Description

Technical Field

[0001] This application relates to the field of metallurgical technology, and in particular, to a control method, device, medium, and equipment for a pyrometer in a hot rolling production line. Background Art

[0002] Pyrometers for measuring the temperature of strip steel are installed at positions such as the entrance of the roughing mill, the exit of the roughing mill, the entrance of the finishing mill, and the exit of the finishing mill in the hot rolling production line. The detected temperature values enter the control system for load distribution calculation of the rolling mill. In the actual production process, due to the influence of the working conditions in each area, the detection of the pyrometer is blocked and interfered by scale, steam, etc. The detected strip steel temperature value is lower than the actual temperature value of the strip steel, resulting in the control system considering the strip steel temperature to be low, abnormal calculation of the rolling mill load distribution, mismatch in the second flow rate control of the strip steel, and reduction in rolling stability, which is extremely likely to cause a steel piling accident.

[0021] Example embodiments will now be described more fully with reference to the accompanying drawings. However, the example embodiments can be implemented in various forms and should not be construed as limited to the examples set forth herein; rather, these embodiments are provided so that this application will be more complete and comprehensive, and will fully convey the concept of the example embodiments to those skilled in the art.

[0022] In addition, the described features, structures, or characteristics may 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 the embodiments of this application. However, those skilled in the art will realize that the technical solutions of this application can be practiced without one or more of the specific details, or other methods, components, devices, steps, etc. may be employed. In other cases, well-known methods, devices, implementations, or operations are not shown or described in detail to avoid obscuring aspects of this application.

[0023] The block diagrams shown in the drawings are merely functional entities and do not necessarily correspond to physically independent entities. That is, these functional entities can be implemented in software form, or in one or more hardware modules or integrated circuits, or in different networks and / or processor devices and / or microcontroller devices.

[0024] The flowcharts shown in the drawings are merely illustrative and do not necessarily include all the content and operations / steps, nor do they necessarily have to be executed in the order described. For example, some operations / steps can be decomposed, while some operations / steps can be combined or partially combined, so the actual execution order may change according to the actual situation.

[0025] The implementation details of the technical solutions of the embodiments of this application are elaborated in detail below:

[0026] When a control function start instruction is received, the real-time temperature detection value of the pyrometer is collected once every PLC scan cycle time; n adjacent real-time temperature detection values of the pyrometer are selected for comparison, and the maximum value among them is taken as the candidate temperature detection value of the pyrometer; the candidate temperature detection value of the pyrometer is collected once every predetermined time as the target temperature detection value, and N adjacent target temperature detection values are selected for comparison. When the Nth target temperature detection value is greater than or equal to the (N - 1)th target temperature detection value, the Nth target temperature detection value is output as the target value of the pyrometer; when the Nth target temperature detection value is less than the (N - 1)th target temperature detection value, the average value of the Nth target temperature detection value and the (N - 1)th target temperature detection value is taken as the target value of the pyrometer.

[0027] In view of the problems that the pyrometer for measuring the strip temperature in the hot rolling production line detects too low temperature detection values due to the interference of scale, steam and other factors, and inputs them into the control system, resulting in abnormal calculation of the mill load distribution, etc., this method selects the maximum value of the pyrometer detection values within a predetermined interval time as the target value of the pyrometer and inputs it into the control system. At the same time, the relatively low temperature detection values are weakened, avoiding the control system from using the detection data with a large deviation from the actual temperature of the strip for the mill load distribution calculation, and improving the rolling stability.

[0028] To enable those skilled in the art to better understand this application, the following will be combined with Figure 1 to briefly describe this application.

[0029] According to some embodiments, this application provides a control method for a pyrometer in a hot rolling production line, and the method includes:

[0030] Step 101, obtain a target temperature detection value every preset time interval, and obtain at least two target temperature detection values;

[0031] Step 102, compare two target temperature detection values with adjacent acquisition times among at least two target temperature detection values, and among the two adjacent times, the first acquisition time is earlier than the second acquisition time;

[0032] Step 103, if the target temperature detection value at the second acquisition time < the target temperature detection value at the first acquisition time, then take the average value of the target temperature detection value at the second acquisition time and the target temperature detection value at the first acquisition time as the target value.

