Detailed Description
The technical solutions in the embodiments of the present application will be described below with reference to the drawings in the embodiments of the present application.
At present, some steel production enterprises mainly produce industrial wires, have various product types and small order quantity, and the processing technology adopted by downstream users may be different. Based on this, these enterprises can design different rolling processes according to the product application and the individual requirements of downstream users, and even if the same steel grade with the same specification can adopt different rolling and cooling control process systems. In addition, when a new variety is developed or an original process system is optimized, there is also a need for frequent adjustment of cooling control process parameters in a small-lot trial production process (the cooling control process parameters are a kind of rolling process parameters).
In the existing processing mode, each variety switching in the production process requires an operator to inquire parameters from a factory command level management system specially used for storing a process system and a process production contract, and after cold control process parameters required by the next rolled variety to be rolled are inquired, picking and copying and transcription are carried out so as to transcribe the inquired data to an electric automatic control system of steel rolling basic equipment. In practical applications, however, the controlled cooling process of a high-speed wire rod production line involves tens of parameters related to the air cooling line. In the picking and transcribing processes, workers are required to check the whole set of cooling control process parameters, the time consumption is long, and the risk of wrong stored information entry is high. Generally, in order to reduce the risk of data logging errors, workers need to be assigned to perform secondary confirmation on the data accuracy of parameter extraction, and the whole processing process is long in time consumption and high in labor cost.
In order to reduce the operation intensity of workers, improve the processing efficiency of the switching process of the cooling control process, improve the production operation efficiency and improve the accuracy of the execution of the process system, the inventor provides the following embodiments for improvement.
Referring to fig. 1, fig. 1 is a schematic diagram of a wire production control system according to an embodiment of the present disclosure.
As shown in fig. 1, the wire production control system includes a planning system 100, a monitoring system 200, and an execution system 300. The wire rod production control system can be used for executing the rolling process parameter processing method provided by the embodiment of the application.
Planning system 100 is communicatively coupled to monitoring system 200, and monitoring system 200 is communicatively coupled to execution system 300.
In the embodiment of the present application, the planning system 100 may be represented as a three-stage system (L3), the monitoring system 200 may be represented as a two-stage system (L2), and the execution system 300 may be represented as a one-stage system (L1). And the three-level system L3 is used as a production management layer and is used for issuing a production plan and collecting production actual results. In some application scenarios, an MES System (manufacturing execution System) may be used as the planning System in the embodiment of the present application. The secondary system (L2) is mainly used for realizing the tracking and monitoring of the production process, and is used for executing the plan issued by the tertiary system (L3), tracking the production process information uploaded by the primary system (L1), collecting the production actual results and uploading the production actual results to the tertiary system (L3). The primary system (L1) can be a general term of an electric automatic control system of the steel rolling basic equipment. The planning system 100 may include a region manager, which is divided according to production and manufacturing units. The monitoring system 200 may include a host computer capable of performing data operations, and the execution system 300 may include some basic automated processing devices, for example, some meters, detection devices, driving devices, and the like.
In the embodiment of the present application, the execution system 300 and the monitoring system 200 perform data interaction based on an object connection and embedding for Process Control (OLE for Process Control, OPC for short) standard. The monitoring system 200 may read various meter data and various monitoring signals of the execution system 300 in real time according to the OPC. For example, the monitoring system 200 may read data based on readings from some of the temperature sensors, thermal detection signals, proximity switch signals, motor speed/torque, electro-optical signals, etc. in the OPC execution system 300. The monitoring system 200 can perform logic judgment according to the data, so as to determine the position of the flow path of the currently processed product, and thus realize the tracking of the production process.
