Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of steel rolling, in particular to a coiler working condition monitoring method, device, medium and equipment. BACKGROUND

[0002] The coiler roll of a hot continuous rolling sheet line works in a harsh environment of high temperature, high humidity, high pressure and high speed for a long time, and the corrosion and wear of each component are relatively fast. The position measurement device also has a zero drift phenomenon due to frequent impact and high pressure work. These phenomena cannot be found due to inaccurate roll gap calibration, which increases the roll gap deviation of the coiler roll. When the deviation value accumulates to the point that it cannot meet the production requirements of the variety and specifications, product quality or production accidents will occur. Common problems include difficulty in biting the head due to the actual roll gap being too small, or the coiler roll of a thin specification hitting the core shaft and causing power failure and steel stacking; the actual roll gap is too large, the head bites and slips, which may cause a tower-shaped coil or even a steel stacking accident.

[0003] Therefore, in continuous production, how to determine whether the working condition of the coiler can meet the requirements of subsequent planned stable production and ensure high-quality and stable production of the strip steel is a technical problem to be solved. SUMMARY

[0024] Example implementations will now be described more fully with reference to the accompanying drawings. Example implementations may, however, be implemented in many different forms and should not be construed as limited to the implementations set forth herein; rather, these implementations are provided so that this disclosure will be thorough and complete, and will fully convey the scope of example implementations to those skilled in the art.

[0025] Moreover, the described features, structures, or characteristics can be combined in any suitable manner in one or more embodiments. In the following description, numerous specific details are provided to give a thorough understanding of embodiments of the application. One skilled in the relevant art will recognize, however, that the

[0026] The flow charts shown in the drawings are only illustrative, and do not necessarily include all the contents and operations / steps, nor do they have to be executed in the order described. For example, some operations / steps can be further decomposed, and some operations / steps can be combined or partially combined, so the actual execution order can be changed according to actual conditions.

[0027] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such uses of these terms can be interchanged where appropriate so that the embodiments of this application described herein can be implemented in orders other than those illustrated or described.

[0028] In this application, the coiler mainly consists of a coiler mandrel, gearbox, motor, etc. The coiler mandrel is surrounded by several sector plates, which open to form the outer ring of the coiler mandrel. The coiler is used to coil strip steel into a roll shape. The auxiliary coiling roller is used to accurately deliver the head of the strip steel to the mandrel of the coiler, press the strip steel onto the mandrel with appropriate clamping force to increase the coiling tightness, apply bending processing to the strip steel to make it into a shape that is easy to coil, and press the tail end to prevent the tail of the strip steel from curling up and loosening. Through the joint operation of the coiler roll and the auxiliary coiling roller, the coiling rate and quality of the strip steel are guaranteed.

[0029] In this application, because the auxiliary winding roller operates continuously in a harsh environment of high temperature, high humidity, high pressure and high speed for a long time, the corrosion and wear of each component are relatively fast; the frequent impact of the strip head and high pressure operation will also cause the zero drift of the position measuring device; inaccurate roll gap calibration will not be detected. All of these factors increase the roll gap deviation of the auxiliary winding roller. When the deviation value accumulates to the point that it cannot meet the requirements of the product variety and specifications, product quality or production accidents will occur.

[0030] In this application, in order to ensure the quality of the strip and the stability of production when the coiler is coiling the strip, it is necessary to monitor the working condition of the coiler in real time. The coiler working condition monitoring method, device, medium and equipment proposed in this application can quickly judge the working condition of the coiler during normal production.

[0031] The implementation details of the technical solutions in the embodiments of this application are described in detail below:

[0032] Reference Figure 1 , Figure 1 This is a flowchart of a method for monitoring the operating conditions of a winding machine according to one embodiment of this application.

[0033] According to a typical embodiment of this application, a method for monitoring the operating condition of a winding machine is provided, the method comprising the following steps S1 to S3:

[0034] Step S1: After the roll gap value between the auxiliary winding roller and the mandrel in the working state has been properly calibrated, calculate the roll gap value when the auxiliary winding roller is adjusted to the maximum opening, and use it as the reference value for monitoring the roll gap deviation.

[0035] Step S2, calculate the roll gap value of the roll assist roller at the maximum opening as a detection value for monitoring the roll gap deviation, based on the working cycle of the coiler.

[0036] Step S3, monitor the roll gap between the roll assist roller and the mandrel in the working state based on the detection value and the reference value.

