[0028] In order to make the purpose, 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 only used to explain the present invention and are not intended to limit the present invention. For the sake of clarity and conciseness, not all features of the actual implementation are described in the specification.

[0029] It is also necessary to explain here that, in order to avoid obscuring the present invention due to unnecessary details, only the device structure and / or processing steps closely related to the solution according to the present invention are shown in the accompanying drawings, while other details that are not closely related to the present invention are omitted.

[0030] The embodiment of the present invention provides a hot rolling scheduling system with intelligent dynamic feedback adjustment, such as Figure 1 As shown, the hot rolling scheduling system includes: a pouring module, a rule library (not shown in the figure) and a rolling process module. The pouring module and the rolling process module can exchange information, and the rolling process module and the rule library can exchange information. Among them, the pouring module is used to receive the pouring release information of the steel zone and the slab information of the slab library, and generate the slab preparation relationship according to the pouring release information and the slab information; the rule library is used to store the hot rolling scheduling rules; the rolling process module is used to receive the slab preparation relationship generated by the pouring module, and the rolling process module can call the hot rolling scheduling rules of the rule library, and generate a rolling process plan based on the hot rolling scheduling rules and the slab preparation relationship.

[0031] 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 pouring times and the hot rolling scheduling rules in the rule library, accelerate order conversion, have a high degree of intelligence and automation, and are easy to operate.

[0032] Specifically, the hot rolling scheduling rules stored in the rule library include hot rolling process rule requirements for different steel grades. They are rule characteristics or attributes set in advance based on the general industry standards and the special production requirements of the production plant. Users can dynamically add and modify the rule library as needed to provide basic data support for hot rolling scheduling and its dynamic adjustment, provide rule requirements for system scheduling, and improve the reliability of hot rolling scheduling. For example, the hot rolling scheduling rules include constraints such as width, thickness, and hardness.

[0033] In some embodiments, Figure 1 As shown, the casting module includes: a planned billet preparation module and an inventory billet preparation module arranged in parallel, which are respectively used to match orders for the inventory billets in the current billet warehouse and the unproduced billets in the current continuous casting process, so as to facilitate the subsequent hot rolling scheduling of the waiting billets.

[0034] Among them, the planned billet preparation module is used to receive the pouring release information and generate a cutting plan according to the pouring release information, and match and bind the cutting plan with the production order to generate a waiting continuous casting plan; the inventory billet preparation module is used to obtain the slab information of the slab warehouse, and match and bind the slab information with the production order to generate a waiting inventory plan. Among them, the waiting continuous casting plan and the waiting inventory plan constitute a preparation relationship.

[0035] In some embodiments, Figure 1 As shown, when the slab matched in the continuous casting plan to be scheduled has not undergone the rolling process and is produced in actual production, the casting module is also used to convert the slab into an inventory slab and convert its corresponding continuous casting plan to be scheduled into an inventory plan to be scheduled.

[0036] 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 the slab information.

[0037] In addition, the production order can be synchronized to the hot rolling scheduling system, for example, through data synchronization, user input, etc., so that the system can schedule hot rolling according to the production order. The production order includes a piece schedule, and the system stores the production order in the order pool after receiving it.

[0038] In some embodiments, the hot rolling scheduling system also includes a user interface for displaying various information in the hot rolling scheduling process, such as cutting plans, continuous casting plans to be scheduled, inventory plans to be scheduled, rolling schedules, actual production data, etc.

[0039] In some embodiments, the hot rolling scheduling system also includes a background manager for calling each module and transmitting information and data through various interfaces to achieve management of each module and control of the hot rolling scheduling process.

[0040] Specifically, the generation process of the continuous casting plan to be arranged is as follows: Figure 2 As shown, after the background manager of the hot rolling scheduling system receives the pouring release information of the steel zone, it calls the pouring information transmission interface of the pouring module and transmits the pouring plan information to the pouring module. The pouring module receives and parses the pouring 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.