In the embodiment of the present application, the planning system 100 may be configured to issue a rolling plan to the monitoring system 200, where the rolling plan is used to instruct the execution system 300 to control the wire rod production line to perform wire rod processing, and the rolling plan includes a rolling lot number and a cooling control process parameter matched with the rolling lot number. The monitoring system 200 may be configured to monitor the production process information collected by the execution system 300, and determine the production progress of the wire rod of the current rolling batch according to the production process information. The monitoring system 200 may also be configured to send the cooling control process parameters of the next rolling batch to the execution system 300 when it is determined that the last billet of the current rolling batch is discharged or when it is determined that the last billet of the current rolling batch is delivered to the laying head after being discharged. The execution system 300 can be used for updating the parameters of the air cooling line on the wire production line according to the cooling control process parameters of the next rolling batch when the set parameter switching conditions are met.
By the wire production control system, the manual query and transcription processing processes can be reduced, the cooling control process parameters are brought into the rolling plan by matching and associating the cooling control process parameters with the rolling batches, and the cooling control process parameters are issued to the monitoring system 200 together when the planning system 100 issues the rolling plan to the monitoring system 200 so as to be temporarily stored by the monitoring system 200. The monitoring system 200 forwards parameters according to the monitored and determined wire rod production progress, and the execution system 300 changes the air cooling line according to the cooling control process parameters of the next rolling batch when the set parameter switching conditions are met, so that the air cooling line has the production conditions for producing the wire rods of the next rolling batch. Thereby performing controlled cooling process switching, variety switching and production plan switching. The cold control process switching treatment process realized by the whole system can reduce manual operation, improve the switching treatment efficiency and reduce the treatment time.
Optionally, after the execution system 300 receives the cooling control process parameters of the next rolling batch forwarded by the monitoring system 200, the execution system can be used to perform parameter adjustment on the air-cooling line on the wire production line in two cooling control process change execution manners.
One of the two change execution modes is as follows: after the monitoring system 200 sends the cooling control process parameters of the next rolling batch to the execution system 300, the execution system 300 writes the cooling control process parameters of the next rolling batch into the parameter setting column and displays the execution confirmation button on the operation interface. The execution system 300 responds to the confirmation execution operation of the confirmation execution button, determines that the current time meets the set parameter switching condition, and updates the parameters of the air cooling line on the wire production line according to the cooling control process parameters in the parameter setting column. Therefore, the automatic input of the cooling control process parameters in the execution system 300 can be realized, and when the execution button is confirmed by manual triggering, the cooling control process parameters automatically input to the parameter setting column begin to take effect, so that the air cooling line on the wire rod production line is controlled to operate according to the new cooling control process parameters. This implementation still need not the user and types the parameter by oneself, avoids the wrong risk of record that the process of copying appears easily, only needs the user to carry out the node according to the wire rod production progress of reality and confirms, can carry out the batch change to the accuse cold process parameter of automatic entering at suitable opportunity.
In order to further reduce the manual confirmation link, the other of the two change execution modes is as follows: the execution system 300 calculates the predicted passing time of the rolled material passing through each section of air-cooled roller way based on the roller way running speed of each section of air-cooled roller way on the air-cooled line and the physical length of each section of air-cooled roller way. The execution system 300 performs delay waiting based on the predicted passing time of the rolled material through each section of air-cooled roller way, and when the delay waiting is finished, parameter updating is performed on each section of air-cooled roller way on the air-cooled line according to the cooling control process parameters of the next rolling batch. According to the implementation mode, due to the fact that the rolling material is subjected to delay waiting through the predicted passing time of each section of air-cooled roller way, parameter updating is carried out on each section of air-cooled roller way after the delay waiting, the execution system 300 can be used for automatically realizing step-by-step delay updating based on the parameters forwarded by the monitoring system 200, manual confirmation is not needed in the parameter switching process, when the system automatically carries out step-by-step parameter adjustment, the first steel material of the next batch can be discharged (the steel material is required to be processed by a rolling mill and a wire laying machine in sequence and then is sent to the air-cooled roller way after being discharged), and the last steel material of the current batch is not required to be completely discharged by the air-cooled wire line after. The implementation mode can reduce the time for switching rolling plans and effectively improve the working efficiency.
