Description

TECHNICAL FIELD

[0001] The present application relates to the field of rolling mill technology, in particular to a method and device for calibrating the position of a coiler side guide. BACKGROUND

[0002] The coiler side guide is one of the important components in the rolling mill equipment, which functions to control the position in the width direction of the strip steel and ensure the plate shape, so as to align the strip steel with the rolling center line and guide the strip steel to smoothly enter the coiler. If the precision cannot be guaranteed, the quality of the coiled product will be affected, the product qualification rate will be reduced, and serious production accidents such as steel piling will be caused, which will affect the production progress.

[0003] At present, when checking and calibrating the actual position of the side guide, the side guide needs to be moved to a specific position after the coiler is stopped, and the distance between the two side guide edges is measured by the staff as the calibration value corresponding to the specific position. However, this method relies on the actual experience of the staff on site, and inevitably causes manual measurement errors. In addition, the side guide is installed on the column of the guide roller device and is opened and closed through the transverse movement of the guide roller system. The clearance between the column and the side guide is increased due to the mutual friction, and if the clearance is too large, the actual distance will be different from the calibration distance when the side guide actually moves, which will cause a decrease in precision.

[0049] In the description of the present application, it should also be noted that, unless otherwise explicitly specified and limited, the terms "arrange", "mount", "connect", "connect" should be understood broadly, for example, it can be fixedly connected, or it can be detachably connected, or integrally connected; it can be mechanically connected, or it can be electrically connected; it can be directly connected, or it can be indirectly connected through an intermediate medium, or it can be the communication inside two elements. For those of ordinary skill in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0050] The embodiments of the present application provide a coiler side guide plate position calibration method, which is combined with Figure 1 The coiler side guide plate position calibration method shown in the flowchart includes steps 101 to 105:

[0051] Step 101: After the coiler is stopped, the first side guide plate and the second side guide plate on the coiler are run inward to a first opening degree;

[0052] In this embodiment, the coiler is a device for winding metal strips (such as steel strips) into coils. When the coiler is working, the head of the steel strip is first introduced into the reel, and the steel strip is clamped by the expansion and contraction mechanism of the reel. Then, the transmission system drives the reel to rotate, and the steel strip is gradually wound on the reel under the driving of the reel. During the winding process, the tension control device monitors and adjusts the tension of the steel strip in real time, so that it remains within the set range. At the same time, the side guide plate guides and positions the strip to ensure that the strip is wound neatly.

[0053] The strip steel is conveyed by conveying rollers, and side guides, namely a first side guide and a second side guide, are arranged on the left and right sides above the conveying rollers. The side guides are used to ensure the stability and directionality of the strip steel during the running process, accurately guide the strip steel after the laminar cooling to the coiler for coiling, re-center the strip steel before entering the coiler, ensure that the strip steel can enter along the center line of the coiler, thereby obtaining a good coil shape and avoiding problems such as uneven coiling and tower shape caused by deviation of the strip steel.

[0054] The side guides are also used to clamp the strip steel during the coiling process, prevent the strip steel from swinging or shifting left and right during the coiling, maintain the stable position of the strip steel during the coiling process, help to control the shape and dimensional accuracy of the coil, improve the coiling quality, and ensure smooth threading and stable coiling of the strip steel.

[0055] As shown in Figure 2 The first side guide and the second side guide run to a certain opening, which can be understood as the first side guide and the second side guide moving to a certain position. At this time, the distance between the first side guide and the second side guide is the opening, which is generally slightly larger than the width of the strip steel.

[0056] When checking and calibrating the actual position of the side guide, the coiler needs to be stopped, and the strip steel is not coiled at this time. At this time, the first side guide and the second side guide run inward to the first opening. The first opening can be randomly set, and the first opening is not the maximum opening.

[0057] Step 102: based on the rolling center line on the conveying roller, the first distance of the first side guide and the second side guide at the strip steel inlet end and the second distance at the strip steel outlet end are measured respectively;

[0058] Wherein, one end of the strip steel entering the whole conveying roller is the strip steel inlet end, and one end of the strip steel leaving the whole conveying roller is the strip steel outlet end.

