Description

Technical Field

[0001] This invention relates to the field of steel production technology, and in particular to a hot rolling scheduling system and method with intelligent dynamic feedback adjustment. Background Technology

[0002] Steel production mainly includes processes such as ironmaking, steelmaking, continuous casting, and hot rolling. Among these, hot rolling is the process of continuously rolling and deforming continuously cast billets into steel products of various specifications and shapes. Hot rolling scheduling refers to the process of rationally arranging and scheduling the rolling schedule during hot rolling production, and it is a key link in improving production efficiency, reducing production costs, and minimizing energy consumption.

[0003] However, traditional hot rolling scheduling is often based on experience and manual adjustments, resulting in inefficiency, over-reliance on past experience, and unstable scheduling. Most existing hot rolling scheduling systems are traditional static methods with low levels of automation and intelligence, and cannot automatically adjust the scheduling plan in real time according to the actual production situation. Summary of the Invention

[0004] Based on the above analysis, the embodiments of the present invention aim to provide a hot rolling scheduling system and method with intelligent dynamic feedback adjustment, so as to solve at least one of the problems mentioned above, such as low efficiency of manual hot rolling scheduling, unstable scheduling, low degree of automation and intelligence of existing scheduling systems, and inability to adjust scheduling plans in real time.

[0005] On one hand, embodiments of the present invention provide a hot rolling scheduling system with intelligent dynamic feedback adjustment, including: a casting order module, used to receive casting order release information from the steel zone and slab information from the slab library, and generate slab preparation relationships based on the casting order release information and slab information; a rule library, used to store hot rolling scheduling rules; and a rolling process module, used to receive slab preparation relationships and call hot rolling scheduling rules, and generate a final rolling process plan based on the hot rolling scheduling rules and slab preparation relationships.

[0006] Furthermore, the material preparation relationship includes the continuous casting schedule to be scheduled and the inventory schedule to be scheduled; the casting module includes: a planned billet preparation module, which is used to receive casting release information and generate a cutting plan based on the casting release information, and to match and bind the cutting plan with the production order to generate the continuous casting schedule to be scheduled; and an inventory billet preparation module, which is used to obtain slab information and match and bind the slab information with the production order to generate the inventory schedule to be scheduled.

[0007] Furthermore, the casting module is also used to: convert slabs matched in the pending continuous casting plan into inventory slabs after they have been produced in actual production without scheduling, and convert the corresponding pending continuous casting plan into a pending inventory plan.

[0008] Furthermore, the rolling process module includes a material preparation library and a scheduling module; the scheduling module is used to synchronize the material preparation relationships obtained from the casting module to the material preparation library; the material preparation library is used to store the material preparation relationships for scheduling backup; the scheduling module is also used to select material preparation relationships from the material preparation library for scheduling and generate the final rolling process plan.

[0009] Furthermore, the system also includes: a user interface, which allows users to create basic information for the rolling mill plan; after the user creates the basic information for the rolling mill plan, the scheduling module is used to select the material preparation relationships in the material preparation library for scheduling, generate the final rolling mill plan and release the rolling mill.

[0010] Furthermore, the user interface is also used for users to set scheduling parameters; the scheduling module is used to automatically schedule the material preparation relationship according to the scheduling parameters, generate the final rolling schedule and release the rolling period.

[0011] Furthermore, the system also includes: a data acquisition module for real-time acquisition of actual production data during the continuous casting and hot rolling processes; and a casting module and a rolling stroke module for real-time dynamic adjustment of material preparation relationships and rolling stroke plans based on actual production data.

[0012] Furthermore, the casting sequence module is used to obtain online casting sequence release information in real time based on the occurrence of events in the steel zone, and to compare the online casting sequence release information with the pre-arranged casting sequence information in terms of attributes, and to make dynamic adjustments based on the comparison results.

[0013] Furthermore, the scheduling module is used to compare the rolling mill data of the system with the piece and slab information updated synchronously with the actual production. When an abnormality occurs where the rolling mill data is inconsistent with the actual piece or slab information, the scheduling module is used to recommend the production order or slab that needs to be replaced and to automatically replace it according to the hot rolling scheduling rules and the abnormality information.