In other embodiments, the wire production control system may further include a higher-level four-stage system (L4), and the four-stage system (L4) may perform data interaction with the three-stage system (L3). The level four System (L4) is generally used for making Decision content at the strategic and administrative levels of the Enterprise, and the level four System (L4) may include a Decision Support System (DSS) and an Enterprise Resource Planning (ERP) System.
In one example, the execution system 300 is used for issuing operation instructions and control instructions to a high-speed wire production line for producing industrial wires, and collecting production process information of the high-speed wire production line, including equipment operation data, material processing states, and the like. In some application scenarios, a wire rod with a rolling speed of 80 m/s or more is called a high-speed wire rod (abbreviated as a high-speed wire rod).
It will be appreciated that the configuration shown in fig. 1 is merely illustrative, and in practical applications, the wire production control system may have a different architecture than that shown in fig. 1 or have more subsystems, and may have more functions.
Based on the same inventive concept, the embodiment of the application also provides a rolling process parameter processing method, and the method can be applied to the wire production control system provided by the embodiment of the application. The wire production control system comprises a planning system, a monitoring system and an execution system.
Referring to fig. 2, fig. 2 is a flowchart of a rolling process parameter processing method according to an embodiment of the present application.
As shown in FIG. 2, the method includes steps S21-S27.
S21: and the planning system issues a rolling plan to the monitoring system.
The rolling plan is used for indicating the execution system to control the wire rod production line to process the wire rod, and the rolling plan comprises rolling batch numbers and cooling control technological parameters matched with the rolling batch numbers.
The rolling plan may further include: smelting number, steel type, specification, count, single count weight and the like. When the planning system issues the rolling plan to the monitoring system, the information of the smelting number, the steel grade, the specification, the count, the single-branch weight and the like and the cold control process parameters included in the rolling plan can be sent to the monitoring system together.
The equipment for producing the wire rods on the wire rod production line can comprise a heating furnace, a rolling mill unit and a wire laying head, and flying shears are arranged among all units of the rolling mill unit. The wire rod production line processes the billets of each rolling batch to be processed according to a first-in first-out processing principle. A rolling batch of billets has a rolling batch number. Each batch comprises one or more steel billets.
S22: based on S21, the monitoring system receives the rolling plan issued by the planning system.
After the monitoring system receives the rolling plan sent by the planning system, the received rolling plan can be temporarily stored.
S23: the monitoring system monitors the production process information acquired by the execution system and determines the production progress of the wire rods of the current rolling batch according to the production process information.
In relation to S23, the monitoring system may obtain data from the execution system in real time to monitor the wire production line in real time, so as to obtain the production process information of the current wire production line in the processing production process. The monitoring system can analyze, identify and process the production process information so as to determine the wire rod production progress of the steel billets of the current rolling batch on the wire rod production line, for example, the wire rod production progress can be known how many steel billets are respectively processed by a heating furnace, each unit of a rolling mill unit and a laying head on the wire rod production line, and the degree of each steel billet processed (for example, whether rough rolling, finish rolling and the like are finished) can be known.
In one example, in order to facilitate describing the wire production progress, in a group of billets corresponding to each rolling batch, a serial number is set for each billet entering the heating furnace, and each billet of each rolling batch can be described in a mode of rolling batch number + serial number.
S24: and when the last steel billet of the current rolling batch is determined to be discharged from the furnace or the last steel billet of the current rolling batch is determined to be sent to the laying head after being discharged from the furnace, the monitoring system sends the cooling control process parameters of the next rolling batch to the execution system.
