Description

Technical Field

[0001] This invention relates to the field of hot rolling production technology, and in particular to a method, apparatus, electronic device, and storage medium for calibrating the center line of a vertical roll. Background Technology

[0002] A vertical roll mill is a mechanical device used in the steel rolling process from raw materials to finished products. It generally consists of several units including the rolling mill and a series of auxiliary equipment. The function of the vertical roll mill is to reduce the width of the slab to ensure that the width of the finished product meets the standard. Since the width reduction of the vertical roll is achieved by the simultaneous contraction of the drive side and the operating side, the position of the center line of the vertical roll determines the length of contraction of the hydraulic cylinders on both sides.

[0003] In actual production, the large impact loads on the archway during production can cause distortion of the archway window dimensions, leading to strip deviation. Simultaneously, the slab rolling process can result in width loss at both ends, causing strip deviation and increasing the risk of steel accumulation during subsequent rolling. Therefore, to ensure good roughing roll shape, the vertical roll centerline position may need to be adjusted in real time during production. Existing vertical roll centerline calibration methods have the following problems: each manual measurement requires multiple entries into a confined space, resulting in a harsh environment, large measurement errors, and increased operator risk due to the need to continuously oscillate the hydraulic cylinders on both sides. Furthermore, rolling must be stopped every time the vertical roll centerline is calibrated, impacting production efficiency. Summary of the Invention

[0004] In view of the shortcomings of the prior art described above, the purpose of this invention is to provide a method, device, electronic device and storage medium for calibrating the center line of a vertical roll, in order to solve the problems of difficult operation, large measurement error, safety hazards and the need to stop rolling for calibration, which affects production efficiency in the prior art.

[0005] To achieve the above and other related objectives, the present invention provides a method for calibrating the centerline of a vertical roller, comprising:

[0006] Calibration blocks are installed at the ends of the roller conveyor baffles on both sides of the vertical roller mill frame beam;

[0007] Place the measuring ruler on the calibration block and make it in contact with the calibration block;

[0008] Move the vertical roller on the same side as the calibration block so that the end face of the vertical roller bearing seat comes into contact with the measuring ruler;

[0009] The center of the vertical roller opening is marked as the center line of the vertical roller;

[0010] The center line of the vertical roller is adjusted according to the preset strip deviation value.

[0011] Optionally, the vertical roller bearing housing includes a drive side and an operating side, and the roller conveyor baffle is respectively disposed below the drive side and the operating side.

The opening degree of the operating side is adjusted to

[0013] Optionally, the vertical roller bearing housing is provided with a hydraulic cylinder for driving and a balance cylinder for stabilization, and the opening degree of the transmission side and the operating side is adjusted by the balance cylinder.

[0014] Optionally, the center line between the calibration blocks coincides with the center line of the vertical roller.

[0015] Based on the same inventive concept, the present invention also provides a centerline calibration device, the device comprising:

[0016] The mounting module is used to set calibration blocks at the ends of the roller conveyor baffles on both sides of the vertical roller frame beam;

[0017] The detection module is used to place the measuring ruler on the calibration block and make it in contact with the calibration block;

[0018] The moving module is used to move the vertical roller on the same side as the calibration block so that the end face of the vertical roller bearing seat is in close contact with the measuring ruler.

[0019] The calibration module is used to calibrate the center point of the vertical roll opening as the center line of the vertical roll;

[0020] The adjustment module is used to adjust the center line of the vertical roll according to the preset strip deviation value.

[0025] As described above, the vertical roller centerline calibration method, apparatus, electronic device, and storage medium of the present invention have at least the following beneficial effects:

[0026] By setting calibration blocks at the ends of the roller table baffles on both sides of the vertical roll mill frame beam, measurements can be taken without the operator entering the mill. The measuring ruler is placed on the calibration block and brought into contact with it. The vertical roll on the same side as the calibration block is moved so that the end face of the vertical roll bearing seat is in contact with the measuring ruler, and the calibration block is made parallel to the vertical roll bearing seat, ensuring the accuracy of the calibration results.

[0037] In the following description, numerous details are explored to provide a more thorough explanation of embodiments of the invention. However, it will be apparent to those skilled in the art that embodiments of the invention may be practiced without these specific details. In other embodiments, well-known structures and devices are shown in block diagram form rather than in detail to avoid obscuring embodiments of the invention.

[0038] In one exemplary embodiment, this application provides an exemplary method for calibrating the centerline of a vertical roller. Please refer to [link to relevant documentation]. Figure 1 , Figure 1 This is a flowchart illustrating an exemplary embodiment of a vertical roller centerline calibration method, which includes at least steps S110 to S150, detailed below:

[0039] Step S110: Set calibration blocks at the ends of the roller conveyor baffles on both sides of the vertical roller mill frame beam;

[0040] Step S120: Place the measuring ruler on the calibration block and make it in contact with the calibration block;

[0041] Step S130: Move the vertical roller on the same side as the calibration block so that the end face of the vertical roller bearing seat is in contact with the measuring ruler.

[0042] Step S140: Mark the center of the vertical roller opening as the vertical roller centerline;

[0043] Step S150: Adjust the center line of the vertical roller according to the preset strip deviation value.

