Moreover, 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 ferrous metallurgy production, billet continuous casting is a necessary procedure for producing wires and bars, and in current billet continuous casting production, there are generally corresponding steelmaking systems (superior systems, i.e., L3 systems) and continuous casting systems (continuous casting secondary systems and programmable logic controller process control systems, i.e., lower computer systems L1), and main parameters of the whole production process are tracked and controlled.
However, in the continuous casting production process, each ladle of molten steel is buffered by a tundish with certain molten steel and then enters a crystallizer and a casting flow, so that when square billet actual results are generated, the square billet actual results are difficult to correspond to each furnace of molten steel one by one, and the number of the casting blank of each casting blank is difficult to automatically generate 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, continuous casting production is multi-heat continuous casting, the middle part is provided with a tundish which always stores certain molten steel, and then the tundish is divided into a plurality of casting flows through a crystallizer for casting, and each flow is cut to length according to the technological requirements to produce casting blanks, so that the casting blanks which are newly cut are difficult to distinguish and define in which furnace number. The prior method mainly adopts a manual judgment and definition mode, which leads to the difficulty that the continuous casting of the square billet is difficult to realize automatic production of casting blank actual results and tracking.
Meanwhile, the continuous casting system generally manually or automatically sends the matched actual results of the furnace or the casting to a production process execution system (Manufacturing Execution System, namely an MES system) of a steelmaking system or a manufacturing enterprise after the furnace or the casting is finished, so that the problem that the square billet information is lagged and the square billet actual results cannot be tracked on line is caused.
In order to solve the technical problems, embodiments of the present application provide a continuous casting performance generating method, apparatus, device, and computer storage medium. The continuous casting performance generating system provided in the embodiment of the present application will be described first.
Fig. 1 shows a schematic structural diagram of a continuous casting performance generating system provided in an embodiment of the present application. As shown in fig. 1, a steelmaking system 1, a database system 4, and a continuous casting system 3 are connected to the outside of the continuous casting performance generation system 2. Wherein the database system 4 is also connected to a client 5.
Specifically, the steelmaking system 1 is a superior production management system of the continuous casting performance generation system 2, and issues relevant information such as a production schedule of billet continuous casting according to a production scheduling schedule. The continuous casting system 3 provides all real-time data of the control of the continuous casting process of the square billets for a programmable logic controller system (Programmable Logic Controller System, i.e., PLC system) related to the continuous casting production of the square billets, including individual casting flow PLCs, a common PLC and a crystallizer PLC. 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 on each production site and relevant places needing to track the casting blank production process and actual results in a webpage or client installation software mode, and is directly connected with the database system 4, and comprises interfaces such as planning and production monitoring, process monitoring, actual results inquiring, information maintenance, version upgrading and the like.

The plan receiving and processing module 21 may be configured to receive production plan information issued by the steelmaking system 1 and process the production plan information. The production plan information includes a production plan number before production, a furnace number, and a casting number.
The data and logic processing module 22 may be configured to receive the production process information sent by each PLC in the continuous casting system 3 and process the production process information. The production process information comprises weight information of a to-be-poured position, angle and direction information of a rotary table, ladle number information, pouring start information, final pouring information, tundish weight information, pouring position weight information, cutting information of each casting stream and/or sensor information of preset positions of each casting stream area and/or other information.
The event generating and furnace changing module 23 generates event information according to the information received by the plan receiving and processing module 21 and the data and logic processing module 22 and a preset logic relation, and triggers a mark position according to the event information.
The preset logic relationship comprises furnace changing logic. Specifically, the weight of molten steel is automatically calculated by utilizing a casting start event and a final casting event, the weight of the molten steel in a tundish and the size and weight of each casting blank in a casting blank plan are combined, how many casting blanks can be expected to be produced by the ladle of molten steel are automatically calculated, when the expected number of casting blanks (theoretical square blank number) is reached, the casting blanks are automatically changed to the next furnace number of molten steel, and the production and tracking of the casting blank actual results of the furnace number of molten steel are started.