Because the planned total number of production of each rolling batch number is determined, the data of each time of furnace entering/discharging and wire feeding/wire discharging of the laying head can be monitored and recorded, whether the steel billet currently discharged from the furnace or sent to the laying head is the last one of the rolling batch can be determined according to the monitored production process information, and if the steel billet is determined to be the last one, the monitoring system sends the cold control process parameters corresponding to the next rolling batch to the execution system. That is, when it is determined that the last billet of the current rolling batch is discharged, or when it is determined that the last billet of the current rolling batch is delivered to the laying head after being discharged, it is determined that the monitoring system satisfies the parameter forwarding condition. At this time, the monitoring system can forward the cooling control process parameters of the next rolling batch to the execution system, so that the execution system can receive the cooling control process parameters of the next rolling batch.
Optionally, in order to avoid that the monitoring system fails to forward the parameters due to network instability and other problems in the process of sending the cooling control process parameters to the execution system, the monitoring system may repeatedly send an update data packet to the execution system in a set period, where the update data packet includes the cooling control process parameters of the next rolling batch. If the execution system receives the cooling control process parameters with the same content, repeated actions are not needed (repeated updating is not needed, and coverage replacement can be conducted by using the same parameter content). The execution system may determine whether there are new cooling control process parameters by identifying the contents of a specified byte in the update package or parsing the cooling control process parameters in the update package.
In one example, the monitoring system may send a text message to transmit the update packet every two seconds.
S25: based on S24, the execution system receives the controlled cooling process parameters of the next rolling batch from the monitoring system.
After the execution system receives the cooling control process parameters of the next rolling batch, S26 is executed.
S26: the execution system judges whether the set parameter switching condition is met currently.
As an implementation manner, when receiving the confirmation execution operation initiated manually, it may be considered that the set parameter switching condition is currently satisfied.
As another implementation manner, the execution system may perform delay waiting based on a steel throwing signal of the laying head, and the set parameter switching condition is considered to be satisfied at the time when the delay waiting time is over.
S27: based on S26, when the set parameter switching condition is determined to be met, the execution system updates the parameters of the air cooling line on the wire production line according to the cooling control process parameters of the next rolling batch.
When the parameter switching condition is not met, the air cooling line runs according to the original cooling control technological parameters during working.
The wire rod production line comprises a plurality of sections of air-cooled roller ways on the air-cooled line, and the execution system can update the parameters of each section of air-cooled roller way on the air-cooled line according to the cooling control process parameters of the next rolling batch. Assuming that there are 10 segments of air-cooled roller ways on one air-cooled line, if the cooling control process parameters of the next rolling batch are changed for part of the 10 segments of air-cooled roller ways, the parameters of the part of the roller ways which need to be changed are updated when S27 is executed. The roller way after parameter change will operate with the new controlled cooling process parameters.
In a processing and production scene, after a group of billets to be processed enter a heating furnace, the heating furnace continuously heats each billet, and the discharged billets are sent to a rolling mill unit for rolling according to a first-in first-out principle. The discharged steel billets are rolled by a rough rolling unit, a medium rolling unit and a finishing rolling unit in sequence, then are sent to a wire laying head, and are turned into rings by the wire laying head and fall to an air cooling line for controlled cooling treatment. Each section of air-cooled roller way on the air-cooled line is provided with a group of roller way driving motors, a heat-insulating cover and a fan. And when the execution system determines that the set parameter switching condition is met, parameter change is carried out on at least one of the roller way driving motor, the heat preservation cover and the air-cooling control fan (fan for short) of each section of air-cooling roller way according to the cooling control process parameter of the next rolling batch from the monitoring system.
By the method of S21-S27, the manual query and transcription processing processes can be reduced, the cooling control process parameters are matched and associated with the rolling batches, the cooling control process parameters are included in the rolling plan, and the cooling control process parameters are issued to the monitoring system when the rolling plan is issued to the monitoring system by the planning system for temporary storage of the monitoring system. The monitoring system determines the current wire production progress according to the actually monitored production process information of the wire production line, and when the wire production progress is monitored to meet the condition that the last steel billet is discharged from a furnace or sent to a laying head, the cooling control process parameters of the next rolling batch are sent to the execution system of the base layer, so that the execution system can change the air cooling line according to the cooling control process parameters of the next rolling batch when meeting the set parameter switching condition, and the air cooling line can be provided with the production conditions for producing the wire of the next rolling batch in a short time, thereby carrying out process parameter switching, variety switching and production plan switching. The whole switching processing process reduces manual operation, can improve the switching processing efficiency and reduce the processing time.
