the coiler, and is used to provide a reference point at the starting end of the finishing area; the second offset measurement point is set at the position between the vertical roll 5 at the entrance of the finishing mill and the F1 guide, as a middle reference point; the third offset measurement point is located behind the F7 mill housing 7, and provides a reference point for the end of the finishing area. This arrangement ensures that the three measurement points can cover the entire finishing area, thereby realizing the accurate generation of the offset reference line. These offset measurement points are located on the operator side of the rolling mill and are parallel to the simulated center line, ensuring consistency and reliability during the measurement process.

[0067] Connect any two points with a laser tracking measuring instrument to generate an offset reference line 12 that is parallel to the simulated center line and at a preset distance. This offset reference line serves as a reference benchmark for the centering measurement of the guide equipment in the finishing area, and can quickly and accurately verify the centering accuracy of the guide equipment in the finishing area. By using the offset reference line, the cumbersome steps of re-obtaining the simulated center line every time a measurement is taken are avoided, greatly improving the measurement efficiency and consistency.

[0068] In addition, the setting of the offset reference line not only simplifies the centering measurement process, but also reduces the measurement errors caused by environmental changes or equipment operation by providing a stable measurement benchmark. The use of the offset reference line ensures the consistency of the centering accuracy of the guide equipment throughout the finishing area, and improves the stability of the rolling process and the product quality.

[0069] In some instances, the offset reference line is at a preset distance from the simulated center line, and the offset reference line is set on the operator side of the rolling mill and is parallel to the simulated center line.

[0070] Exemplarily, during the process of determining the offset reference line based on the simulated center line, it is necessary to keep a preset distance between the offset reference line and the simulated center line. In this embodiment, the preset distance between the offset reference line and the simulated center line is 10 to 15 meters, preferably 12 meters; this distance is determined according to the equipment layout and actual production requirements in the finishing area to ensure that the guide equipment has sufficient operating space and a stable centering benchmark during the rolling process. The selection of the preset distance takes into account the working environment on the operator side of the rolling mill, the equipment spacing, and the effective measurement range of the measuring instrument to ensure the operability and measurement accuracy of the offset reference line in practical applications.

[0071] In addition, the offset reference line is set on the operating side of the rolling mill and is parallel to the simulated center line. This layout helps to simplify the centering measurement process and improve the efficiency and consistency of the measurement. By setting the offset reference line on the operating side, interference caused by equipment operation during the measurement process can be avoided, and at the same time, it ensures that the measuring instrument can stably and accurately capture the position changes of the guide equipment. The parallel offset reference line not only provides a reliable centering benchmark but also maintains a consistent measurement standard under different operating conditions, reducing measurement errors caused by environmental changes or equipment movement.

[0072] Through the above setting method, the offset reference line forms a stable and accurate centering benchmark in the finishing rolling area, greatly optimizing the centering measurement process of the guide equipment. The design of the preset distance and parallel layout not only improves the convenience and accuracy of the measurement but also ensures the centering accuracy and consistency of the guide equipment during the rolling process.

[0073] In some instances, it also includes:

[0074] The offset measurement point is a stainless steel reference point and is fixed using non-shrinking epoxy resin to form a permanent reference position.

[0075] Exemplarily, three offset measurement points 9, 10, and 11 are selected from high-strength and non-corrosive stainless steel materials to ensure excellent durability and stability in various working environments. The stainless steel reference point, due to its excellent mechanical properties and corrosion resistance characteristics, can maintain its geometric shape and position unchanged during long-term use, providing a reliable measurement benchmark.

[0076] To firmly fix the stainless steel reference point on the installation base of the equipment, non-shrinking epoxy resin is used as the bonding material. The non-shrinking epoxy resin hardly undergoes volume change during the curing process, ensuring that the precise position of the reference point after fixation is not affected by material shrinkage. This fixing method not only improves the stability of the reference position but also effectively prevents position offset caused by temperature changes or mechanical vibrations, thus ensuring the long-term accuracy and consistency of the measurement benchmark.