The event processing and information matching module 24 executes the event based on the event information and the marker position, and matches the event with the production plan information. Specifically, the event processing and information matching module 24 may sequentially perform processing of related events in the event information according to the trigger positions, and match the events with the production plan information. After each event is processed, the corresponding event-triggered flag position is reset.
The actual result generating and tracking module 25 generates a cast blank actual result according to the information matched by the event processing and information matching module 24, and tracks the position of the cast blank actual result. Specifically, after the event processing and information matching module 24 performs information matching, a matching record and an event record are produced, casting blank actual results are automatically generated according to the matching record and the event record, and the casting blank positions are tracked and displayed in real time according to preset position information and events (defined position information and events).
In some embodiments, continuous casting performance generation system 2 further includes an information display module 26, a performance delivery module 27, and a database interface module.
The information display module 26 may display production plan information, actual casting results, and positions of actual casting results, and may also display related events and processing results during continuous casting. The display type of the information display module comprises production plan information display, actual result sending information display, event processing and result display, current furnace number, casting time and real-time display of the number of furnace casting blanks and furnace changing event display.
The actual results transmitting module 27 is configured to transmit the actual results of the cast slab and other relevant data stored in the database system 4 to the steelmaking system 1 at regular time intervals, as required.
In the continuous casting performance generating system 2, the plan receiving and processing module 21 may store the processed production plan information into the database system 4 through the database interface module 28, the data and logic processing module 22 may store the processed production process information into the database system 4, the event generating and furnace changing module 23 may store the event information into the database system 4, the event processing and information matching module 24 may store the processed event information into the database system 4, and the performance generating and tracking module 25 may store the generated casting performance and tracking data into the database system 4.
In the continuous casting performance generating system 2, the event generating and furnace changing module can also circularly read the related operation information and the real-time data change information in the database system 4 through the database interface module 28, and the event processing and information matching module 24 can regularly read the new event information received in the database system 4.
It should be noted that, information transmission between the continuous casting performance generating 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 casting performance in the continuous casting process in real time.
For ease of understanding, the flow of the cast slab actual results generation, tracking, and furnace change in the continuous casting actual results generation system 2 will be described below.
Fig. 2 is a schematic flow chart of casting blank generation, tracking and furnace changing provided in an embodiment of the present application. As shown in fig. 2, the flow of casting blank generation, tracking and furnace changing comprises automatic ladle loading logic processing, casting logic processing, furnace changing logic processing, actual performance generation and tracking, database updating and information display, event processing and information matching.
When the steel ladle automatic up logic processing starts to generate a casting blank, when the plan receiving and processing module 21 in the continuous casting performance generating system 2 receives the production plan information sent by the steelmaking system 1, the continuous casting 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, casting order number) in the production plan information, and stores the sorted production plan information in the production plan table in the system. Subsequently, the data and logic processing module 22 in the continuous casting performance generating system 2 receives the weight information of the position to be poured, the rotation table angle information, and the ladle number information in the production process information.
At this time, the event processing and information matching module 24 correlates the production process information with the information in the production schedule, that is, correlates the production schedule number, the furnace number, and the casting number in the production schedule information with the weight information of the position to be cast, the rotation table angle information, and the ladle number information in the production process information.
If the weight information of the to-be-poured position (namely, the weight sensor signal of the large ladle to-be-poured position) in the production process information is detected to be larger than the weight threshold of the to-be-poured position, a production plan number with the minimum to-be-poured position and the non-empty ladle number is searched in a production plan table under the condition that the weight of the to-be-poured position is larger than the weight threshold of the to-be-poured position, and the furnace number and other related information (namely, the to-be-poured position, the weight information of the to-be-poured position, the angle and the direction information of the rotating table and the ladle number) associated with the production plan number are sent to the to-be-poured position of the continuous casting system to indicate that the ladle associated with the production plan number is on the stage (namely, the ladle is operated to the to-be-poured position). At this time, if there is an abnormality (i.e., the ladle does not run to the position to be poured), manual adjustment can be performed by an operator.