[0037] In this application, the roll gap value between the roll assist roller and the mandrel in the working state is calibrated, after the calibration is completed, the roll gap between the roll assist roller and the mandrel is adjusted to the maximum opening, and the roll gap value of the roll assist roller and the mandrel after the roll gap is adjusted to the maximum opening is calculated, the roll gap value is taken as the reference value for monitoring the roll gap deviation, to judge whether the roll gap between the roll assist roller and the mandrel in the working state deviates in the subsequent production.

[0038] In this application, in the calculation of the roll gap value between the roll assist roller and the mandrel after the roll gap is adjusted to the maximum opening, the roll gap value is taken as the reference value for monitoring the roll gap deviation between the roll assist roller and the mandrel, in the working cycle of the coiler, when the roll gap between the roll assist roller and the mandrel is adjusted to the maximum opening (such as when the coiler is unloaded, the roll assist roller is automatically opened to the maximum, at this time the roll gap between the roll assist roller and the mandrel is at the maximum opening), the roll gap value of the roll assist roller at the maximum opening is calculated as a detection value for monitoring the roll gap deviation, based on the detection value and the reference value, the roll gap between the roll assist roller and the mandrel in the working state can be monitored, when the detection value deviates from the reference value, it means that the roll gap between the roll assist roller and the mandrel in the working state may also deviate, and it needs to be determined whether the roll gap value between the roll assist roller and the mandrel in the working state needs to be recalibrated according to the actual situation.

[0039] In this application, it should be noted that due to the long-term, continuous work of the roll assist roller in the harsh environment of high temperature, high humidity, high pressure and high speed, the roll gap value between the roll assist roller and the mandrel in the working state may deviate, once the deviation value accumulates to the extent that it cannot meet the production requirements of varieties and specifications, product quality or production accidents will occur, therefore, after the roll assist roller works for a period of time, the roll gap value between the roll assist roller and the mandrel in the working state needs to be calibrated to ensure the stability and continuity of production.

[0040] In an embodiment of the present application, the roll gap between the roll assist roller and the mandrel is controlled by driving the roll assist roller through a hydraulic cylinder, and the calculation of the roll gap value of the roll assist roller at the maximum opening includes:

[0041] acquiring a contraction stroke of the hydraulic cylinder when the roll-up assisting roller is adjusted to the maximum opening.

[0042] calculating the roll gap value when the roll-up assisting roller is adjusted to the maximum opening according to the contraction stroke through a functional relationship between the roll gap value and the contraction stroke.

[0043] In the present application, the roll gap between the roll-up assisting roller and the mandrel is controlled by driving the roll-up assisting roller through the hydraulic cylinder. When calculating the roll gap value when the roll-up assisting roller is adjusted to the maximum opening, the hydraulic cylinder first drives the roll-up assisting roller to the maximum opening, and then the contraction stroke of the hydraulic cylinder is acquired after the roll-up assisting roller is adjusted to the maximum opening. Then, the roll gap value when the roll-up assisting roller is adjusted to the maximum opening is calculated according to the contraction stroke through a functional relationship between the roll gap value and the contraction stroke. It should be noted that after the roll gap value between the roll-up assisting roller and the mandrel in the working state is normally calibrated, the calculation method for calculating the roll gap value when the roll-up assisting roller is adjusted to the maximum opening is the same as the calculation method used for calculating the roll gap value when the roll-up assisting roller is adjusted to the maximum opening based on the working cycle of the coiler. Both of them are calculated according to the contraction stroke of the hydraulic cylinder through a functional relationship between the roll gap value and the contraction stroke, and the maximum opening of the roll-up assisting roller remains unchanged.

[0044] In the present application, it should be noted that when calculating the roll gap value when the roll-up assisting roller is adjusted to the maximum opening, the control program can calculate the roll gap value when the roll-up assisting roller is adjusted to the maximum opening according to a functional relationship between the roll gap value and the contraction stroke, and then display the roll gap value on the operation display interface of the equipment, so that the operator can intuitively and real-timely understand the roll gap value between the roll-up assisting roller and the mandrel. When the roll gap value deviates, it can be found and processed in time, so as to realize real-time monitoring of the roll gap value in actual production, and ensure the stable production and quality of the subsequent strip steel, and the production efficiency of the unit.

[0045] In an embodiment of the present application, the monitoring of the roll gap between the roll-up assisting roller and the mandrel in the working state based on the detection value and the reference value comprises:

[0046] If the detection value is greater than the reference value, it is determined that the roll gap value between the roll-up assisting roller and the mandrel in the working state is too small.

[0047] If the detection value is less than the reference value, it is determined that the roll gap value between the roll-up assisting roller and the mandrel in the working state is too large.

