It should be understood that the specific embodiments described herein are merely illustrative of, and not restrictive on, the present application. It will be apparent to one skilled in the art that the present application may be practiced without some of these specific details. The following description of the embodiments is merely intended to provide a better understanding of the present application by illustrating examples thereof.

Also, the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus.

In the production of ferrous metallurgy, continuous casting of a billet is a necessary process for producing wire rods and bar materials, and in the current continuous casting of a billet, a steel-making system (an upper-level system, namely an L3 system) and a continuous casting system (a continuous casting secondary system and a programmable logic controller process control system, namely a lower-level system L1) which correspond to each other are generally adopted to track and control main parameters of the whole production process.
However, in the continuous casting production process, each ladle of molten steel enters the crystallizer and the casting flow after being buffered by a tundish with certain molten steel, so that when the actual performance of the square billet is generated, the molten steel is difficult to correspond to each ladle of molten steel one by one, and the casting blank number of each casting blank is difficult to be automatically generated in real time according to a production plan and a cutting event in the continuous casting production process, and is sent to a steelmaking system or other information systems in real time.
Specifically, because the continuous casting production is multi-furnace continuous casting, the middle part of the continuous casting is divided into a plurality of casting flows through a crystallizer after passing through a tundish which always stores certain molten steel, and each flow is cut to length according to the process requirements to generate a casting blank, the furnace number of the newly cut casting blank is difficult to distinguish and define. The method mainly adopts a manual judgment and definition mode, which causes the difficulty that the billet continuous casting is difficult to realize the automatic production of the actual performance and tracking of the casting blank.
Meanwhile, after the furnace or the casting time is completed, the continuous casting System manually or automatically sends the matched actual performance of the furnace or the casting time to a steel-making System or a Manufacturing enterprise production process Execution System (namely, an MES System), so that the problems that the information of the square billet is lagged and the actual performance of the square billet cannot be tracked on line are caused.
In order to solve the technical problem, embodiments of the present application provide a continuous casting actual performance generation method, device, equipment, and computer storage medium. First, a continuous casting performance generating system provided in an embodiment of the present application will be described.
Fig. 1 shows a schematic structural diagram of a continuous casting performance generating system provided by an embodiment of the present application. As shown in fig. 1, a steel making system 1, a database system 4, and a continuous casting system 3 are connected to the outside of the continuous casting achievement generating system 2. Database system 4 is also connected to client 5.
Specifically, the steel making system 1 is a superior production management system of the continuous casting achievement generating system 2, and issues a production plan of continuous casting of a billet and other related information according to a production scheduling plan. The continuous casting System 3 is a Programmable Logic Controller System (PLC System) related to the continuous billet casting, and includes each casting stream PLC, a common PLC, and a crystallizer PLC, and provides all real-time data for controlling the continuous billet casting process. The database and file storage system (i.e., database system 4) is a specialized database server responsible for storing data request responses for planning data, real-time data, event data, and performance data. The client 5 is installed in each production site and related places needing to track the production process and actual performance of the casting blank in a webpage or client installation software mode, is directly connected with the database system 4, and comprises interfaces of planning and production monitoring, process monitoring, actual performance query, information maintenance, version upgrading and the like.
The continuous casting achievement generation system 2 includes a plan receiving and processing module 21, a data and logic processing module 22, an event generation and shift module 23, an event processing and information matching module 24, and an achievement generation and tracking module 25.
The plan receiving and processing module 21 may be configured to receive the production plan information issued by the steel making system 1, and process the production plan information. The production plan information includes a production plan number, a furnace number and a casting number before production.
And the data and logic processing module 22 can be used for receiving the production process information sent by each PLC in the continuous casting system 3 and processing the production process information. The production process information comprises weight information of a position to be cast, angle and direction information of a rotating table, steel ladle number information, casting start information, final casting information, tundish weight information, casting position weight information, casting flow cutting information and/or sensor information of preset positions of casting flow areas and/or other information.
And the event generating and furnace changing module 23 is used for generating event information according to the information received by the plan receiving and processing module 21 and the data and logic processing module 22 and according to a preset logic relationship, and triggering the mark position according to the event information.