[0059] During the coiling process of the strip steel, the conveying roller is not changed in position. As shown in Figure 3 The first side guide and the second side guide run outward to the maximum opening, which is used to completely expose the conveying roller; the maximum opening refers to the maximum distance between the first side guide and the second side guide.

[0060] There are multiple conveying rollers on the coiler, and the center points of at least two conveying rollers are determined in the embodiment; the rolling center line is determined according to the center points of the at least two conveying rollers.

[0061] When initially calibrating the position of the side guide of the coiler, the rolling center line is positioned. When subsequently calibrating the position of the side guide of the coiler, the previously positioned rolling center line can be directly used for convenience.

[0062] Since the first side guide plate and the second side guide plate are long, a first distance of the guide plate at the strip steel inlet end and a second distance of the guide plate at the strip steel outlet end are measured. If the first side guide plate is parallel to the second side guide plate, the first distance and the second distance are substantially equal.

[0063] It should be noted that the first opening degree is a theoretical value of the coiler control system, and the first distance and the second distance are actual distance values measured when the first side guide plate and the second side guide plate are executed. The purpose of the calibration in the embodiment is to calibrate the theoretical value with the actual value to ensure the control accuracy of the coiler.

[0064] Step 103: After running the first side guide plate and the second side guide plate inward to a second opening degree, the first side guide plate and the second side guide plate are run outward to the first opening degree; wherein the first opening degree is greater than the second opening degree.

[0065] It should be noted that the side guide plate is installed on the column of the guide roller device, and is opened and closed (i.e. the opening degree is changed) by the transverse movement of the guide roller device. Specifically, the bottom of the side guide plate is provided with an inlet end column hole and an outlet end column hole, and the side guide plate is connected with the column of the guide roller device through the inlet end column hole and the outlet end column hole. In the long-term use process, the column and the column hole cause the clearance to increase due to mutual friction, and finally may cause an error between the actual distance and the theoretical opening degree when the side guide plate actually acts, causing the control accuracy to decrease.

[0066] Based on the above situation, the first side guide plate and the second side guide plate are run inward to the second opening degree after being run to the first opening degree, so that the distance between the first side guide plate and the second side guide plate is reduced. Then, the first side guide plate and the second side guide plate are reversely run outward to the position of the first opening degree.

[0067] Step 104: Based on the rolling center line on the conveying roller, a third distance of the first side guide plate at the strip steel inlet end and a fourth distance of the second side guide plate at the strip steel outlet end are measured respectively.

[0068] It can be seen that if there is a large clearance, the distance value measured after the second running of the side guide plate to the first opening degree is slightly smaller than the distance value corresponding to the first running to the first opening degree, i.e. the third distance is smaller than the first distance or the fourth distance is smaller than the second distance. If there is no clearance (or the clearance is very small), the distance values measured twice are substantially equal.

[0069] In an optional embodiment, the clearance of the column can be determined by referring to the following steps:

[0070] According to the first distance and the third distance, the clearance of the inlet end column hole is determined.

[0071] According to the second distance and the fourth distance, the clearance of the exit end post hole is determined.

[0072] If the clearance of the exit end post hole is greater than a second threshold value, an alarm is sent.

[0073] The difference between the first distance and the third distance can be considered as the clearance of the two entry end post holes. The difference between the second distance and the fourth distance can be considered as the clearance of the two exit end post holes.

[0074] If the calculated post hole clearance is large, for example, the clearance of the entry end post hole is greater than a first threshold value, or the clearance of the exit end post hole is greater than a second threshold value, the actual action of the first side guide plate and the second side guide plate will cause a large error between the actual distance and the calibrated distance, resulting in a decrease in precision and affecting the quality of the coiled strip. Therefore, if the clearance of the entry end post hole is greater than a first threshold value, or the clearance of the exit end post hole is greater than a second threshold value, an alarm is sent to remind the staff to repair in time.

[0075] Step 105: According to the first distance, the second distance, the third distance and the fourth distance, the calibrated distance corresponding to the first opening degree is determined.

[0076] In consideration of safety in production, the smallest distance is selected from the first distance, the second distance, the third distance and the fourth distance, and the selected smallest distance is taken as the calibrated distance corresponding to the first opening degree.