Optionally, the cooling control process parameters in the method include: at least one of motor control parameters of each section of air-cooled roller way on the air-cooled line, protection cover control parameters of each section of air-cooled roller way on the air-cooled line, and fan control parameters of each section of air-cooled roller way on the air-cooled line.
The execution system can adjust the rotating speed of a roller way driving motor of the air-cooled roller way through motor control parameters, so that the running speed of the air-cooled roller way can be changed.
The execution system can switch the opening and closing states of the heat-insulating cover of the air-cooled roller way through the control parameters of the protective cover.
The execution system can adjust the fan frequency of the air cooling roller way through fan control parameters.
Through the implementation mode, the cooling control process adjustment can be performed on various types of process parameters, flexible change is realized, the method is applicable to complex production scenes of air cooling lines, frequent and diversified parameter switching can be performed, and efficient switching can be performed in small-batch and various production scenes. In one example, the above embodiment may switch parameters of forty or more parameters in total, such as the speed of each roller way of the air cooling line, the fan operating frequency, and the on/off state setting parameter of the heat-insulating cover, which are involved in the cooling control process.
Optionally, as shown in fig. 3, when the execution system receives the cooling control process parameters of the next rolling batch from the monitoring system, automatic parameter entry may be implemented based on the sub-step S261, and parameter switching may be implemented based on the sub-step S271.
S261: and the execution system writes the cooling control process parameters of the next rolling batch into the parameter setting column and displays an execution confirmation button on the operation interface.
S271: and responding to the confirmation execution operation of the confirmation execution button, determining that the current time meets the set parameter switching condition, and updating the parameters of the air cooling line on the wire production line by the execution system according to the cooling control process parameters in the parameter setting column.
The user can observe the material processing condition on the air cooling line through the monitoring camera, and when the last steel of the current rolling batch on the air cooling line is confirmed to completely pass through the air cooling roller way, the user can initiate the confirmation execution operation on the confirmation execution button.
Through the implementation manners of S261 and S271, when the execution system detects that the confirmation execution button is triggered (for example, when the execution system is clicked), the parameter of the air-cooling line can be updated based on the motor control parameter, the protection cover control parameter, or the fan control parameter written in the parameter setting field, so that batch change of the air-cooling line can be realized, adjustment of the cooling control parameter of the next batch can be completed, and the air-cooling line after parameter change has a wire production condition for producing the wire of the next rolling batch. And when the execution system updates the parameters of the air cooling line, allowing the first billet in the next rolling batch to be discharged. The whole processing process can reduce the processing operation steps of operators, can reduce the labor cost to a certain extent, does not need manual parameter copying, can automatically input the parameters to be changed into the parameter setting column, reduces the risk of manual error recording, and improves the production stability.
Alternatively, as shown in fig. 4, after the execution system receives the cooling control process parameters of the next rolling batch from the monitoring system, the cooling control process parameters of the next rolling batch may be updated in a step-by-step delayed manner based on the sub-steps S262 and S272.
S262: and the execution system calculates and obtains the predicted passing time of the rolled material passing through each section of air-cooled roller way based on the roller way running speed of each section of air-cooled roller way on the air-cooled line and the physical length of each section of air-cooled roller way.
If the air cooling line has a section a of air cooling roller ways, the execution system can calculate the predicted passing time corresponding to each section of roller ways in the section a of air cooling roller ways according to the physical length and the current running speed of each section of roller ways in the section a of air cooling roller ways, and a predicted passing times are obtained.