Wherein the preset logic relationship comprises furnace changing logic. Specifically, the weight of molten steel is automatically calculated by utilizing a start casting event and a final casting event, how many casting blanks can be expected to be produced by the molten steel in a ladle is automatically calculated by combining the weight of the molten steel in a tundish and the size and the weight of each casting blank in a casting blank plan, and when the number of the casting blanks (the number of theoretical square blanks) which are expected to be generated is reached, the molten steel in the next furnace number is automatically changed, and the casting blank actual performance of the molten steel in the furnace number is started to be produced and tracked.
And an event processing and information matching module 24 for executing the event according to the event information and the mark position and matching the event with the production plan information. Specifically, the event processing and information matching module 24 may sequentially execute the processing of the relevant events in the event information according to the trigger flag positions and match the events with the production plan information. After each event is processed, the mark position triggered by the corresponding event is reset.
And the actual performance generating and tracking module 25 generates the casting blank actual performance according to the information matched by the event processing and information matching module 24 and tracks the position of the casting blank actual performance. Specifically, after the event processing and information matching module 24 performs information matching, a matching record and an event record are produced, a casting blank actual performance is automatically generated according to the matching record and the event record, and the position of the casting blank is tracked and displayed in real time according to preset position information and events (defined position information and events).
In some embodiments, the continuous casting performance generation system 2 further includes an information display module 26, a performance transmission module 27, and a database interface module.
The information display module 26 can display production plan information, casting blank actual performance and the position of the casting blank actual performance, and can also display related events and processing results in the continuous casting process. The display types of the information display module comprise production plan information display, actual performance sending information display, event processing and result display, current furnace number, casting times and the number of casting blanks of the furnace in real time display and furnace changing event display.
And the actual performance sending module 27 is used for sending the actual performance of the casting blank and other related data stored in the database system 4 to the steelmaking system 1 at regular time according to the requirement.
In the continuous casting performance generating system 2, the schedule receiving and processing module 21 can store processed production schedule information into the database system 4, the data and logic processing module 22 can store processed production process information into the database system 4, the event generating and furnace changing module 23 can store event information into the database system 4, the event processing and information matching module 24 stores processed event information into the database system 4, and the performance generating and tracking module 25 stores produced casting blank performance and tracking data into the database system 4 through the database interface module 28.
In the continuous casting performance generating system 2, the event generating and furnace changing module can also read the relevant operation information and the real-time data change information in the database system 4 in a circulating way through the database interface module 28, and the event processing and information matching module 24 can read new event information received in the database system 4 in a timing way.
It should be noted that information transmission between the continuous casting actual results generation system 2 and the steelmaking system 1, the database system 4, the continuous casting system 3 and the client 5 can be performed in real time, so as to obtain the actual results of the casting blanks in the continuous casting process in real time.
For the sake of understanding, the following description will be made with respect to the flow of the casting blank performance generation, tracking, and furnace change in the continuous casting performance generation system 2.
FIG. 2 is a schematic flow diagram of casting blank generation, tracking and furnace change provided by the embodiment of the application. As shown in fig. 2, the process of casting blank generation, tracking and furnace change includes automatic steel ladle loading logic processing, casting logic processing, furnace change logic processing, actual performance generation and tracking, database updating and information display, and event processing and information matching.
When a casting blank is generated, in the automatic loading logic processing of the ladle, when the plan receiving and processing module 21 in the continuous casting actual performance generating system 2 receives the production plan information sent by the steelmaking system 1, the continuous casting actual performance generating system 2 deletes all unprocessed information in the production plan table in the system, sorts the received production plan information according to the casting number (namely, the casting number) in the production plan information, and stores the sorted production plan information into the production plan table in the system. Subsequently, the data and logic processing module 22 in the continuous casting actual performance generating system 2 receives the weight information of the to-be-cast position, the angle information of the rotating table and the steel ladle number information in the production process information.
At this time, the event processing and information matching module 24 associates the production process information with information in the production schedule, that is, the production schedule number, the furnace number, and the casting number in the production schedule information are associated with the to-be-cast station weight information, the turntable angle information, and the ladle number information in the production process information.
If the weight information of the to-be-cast position (namely the weight sensor signal of the to-be-cast position of the large ladle) in the production process information is detected to be larger than the weight threshold of the to-be-cast position, in the production schedule, under the condition that the weight of the to-be-cast position is larger than the weight threshold of the to-be-cast position, a production schedule number with the minimum casting number and the steel ladle number not empty is searched, and a furnace number and other related information (namely the casting number, the weight information of the to-be-cast position, the angle and direction information of the rotating table and the steel ladle number) related to the production schedule number are sent to the to-be-cast position of the continuous casting system to be used for indicating that the steel ladle related to the production schedule number is placed on the platform (namely the steel ladle is operated to the to-be-cast position). At this time, if there is an abnormality (i.e., the ladle is not moved to the position to be poured), the operator can manually adjust the operation.
