Description

Technical Field

[0001] This application relates to the field of strip coiling technology, and in particular to a side guide plate control method, device, medium, and equipment. Background Technology

[0002] If the strip head is bent into a sickle shape during the coiling process, it can easily lead to a jamming accident.

[0003] Currently, when the camber at the head of the strip exceeds the standard, the main method to reduce the probability of strip jamming is to manually open the side guide plate. However, on the one hand, failure to detect the camber or insufficient opening of the side guide plate in time can still easily cause strip jamming accidents. On the other hand, if the side guide plate is opened too wide, there is also a risk of increased incidence of internal towering. Summary of the Invention

[0035] It should be noted that a finishing mill, a laminar flow cooling roller table, pinch rolls and a coiler are arranged sequentially along the length of the strip, with two side guide plates arranged opposite each other on both sides of the laminar flow cooling roller table.

[0036] In some embodiments, detecting the offset of the strip head in the width direction of the strip includes: acquiring at least two sets of reference positions of the strip head in the length direction, each set of reference positions including two reference positions disposed opposite to each other in the width direction of the strip; for each set of reference positions, acquiring target center lines of the two reference positions in the width direction of the strip; for each target center line, determining the center offset of the target center line from other target center lines in the width direction of the strip; and taking the maximum value among the plurality of center offsets as the offset of the strip head in the width direction of the strip.

[0041] In some embodiments, the formula for calculating the distance between the head of the strip and the pinch roll is as follows: , This is the distance between the head of the strip and the pinch roll. For the target distance, This represents the current distance.

[0042] In some implementations, the formula for calculating the current distance is as follows: , The time after the strip leaves the finishing mill. After the strip leaves the finishing mill The speed at any given moment. The current distance can also be understood as the tracking distance of the strip head at F7.

[0043] In some embodiments, when the pinch roll has a tracking signal of the strip head or the pressure generated by the pinch roll is greater than 25KN, the pinch roll generates a bite signal, that is, the pinch roll biting the strip is detected.

For each set of reference positions, obtain the target centerline of the two reference positions in the strip width direction; For each target centerline, the center offset of the target centerline from other target centerlines in the width direction of the strip is determined. The maximum value among the multiple center offsets is taken as the offset of the head of the strip in the width direction of the strip.

8. A side guide plate control device, characterized in that, A finishing mill, a side guide plate assembly, and a coiler are sequentially arranged along the length of the strip. The side guide plate assembly includes two side guide plates spaced apart from each other along the width of the strip. The device includes: The first detection unit detects the amount of offset of the head of the strip in the width direction of the strip when the head of the strip leaves the exit of the finishing mill. If the offset is greater than or equal to a preset offset threshold, the first increasing unit increases the distance between the two side guide plates in the width direction of the strip from a first distance to a second distance, wherein the first distance is greater than or equal to the sum of the width of the strip and the offset threshold. The first reducing unit, upon detecting a bite signal from the coiler onto the strip, reduces the distance between the two side guide plates in the width direction of the strip to a third distance, the third distance being equal to the width of the strip.

9. A computer-readable storage medium having a computer program stored thereon, characterized in that, The computer program includes executable instructions that, when executed by a processor, implement the method of any one of claims 1-7.

10. An electronic device, characterized in that, include: One or more processors; A memory for storing executable instructions of the processor, which, when executed by the one or more processors, cause the one or more processors to perform the method according to any one of claims 1-7.