S272: and the execution system carries out delay waiting on the basis of the predicted passing time of the rolled material through each section of air-cooled roller way, and when the delay waiting is finished, parameter updating is respectively carried out on each section of air-cooled roller way on the air-cooled line according to the controlled cooling process parameters of the next rolling batch.
Because the sequence of each section of air-cooled roller way on the air-cooled line is fixed, the total passing time corresponding to at least one section of air-cooled roller way can be calculated according to the predicted passing time corresponding to each section of roller way. The aggregate transit time is a sum of the at least one expected transit time. The total duration of the delay wait is greater than or equal to the total transit time.
The execution system can determine which roller way parameters need to be changed according to the controlled cooling process parameters of the next rolling batch, and updates the roller ways in sequence based on the positions of the roller ways which need to be changed. The execution system can take the roller way which needs to be changed each time as a target roller way, and changes parameters of at least one of a roller way driving motor, a heat preservation cover and a fan of the target roller way. According to the difference possibly existing in the actual rolling batches, the target roller way can be any section of air-cooled roller way on the air-cooled line.
As an implementation manner of S272, the execution system may use the time when the tail of the last rolled material of the current rolling batch passes through the laying head as an initial time, and perform the delay waiting according to the total passing time required by the rolled material from entering the first air-cooled roller way to passing through the target roller way. And when the delay waiting corresponding to the total passing time is finished, the execution system updates the parameters of the target roller way according to the cooling control process parameters of the next rolling batch so that the target roller way works according to the cooling control process parameters of the next rolling batch.
Wherein, whether the last rolled material of the current rolling batch completely passes through the laying head can be determined according to the steel biting signal of the laying head and the steel throwing signal of the laying head. When the tail of the last rolled material of the current rolling batch passes through the laying head, the corresponding steel throwing signal of the laying head can be received, and the moment when the tail of the last rolled material of the current rolling batch passes through the laying head is taken as the initial time. Optionally, the monitoring system may send an indication signal to the execution system at this time to indicate that the time node at this time may be the initial time of the delay waiting process.
Considering that materials (rolled materials) with different serial numbers pass through the same air-cooling roller bed at the same speed when being conveyed to the same air-cooling roller bed under the condition of not changing the working state of the laying head, the realization mode of estimating the total communication time is provided: assuming that the target roller way is the nth section of air-cooled roller way on the air-cooled line, the total passing time of the rolled material from the first air-cooled roller way to the target roller way is calculated by a first expression.
The first expression includes:
Figure BDA0002594359450000201
wherein T represents the total passing time from the time when the rolled material enters the first air-cooled roller way to the time when the rolled material passes through the nth section of air-cooled roller way, and TiRepresents the predicted passing time s required by the rolled material to pass through the section i of the air-cooled roller table on the air-cooled lineiRepresents the physical length, v, of the section i of the air-cooled roller wayiAnd (4) representing the current running speed of the section i air-cooled roller way.
Based on the step-by-step and delayed updating principleThe execution system can take the moment when the tail of the rolled material passes through the laying head as the starting time, carry out delay waiting according to the calculated total passing time, and when the delay waiting time reaches t1And allowing the execution system to execute parameter change of the 1 st segment air-cooled roller way on the air-cooled line according to the new controlled cooling process parameters (if the controlled cooling process parameters of the next rolling batch on the 1 st segment roller way are the same as those of the current batch, the parameters of the 1 st segment roller way do not need to be changed). Similarly, the waiting time reaches t1+2Allowing the execution system to execute parameter change of the 2 nd section air-cooled roller way on the air-cooled line according to new controlled cooling process parameters, and waiting for time t1+2+3And allowing the execution system to execute parameter change of the 3 rd section air-cooled roller way on the air-cooled line according to the new controlled cooling process parameters. Waiting for a time of t1+2+3+4And allowing the execution system to execute parameter change of the 4 th section of air-cooled roller way on the air-cooled line according to the new controlled cooling process parameters. The changed parameters of each section of air-cooled roller way can be any one or more of motor control parameters, protection cover control parameters and fan control parameters.