[0077] After calibration, if the first side guide plate and the second side guide plate are controlled to run to the first opening degree in the subsequent coiling control process, the actual distance between the first side guide plate and the second side guide plate after movement is the calibrated distance.

[0078] In an optional embodiment, the alignment of the first side guide plate relative to the rolling center line is also measured, and the alignment of the second side guide plate relative to the rolling center line is also measured. The specific steps include:

[0079] According to the first distance and the second distance, the alignment of the first side guide plate and the second side guide plate is determined.

[0080] The first distance includes a fifth sub-distance and a sixth sub-distance, that is, the first distance is the sum of the fifth sub-distance and the sixth sub-distance. The fifth sub-distance refers to the distance between the first side guide plate at the entry end of the strip and the rolling center line, and the sixth sub-distance refers to the distance between the second side guide plate at the entry end of the strip and the rolling center line.

[0081] In the embodiment, the alignment degree of the first side guide plate and the second side guide plate at the strip steel inlet end can be determined according to the fifth sub-distance and the sixth sub-distance. It can be understood that the closer the fifth sub-distance and the sixth sub-distance are to each other, the better the alignment degree of the first side guide plate and the second side guide plate at the strip steel inlet end.

[0082] The second distance includes a seventh sub-distance and an eighth sub-distance, that is, the second distance is the sum of the seventh sub-distance and the eighth sub-distance. The seventh sub-distance refers to the distance between the first side guide plate and the rolling center line at the strip steel outlet end, and the eighth sub-distance refers to the distance between the second side guide plate and the rolling center line at the strip steel outlet end.

[0083] In the embodiment, the alignment degree of the first side guide plate and the second side guide plate at the strip steel outlet end can be determined according to the seventh sub-distance and the eighth sub-distance. It can be understood that the closer the seventh sub-distance and the eighth sub-distance are to each other, the better the alignment degree of the first side guide plate and the second side guide plate at the strip steel outlet end.

[0084] In addition, if the two side guide plates are not parallel, it will cause the strip steel to be subjected to uneven lateral force during the coiling process, and the strip steel will be deviated. This will cause the edges of the coil to be uneven, and defects such as tower-shaped coil and staggered layers will occur, affecting the appearance quality of the coil and subsequent use, causing difficulties in subsequent cutting, packaging and other processes, and even causing the steel strip to be scrapped.

[0085] Based on the above situation, the parallelism of the first side guide plate and the second side guide plate is measured in the embodiment. The parallelism of the first side guide plate and the second side guide plate can be determined according to the first distance and the second distance. The specific steps can include:

[0086] calculating the difference between the first distance and the second distance;

[0087] Based on the preset target difference range, the parallelism of the first side guide plate and the second side guide plate is determined according to the difference.

[0088] In some hot rolling coilers, the parallelism requirement of the side guide plate is generally less than or equal to 5 mm / m, that is, the parallelism deviation per meter is not more than 5 mm. The parallelism of the improved high-precision coiler side guide plate can reach 1-2 mm from the inlet end to the outlet end. The target difference range in the embodiment can be set based on the actual situation and reference to the above content. If the difference is within the target difference range, it is considered that the parallelism of the first side guide plate and the second side guide plate is good.

[0089] In summary, the coiler side guide plate position calibration method provided by the embodiments of the present specification is as follows: after the coiler is stopped, the first side guide plate and the second side guide plate on the coiler are run inward to a first opening degree; based on the rolling center line on the conveying roller, the first distance of the first side guide plate and the second side guide plate at the strip steel inlet end and the second distance at the strip steel outlet end are measured respectively; after the first side guide plate and the second side guide plate are run inward to a second opening degree, the first side guide plate and the second side guide plate are run outward to the first opening degree; wherein the first opening degree is greater than the second opening degree; based on the rolling center line on the conveying roller, the third distance of the first side guide plate and the second side guide plate at the strip steel inlet end and the fourth distance at the strip steel outlet end are measured respectively; and the calibration distance corresponding to the first opening degree is determined according to the first distance, the second distance, the third distance and the fourth distance. In this way, the actual position of the side guide plate can be accurately measured and calibrated, the manual measurement error is reduced, the coiling quality of the rolled product is ensured, and the production efficiency is improved.