After the ladle is operated to the position to be cast, whether the ladle is operated to the casting position from the position to be cast can be judged according to the angle and the direction information of the rotating platform (namely the angle signal change and the direction of the large ladle rotating platform). Under the condition that the angle change information and the direction information of the rotating platform meet the preset conditions, the continuous casting actual performance generating system 2 automatically brings the relevant information of the production plan number corresponding to the steel ladle which is operated to the position to be cast into the casting position, and clears the information corresponding to the steel ladle at the position to be cast. At the moment, the furnace number corresponding to the ladle and other related information of the production plan number are converted into other related information of the furnace number of the position to be poured and the production plan number of the position to be poured.
Wherein, the weight threshold value of the position to be poured and the preset condition can be manually set according to the empirical value. For example, setting the weight threshold of the to-be-poured position to be 100 tons; the preset condition is set to include that the angle change of the rotating platform exceeds an angle change threshold value, and the direction deviates to the east from the original direction.
With the operation of the ladle from the position to be cast to the casting position, in the casting logic processing, when the casting position receives ladle information (i.e. other related information of the furnace number and the production plan number corresponding to the ladle), and when the data and logic processing module 22 in the continuous casting actual performance generating system 2 receives start-casting information in the production process information (i.e. the continuous casting actual performance generating system 2 detects a large ladle start-casting signal sent by the PLC), the ladle information is converted into ladle information in the casting state (i.e. the furnace number of the position to be cast is converted into the furnace number being cast, and the furnace number information being cast is generated), and a start-casting event number is generated. At this time, the data and logic processing module 22 sends the casting start event number to the event processing and information matching module 24, and the event processing and information matching module 24 performs information matching according to the processing logic corresponding to the casting start event number, generates a telegraph text of the casting start event, and sends the telegraph text of the casting start event to the steel making system 2.
At the same time, the casting start information triggers the updating of the casting furnace number and the casting furnace number information to the casting information of the ladle in the furnace change logic processing (i.e. furnace change model).
When the weight of the ladle at the casting position is lower than the weight threshold value of the casting position along with the casting, and when the data and logic processing module 22 in the continuous casting actual performance generating system 2 receives the final casting information in the production process information (namely the continuous casting actual performance generating system 2 detects a large ladle final casting signal sent by the PLC), the ladle information is converted into the ladle information in the final casting state, and a final casting event number is generated. At this time, the data and logic processing module 22 sends the final casting event number to the event processing and information matching module 24, and the event processing and information matching module 24 performs information matching according to the processing logic corresponding to the final casting event number to generate a telegraph text of the final casting event and send the telegraph text of the final casting event to the steel-making system. At the same time, the information corresponding to the ladle is removed from the casting position.
In the furnace change logic processing, the event generation and furnace change module 23 circularly reads the relevant operation information and the real-time data change information in the database system 4 through the database interface module 28, that is, the furnace change model stores the current casting furnace number and cutting furnace number information, and includes the casting plan number corresponding to the casting furnace number information (that is, the production plan number converted into the casting state), the furnace number (that is, the furnace number converted into the casting state), the steel grade and the casting start weight corresponding to the cutting furnace number information (that is, the production plan number converted into the casting state), the furnace number (that is, the furnace number converted into the casting state), the steel grade and the casting start weight.
Meanwhile, the furnace changing model records the weight of the two times of the casting heat according to the casting start information and the casting end information of the casting position heat (namely the casting heat), and the weight of the cast molten steel can be obtained by subtracting the weight of the cast molten steel. According to the size information in the casting blank plan corresponding to the casting heat, the theoretical weight of a square blank (namely a casting blank) can be calculated. Specifically, the theoretical weight of a billet is the billet cross-sectional area multiplied by the billet length multiplied by the density. The weight of the molten steel cast by the casting furnace is divided by the theoretical weight of one square billet, and the theoretical square billet number which can be produced by the molten steel of the casting furnace can be obtained by taking the whole.