[0077] By adopting the stainless steel reference point and non-shrinking epoxy resin fixing technology, the formed permanent reference positions play a key role in the centering measurement process of the guide equipment in the finishing rolling area. These permanent reference positions provide a stable and reliable benchmark for subsequent centering measurements, significantly reducing measurement errors caused by the movement or deformation of the reference positions. At the same time, the high durability and stability of the permanent reference positions reduce the maintenance frequency and cost, improve the efficiency and accuracy of the overall measurement system, and further ensure the stability of the production process in the finishing rolling area and the high consistency of product quality.

[0078] Schematic diagram of the guide equipment layout in the finishing rolling area is asFigure 2 As shown, the arrangement of the guiding equipment in the finishing rolling area includes multiple key structures, and its main function is to ensure the accurate centering and stable operation of the rolled piece during the rolling process. The simulated centerline 8 runs through the entire finishing rolling area and serves as the reference line for equipment centering. It extends to cover the entire finishing rolling area from the entrance of the coiler to the entrance of the F2 - F7 mills. The main guiding equipment arranged along the simulated centerline includes the coiler entrance guide plate 1, the coiler No. 1 guide plate 2, the coiler No. 2 guide plate 3, the flying shear entrance guide plate 4, the vertical rolls at the entrance of the finishing mill 5, and the entrance guiding equipment for F2 - F7 6. The reasonable layout of these guiding equipment ensures the smooth transition and accurate biting of the rolled piece throughout the finishing rolling area.

[0079] To further improve the efficiency and accuracy of centering measurement, the first offset measurement point 9, the second offset measurement point 10, and the third offset measurement point 11 are set on the operating side of the simulated centerline. These offset measurement points are fixed in place through stainless - steel reference points, are 12 meters away from the simulated centerline, and are connected by a laser tracking measuring instrument to generate an offset reference line 12. The offset reference line is parallel to the simulated centerline and is the main reference benchmark for subsequent centering measurement and verification of the guiding equipment. This arrangement method not only greatly simplifies the measurement process but also effectively reduces the measurement errors caused by equipment position adjustment or changes in the operating environment.

[0080] Through the above - mentioned structural arrangement, the guiding equipment in the finishing rolling area forms a complete centering measurement system based on the simulated centerline and the offset reference line. This system effectively improves the centering accuracy of the equipment, ensures the stability of the rolling process and the consistency of product quality, and at the same time reduces the equipment maintenance cost and production risk.

[0081] The flying shear guiding rolls and the finishing mill guiding rolls are as Figure 3 and Figure 4 shown.

[0082] In some cases, to solve the problem of excessive wear of the guiding plates due to sliding friction when they frequently contact the strip steel, the guiding equipment at key positions is optimized. For the flying shear entrance guide plate 4, a single flying shear guiding roll 13 is added. The main function of this guiding roll is to convert the original sliding friction mode into rolling friction. Through the rotation of the guiding roll, the friction coefficient between the guide plate and the strip steel is effectively reduced, thereby slowing down the wear speed of the guide plate, extending the service life of the equipment, and at the same time enhancing the stability of the centering accuracy.

[0083] For the entry guide 6 of the finishing mill, a finishing mill guide roll 14 with a double-guide-roll structure is designed, which further enhances the friction optimization ability of the equipment. The double-guide-roll structure can evenly distribute the contact pressure of the strip steel, reduce local wear caused by excessive single-point pressure, and improve the running stability of the strip steel when passing through the guide equipment. This structural design is particularly suitable for the working environment at the entrance of the finishing mill because the equipment at this position needs to bear a large load and frequent strip steel passing operations. The coordinated action of the double guide rolls not only reduces the maintenance frequency of the equipment but also ensures the long-term maintenance of the centering accuracy.

[0084] Through the optimization of the above guide roll structure, the flying shear entry guide plate 4 and the finishing mill entry guide 6 have been significantly improved in terms of function and durability. This design solves the technical bottleneck of excessive wear of the guide plate, reduces production problems caused by the decline of equipment accuracy, and further improves the efficiency of the rolling process and the product quality.