[0014] On the other hand, embodiments of the present invention provide a hot rolling scheduling method with intelligent dynamic feedback adjustment, which is implemented using the system of the above embodiments. The method includes: receiving casting release information of the steel zone and slab information of the slab library; generating slab preparation relationship based on casting release information and slab information; calling hot rolling scheduling rules, and finally generating a rolling schedule based on hot rolling scheduling rules and slab preparation relationship.

[0027] To make the objectives, technical solutions, and advantages of the present invention clearer, exemplary embodiments of the present invention will be described below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention. For clarity and brevity, not all features of actual embodiments are described in the specification.

[0028] It should also be noted that, in order to avoid obscuring the invention with unnecessary details, only the device structure and / or processing steps closely related to the solution according to the invention are shown in the accompanying drawings, while other details that are not closely related to the invention are omitted.

[0029] Embodiments of the present invention provide a hot rolling scheduling system with intelligent dynamic feedback adjustment, such as... Figure 1 As shown, the hot rolling scheduling system includes: a casting sequence module, a rule base (not shown in the figure), and a rolling cycle module. The casting sequence module and the rolling cycle module can exchange information, and the rolling cycle module can exchange information with the rule base. Specifically, the casting sequence module receives casting sequence release information from the steel zone and slab information from the slab library, and generates slab preparation relationships based on these information. The rule base stores hot rolling scheduling rules. The rolling cycle module receives the slab preparation relationships generated by the casting sequence module, and can also call upon the hot rolling scheduling rules in the rule base to generate a rolling cycle plan based on the hot rolling scheduling rules and the slab preparation relationships.

[0030] The hot rolling scheduling system of the present invention can quickly and automatically generate a rolling schedule that meets the process requirements based on the currently released casting batch and the hot rolling scheduling rules in the rule library, thereby accelerating order conversion. It has a high degree of intelligence and automation and is easy to operate.

[0031] Specifically, the hot-rolling scheduling rules stored in the rule base include hot-rolling process rule requirements for different steel grades. These rules are pre-set rules based on industry-standard guidelines and the specific production requirements of each production plant, and feature or attributed to suit these requirements. Users can dynamically add to and modify the rule base as needed, providing fundamental data support for hot-rolling scheduling and its dynamic adjustments, providing rule requirements for system scheduling, and improving the reliability of hot-rolling scheduling. For example, hot-rolling scheduling rules include constraints such as width, thickness, and hardness.

[0032] In some embodiments, such as Figure 1 As shown, the casting module includes a planned billet preparation module and an inventory billet preparation module set up in parallel. These modules are used to match orders for the inventory billets in the current billet warehouse and the billets not produced in the current continuous casting process, so as to facilitate the hot rolling schedule of the billets to be arranged.

[0033] The planned billet preparation module receives casting release information, generates a cutting plan based on the casting release information, and matches and binds the cutting plan with the production order to generate a pending continuous casting plan. The inventory billet preparation module obtains slab information from the slab warehouse, matches and binds the slab information with the production order to generate a pending inventory plan. The pending continuous casting plan and the pending inventory plan constitute a preparation relationship.

[0034] In some embodiments, such as Figure 1 As shown, when the slab matched in the continuous casting plan is produced in actual production without being rolled, the casting module is also used to convert the slab into a stock slab and convert its corresponding continuous casting plan into a stock plan.

[0035] like Figure 1 As shown, in some embodiments, the slab information in the slab library can be synchronized to the hot rolling scheduling system through data synchronization or slab report output, so that the inventory slab preparation module can query and obtain slab information.

[0036] In addition, production orders can be synchronized to the hot rolling scheduling system, for example, through data synchronization or user input, so that the system can schedule hot rolling based on production orders. Production orders include piece-rate plans, which are stored in an order pool after the system receives them.

[0037] In some embodiments, the hot rolling scheduling system also includes a user interface for displaying various information during the hot rolling scheduling process, such as cutting plans, pending continuous casting plans, pending inventory plans, rolling schedules, and actual production data.

[0038] In some embodiments, the hot rolling scheduling system also includes a background manager, which is used to call various modules and transmit information and data through various interfaces to manage various modules and control the hot rolling scheduling process.

