Description

Technical Field

[0001] This invention relates to the field of steel production technology, and in particular to an automatic billet information tracking and receiving / dispatching control method based on a steel rolling heating furnace. Background Technology

[0002] The steelmaking continuous casting billet is sent to the heating furnace of the steel rolling mill. In between, it needs to pass through the hot conveyor roller, the transverse pusher, the elevator, the hot conveyor receiving roller, the cold charging receiving roller, the weighing roller, and the furnace entry (length measurement) roller.

[0003] In steelmaking, each batch of 4-5 billets is fed into the heating furnace sequentially. During this process, the steelmaking system cannot know the weight and length of each billet, and the rolling system cannot know which batch of billets is being fed into the furnace. Due to the lack of feedback on process and results, the collaborative work of the steel rolling system is prone to bottlenecks. Therefore, this invention proposes an automatic billet information tracking and receiving control method based on the rolling furnace to solve the problems existing in the prior art. Summary of the Invention

[0004] To address the aforementioned issues, this invention proposes an automatic billet information tracking and receiving control method based on a steel rolling heating furnace. This method quickly, accurately, and in real-time decodes the billet encoding data sent from the steelmaking process, enabling fully automatic billet tracking from the hot conveyor roller to the furnace. It then matches the weighing, length measurement, and temperature data with the steelmaking flow data, re-matches and returns the data to the steelmaking process, facilitating collaborative operation of the steel rolling system.

[0005] To achieve the objectives of this invention, the invention is implemented through the following technical solution: an automatic billet information tracking and receiving / dispatching control method based on a steel rolling heating furnace, comprising the following steps:

[0006] Step 1: Receive billet coding information from the steelmaking system via a gateway communication device between steelmaking and rolling.

[0007] Step 2: Determine if the encoded information is correct. If it does not conform to the rules, return to receive the encoded information again and return an error instruction to the steelmaking system.

[0008] Step 3: Upon receiving data that conforms to the rules, the information decoding module is invoked to perform protocol decoding on the received data;

[0009] Step 4: Generate a tracking sequence from the decoded data according to the data definition, which is used to identify the arrangement position and quantity of hot billets on the stand;

[0010] Step 5: Based on the tracking sequence, the system calls the billet tracking module to track the position of the billet in the conveyor chain in real time and update the positioning data;

[0011] Step Six: During the tracking process, new weighing, length measurement, and temperature data will be generated and incorporated into the additional information packaging module;

[0012] Step 7: After packaging is complete, inject the new additional information packet into the tracking sequence;

[0013] Step 8: Call the FIFO information flow management module to determine whether the billet has moved;

[0014] Step 9: Repeat the above steps until hot conveying and loading stops.

[0015] A further improvement is made in step one, where the flow code Billet_Code of the hot-cast billet is transmitted from the steelmaking system SM_sys to the rolling mill heating furnace system HF_sys via an industrial Ethernet gateway interconnection device connected to the steelmaking and rolling mill systems.

[0016] A further improvement is made in step two, where the judgment process is as follows: A falling edge signal CMD1_NDGE is generated when each group of billets passes through the No. 1 gate cold metal detector. The falling edge signal CMD1_NDGE triggers an event to determine whether the encoded information is correct. At this time, the system will check the data according to the following specific encoding rules: Billet_Code=SS1 1000+SS2 100+SS3 10+SS4 1. The Billet_Code is a combination of the five numbers 5, 4, 3, 2, and 1. Any number outside the rules or data with a number of digits not equal to 4 is considered illegal data.

[0017] A further improvement is made in step three, where the information decoding module uses a specific encoding rule as the decoding protocol. When the billet arrives at the transfer roller, the decoding sequence starts from the first billet when the direction is T_Left and from the fourth billet when the direction is T_Right. The decoding action condition is the next forward pushing action signal after the pusher moves backward to the position signal. After the decoding action is executed, Billet_Code is decomposed into four independent data.

[0018] Further improvements are made in the following: In step four, a fixed data storage space SRT.OP

[30] is allocated in the system specifically for storing the decoded data. The data generates a tracking sequence according to the order of decoding and is temporarily stored in the data temporary storage area of ​​SRT.OP

[30] to identify the arrangement position and quantity of hot billets on the stand.