[0033] Based on the above embodiments, in step 101, the preset time can be set to different times from 10 seconds to 30 seconds according to actual needs. Obtain a target temperature detection value every preset time interval, and obtain two or more target temperature detection values.

[0034] In step 102, among the obtained target temperature detection values, compare two target temperature detection values with adjacent acquisition times. Among them, if 6 target temperature detection values are obtained, and their acquisition times are sorted from earliest to latest as the 1st, 2nd... 5th, 6th, then compare the 1st and the 2nd, compare the 3rd and the 4th, and compare the 5th and the 6th.

[0035] In step 103, if the 6th target temperature detection value is less than the 5th target temperature detection value, then take the average value of the 6th target temperature detection value and the 5th target temperature detection value as the target value. In some embodiments, take the target value as the accurate value of the temperature detection, output it to the control system for the mill load distribution calculation, and when the temperature value is required for the mill load distribution calculation, use the target value for the calculation.

[0036] According to some embodiments, in the case where the target temperature detection value at the second acquisition time < the target temperature detection value at the first acquisition time, when taking the average value of the target temperature detection value at the second acquisition time and the target temperature detection value at the first acquisition time as the target value, the method further includes:

[0037] In the case where the target temperature detection value at the second acquisition time ≥ the target temperature detection value at the first acquisition time, take the target temperature detection value at the second acquisition time as the target value.

[0038] Based on the above embodiments, if the 6th target temperature detection value is greater than or equal to the 5th target temperature detection value, then take the 6th target temperature detection value as the target value. In some embodiments, due to the influence of the working conditions of each region, the detection of the pyrometer is blocked and interfered by scale, steam, etc., and the detected strip temperature value is lower than the actual temperature value of the strip, resulting in the control system thinking that the strip temperature is too low. And the highest value detected by the pyrometer is generally an accurate value. Therefore, if the 6th target temperature detection value, which is detected at a later time, is greater than or equal to the 5th target temperature detection value, take the 6th target temperature detection value as the accurate value of the temperature detection, that is, the target value.

[0039] According to some embodiments, before step 101, where a target temperature detection value is obtained every preset time interval and at least two target temperature detection values are obtained, the method further includes:

[0040] Step 91, collect real-time temperature detection values once every scan cycle;

[0041] Step 92, obtain all the real-time temperature detection values within a preset time period as a candidate set, obtain multiple candidate sets, select the maximum value from the candidate sets as the candidate temperature detection value, and obtain the target temperature detection value from multiple candidate temperature detection values.

[0042] Based on the above embodiments, in step 91, the scan cycle is the scan cycle of the PLC, that is, the real-time temperature detection value of the pyrometer is collected once every time period of the PLC scan cycle. The PLC scan cycle time can be different times from 1 millisecond to 100 milliseconds according to the scan speed of the PLC system or the length of the control program.

[0043] In step 92, select a preset time period, obtain all the real-time temperature detection values within the preset time period, form all the real-time temperature detection values into a candidate set, obtain candidate sets for multiple time periods, and select the maximum value from each candidate set as the candidate temperature detection value. Then enter step 101, obtain a candidate temperature detection value every preset time interval, and take the obtained candidate temperature detection value as the target temperature detection value.

[0044] According to some embodiments, the preset time period range is set to 1000 milliseconds, and the number of all real-time temperature detection values within the preset time period = preset time period ÷ scan cycle.

[0045] Based on the above embodiments, the preset time period is set to 1000 milliseconds, and all real-time temperature detection values are checked within 1000 milliseconds. The number of all real-time temperature detection values = preset time period ÷ scan cycle.

[0046] According to some embodiments, the method includes:

[0047] The pyrometers are respectively installed at the entrance of the rough rolling mill, the exit of the rough rolling mill, the entrance of the finishing mill, and the exit of the finishing mill.

[0048] Based on the above embodiments, it can be used to detect the temperature of the rolled strip at different positions in the mill area. The number of pyrometers installed at positions such as the entrance of the rough rolling mill, the exit of the rough rolling mill, the entrance of the finishing mill, and the exit of the finishing mill can be 1, 2, or multiple. For positions where 2 or more pyrometers are installed, the target temperature detection value of a certain one of the pyrometers can be selected alone, or the average value of the target temperature detection values of 2 or more pyrometers can be calculated as the target temperature detection value at this position. The target temperature detection values of the pyrometers at the entrance and exit of the rough rolling mill are used for the load distribution calculation of the rough rolling mill; the target temperature detection values of the pyrometers at the entrance and exit of the finishing mill are used for the load distribution calculation of the finishing mill.

