Description

Technical Field

[0001] This application relates to the field of strip rolling technology, and in particular to a method, apparatus, medium, and electronic equipment for detecting the spatial position of a rolling mill. Background Technology

[0002] Due to the complexity of the roll system, extremely high spatial positioning accuracy of the inner arches is required to ensure the high symmetry of the rolls. Currently, micrometers are commonly used to measure the diagonals of the upper and lower inner arches, which requires a high level of skill and personal experience from the measuring personnel and is not easily replicable. Simultaneously, during production, the 20-roll mill is a reversible, high-tension coiling and rolling mill. The copper liners on the inner arches experience varying degrees of wear under rolling line adjustments and strip tension, which cannot be detected in real time. If the liner wear is inconsistent, exceeds the standard, or if there is an abnormality in the clearance-eliminating hydraulic cylinder, causing the inner arches to shift, the rolls will roll asymmetrically, resulting in strip warping. This severely affects the strip shape and may even prevent subsequent annealing unit production. Summary of the Invention

The character " / " generally indicates that the preceding and following related objects have an "or" relationship.

[0041] The implementation details of the technical solutions in the embodiments of this application are described in detail below:

[0042] First, it should be noted that the rolling mill spatial position detection scheme proposed in this application can be applied to related technical fields of strip rolling. By using the initial position data of the rolling mill arch and the real-time position data of the arch after a shift, it can be determined whether the spatial position of the arch has changed inaccurately. Furthermore, the accuracy of the rolling mill's spatial position can be detected based on the real-time initial position data and the real-time position data. The rolling mill spatial position detection method provided in this application can solve the problem of strip shape being affected by shifts in the arch's position.

[0043] According to one aspect of this application, a method for detecting the spatial position of a rolling mill is provided. Figure 1 The flowchart below shows a method for detecting the spatial position of a rolling mill according to an embodiment of this application. This method includes at least steps 110 to 130, which are described in detail below:

[0044] In step 110, the initial position data of the archway of the rolling mill is obtained.

[0045] Specifically, the roll forming system comprises an inner roll forming system and an outer roll forming system. The inner roll forming system further includes an upper inner roll forming system and a lower inner roll forming system. The upper and lower inner roll forming systems can move up and down within the outer roll forming system. Six and four backlash-eliminating hydraulic cylinders are respectively installed on the entrance and drive sides of the outer roll forming system to eliminate sliding gaps between the inner and outer roll forming systems and to control rolling tension. This inevitably leads to wear on the steel and copper liners on the exit side. When wear exceeds the limit or the backlash-eliminating hydraulic cylinders malfunction, the upper and lower inner roll forming systems will shift, causing the strip to warp. A high-precision micrometer is installed on the backlash-eliminating hydraulic cylinders and fixed to them using a locking device. The displacement of the upper steel liners on the upper and lower inner roll forming systems is measured by a probe. The measured values ​​are displayed on the HMI screen on the host computer via a transmission cable, enabling real-time dynamic monitoring. Combined with the matching structure of the steel and copper liners, timely adjustments are made to correct symmetry, thereby improving the strip warping caused by roll misalignment.

[0046] In one embodiment of this application, see Figure 2 Step 110 can be performed according to the following steps S1-S2:

[0047] Step S1: Obtain the first relative position data of the inner archway and the outer archway, as well as the initial position data of the inner archway.

[0048] Step S2: Based on the initial position data of the inner archway and the first relative position data, the initial position data of the archway is obtained.

[0049] Continue to refer to Figure 1 In step 120, the strip steel is rolled on the rolling mill to obtain the real-time position data of the archway.

[0050] Specifically, the strip steel can be rolled to detect changes in the spatial displacement of the archway before and after rolling. Many factors can cause warping during strip steel rolling. Furthermore, due to the complex roll system of a 20-roll mill, troubleshooting is difficult once warping or other abnormalities occur. Without removing rolls, the archway's accuracy cannot be measured, making it impossible to immediately pinpoint its spatial position and the root cause of the problem. This inevitably impacts batch quality during roll change cycles.

[0051] In one embodiment of this application, obtaining the real-time location data of the archway can be performed according to steps S3-S4:

[0052] Step S3: Obtain the second relative position data of the inner archway and the outer archway, as well as the final position data of the inner archway.

[0053] Step S4: Based on the inner archway and the final location data, derive the real-time location data of the archway.

[0054] Specifically, the real-time position data of the archway is obtained by acquiring the inner archway and the final position data, taking the second relative position data between the inner archway and the outer archway and the final position data of the inner archway, and then using the inner archway and the final position data to obtain the real-time position data of the archway.

[0055] See also Figure 1 In step 130, the accuracy of the spatial position of the rolling mill is detected based on the real-time initial position data and the real-time position data.

[0056] In one embodiment of this application, step S130 may be performed according to steps S5-S6:

[0057] Step S5: Based on the real-time initial position data and the real-time position data, derive the spatial position change data of the archway.

[0058] Step S6: Detect the accuracy of the spatial position of the rolling mill based on the spatial position change data.

[0059] Specifically, the spatial position change data of the archway is derived based on the real-time initial position data and the real-time position data. The position data of the archway before and after the test can be compared to obtain the spatial position change data. The accuracy of the rolling mill's spatial position is then tested using the spatial position change data.

[0060] In one embodiment of this application, detecting the accuracy of the spatial position of the rolling mill based on the spatial position change data includes:

[0061] If the spatial position change data is within the preset data change range, the accuracy of the spatial position of the rolling mill is determined to be qualified;

[0062] If the spatial position change data is not within the range of data changes, the accuracy of the spatial position of the rolling mill is determined to be unqualified.

[0063] Specifically, the preset data change range can be set according to actual needs. If the spatial position change data is within the preset data change range, the accuracy of the spatial position of the rolling mill is determined to be qualified; otherwise, if the spatial position change data is not within the preset data change range, the accuracy of the spatial position of the rolling mill is determined to be unqualified.

[0064] In one embodiment of this application, steps 140-160 may also be performed:

[0065] Step 140: If the spatial position change data is not within the range of data change, send an alarm message to the terminal indicating that the accuracy of the rolling mill is insufficient.

[0066] Step 150: Analyze the real-time initial location data and the real-time location data to obtain an analysis data report.

[0067] Step 160: Upload the analysis data report to the cloud server.

[0068] Specifically, an early warning can be issued by sending an alarm message to the terminal indicating insufficient accuracy of the rolling mill. Simultaneously, the obtained position data can be analyzed and uploaded to a cloud server for later retrieval.