The data and logic processing module 22 in the continuous casting actual performance generating system 2 receives each casting cutting information in the production process information, and obtains the actual cutting quantity and the theoretical cutting quantity. The actual cutting number comprises the number of the current actual cutting casting blanks under the condition of receiving the cutting signals; the theoretical cutting number comprises the cutting number of the actual cutting casting blank for cutting the last furnace or the average cutting number of the actual cutting casting blanks for all the cutting furnaces before the current furnace is cut;
when the actual cutting number exceeds the theoretical cutting number (namely when the actual cutting count cut by each stream of the cutting furnace is greater than or equal to the theoretical billet count of the cutting furnace), the furnace changing model updates the casting furnace information into the cutting furnace information and generates a furnace changing event.
It should be noted that, at this time, since the casting heat is not finished and the theoretical number of square billets of the casting heat is not calculated, the theoretical number of cut is replaced by the actual number of cast billets or the average number of cast billets in the upper furnace, and once the casting heat is finished, the actual number of theoretical billets of the furnace can be calculated immediately to replace the average number of cast billets in the tentative heat. When a new furnace is put on the casting position and casting is started, the casting-starting furnace number information automatically replaces the casting-starting furnace number information in the model.
When the casting time of the casting furnace is finished and the continuous casting machine is overhauled, the furnace changing model pair carries out recasting according to a ladle changing or casting stopping signal recorded by an operator, and two furnace changing strategies are generated. Firstly, if the casting is started for the first time after the ladle is changed, the casting blank cut by the front 15 billets after the casting is started is counted into the previous cutting furnace. And secondly, if the casting is started for the first time after the casting is stopped, calculating according to the current casting furnace time.
Under the abnormal condition that the current cutting heat does not reach the theoretical cutting count, and the casting heat is in advanced final casting (namely a final casting signal is received in advance), a forced furnace changing event is generated, the furnace is directly switched to the final casting heat, and the theoretical casting blank count of the furnace is calculated according to the net weight of the molten steel.
It should be noted that, when a large ladle of molten steel (ladle) is cast, it is necessary to first enter a tundish through a water gap, and then flow into a crystallizer and each casting flow through the water gap of the tundish, after the continuous casting machine stops casting and maintenance, about half of the molten steel in the ladle cast at the upper stage is poured into the tundish as a buffer pool, and then the water gap of the tundish is opened to enter the crystallizer and each casting flow, so when the molten steel is solidified into a casting blank and is cut, the casting blank is counted until the molten steel in the furnace is finally poured, and strictly speaking, only when the liquid level of the tundish is kept unchanged, the molten steel in the tundish at the upper stage of the molten steel in the second furnace is poured into the same amount of molten steel as that in the tundish injected from the first furnace as the buffer pool, the cut casting blank is the molten steel in the second furnace. Based on this, the data and logic processing module 22 in the continuous casting performance generation system 2 will also receive the tundish weight in order to improve the accuracy of generating the casting billet performance.
In the actual performance generation and tracking, the actual performance generation and tracking module 25 in the continuous casting actual performance generation system 2 generates the actual performance of the cast slab based on the updated cutting heat information. That is, the actual casting product performance is generated by a casting product plan corresponding to the current cutting heat of the furnace change model.
When a PLC of a certain flow of the continuous casting machine generates a cutting signal, the continuous casting actual result generation system 2 immediately generates a cutting event of the flow, generates a casting blank actual result under the casting blank plan of the casting furnace according to production plan information, and sends the casting blank actual result to the steel-making system.
After cutting is finished according to the updated cutting heat information, a casting blank signal at a preset position is obtained, wherein the casting blank signal comprises position information of a furnace number of the steelmaking system, which corresponds to the updated cutting heat information and is detected by a sensor at the preset position; and tracking the position of the actual performance of the casting blank according to the position information.
Specifically, after cutting, when an infrared sensor at a subsequent set position (i.e. a preset position) of the casting flow detects a casting blank signal, a casting blank actual result recently generated by the casting flow reaches the position, and a Human Machine Interface (HMI picture) is sent to display the result. In conclusion, the position of the actual performance of the casting blank is generated and tracked in real time by defining the position of each sensor, the actual performance of the casting blank and the position of the actual performance of the casting blank can be sent to a database system for storage and updating, and the actual performance of the casting blank and the position of the actual performance of the casting blank can be sent to an information display module for real-time display on an HMI (human machine interface) for information display.
Event processing and information matching 24 matches the start casting event, the end casting event, the furnace change event and the cutting and position event with production plan information according to the time and position of the event, and associates the whole casting blank generation, tracking and furnace change process.