[0019] A further improvement is made in step five, where the billet tracking module operates under the control of the gate trigger timing command: First, after the billet information is injected into the tracking sequence, it indicates that billets are temporarily stored on the platform. When the system controls the steel pusher to push the steel forward, the foremost billet on the platform is pushed into the hot billet receiving trough. Then, the system starts the elevator to hook the hot billet from the receiving trough and transport it to the hot conveying receiving roller conveyor. At this time, the second gate cold metal detector is triggered to generate a CMD2_PEDG command. The CMD2_PEDG command controls the billet tracking module. The block removes the current billet information from the tracking sequence SRT.OP

[30] and stores it in the data transfer area RS_DATA of the hot feeding receiving roller; then, the billet is transported to the cold billet receiving weighing roller. When the tail of the billet passes the third gate cold metal detector, a CMD3_NEDG instruction is generated. This instruction controls the billet tracking module to remove the current billet information from the data transfer area RS_DATA and store it in the data transfer area LS_DATA of the cold feeding receiving weighing roller, and completes the weighing and length measurement process for the current billet.

[0020] A further improvement is made in step six, after the data transfer, billet weighing and length measurement processes are completed, when the billet passes through the furnace roller conveyor, the CMD4_NEDG command of the fourth gate cold metal detector is triggered. This command controls the additional information packaging module to encode the generated weighing, length measurement and temperature data into a temporary data packet.

[0021] A further improvement is made in step seven, where a fixed data storage space SRT.MP

[300] is allocated in the system to store the information data of each billet, and the data is injected into the tracking sequence in the order of stacking.

[0022] A further improvement is made in step eight: if the billet has not moved, the system returns to the FIFO information flow management module; if the billet moves and is positioned at the next location, the system calls the billet information sending module to transmit the current billet information data through the gateway item steelmaking system SM_sys.

[0023] The beneficial effects of this invention are as follows:

[0024] 1. This invention can quickly, accurately, and in real time decode the billet encoding data sent from the steelmaking process, realize fully automatic billet tracking from the hot conveyor roller to the furnace, and then match the weighing, length measurement, and temperature data with the steelmaking flow data, and rematch and return it to the steelmaking process, which facilitates the coordinated work of the steel rolling system.

[0025] 2. This invention integrates the real-time tracking system with steelmaking data, effectively guiding production process adjustments and scheduling, improving the heat delivery rate of heating furnaces, significantly reducing energy consumption, and shortening the production cycle.

[0027] To enhance understanding of the present invention, the present invention will be further described in detail below with reference to embodiments. These embodiments are only used to explain the present invention and do not constitute a limitation on the scope of protection of the present invention.

[0028] Example 1

[0029] according to Figure 1 As shown in the figure, this embodiment proposes an automatic billet information tracking and receiving / dispatching control method based on a steel rolling heating furnace, including the following steps:

[0030] Step 1: Receive billet coding information from the steelmaking system via a gateway communication device between steelmaking and rolling.

[0031] Step 2: Determine if the encoded information is correct. If it does not conform to the rules, return to receive the encoded information again and return an error instruction to the steelmaking system.

[0032] Step 3: Upon receiving data that conforms to the rules, the information decoding module is invoked to perform protocol decoding on the received data;

[0033] Step 4: Generate a tracking sequence from the decoded data according to the data definition, which is used to identify the arrangement position and quantity of hot billets on the stand;

[0034] Step 5: Based on the tracking sequence, the system calls the billet tracking module to track the position of the billet in the conveyor chain in real time and update the positioning data;

[0035] Step Six: During the tracking process, new weighing, length measurement, and temperature data will be generated and incorporated into the additional information packaging module;

[0036] Step 7: After packaging is complete, inject the new additional information packet into the tracking sequence;

[0037] Step 8: Call the FIFO information flow management module to determine whether the billet has moved;

[0038] Step 9: Repeat the above steps until hot conveying and loading stops.

[0039] This invention can quickly, accurately, and in real time decode the billet encoding data sent from the steelmaking process, realize fully automatic billet tracking from the hot conveyor roller to the furnace, and then match the weighing, length measurement, and temperature data with the steelmaking flow data, and rematch and return it to the steelmaking process, which facilitates the coordinated work of the steel rolling system.

[0040] Example 2

[0041] according to Figure 1As shown in the figure, this embodiment proposes an automatic billet information tracking and receiving / dispatching control method based on a steel rolling heating furnace, including the following steps:

[0042] Receive billet coding information from the steelmaking system;

[0043] The flow code Billet_Code of the hot-cast billet is transmitted from the steelmaking system SM_sys to the rolling mill heating furnace system HF_sys via an industrial Ethernet gateway communication device connected to the steelmaking and rolling mill systems.