[0049] The following introduces the device embodiments of the present application, which can be used to execute the control method in the above embodiments of the present application.

[0050] Figure 2 The schematic diagram of the control device 200 of the pyrometer in a hot rolling production line according to an embodiment of the present application is shown. The control device 200 of the pyrometer in the hot rolling production line includes:

[0051] An acquisition module 201, configured to acquire a target temperature detection value once every preset time, and acquire at least two target temperature detection values;

[0052] A comparison module 202, configured to compare two target temperature detection values with adjacent acquisition times among at least two target temperature detection values, and among the two adjacent times, the first acquisition time is earlier than the second acquisition time;

[0053] A correction module 203, configured to, if the target temperature detection value at the second acquisition time < the target temperature detection value at the first acquisition time, then use the average value of the target temperature detection value at the second acquisition time and the target temperature detection value at the first acquisition time as the target value.

[0054] Based on the above embodiments, in the acquisition module 201, the preset time can be set to different times from 10 seconds to 30 seconds according to actual requirements. The target temperature detection value is acquired once every preset time interval, and two or more target temperature detection values are acquired.

[0055] In the comparison module 202, among the acquired target temperature detection values, two target temperature detection values with adjacent acquisition times are compared. Among them, if 6 target temperature detection values are acquired, and their acquisition times are sorted from earliest to latest as the 1st, 2nd... 5th, and 6th, then the 1st and 2nd are compared, the 3rd and 4th are compared, and the 5th and 6th are compared.

[0056] In the correction module 203, if the 6th target temperature detection value is less than the 5th target temperature detection value, then the average value of the 6th target temperature detection value and the 5th target temperature detection value is used as the target value. In some embodiments, the target value is used as the accurate value of temperature detection and output to the control system for rolling mill load distribution calculation. When a temperature value is required for rolling mill load distribution calculation, the target value is used for calculation.

[0057] According to some embodiments, the correction module 203 further includes:

[0058] If the target temperature detection value at the second acquisition time ≥ the target temperature detection value at the first acquisition time, then the target temperature detection value at the second acquisition time is used as the target value.

[0059] Based on the above embodiments, if the 6th target temperature detection value is greater than or equal to the 5th target temperature detection value, then the 6th target temperature detection value is used as the target value. In some embodiments, due to the influence of the working conditions in each area, the detection of the pyrometer is blocked and interfered by scale, steam, etc., and the detected strip temperature value is lower than the actual temperature value of the strip, resulting in the control system thinking that the strip temperature is low. And the highest value detected by the pyrometer is generally the accurate value. Therefore, if the 6th target temperature detection value with a later detection time is greater than or equal to the 5th target temperature detection value, the 6th target temperature detection value is used as the accurate value of temperature detection, that is, the target value.

[0060] According to some embodiments, the device further includes:

[0061] An acquisition module, configured to acquire real-time temperature detection values once every scan period;

[0062] A candidate selection module, configured to acquire all real-time temperature detection values within a preset time period as a candidate set, acquire multiple candidate sets with adjacent times, select the maximum value from the candidate set as the candidate temperature detection value, and the target temperature detection value is acquired from the candidate set.

[0063] Based on the above embodiments, in the acquisition module, the scanning period is the scanning period of the PLC, that is, the real-time temperature detection value of the pyrometer is acquired once every time the scanning period of the PLC elapses. The PLC scanning period can be different times from 1 millisecond to 100 milliseconds according to the scanning speed of the PLC system or the length of the control program.

[0064] In the candidate module, a preset time period is selected, all the real-time temperature detection values within the preset time period are obtained, and all the real-time temperature detection values are formed into a candidate set. Candidate sets for multiple time periods are obtained, and the maximum value is selected from each candidate set as the candidate temperature detection value. Then, it enters the acquisition module 201, and the candidate temperature detection value is obtained once every preset time interval, and the obtained candidate temperature detection value is used as the target temperature detection value.