After the ladle is moved to the casting position, whether the ladle is moved from the casting position to the casting position can be judged according to the angle and direction information of the rotary table (namely the angle signal change and the direction of the large ladle rotary table). Under the condition that the angle change information and the direction information of the rotating platform meet preset conditions, the continuous casting performance generating system 2 automatically brings related information of a production plan number corresponding to the steel ladle which is operated to the position to be poured into the pouring position, and empties the information corresponding to the steel ladle at the position to be poured. At this time, the furnace number and other related information of the production plan number corresponding to the ladle are converted into the furnace number of the to-be-poured position and other related information of the production plan number of the to-be-poured position.
Wherein, the weight threshold value of the to-be-poured position and the preset condition can be set manually according to the experience value. For example, a weight threshold of the to-be-poured position is set to be 100 tons; the setting of the preset condition comprises that the angle change of the rotary table exceeds an angle change threshold value, and the direction is shifted from the original direction to the east.
As the ladle is moved from the position to be poured to the pouring position, in the casting logic process, when the data in the continuous casting performance generating system 2 and the logic processing module 22 receive the pouring start information in the production process information (i.e., the continuous casting performance generating system 2 detects the large ladle pouring start signal sent by the PLC) in the case that the pouring position receives ladle information (i.e., the furnace number of the position to be poured is converted into the furnace number being poured and the furnace number being poured) and the pouring start event number is generated. At this time, the data and logic processing module 22 sends the start-up 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 start-up event number, generates a message of the start-up event, and sends the message of the start-up event to the steelmaking system 2.
At the same time, the start-up information triggers the update of the on-casting furnace number and on-casting heat information to the on-casting information for the ladle in the furnace change logic process (i.e., furnace change model).
When the ladle weight at the casting position is lower than the threshold value of the casting position and when the data and logic processing module 22 in the continuous casting performance generating system 2 receives the final casting information in the production process information (namely, the continuous casting performance generating system 2 detects the large ladle final casting signal sent by the PLC), the ladle information is converted into ladle information in a 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, generates a message of the final casting event, and sends the message of the final casting event to the steelmaking system. And simultaneously, removing the corresponding information of the ladle from the casting position.
In the furnace exchange logic process, the event generating and furnace exchange module 23 circularly reads relevant operation information and real-time data change information in the database system 4 through the database interface module 28, namely, the furnace exchange model stores the current casting furnace information and the cutting furnace information, and the current casting furnace information comprises a casting plan number (namely, a production plan number converted into a casting state), a furnace number (namely, a furnace number converted into a casting state), a casting plan number (namely, a production plan number converted into a casting state) with the steel grade and the casting weight corresponding to the cutting furnace information, a furnace number (namely, a furnace number converted into a casting state), a steel grade and the casting weight.
Meanwhile, according to the start-up information and the final-casting information of the casting heat (namely the heat being cast), the furnace changing model records the two weights of the casting heat, and the weight of the cast molten steel can be obtained by subtracting. According to the size information in the casting blank plan corresponding to the casting heat, the theoretical weight of a square blank (namely the casting blank) can be calculated. Specifically, the theoretical weight of a square billet is the square billet cross-sectional area multiplied by the square billet length multiplied by the density. Dividing the weight of the molten steel cast by the casting furnace by the theoretical weight of one square billet, and rounding to obtain the theoretical number of square billets which can be produced by the molten steel in the casting furnace.
The data and logic processing module 22 in the continuous casting performance generating system 2 receives each casting flow cutting information in the production process information, and obtains the actual cutting number and the theoretical cutting number. The actual cutting quantity comprises the quantity of the casting blank which is actually cut currently under the condition that a cutting signal is received; the theoretical cutting number comprises the cutting number of the actual cutting casting blank of the last heat or the average cutting number of the actual cutting casting blank of all the cutting heat before the current heat is cut;
when the actual cut number exceeds the theoretical cut number (i.e., when the actual cut count of each stream cut of the cutting heat is greater than or equal to the theoretical square billet count of the cutting heat), the heat exchange model updates the casting heat information to the cutting heat information and generates heat exchange events.