[0039] Specifically, the process for generating the continuous casting schedule is as follows: Figure 2 As shown, after receiving the casting release information from the steel zone, the background manager of the hot rolling scheduling system calls the casting information transmission interface of the casting module and transmits the casting plan information to the casting module. The casting module receives and parses the casting release information, generates a cutting plan, and then returns the cutting plan to the system background manager through the cutting plan transmission interface. The system background manager receives the parsed cutting plan and displays it on the user interface.

[0040] Furthermore, such as Figure 2As shown, while the casting module generates the cutting plan, the hot rolling scheduling system backend manager transmits the piece-by-piece plan order to the casting module through the piece-by-piece plan order pool interface. After the casting module's billet preparation module obtains the piece-by-piece plan order pool, it matches the cutting plan with the order to generate the continuous casting plan to be scheduled. Then, the system backend manager receives the casting plan matching order through the casting plan matching order receiving interface and displays it through the front-end user interface.

[0041] Specifically, the process for generating the pending inventory plan is as follows: Figure 3 As shown, when the user clicks "Auto Match Orders" on the user interface, the system backend manager calls the inventory billet preparation interface of the casting module. The inventory billet preparation module queries the current inventory of billets. At the same time, the system backend manager transmits the batch planned orders to the inventory billet preparation module through the batch planned order pool interface. After obtaining the batch planned order pool, the inventory billet preparation module matches the billet information with the batch planned orders to generate a pending inventory plan. The system backend manager calls the pending inventory plan transmission interface to receive the pending inventory plan from the inventory billet preparation module, and displays it on the user interface.

[0042] After the casting module generates the material preparation relationship, which includes the continuous casting schedule and the inventory schedule, the system can perform hot rolling scheduling based on the material preparation relationship.

[0043] like Figure 1 As shown, in some embodiments, the rolling mill module includes a material preparation library (not shown) and a scheduling module. The scheduling module is used to synchronize the material preparation relationships obtained from the casting module to the material preparation library, which stores the material preparation relationships for scheduling. The scheduling module is also used to select material preparation relationships from the material preparation library for scheduling and generate the final rolling mill plan.

[0044] In embodiments of the present invention, the user interface is also used to allow users to create basic information for a rolling mill schedule. This basic information includes the rolling mill name, rolling mill time, and interval duration. After the user creates the basic rolling mill schedule information, the scheduling module selects either the pending continuous casting plan or the pending inventory plan from the material reserve to schedule the rolling mill, generating the final rolling mill schedule and releasing the rolling mill.

[0045] The rolling mill module of this invention supports automatic scheduling, realizing the automation and intelligence of hot rolling scheduling. During automatic scheduling, the user interface allows users to set scheduling parameters; the scheduling module automatically schedules the material preparation relationship according to the scheduling parameters, generates the final rolling mill plan, and releases the rolling mill. The scheduling parameters include: rolling start time, rolling roll change time, etc.

[0046] Specifically, such as Figure 4As shown, during automatic scheduling, the user sets the scheduling parameters in the configuration and selects fully automatic scheduling. The system background manager calls the scheduling module through the fully automatic scheduling interface. The scheduling module selects the plans to be scheduled (i.e., the continuous casting plans and the inventory plans to be scheduled) from the material preparation library, adds them to the rolling schedule created by the user, and performs casting and rolling collaborative scheduling according to the scheduling parameters to generate the final rolling schedule. The system background manager receives the final rolling schedule through the rolling result interface and displays it through the user interface.

[0047] In some embodiments, the rolling process module is also used to perform statistical analysis on the KPIs of each rolling process to evaluate whether the scheduling results are reasonable and to provide a basis for optimizing the scheduling.

[0048] Specifically, such as Figure 4 As shown, when the scheduling module performs casting and rolling collaborative scheduling based on the scheduling parameters, it calculates the KPI for each rolling stroke and obtains the KPI statistics. The KPI statistics are returned to the system background manager through the rolling stroke KPI results interface, and the KPI statistics are displayed by the user interface.

[0049] In some embodiments, the rolling process module is also used to calculate the constraint satisfaction of each rolling process according to the hot rolling scheduling rules in the rule base, so as to ensure the rationality and reliability of the final rolling process plan.

[0050] After obtaining the KPI statistics, the rolling process module then calculates the constraint satisfaction status of each rolling process. If the process rules are violated, a constraint violation record is generated. The rolling process constraint violation record is transmitted to the system background manager through the rolling process constraint violation interface. After receiving the constraint violation record, the system background manager displays the constraint violation record through the user interface.