[0041] Furthermore, if Figure 2As shown, while the casting module generates the cutting plan, the hot rolling scheduling system background manager transmits the piece plan order to the casting module through the piece plan order pool interface. After the billet preparation module of the casting module obtains the piece plan order pool, it matches the cutting plan with the order and generates a continuous casting plan to be scheduled. The system background manager then receives the casting plan matching order through the casting plan matching order receiving interface and displays it on the front-end user interface.

[0042] Specifically, the process of generating the inventory plan to be arranged is as follows: Figure 3 As shown, the user clicks on the automatic order matching in the user interface, and the system background manager calls the inventory blank material preparation interface of the casting module, and the inventory blank material preparation module queries the current inventory of slab information. At the same time, the system background manager transmits the piece plan order to the inventory blank material preparation module through the piece plan order pool interface. After the inventory blank material preparation module obtains the piece plan order pool, it matches the slab information and the piece plan order to generate an inventory plan to be arranged. The system background manager calls the inventory plan to be arranged transmission interface, receives the inventory plan to be arranged from the inventory blank material preparation module, and displays it on the user interface.

[0043] After the casting module generates the material preparation relationship including the continuous casting plan to be scheduled and the inventory plan to be scheduled, the system can perform hot rolling scheduling based on the material preparation relationship.

[0044] like Figure 1 As shown, in some embodiments, the rolling process module includes: a material preparation library (not shown in the figure) and a scheduling module. The scheduling module is used to synchronize the material preparation relationship obtained from the pouring module to the material preparation library, and the material preparation library is used to store the material preparation relationship for scheduling and standby; the scheduling module is also used to select the material preparation relationship from the material preparation library for scheduling and generating the final rolling process plan.

[0045] In an embodiment of the present invention, the user interface is also used for the user to create basic information of the rolling schedule. The basic information of the rolling schedule includes the name of the rolling schedule, the rolling schedule time, the interval duration, etc. After the user creates the basic information of the rolling schedule, the scheduling module selects the continuous casting schedule to be scheduled or the inventory schedule to be scheduled in the stock preparation library for scheduling, generates the final rolling schedule and releases the rolling schedule.

[0046] The rolling schedule module of the embodiment of the present invention supports automatic scheduling, realizing the automation and intelligence of hot rolling scheduling. During automatic scheduling, the user interface is also used for the user 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 schedule. Among them, the scheduling parameters include: rolling start time, rolling roll change time, etc.

[0047] Specifically, 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 to-be-scheduled plan from the stockpile (i.e., the to-be-scheduled continuous casting plan and the to-be-scheduled inventory plan), adds it 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 on the user interface.

[0048] In some embodiments, the rolling process module is also used to perform statistical analysis on the KPI of each rolling process to evaluate whether the scheduling results are reasonable and provide a basis for optimizing the scheduling.

[0049] Specifically, Figure 4 As shown, when the scheduling module performs casting and rolling collaborative scheduling according to the scheduling parameters, the KPI of each rolling process is calculated to obtain the KPI statistical results, and the KPI statistical results are returned to the system background manager through the rolling process KPI result interface, and the KPI statistical results are displayed by the user interface.

[0050] 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 to ensure the rationality and reliability of the final rolling process plan.

[0051] After calculating the KPI statistical results, the rolling process module then calculates the constraint satisfaction 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 the system background manager receives the constraint violation record, the constraint violation record is displayed on the user interface.

[0052] In some embodiments, when the rolling process violates the process rule constraints, the rolling process module can also optimize the final rolling process plan to make it meet the process rule requirements.

[0053] In addition, the rolling process module also supports manual scheduling. Figure 5 As shown, the user can add a rolling process in the user interface and add the pieces in the production order to the rolling process, for example, by dragging or cutting to add the pieces to the rolling process. The user can manually adjust the pieces in the rolling process, for example, delete the pieces or change the order of the pieces. During the user's adjustment of the rolling process, the system background manager calls the rolling process module, which performs a constraint check on the arrangement of the pieces and displays the check results through the user interface.