Note that, since the casting heat is not finished at this time, the theoretical square billet number of the casting heat is not calculated yet, the theoretical cutting number at this time is replaced by the actual casting billet number or the average casting billet number of the upper furnace, and once the casting heat is finished, the actual theoretical number of the furnace can be calculated immediately to replace the tentative average casting billet number of the heat. When a new furnace reaches a casting position and casting is started, the casting furnace information in the model is automatically replaced by the casting furnace information.
When the casting time of the casting heat is finished and the continuous casting machine overhauls, the furnace changing model pair is used for re-casting according to a ladle changing or casting stopping signal recorded by an operator, and two furnace changing strategies are generated. Firstly, if the casting blank is firstly cast after the ladle is changed, the first 15 cut casting blanks after the casting is cast are calculated into the previous cutting furnace time. And secondly, if the casting is started for the first time after stopping casting, calculating according to the current casting heat.
Under abnormal conditions, namely that the current cutting heat does not reach the theoretical cutting count yet, and the casting heat is finished in advance (namely that 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 molten steel.
When the ladle is cast, the ladle is required to be filled with the pouring basket through the water gap, then the pouring basket flows into the crystallizer and each casting flow through the water gap of the pouring basket, after the continuous casting machine stops casting and overhauls, about half of molten steel in the ladle cast at the upper stage is filled into the pouring basket to serve as a buffer tank, and then the pouring basket water gap is opened to enter the crystallizer and each casting flow, so that when the casting flows are solidified into casting blanks, the casting blanks are counted until the casting blanks start to be finally cast, only half of the molten steel in the second furnace is actually counted, and strictly speaking, only when the liquid level of the pouring basket is kept unchanged, the molten steel in the pouring basket is filled into the upper stage of the molten steel in the second furnace, and the casting blanks cut at the moment are molten steel in the second furnace after the same amount of molten steel is filled into the pouring basket as the buffer tank. 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 the generation of the cast slab 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 cast slab actual performance from the updated cutting heat information. Namely, the generation of the actual casting blank results is generated according to a casting blank plan corresponding to the current cutting heat of the furnace changing model.
When a PLC of a certain flow of the continuous casting machine generates a cutting signal, the continuous casting performance generating system 2 immediately generates a cutting event of the flow, generates a casting performance under the casting plan of the casting heat according to production plan information, and sends the casting performance to a steelmaking system.
After cutting according to the updated cutting heat information, acquiring a casting blank signal at a preset position, wherein the casting blank signal comprises position information of a furnace number of a steelmaking system corresponding to the updated cutting heat information detected by a sensor at the preset position; and tracking the position of the actual results of the casting blank according to the position information.
Specifically, after cutting is completed, when the infrared sensor at the subsequent set position (i.e. the preset position) of the casting flow detects a casting blank signal, the casting blank actual result generated by the casting flow recently reaches the position, and a human-computer interface (i.e. Human Machine Interface, HMI picture) is sent to display, when the steel turning signal of the casting flow appears, the casting blank actual result of the casting flow is indicated to be turned into a finished product area for storage, and when the corresponding straight roller way sensor signal appears, the casting blank actual result is indicated to be directly conveyed to the position of the next process. In summary, through the position definition of each sensor, the real-time tracking of the position of the generated casting blank actual results is realized, the positions of the casting blank actual results and the casting blank actual results can be sent to a database system for storage, the database is updated, and the positions of the casting blank actual results and the casting blank actual results can be sent to an information display module for real-time display on an HMI (human machine interface) for information display.
The event processing and information matching 24 matches the start-up event, the finish-up event, the furnace change event, and the cut and position event with the production planning information according to the time and position of the event occurrence, correlating the entire casting blank generation, tracking, and furnace change process.
