Abstract
Description
Technical Field
[0001] This application relates to the field of strip rolling technology, and more specifically, to a monitoring method, device, medium, and electronic equipment for rolling equipment. Background Technology
[0002] In the production process, the looper is a key piece of equipment, mainly used to adjust and control the strip tension. The proper functioning of the looper's work rolls directly affects product quality. The looper work rolls play a crucial role in the operation and are in direct contact with the strip. A looper unit consists of an upper looper roll group and a lower looper roll group. Generally, the lower looper roll group is mounted on a fixed base, while the upper looper roll group is controlled by a control system to adjust its vertical position and thus the strip tension. Because of the dynamic changes in the upper looper, it is often difficult to install inspection equipment. The looper unit is often an area that is difficult to inspect and check. The looper work rolls rotate under the tension of the strip. Due to the uneven tension on both sides, axial forces can easily cause the looper rolls to veer to the sides, eventually leading to roll breakage. If not detected in time, this can cause the fault to escalate and even damage other equipment, increasing troubleshooting time and reducing operating efficiency.
[0003] Therefore, those skilled in the art need a method to solve the above-mentioned technical problems. Summary of the Invention

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.
[0031] First, the structure of the rolling equipment described in this application will be explained. The rolling equipment includes at least one looper roll, a signal transmitter, and a signal receiver. When the looper roll axially shifts, the optical signal between the signal transmitter and the signal receiver will be blocked by the sleeve of the looper roll, preventing the signal receiver from receiving the optical signal. For example, please refer to... Figure 1 , Figure 1 A simplified structural diagram of a rolling mill according to an embodiment of this application is shown. The rolling mill may include a looper roll 101, a looper roll 102, a looper roll 103, a signal transmitter 104, and a signal receiver 105. The signal transmitter 104 and the signal receiver 105 are installed at appropriate positions on the looper support. The signal transmitter 104 and the signal receiver 105 move up and down together with the looper roll, so that the optical signal path is 1.5 cm away from the looper roll sleeve. When any looper roll shifts, the optical signal will be blocked, and the signal receiver 105 will not be able to receive the optical signal, resulting in a signal reception interruption. The number of times the optical signal reception is interrupted can be used to determine whether the looper roll has shifted.
[0032] In another embodiment of this application, a signal transmitter and a signal receiver may be installed above and below each looper roller, respectively, such as... Figure 2 As shown, the number of interruptions in receiving each optical signal can be used to determine whether each looper roll has shifted, thereby monitoring the rolling equipment.
[0033] In another embodiment of this application, the signal transmitter and the signal receiver can be on the same side, and a light signal reflector can be installed on the other side. After the light signal reaches the reflector, it will be reflected and return to the signal receiver. When any looper roll shifts, the light signal cannot reach the reflector or the light signal reflected from the reflector cannot return to the signal receiver. This can also be used to monitor the rolling equipment.
[0034] Please see Figure 3 , Figure 3A simplified flowchart of a monitoring method for a rolling mill according to an embodiment of this application is shown. The rolling mill includes at least one looper roll, a signal transmitter, and a signal receiver. When the looper roll experiences axial roll shifting, the optical signal between the signal transmitter and the signal receiver is blocked by the sleeve of the looper roll, preventing the signal receiver from receiving the optical signal. The method may include steps S301-S303:
[0035] Step S301: When a position monitoring signal for the looper roller is triggered, the position information of the looper roller is obtained, and the position information is used to characterize the real-time position of the looper roller.
[0036] Step S302: Determine the real-time position of the looper roller based on the position information. If the real-time position is within a preset position range, continuously monitor the optical signal reception status of the signal receiving end.
[0037] Step S303: Based on the number of interruptions in the reception of the optical signal within one monitoring cycle, determine whether the looper roll has experienced axial roll shifting, in order to monitor the rolling equipment.
[0038] In this application, when a position monitoring signal for the looper roll is triggered, the position information of the looper roll is acquired. The position information is used to characterize the real-time position of the looper roll. By setting a signal transmitter and a signal receiver and determining the number of interrupted receptions within a monitoring cycle of the optical signal, it is determined whether the looper roll has experienced axial roll shifting, thereby monitoring the rolling equipment. The equipment requirements are simple and inexpensive, easy to install and maintain, and can simultaneously detect multiple looper rolls. The judgment is accurate and efficient, making it highly practical.
[0039] In this embodiment, data communication also needs to be established to collect and process the operating data of the signal receiving end and the entire rolling equipment, and even the entire rolling production line, to determine the working status of the rolling equipment. The most important step is to determine whether the looper rolls in the rolling equipment are within a preset position range, and whether to start monitoring.
[0040] In this embodiment, if the real-time position is within a preset position range, the optical signal reception status of the signal receiving end can be continuously monitored. Because if any of the looper rolls shifts axially, the bushing will block the optical signal from the signal transmitting end, causing the signal receiving end to be unable to receive the optical signal and resulting in an interruption, the optical signal reception status of the signal receiving end can be continuously monitored, and the number of interruptions within a monitoring cycle of the optical signal can be used to determine whether the looper roll has experienced axial shifting, thereby monitoring the rolling equipment.
[0041] In one embodiment of this application, triggering the position monitoring signal for the looper rolls includes: triggering the position monitoring signal for the looper rolls when the strip head is detected passing through the rolling exit of the rolling mill. In this embodiment, when the strip head passes through the rolling exit of the rolling mill, it proves that the strip has completely passed through all the looper rolls, and the looper rolls begin to work, lifting or lowering to form a loop to adjust the tension of the strip.