Through the implementation manners of S262 and S272, adjustment of the cooling control process parameters can be completed in time according to the actual progress without waiting for the rolled material to completely pass through the whole cooling air line, for example, for the total 15 segments of cooling air lines of the cooling air roller ways, if the cooling control process parameters of the next rolling batch are used for adjusting the 3 rd, 4 th and 6 th segments of roller ways in the 15 segments of roller ways, even if the last rolled material of the current rolling batch does not completely pass through the 15 segments of roller ways, as long as the condition that the execution system is allowed to perform parameter change on the 3 rd, 4 th and 6 th segments of roller ways is detected on the time condition, the parameter change can be performed on the 3 rd, 4 th and 6 th segments of roller ways according to the cooling control process parameters related to the 3 rd, 4 th and 6 th segments of roller ways in the next rolling batch.
And after the parameters of one section of roller way are changed, discharging the first billet of the next rolling batch. In order to avoid the situation that the speed of the adjusted roller way is several times faster than that of the previous batch after the speed of the roller way of the next rolling batch is adjusted, in the actual production, a series of production contracts can be sequenced according to the running speed of the air-cooled roller ways, the rolling batch corresponding to the contract with the higher running speed of the air-cooled roller ways is preferentially produced, and therefore the phenomenon that the air-cooled roller ways with the adjusted parameters catch up and exceed other unadjusted air-cooled roller ways in the running speed is avoided.
In one example, in order to avoid the air-cooled roller ways after the parameter adjustment from overtaking and being inversely exceeded other unadjusted air-cooled roller ways, the parameter switching conditions of the adjacent rolling batches may be limited, for example, for the cooling control process parameters of the adjacent rolling batches, if the difference between the operating speeds of the air-cooled roller ways of the adjacent rolling batches is within a relatively stable range, it is considered that the roller way overtaking and being inversely exceeded does not occur, the parameter switching is allowed, if the difference between the operating speeds of the air-cooled roller ways of the adjacent rolling batches is not within the range, it is considered that there is a risk that the roller way overtaking and being inversely exceeded may occur, the rolling switching is not allowed at this time (but switching can be performed after waiting for a period of time), and a technician in the art can set the maximum parameter floating range of the adjacent rolling.
In some embodiments, for safety, a fixed delay time may be further added on the basis of the total passing time, so that when the total time of delay waiting from the starting time reaches "fixed delay time + T", the parameter of the target roller table is updated, thereby implementing safe step-by-step delay updating.
If a mode of executing new cooling control parameters to change parameters after the varieties corresponding to the old cooling control parameters on the air cooling line are completely collected from the air cooling line is adopted, the wire production line is allowed to start rolling the varieties corresponding to the new cooling control process parameters after the new cooling control parameters are changed, the speed difference of the air cooling roller way is considered, in the prior art, the whole variety switching process may need 4-9 minutes in different time periods, and if the varieties are changed for thousands of times in a year, a large amount of time is consumed in the parameter switching process. If the parameter switching is performed according to the embodiments of S262 and S272 provided in the embodiments of the present application, on one hand, the operation efficiency can be improved by reducing manual operations, and the time consumption is reduced, and on the other hand, due to the adoption of the step-by-step delay updating, the parameter switching can be started without waiting for the last batch of rolled stock to completely leave the air cooling line, so that the parameter switching can be completed on the air cooling line in advance, the time consumption in the variety switching process can be reduced, and the rolling operation efficiency can be effectively improved.
The production process information of the wire production line is collected by an execution system and a monitoring system conveniently. The wire rod production line is provided with a plurality of photoelectric detection elements, for example, photoelectric detection elements can be arranged at the inlet and outlet of a heating furnace, the inlet and outlet of a rolling mill unit, the inlet of a laying head and the outlet of an air cooling line, and the position of a processed steel material on the wire rod production line can be known based on the trigger state of each photoelectric detection element or the rotating speed and the torque of a rolling mill motor. The process that the monitoring system monitors the production process information acquired by the execution system and determines the production progress of the wire rod of the current rolling batch according to the production process information may include: and the execution system sends the triggering states of the photoelectric detection elements to the monitoring system as production process information. And the monitoring system determines the position of the billet in the current rolling batch according to the triggering states of the photoelectric detection elements.