[0054] Specifically, when performing constraint checking, the system backend manager calls the rolling process module through the rolling process rule constraint checking interface to calculate the rolling process rule constraint satisfaction. If the rolling process violates the rolling process process rule, a constraint violation record is generated; through the rolling process constraint violation interface, the constraint violation record is received from the rolling process module and transmitted to the system backend manager, and the constraint violation record is displayed on the user interface. The user adjusts the number of pieces in the rolling process according to the constraint violation record until the rolling process meets the process rule constraint.

[0055] In some embodiments, the hot rolling scheduling system further includes a data acquisition module for collecting actual production data during the continuous casting process and the hot rolling process. The casting module and the rolling process module can respectively dynamically adjust the material preparation relationship and the rolling process plan in real time according to the actual production data.

[0056] Specifically, the data acquisition module can collect the actual production data of the steel zone in real time, such as steel zone events. Figure 6 As shown in the figure, the pouring module can obtain the online pouring release information in real time according to the occurrence of steel zone events. Among them, steel plant events may include: pouring state change, pouring deletion, batch addition of pouring furnace plans, manual creation / import of pours, pouring modification, furnace rescheduling, furnace confirmation and release, furnace order re-allocation, furnace rework, etc. In addition, the pouring module also supports users to manually trigger the acquisition of online pouring release information. For example, users can manually click a button in the user interface to obtain the pouring information released online that day.

[0057] 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 that has been scheduled before obtaining the online pouring release information.

[0058] Specifically, when the online release pouring times and the pre-scheduled pouring times meet the predetermined matching condition range, the online release pouring times are bound to the pre-scheduled pouring times, and then the pre-scheduled pouring times information is changed according to the updated online release pouring times information. For example, the inconsistent attributes of the online release pouring times can be replaced with the pre-scheduled pouring times. The changed pre-scheduled pouring times information may not meet the piece quantity requirements of the production order. At this time, the pouring times module can track the rolling process corresponding to the replaced pre-scheduled pouring times according to the order matching records that have entered the schedule, and send a prompt warning message to prompt that the slab of the pre-scheduled pouring times does not match the order.

[0059] When the online released pouring times and the pre-scheduled pouring times do not meet the predetermined matching condition range, the pouring time module can create online pouring time information, match and bind it with the production order, and replace the pre-scheduled continuous casting plan bound to the production order, where the pre-scheduled continuous casting plan is the continuous casting plan after the scheduled continuous casting plan is scheduled. If the online pouring time information replaces the pre-scheduled continuous casting plan and enters the rolling process, the pouring time module can also track the corresponding rolling process according to the replaced pre-scheduled continuous casting plan, and send a prompt warning message to prompt that the online pouring time does not match the piece number requirements.

[0060] At the same time, when the final slab is actually produced, the casting module can also compare the actual slab specification parameters with the production order requirements. If the actual slab does not meet the production order requirements, the casting module can track its corresponding rolling process and send a prompt warning message to indicate that the slab does not match the production order.

[0061] In some embodiments, the user interface may display the above-mentioned warning information to remind the user.

[0062] like Figure 6 As shown, in some embodiments, when the attributes of the pouring information and the pre-arranged pouring information are released on the comparison line, the number of steel types, time and the number of furnaces of the corresponding width of the pouring can be compared.

[0063] For example, assuming that the online release pouring times include A and B, and the pre-arranged pouring times include a, b, c, and d, the matching relationships between the two types of steel include the following: a1, the number of steel types A==a, B==b; a2, A is a few furnaces less than a, A is a subset of a, and the number is basically the same; a3, A is a few furnaces more than a, a is a subset of A, and the number is basically the same; a4, A has a small overlap with a steel type, and most of them are different. The matching relationship between the two times includes: b1, A is ≥20 minutes later than a; b2, the time difference between A and a is within 20 minutes; b3, A is ≥20 minutes earlier than a. The matching relationship between the corresponding width furnace numbers between the two includes: c1, A>a; c2, A is equal to a; c3, A<a.