[0051] In some embodiments, when the rolling process violates process rule constraints, the rolling process module can also optimize the final rolling process plan to make it conform to the process rule requirements.

[0052] In addition, the rolling mill module also supports manual scheduling. Specifically, such as... Figure 5 As shown, users can add rolling runs in the user interface and add parts from production orders to the rolling runs, for example, by dragging or cutting. Users can manually adjust the parts in the rolling runs, for example, by deleting parts or changing the order of parts. During user rolling run adjustments, the system background manager calls the rolling run module, which performs constraint checks on the arrangement of parts and displays the check results through the user interface.

[0053] Specifically, during constraint checks, the system backend manager calls the rolling process module through the rolling process rule constraint check interface to calculate the compliance status of rolling process rule constraints. If the rolling process violates the rolling process rules, a constraint violation record is generated. This record is received from the rolling process module and transmitted to the system backend manager via the rolling process constraint violation interface, and then displayed on the user interface. Based on the constraint violation record, the user adjusts the number of pieces in the rolling process until the rolling process meets the process rule constraints.

[0054] In some embodiments, the hot rolling scheduling system further includes a data acquisition module for collecting actual production data during the continuous casting and hot rolling processes. The casting module and the rolling stroke module can dynamically adjust the material preparation relationship and rolling stroke plan in real time based on the actual production data, respectively.

[0055] Specifically, the data acquisition module can collect real-time production data from the steel production area, such as events occurring in the steel production area. Figure 6 As shown, the casting order module can obtain online casting order release information in real time based on the occurrence of steel mill events. These events can include: casting order status changes, casting order deletion, batch addition of casting order plans, manual creation / import of casting orders, casting order modification, heat order rescheduling, heat order confirmation, heat order reassignment, and heat order rework. Furthermore, the casting order module also supports users manually triggering the retrieval of online casting order release information; for example, users can manually click a button on the user interface to obtain the online casting order information for the current day.

[0056] After obtaining the online pouring release information, the pouring module can compare its attributes with the pre-scheduled pouring information and make dynamic adjustments based on the comparison results. The pre-scheduled pouring information refers to the pouring schedules that have already been planned before obtaining the online pouring release information.

[0057] Specifically, when the online release casting and the pre-arranged casting meet the predetermined matching conditions, the online release casting and the pre-arranged casting are bound together. Then, the pre-arranged casting information is changed according to the updated online release casting information. For example, inconsistent attributes of the online release casting can be replaced in the pre-arranged casting. The changed pre-arranged casting information may not meet the piece requirements of the production order. In this case, the casting module can track the rolling mill corresponding to the replaced pre-arranged casting based on the order matching records already in the scheduling and send a warning message to indicate that the slab of the pre-arranged casting does not match the order.

[0058] When the online release casting order and the pre-arranged casting order do not meet the predetermined matching conditions, the casting order module can create online casting order information and match and bind it with the production order, replacing the pre-arranged continuous casting plan already bound to the production order. The pre-arranged continuous casting plan is the continuous casting plan after the pending continuous casting plan has been processed by the scheduling plan. If the online casting order information replaces the pre-arranged continuous casting plan and enters the rolling mill, the casting order module can also track the corresponding rolling mill according to the replaced pre-arranged continuous casting plan and send a warning message to indicate that the online casting order and the piece order requirements do not match.

[0059] Meanwhile, when the final slab is actually produced, the casting module can also compare the specifications of the actual slab with the requirements of the production order. If the actual slab does not meet the requirements of the production order, the casting module can track its corresponding rolling process and send a warning message to indicate that the slab does not match the production order.

[0060] In some embodiments, the user interface may display the aforementioned warning information to remind the user.

[0061] like Figure 6 As shown, in some embodiments, when comparing the attributes of the online release casting information and the pre-arranged casting information, the number of steel grades, time, and the number of furnaces corresponding to the width of the casting can be compared.