[0042] Please see Figure 4 , Figure 4 A simplified flowchart of a monitoring method for a rolling mill according to an embodiment of this application is shown. After obtaining the position information of the looper roll, the method may further include steps S401-S403:
[0043] Step S401: Determine the real-time position of the looper roller based on the position information, and record the first time point and the second time point when the looper roller enters the preset position range and exits the preset position range.
[0044] Step S402: Obtain the optical signal reception status of the signal receiving end between the first time point and the second time point.
[0045] Step S403: Based on the number of interruptions in the reception of the optical signal within one monitoring cycle, determine whether the looper roll has experienced axial roll shifting, so as to monitor the rolling equipment.
[0046] In this embodiment, in addition to continuously monitoring the optical signal reception at the signal receiver as described above, it is also possible to determine whether the looper roller has shifted during a certain time period based on the optical signal reception. Therefore, based on the moment the looper enters the detection range, a second-level photoelectric signal is read. When the photoelectric switch signal receives the reflected signal from the reflector, it is connected (signal 1); when it does not receive the reflected signal, it is not connected (signal 0). The presence or absence of a connection signal is determined by acquiring the photoelectric switch signal when the looper enters the detection position. If there is any connection signal, it indicates that a connection signal has been acquired. Finally, the number of interruptions in optical signal reception within a monitoring cycle is determined, thereby determining whether the looper roller has shifted.
[0047] In one embodiment of this application, the method for determining whether the looper roller has axial roll movement based on the number of interrupted receptions within a monitoring cycle of the optical signal may include: if the number of consecutive interrupted receptions of the optical signal within a monitoring cycle is greater than or equal to a first preset number, then it is determined that the looper roller has axial roll movement.
[0048] In this embodiment, the first step is to determine whether a continuous interruption has occurred. A continuous interruption indicates that the same looper roll has shifted multiple times or that multiple looper rolls have shifted. Furthermore, multiple continuous interruptions within a monitoring cycle further indicate that the working state of the looper roll is very unstable and requires early intervention and control.
[0049] In one embodiment of this application, the method for determining whether the looper roller has axial roll movement based on the number of interrupted receptions of the optical signal within a monitoring cycle may include: if the number of interrupted receptions of the optical signal within a monitoring cycle is greater than or equal to a second preset number, then it is determined that the looper roller has axial roll movement.
[0050] In this embodiment, the number of signal interruptions within a monitoring cycle can be directly determined. If the number is too high, greater than or equal to the preset number, it indicates that the looper roller is still in an unstable working state, and a sway alarm needs to be triggered, requiring early intervention and control.
[0051] To enable those skilled in the art to gain a deeper understanding of this application, the following description will be provided in conjunction with complete embodiments.
[0052] First, refer to Figure 5 , Figure 5 A simplified structural diagram of a rolling mill according to an embodiment of this application is shown. A photoelectric switch 501 (integrated signal transmitter and signal receiver) can be installed at a suitable position on the looper support. In this example, it is installed in the 0.09-0.13 region of the looper's movable position. A reflector 502 is installed on the looper's movable support. The reflector moves up and down with the looper roll, so that the optical signal path is 1.5 cm away from the work roll bushing.
[0053] The specific process can be as follows:
[0054] Step 1: Establish data communication, establish data, establish PLC communication, and collect loop position data in real time.
[0055] Step 2: Determine if the looper is at the detection position. Read the real-time data of the looper and the production line operation data. Determine if the position data is between 0.09 and 0.13. When the production line is running, record the entry time and exit time of the looper within this range.
[0056] Step 3: Acquire the photoelectric development signal. Based on the moment the looper enters the detection range, read the photoelectric signal at the second level. When the photoelectric switch signal receives the reflected signal from the reflector, it is connected, and the signal is 1; when it does not receive the reflected signal from the reflector, it is not connected, and the signal is 0.
[0057] Step four: Determine if there is a connection signal. Obtain the photoelectric switch signal when the looper enters the detection position. If there is any connection signal, it means that a connection signal has been obtained.
[0058] Step 5: Determine a periodic warning. If there is no connection signal within a detection period, it indicates that a warning is issued for that detection period.
[0059] Step 6: Record each periodic warning and determine if there are two consecutive warnings. If so, trigger the scrambling alarm.
[0060] The embodiments of the device provided in this application will now be described in conjunction with the accompanying drawings.
[0061] Please see Figure 6 , Figure 6 A block diagram of a rolling mill monitoring device according to an embodiment of this application is shown. The rolling mill includes at least one looper roll, a signal transmitter, and a signal receiver. When the looper roll undergoes axial roll shifting, the optical signal between the signal transmitter and the signal receiver is blocked by the sleeve of the looper roll, causing the signal receiver to be unable to receive the optical signal. The device 600 may include: an acquisition unit 601, a detection unit 602, and a judgment unit 603.
[0062] The acquisition unit 601 can be used to acquire the position information of the looper roll when a position monitoring signal for the looper roll is triggered. The position information is used to characterize the real-time position of the looper roll. The detection unit 602 can be used to determine the real-time position of the looper roll based on the position information. If the real-time position is within a preset position range, the optical signal reception status of the signal receiving end is detected. The judgment unit 603 can be used to determine whether the looper roll has experienced axial roll movement based on the number of interrupted receptions within a monitoring cycle of the optical signal, so as to monitor the rolling equipment.