[0044] Steps S110 to S150 are described in detail below:

[0045] In step S110, calibration blocks are set at the ends of the roller conveyor baffles on both sides of the vertical roller frame beam.

[0046] It should be noted that in the existing technology, the adjustment and calibration of the vertical roll centerline requires operators to enter the rolling mill to measure the positions of the hydraulic cylinders on both sides. The interior space of the rolling mill is narrow and the environment is harsh, which restricts the operation of operators and easily leads to large measurement errors. Furthermore, during the measurement, the positions of the hydraulic cylinders on both sides need to be swung, which poses a safety hazard to the operators inside the rolling mill due to the swinging of the hydraulic cylinders. Moreover, the rolling mill must be stopped before changing rolls to perform centerline calibration, which affects production efficiency. In this embodiment, by setting a calibration block at the end of the roller table baffle, the measurement calibration block is used to replace the measurement hydraulic cylinder. The operator does not need to enter the rolling mill, eliminating the safety hazard. At the same time, the measurement of the calibration block position outside the rolling mill does not require stopping the machine, thus improving production efficiency.

[0047] In step S120, the measuring ruler is placed on the calibration block and makes contact with the calibration block.

[0048] In step S130, the vertical roller on the same side as the calibration block is moved so that the vertical roller bearing seat comes into contact with the measuring ruler.

[0049] In this embodiment, please refer to Figure 4 and Figure 5 The vertical roller bearing housing 8 includes a drive side 4 and an operating side 5. Roller conveyor baffles 9 are respectively disposed below the drive side 4 and the operating side 5. Specifically, the drive side 4 and the operating side 5 have protrusions. When the drive side 4 and the operating side 5 move, the protrusions and the measuring ruler are in contact. At this time, the vertical roller bearing housing 8 and the calibration block 6 are in a parallel state.

[0050] In step S140, the center of the vertical roll opening is marked as the vertical roll centerline. When the vertical roll bearing housing and the calibration block are in a parallel state, the centerline between the calibration blocks is the rolling center. The centerline between the calibration blocks coincides with the vertical roll centerline. After the vertical roll centerline coincides with the rolling centerline, the center of the vertical roll opening is the position of the vertical roll centerline.

[0051] Specifically, the opening degree of the vertical roller is A, and the distance between the center line of the vertical roller and the bearing seat 8 of the vertical roller is... The preset strip deviation value is 'a'. After the vertical roller centerline moves towards the drive side, the opening degree of drive side 4 is adjusted to... The opening of the operating side 5 is adjusted to The opening degree of the drive side 4 and the opening degree of the operating side 5 are calibrated. After the calibration is completed, the center line of the vertical roller is shifted to the drive side.

[0052] In step S150, the center line of the vertical roller is adjusted according to the preset strip deviation value.

[0053] In this embodiment, please refer to Figure 5 The vertical roller bearing housing 8 is equipped with a hydraulic cylinder 3 for driving and a balance cylinder 2 for stabilizing. The balance cylinder 2 balances and stabilizes the vertical roller bearing housing 8. The hydraulic cylinder 3 is activated to adjust the opening degree of the transmission side 4 and the operating side 5. The hydraulic cylinder 3 is retracted on the transmission side 4 and extended on the operating side 5, moving the center line of the vertical roller towards the transmission side 4. Because the hydraulic cylinder 3 on the transmission side 4 retracts, the opening degree of the transmission side 4 decreases, and the opening degree of the transmission side 4 needs to be increased to compensate. The opening degree of the operating side 5 needs to be decreased to compensate.

[0054] As can be seen, the technical solution provided in this embodiment no longer requires entering the rolling mill to measure the distance between hydraulic cylinders. By setting calibration blocks 6 at the ends of the roller table baffles 9 on both sides of the crossbeam of the vertical roll stand 1, the measurement can be performed using calibration blocks 6. The operator can perform the measurement without entering the rolling mill. The measuring ruler is placed on the calibration block 6 and in contact with it. The vertical roll on the same side as the calibration block 6 is moved so that the end face 7 of the vertical roll bearing seat is in contact with the measuring ruler, making the calibration block 6 parallel to the vertical roll bearing seat 8, ensuring the accuracy of the calibration results. The center of the vertical roll opening is calibrated as the vertical roll centerline. According to the preset strip deviation value, the vertical roll centerline is adjusted to compensate for the strip deviation distance during production. The calibration operation is simple and efficient, and there is no need to stop the rolling mill for calibration. The operator can complete the calibration operation outside the rolling mill, eliminating safety hazards and improving production efficiency.

[0061] The adjustment module 205 is configured to adjust the center line of the vertical roll according to the preset strip deviation value.

Measurements are taken using calibration blocks 6, allowing operators to perform measurements without entering the rolling mill. The measuring ruler is placed on the calibration block 6 and brought into contact with it. The vertical roll on the same side as the calibration block 6 is moved so that the end face 7 of the vertical roll bearing seat is in contact with the measuring ruler, making the calibration block 6 parallel to the vertical roll bearing seat 8. This ensures the accuracy of the calibration results. The center of the vertical roll opening is calibrated as the centerline of the vertical roll. The centerline of the vertical roll is adjusted according to the preset strip deviation value to compensate for the strip deviation distance during production. The calibration operation is simple and efficient, requiring no rolling stop for calibration.