[0044] The system checks if the encoded information is correct. If it does not conform to the rules, it returns to receive the encoded information again and sends an error instruction to the steelmaking system. If it conforms to the rules, it proceeds to the next step.

[0045] A falling edge signal CMD1_NDGE is generated when each group of billets passes through the cold metal detector at gate 1. The falling edge signal CMD1_NDGE triggers an event to determine whether the encoded information is correct. At this time, the system will check the data according to the following encoding rules: Billet_Code=SS1 1000+SS2 100+SS3 10+SS4 1. Furthermore, Billet_Code can only be a combination of the five numbers 5, 4, 3, 2, and 1. Any number outside the rules or data with a number of digits not equal to 4 is considered invalid data.

[0046] After receiving legitimate data, the information decoding module is invoked to perform protocol decoding on the received data;

[0047] The decoding protocol of the information decoding module is the encoding rule in step 2 above. When the billet arrives at the transfer roller conveyor, according to the pushing direction of the transverse pusher, if the direction is T_Left, the decoding sequence starts from the first billet; if the direction is T_Right, the decoding sequence starts from the fourth billet. The decoding action condition is the next forward pushing action signal after the pusher has retreated to its position signal. After the decoding action is executed, Billet_Code is decomposed into 4 independent data.

[0048] The decoded data is injected into the tracking sequence according to the data definition;

[0049] A fixed data storage space SRT.OP

[30] is allocated in the system specifically for storing the decoded data. These data are used to generate a tracking sequence according to the order of decoding, and are temporarily stored in the data temporary storage area of ​​SRT.OP

[30] to identify the arrangement position and quantity of hot billets on the stand.

[0050] After generating the tracking sequence, the system calls the billet tracking module to track the position of the billet in the conveyor chain in real time and update the positioning data;

[0051] The billet tracking module operates under the control of the gate trigger timing instructions: First, after the billet information is injected into the tracking sequence, it indicates that these billets are temporarily stored on the stand. When the system controls the steel pusher to push the steel forward, the first billet on the stand is pushed into the hot billet receiving trough. Next, the system starts the elevator to hook up the hot billet in the receiving trough and transport it to the hot conveying receiving roller. At this time, the second gate cold metal detector will be triggered to generate a CMD2_PEDG instruction. The CMD2_PEDG instruction controls the billet tracking module to remove the current billet information from the tracking sequence SRT.OP

[30] and store it in the data transfer area RS_DATA of the hot feeding roller conveyor; next, the billet is transported to the cold billet receiving roller conveyor (weighing roller conveyor). When the tail of the billet passes the third gate cold metal detector, a CMD3_NEDG instruction is generated. This instruction controls the billet tracking module to remove the current billet information from the data transfer area RS_DATA and store it in the data transfer area LS_DATA of the cold feeding roller conveyor (weighing roller conveyor), and complete the weighing and length measurement process for the current billet.

[0052] During the tracking process, new data such as weight, length, and temperature will be generated and incorporated into the additional information packaging module;

[0053] After completing the data transfer, billet weighing and length measurement processes, when the billet passes through the furnace roller conveyor, the CMD4_NEDG command of the fourth gate cold metal detector is triggered. This command controls the additional information packaging module to encode the generated weighing / length measurement / temperature and other data into a temporary data packet.

[0054] After the additional information data is packaged, the new additional information packet is injected into the tracking sequence;

[0055] A fixed data storage space SRT.MP

[300] is allocated in the system specifically for storing the information data of each billet. This data is injected into the tracking sequence according to the order of stacking.

[0056] The FIFO information flow management module is called to determine whether the billet has moved. If the billet has not moved, the FIFO information flow management module is returned. If the billet has moved and is positioned at the next location, the billet information sending module is called to transmit the current billet information data through the gateway item steelmaking system SM_sys.

[0057] The above process is repeated until hot conveying and loading stops.

[0058] This invention rapidly, accurately, and in real-time decodes the billet encoding data sent from the steelmaking process, enabling fully automated billet tracking from the hot conveyor rollers to the furnace. It then matches the weighing, length measurement, and temperature data with the steelmaking flow rate data, re-matching and returning the data to the steelmaking process, facilitating collaborative operation within the steel rolling system. Furthermore, this invention integrates the real-time tracking system with steelmaking data, effectively guiding production process adjustments and scheduling, improving the heating furnace's hot delivery rate, significantly reducing energy consumption, and shortening the production cycle.

[0059] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed.