[0062] For example, assuming online release castings include A and B, and pre-casting castings include a, b, c, and d, the matching relationships between the quantities of steel grades between the two include the following: a1, steel grade quantity A == a, B == b; a2, A is a subset of a, and the quantities are basically the same; a3, A is a subset of a, and the quantities are basically the same; a4, A and a have a small overlap in steel grades, but most are different. The matching relationships between the two in terms of time include: b1, A is later than a by ≥20 minutes; b2, the time difference between A and a is within 20 minutes; b3, A is earlier than a by ≥20 minutes. The matching relationships between the two in terms of the corresponding width of the casting include: c1, A > a; c2, A equals a; c3, A < a.

[0063] When comparing the attributes of online release pouring information and pre-arranged pouring information, the predetermined matching conditions between the two include simultaneously satisfying the matching conditions a1, b2, and c2. When this condition is met, the online release pouring information and the pre-arranged pouring information are bound together; when other matching conditions are met, online pouring information is created.

[0064] In terms of dynamic scheduling of pouring cycles, the system of this invention can acquire online pouring cycle information in real time for comparison, increase data accuracy, and issue early warning prompts, thus replacing workers in analysis.

[0065] In some embodiments, the rolling process module can dynamically adjust the final rolling process plan in real time based on the actual production data of the hot rolling process and the prompts and warnings sent by the casting module.

[0066] Specifically, such as Figure 6 As shown, after receiving a warning message from the casting module, the rolling process module can automatically adjust the rolling process information. Adjusting the rolling process information includes at least one of the following: creating a rolling process, deleting a rolling process, and editing a rolling process. For example, deleting the corresponding abnormal rolling unit in the rolling process and replacing it. In addition, the rolling process module also supports manual adjustment of the rolling process information by the user. When a warning message is displayed on the user interface, the user can manually replace the corresponding abnormal rolling unit according to the warning message.

[0067] After events such as rolling stroke creation, rolling stroke deletion, and rolling stroke editing are performed, the rolling stroke module identifies and processes them, converts them, issues a part update event, and pushes the event to the user interface for display.

[0068] Meanwhile, the data acquisition module collects slab production events in real time and obtains slab production reports to ensure that the data of virtual materials and physical materials corresponding to production orders are consistent with the actual data, and to achieve synchronization and real-time updates of slab information.

[0069] The scheduling module can compare the rolling mill data in the system with the batch and slab information updated synchronously with actual production. When an anomaly occurs where the rolling mill data in the system is inconsistent with the actual batch or slab information, the scheduling module can provide an information prompt to indicate the need for operations such as order change or slab change.

[0070] In some embodiments, the scheduling module can recommend orders or slabs that need to be replaced based on hot rolling scheduling rules and the aforementioned anomaly information, and automatically replace them. This real-time, intelligent, and dynamic adjustment reduces errors that may occur during manual operation, effectively saving production costs and improving production efficiency. Furthermore, the scheduling module also supports manual operation, i.e., manual replacement of orders or slabs.

[0071] In terms of rolling mill dynamic scheduling, the system of the present invention can obtain slab output reports in real time, so as to ensure that the data of virtual materials and physical materials corresponding to production orders are consistent with the actual situation. Through this data and the rolling mill data in the hot rolling scheduling system, real-time optimization scheduling is performed, which is highly intelligent and easy to operate.

[0072] The hot rolling scheduling system of this invention can quickly and automatically generate a rolling schedule that meets process constraints and steel grades based on the currently released casting information, slab information, and set scheduling parameters. This accelerates order conversion, ensures a high direct loading rate and hot loading rate in the rolling process, effectively reduces energy consumption during slab rolling, and saves costs for enterprises.

[0073] On the other hand, embodiments of the present invention also provide a hot rolling scheduling method, implemented using the hot rolling scheduling system of the above embodiments. The hot rolling scheduling method of the present invention includes: [The method includes:]

[0074] Receive casting release information from the steel zone and slab information from the slab warehouse;

[0075] The slab preparation relationship is generated based on the casting release information and slab information;

[0076] Call the hot rolling scheduling rules and generate the final rolling schedule based on the hot rolling scheduling rules and the slab preparation relationship.

[0077] The scheduling method of this invention for automatic hot rolling scheduling can reduce errors that may occur during manual operation, effectively save production costs and improve production efficiency.

[0078] Furthermore, the specific process and principle of the hot rolling scheduling method of the present invention are the same as those of the hot rolling scheduling system in the above embodiments, and will not be repeated here.

[0079] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in the present invention should be included within the scope of protection of the present invention.