[0048] In the present application, with reference to Figure 2 , the roll gap value between the roll-up assisting roller and the mandrel in the working state is monitored based on the detection value and the reference value. Figure 2Taking a middle three-roller assisting roll as an example, after the roll gap value between the assisting roll 101 and the mandrel 103 in a working state is normally calibrated, the hydraulic cylinder 102 controls the assisting roll 101 to be adjusted to the maximum opening, when the hydraulic cylinder 102 controls the assisting roll 101 to be adjusted to the maximum opening, the retraction stroke of the hydraulic cylinder 102 is obtained, and according to the retraction stroke, the roll gap value when the assisting roll 101 is adjusted to the maximum opening is calculated through the functional relationship between the roll gap value and the retraction stroke of the hydraulic cylinder 102, and the roll gap value is taken as the reference value for monitoring the roll gap deviation; after the coiler works for a period of time, the roll gap value between the assisting roll 101 and the mandrel 103 may deviate, once the deviation value accumulates to the extent that the product quality or production accident cannot be satisfied, the product quality or production accident occurs, and the assisting roll 101 needs to be recalibrated.

[0049] In the present application, continue to refer to Figure 2 , in order to better understand, it is assumed that after the roll gap value between the assisting roll 101 and the mandrel 103 in a working state is normally calibrated, the hydraulic cylinder 102 controls the assisting roll 101 to be opened to the maximum opening, at this time the retraction stroke of the hydraulic cylinder 102 obtained is 800mm, according to the retraction stroke of the hydraulic cylinder 102, the roll gap value when the assisting roll 101 is adjusted to the maximum opening is calculated through the functional relationship between the roll gap value and the retraction stroke of the hydraulic cylinder 102, and the roll gap value is taken as the reference value for monitoring the roll gap deviation.

[0050] In the present application, continue to refer to Figure 2When the assisting winding roller 101 works for a certain period, the roll gap value between the assisting winding roller 101 and the mandrel 103 can be deviated. When the coiler is uncoiling, the assisting winding roller 101 is automatically opened to the maximum opening degree, and the contraction stroke of the hydraulic cylinder 102 is obtained at this time. The contraction stroke of the hydraulic cylinder 102 obtained can be greater than or less than 800 mm (the normal contraction stroke of the hydraulic cylinder 102 should be 800 mm when the assisting winding roller 101 is opened to the maximum opening degree) due to the zero drift of the position measuring device in the hydraulic cylinder 102 or other reasons. According to the contraction stroke of the hydraulic cylinder 102 obtained, the roll gap value of the assisting winding roller 101 when the assisting winding roller 101 is adjusted to the maximum opening degree is calculated through the functional relationship between the roll gap value and the contraction stroke. At this time, the roll gap value is a detection value. Since the roll gap value of the assisting winding roller 101 when the assisting winding roller 101 is adjusted to the maximum opening degree is calculated according to different contraction strokes of the hydraulic cylinder 102, the detection value is deviated from the reference value, and the assisting winding roller 101 needs to be recalibrated.

[0051] In this application, continue to refer to Figure 2 If the contraction stroke of the hydraulic cylinder 102 obtained is greater than 800 mm, the roll gap value of the roll gap between the assisting winding roller 101 and the mandrel 103 in the working state is calculated according to the contraction stroke through the functional relationship between the roll gap value and the contraction stroke. At this time, the roll gap value calculated is a detection value, and the detection value is greater than the reference value, so it is determined that the roll gap value between the assisting winding roller 101 and the mandrel 103 in the working state is too small (since the maximum opening degree of the assisting winding roller 101 is always unchanged, when the contraction stroke of the hydraulic cylinder 102 is greater than 800 mm, the hydraulic cylinder 102 controls the assisting winding roller 101 to close to the working state, and the contraction stroke of the hydraulic cylinder 102 is also kept corresponding to the stroke, so that the roll gap value between the assisting winding roller 101 and the mandrel 103 in the working state is too small). Similarly, if the detection value is less than the reference value, it is determined that the roll gap value between the assisting winding roller 101 and the mandrel 103 in the working state is too large.

[0052] In this application, continue to refer to Figure 2 It should be noted here that Figure 2 The assisting winding roller shown in the figure is only one embodiment of the present application. The assisting winding roller can also be a two-roller assisting winding roller, a four-roller assisting winding roller, or other types of assisting winding rollers, which are not particularly limited in the present application, Figure 2 The working condition monitoring methods of the other several assisting winding rollers in the figure are the same as those of the assisting winding roller 101.