When each steel billet enters the heating furnace, the furnace entering action triggers a corresponding photoelectric detection element on the heating furnace to output a corresponding photoelectric signal. The discharging action of each billet can also trigger a corresponding photoelectric detection element on the heating furnace to output a corresponding photoelectric signal. The monitoring system can know the wire processing progress of the heating furnace by identifying the signal change of each photoelectric detection element. The monitoring system can obtain steel biting/throwing signals of each rolling mill during rough rolling, medium rolling and finish rolling through the execution system, so that the wire processing progress of the rolling mill can be known. The monitoring system may feed back the wire processing progress to the planning system. When a discharge signal of one billet is detected, the monitoring system can bind the furnace temperature detected during discharge and the material number (rolling batch number + serial number) corresponding to the billet as the heating actual result of the billet, and send the heating actual result of the billet to the planning system.
In order to collect more comprehensive production process information, thermometers for detecting temperature are arranged on equipment such as a heating furnace, a rolling mill, a laying head and the like. The monitoring system may forward the temperature data detected by the various thermometers to the planning system.
The monitoring system can feed back parameters such as the roller way running speed, the opening degree of the heat preservation cover, the fan running frequency and the like of each section of air-cooled roller way on the air-cooled line to the planning system.
Through the implementation mode, the monitoring system can track the state of the rolling process, and feeds back the monitored data to the planning system after integrating and analyzing the monitored data.
Optionally, when it is determined that the wire rods of the current rolling batch leave the tail end of the air-cooling line, the monitoring system may send the currently acquired device operation parameters of the wire rod production line and the wire rod processing result as the rolling result to the planning system.
When the wires of the current rolling batch leave the tail end of the air cooling line, the corresponding photoelectric detection elements arranged on the air cooling line can generate photoelectric signal changes, and the monitoring system can determine whether the wires of the current rolling batch completely pass through the air cooling line by monitoring the photoelectric signal changes corresponding to the position, so that a wire processing result is obtained. When the situation that the wire rods of the current rolling batch leave the tail end of the air cooling line is determined, the monitoring system can send the steel temperature, the roller way running speed, the opening degree of the heat preservation cover, the fan frequency and the rolling batch number of the cold control processing completion collected at each position of the wire rod production line to the planning system as rolling results (rolling actual results). The user can make a new rolling plan according to the rolling result received by the planning system and the actual production requirement. Thereby facilitating closed loop rolling management.
Optionally, in order to ensure the data integrity of the process parameter issued each time, the planning system or the monitoring system may splice the process parameters into a string according to the communication requirement of the execution system, and the specific splicing logic is set according to a specifically-used PLC (programmable logic controller), for example, when the used PLC is a siemens series, the first bit of the spliced string header may define length information as 254(ubyte format), and the second bit may define number information as 254(ubyte format). When the technological parameters are spliced, the uniform length is used for splicing, if the length is not enough, 0 is supplemented (for example, if the speed value of the first section of the roller way is 1.3, and the length is defined as 3, 1.3 is converted into 1.30 when the parameters are issued), and spaces can be used for separating each technological parameter in the character string. The character strings can be written into the designated PLC addresses through an OPC protocol, and the execution system analyzes the character strings in the corresponding addresses, so that the process parameters are input and displayed in an operation interface.
In the whole rolling process parameter processing process, a system operation log can be generated so as to facilitate the follow-up data tracing.
It is understood that the specific values presented herein can be modified according to actual needs (e.g., the period of sending the update packets, the number of roller tracks, the number of production lines, etc.).