[0064] When comparing the properties of online released pouring information and pre-scheduled pouring information, the predetermined matching condition range between the two includes simultaneously satisfying the matching conditions of a1, b2, and c2. When this condition is met, the online released pouring is bound to the pre-scheduled pouring; when other matching conditions are met, the online pouring information is created.

[0065] In terms of dynamic scheduling of pouring times, the system of the present invention can obtain online released pouring times information in real time for comparison, increase data accuracy, and issue early warning prompts, which can replace workers in analysis.

[0066] 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 prompt warning information sent by the casting module.

[0067] Specifically, Figure 6 As shown, after the rolling process module receives the prompt warning information from the casting module, the rolling process module can automatically adjust the rolling process information. Adjusting the rolling process information includes: 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 users to manually adjust the rolling process information. When the prompt warning information is displayed on the user interface, the user can manually replace the corresponding abnormal rolling unit according to the prompt warning information.

[0068] After the events of rolling process creation, rolling process deletion, rolling process editing, etc. are performed, the rolling process module identifies and processes them, converts them, issues a piece update event, and pushes the event to the user interface for display.

[0069] At the same time, the data acquisition module collects slab output events in real time and obtains slab output reports to ensure that the data of virtual materials and real materials corresponding to the production order are consistent with the actual situation, and realize the synchronization and real-time update of slab information.

[0070] The scheduling module can compare the rolling process data in the system with the piece number and slab information updated synchronously with the actual production. When there is an abnormal information that the rolling process data in the system is inconsistent with the actual piece number or slab information, the scheduling module can provide information prompts to indicate the need to change orders or slabs.

[0071] In some embodiments, the scheduling module can recommend the orders or slabs that need to be replaced and automatically replace them according to the hot rolling scheduling rules and the above-mentioned abnormal information, and make real-time intelligent dynamic adjustments to reduce the mistakes that may be caused by manual operation, effectively save production costs, and improve production efficiency. In addition, the scheduling module also supports manual operation, that is, manual operation to replace orders or slabs.

[0072] In terms of dynamic scheduling of rolling process, the system of the present invention can obtain slab output reports in real time, ensure that the data of virtual materials and real materials corresponding to production orders are consistent with the actual situation, and perform real-time optimization scheduling through this data and the rolling process data in the hot rolling scheduling system, with high intelligence and easy operation.

[0073] The hot rolling scheduling system of the embodiment of the present invention can quickly and automatically generate a rolling schedule that meets the process constraints and steel types based on the currently released casting information and slab information and the set scheduling parameters, accelerate order conversion, ensure that the rolling schedule has a high direct loading rate and hot loading rate, effectively reduce energy consumption in the slab rolling process, and save costs for the enterprise.

[0074] On the other hand, an embodiment of the present invention further provides a hot rolling scheduling method, which is implemented by using the hot rolling scheduling system of the above embodiment. The hot rolling scheduling method of the embodiment of the present invention comprises:

[0075] Receive pouring release information from the steel zone and slab information from the slab warehouse;

[0076] Generate slab preparation relationship based on pouring release information and slab information;

[0077] Call the hot rolling scheduling rules and generate the final rolling schedule based on the hot rolling scheduling rules and slab preparation relationship.

[0078] The scheduling method of the present invention is used to perform automatic hot rolling scheduling, which can reduce the errors that may be caused by manual operation, effectively save production costs, and improve production efficiency.

[0079] In addition, the specific process and principle of the hot rolling scheduling method of the present invention are the same as the process and principle of hot rolling scheduling performed by the hot rolling scheduling system of the above-mentioned embodiment, and will not be repeated here.

[0080] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by any technician familiar with the technical field within the technical scope disclosed by the present invention should be covered within the protection scope of the present invention.