[0053] In one embodiment of the present application, the method further comprises: if it is determined that the roll gap value between the assisting roll and the mandrel in the working state is too large or too small, calculating a deviation value between the reference value and the detected value.

[0054] According to the deviation value, a deviation reason for the deviation between the reference value and the detected value is predicted.

[0055] If the deviation value is less than a first threshold value, the deviation reason includes a calibration drift of the coiler; if the deviation value is greater than or equal to the first threshold value and less than or equal to a second threshold value, the deviation reason includes the calibration drift of the coiler or a failure of a fixed part of the coiler; and if the deviation value is greater than the second threshold value, the deviation reason includes the failure of the fixed part of the coiler.

[0056] In the present application, when it is determined that the roll gap value between the assisting roll and the mandrel in the working state is too large or too small, a deviation value between the reference value and the detected value is calculated, for example, the reference value is 2 mm, the detected value is 2.3 mm, and the deviation value between the reference value and the detected value is calculated to be 0.3 mm. According to the deviation value between the reference value and the detected value, a deviation reason for the deviation between the reference value and the detected value can be predicted, and the problem can be quickly determined according to the reason for the deviation, and handled quickly to ensure the smooth progress of production. If the deviation value is less than a first threshold value, the deviation reason can include a calibration drift of the coiler; if the deviation value is greater than or equal to the first threshold value and less than or equal to a second threshold value, the deviation reason can include the calibration drift of the coiler or a failure of a fixed part of the coiler; and if the deviation value is greater than the second threshold value, the deviation reason can include the failure of the fixed part of the coiler.

[0057] In one embodiment of the present application, the method further comprises: if it is determined that the roll gap value between the assisting roll and the mandrel in the working state is too large or too small, calculating a deviation value between the reference value and the detected value; and obtaining a strip thickness of the strip coiled by the coiler in the working cycle.

[0058] In the present application, after the deviation value between the reference value and the detected value is calculated, the probability of the coiler being at risk when performing a production action is predicted according to the strip thickness and the deviation value, wherein the probability is inversely proportional to the strip thickness and proportional to the deviation value. It is noted that the greater the calculated deviation value, the greater the probability of the coiler being at risk when performing a production action. For example, if the calculated deviation value is 0.2 mm, it is tolerable for subsequent production of thick gauge strips. For example, when producing 10 mm strips, a deviation value of 0.2 mm is tolerable and the coiler does not need to be recalibrated. However, if the deviation value is 0.2 mm, it is not tolerable for production of 2.1 mm strips and the coiler needs to be recalibrated. The thinner the strip, the lower the tolerance for the deviation value.

[0059] In an embodiment of the present application, the method further comprises predicting the type of risk of the coiler when performing a production action according to the strip thickness and the deviation value, and triggering a warning prompt corresponding to the type of risk.

[0060] In an embodiment of the present application, predicting the type of risk of the coiler when performing a production action according to the strip thickness and the deviation value comprises:

[0061] If the strip thickness is less than 2.5 mm and the deviation value of the detected value from the reference value is 2 mm, it is predicted that the type of risk of the coiler when performing a production action is slipping of the strip during coiling.

[0062] If the strip thickness is less than 2.5 mm and the deviation value of the detected value from the reference value is 1.5 mm, it is predicted that the type of risk of the coiler when performing a production action is collision of the coiler with the mandrel.

[0063] In the present application, the type of risk of the coiler when performing a production action can be predicted according to the strip thickness and the deviation value. For example, when producing thin gauge strips, the deviation value is too large, which may result in a slipping accident of the strip head. If the strip thickness is less than 2.5 mm and the deviation value of the detected value from the reference value is 2 mm, it is predicted that the type of risk of the coiler when performing a production action is slipping of the strip during coiling. For example, when producing thick gauge strips, the deviation value is too small, which may result in a piling accident of the strip head. If the strip thickness is less than 2.5 mm and the deviation value of the detected value from the reference value is 1.5 mm, it is predicted that the type of risk of the coiler when performing a production action is collision of the coiler with the mandrel.

[0064] In the present application, it is necessary to note that when it is determined that the roll gap value between the winding-up roller and the mandrel in the working state is too large or too small, the deviation value between the reference value and the detected value is calculated, if the deviation value does not meet the production of the subsequent strip steel, the roll gap value between the winding-up roller and the mandrel in the working state needs to be re-calibrated, the winding-up roller is re-calibrated by using the roll changing time, and if the deviation value still does not meet the production of the subsequent strip steel after calibration for multiple times, relevant professionals are informed to handle the equipment, or the production plan is adjusted in advance to avoid affecting the normal production plan of the strip steel.
