[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0023] In the present invention, descriptions such as "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in the field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0024] refer to Figure 1 As shown, Figure 1 Schematic diagram of the relationship between the target steel plate, the rolling residue and the target slab in the embodiment of the present invention, wherein: Figure 1The target steel plate in the rolling process includes sub-steel plate 1 and sub-steel plate 2. In the process of rolling the target slab to produce the target steel plate, in addition to obtaining sub-steel plate 1 and sub-steel plate 2, rolling residue is also obtained. If the length of the rolling residue is large, such as the length of the rolling residue is greater than 3m, then the rolling residue can continue to be used to produce steel plates. If the length of the rolling residue is small, such as the length of the rolling residue is less than 2.5m, although it cannot be used to produce steel plates, due to the small length, even if it is directly determined as unusable waste residue, it will not cause too much waste. However, the rolling residue with a length between 2.5m and 3m is a medium-sized residue, which is not only not suitable for the continued production of steel plates, but also causes serious waste of materials. It is usually treated as a waste residue. Therefore, it should be avoided that the rolling residue of the target slab is a medium-sized residue. The embodiment of the present invention provides the following method:

[0025] Figure 2 is a flow chart of a production control method for a steel plate in an embodiment of the present invention. The present invention provides a production control method for a steel plate. Figure 2 As shown, the method includes the following steps S101 to S104:

[0026] S101: Obtain specification information of the target steel plate to be produced.

[0027] In some embodiments, obtaining specification information of a target steel plate to be produced may include: obtaining multiple orders; selecting a group of orders from the multiple orders, wherein the steel type and thickness of the sub-steel plates of each order in the group of orders are the same; and combining the sub-steel plates of each order in the group of orders to obtain the specification information of the target steel plate.

[0028] refer to Figure 3 As shown, Figure 3 Two schematic diagrams of obtaining target steel plates from a group of orders in an embodiment of the present invention are shown. Figure 3 (a) is a schematic diagram of the first combination, where a group of orders includes sub-steel plate 1, sub-steel plate 2 and sub-steel plate 3, and the target steel plate does not include steel plate residues. Figure 3 (b) is a schematic diagram of the second combination, where a group of orders includes sub-steel plate 4, sub-steel plate 5, sub-steel plate 6, sub-steel plate 7 and sub-steel plate 8, and the target steel plate includes steel plate residual material.

[0029] S102: Based on the specification information of the target steel plate, determine the target slab required for rolling the target steel plate.

[0030] In some embodiments, the target slab thickness is a preset slab thickness, the target slab width is a preset slab width, and the specification information of the target steel plate includes the steel plate length. Step S102 may include the following steps S1021 to S1022:

[0031] S1021: Determine the slab length of the target slab based on the steel plate length and the preset trimming length.

[0032] It should be noted that, since the edge quality of the target slab after rolling is low, it needs to be trimmed first, and then the target steel plate is cut out from the target slab after rolling. The preset trimming length refers to the trimming length of the target slab after rolling.

[0033] In some embodiments, the specification information of the target steel plate also includes the steel plate width and the steel plate thickness. Then, step S1021 may include: taking the sum of the steel plate length and the preset trimming length as the first theoretical length; determining the second theoretical length based on the first theoretical length, the steel plate width, the steel plate thickness, the slab thickness and the slab width; based on the second theoretical length, selecting an actual length from multiple preset actual lengths as the slab length, the multiple actual lengths are the actual lengths of multiple slabs, and the slab length is greater than the second theoretical length.

[0034] In some embodiments, the second theoretical length is determined based on the first theoretical length, steel plate width, steel plate thickness, slab thickness and slab width, which can be: taking the product of the first theoretical length, steel plate width and steel plate thickness as the theoretical volume; taking the quotient of the theoretical volume divided by the slab thickness as the first numerical value; taking the quotient of the first numerical value divided by the slab width as the second numerical value; taking the second numerical value as the second theoretical length.

[0035] For example, assuming that the target slab thickness is 300mm, the target slab width is 2000mm, the target steel plate thickness is 20mm, the target steel plate width is 3000mm, the target steel plate length is 17200mm, the preset trimming length is 2000mm, and the multiple actual lengths are 1800mm, 1900mm, 2200mm, and 2400mm. Then, the first theoretical length is 19200mm and the theoretical volume is 1152000000mm. 3 , the first value is 3840000, the second value is 1920, so the second theoretical length is 1920mm. Then, an actual length is selected from multiple actual lengths as the slab length, and the slab length is greater than the second theoretical length. Specifically, the actual length with the smallest difference from the second theoretical length can be selected, such as 2200mm, so the slab length is 2200mm. In addition, since the slab length is the actual length with the smallest difference from the second theoretical length among multiple actual lengths, it ensures full utilization of the slab, avoids excessive residual material of the slab after rolling, and improves the yield rate of the slab.

[0036] S1022: Select a target slab from a plurality of slabs of different specifications based on the slab thickness, the slab width, and the slab length.

[0037] Continuing with the example of step S1021, the specification information of the target slab is that the slab thickness is 300 mm, the slab width is 2000 mm, and the slab length is 2200 mm.

[0038] It should be noted that the embodiment of the present invention limits the target slab thickness to a preset slab thickness and the target slab width to a preset slab width, so only the slab length needs to be calculated to determine the target slab, which reduces the amount of calculation and improves the calculation efficiency, thereby enabling the target slab to be determined as quickly as possible and accelerating the production efficiency of the steel plate. This achieves both reducing the waste of slabs after rolling and improving the production efficiency of the steel plate.

[0039] S103: Based on the target steel plate and the target slab, determine the actual yield rate of the target slab.

[0040] In some embodiments, determining the actual yield rate of the target slab based on the target steel plate and the target slab may include: determining the steel plate volume of the target steel plate based on the specification information of the target steel plate; determining the slab volume of the target slab based on the specification information of the target slab; and taking the quotient of the steel plate volume and the slab volume as the actual yield rate.

[0041] Continuing with the example of step S1022, the volume of the target steel plate is 1032000000mm 3 , the target slab volume is 1320000000mm 3 , so the actual yield rate is 78.18%.

[0042] S104: If the actual yield rate is within the allowable range of the yield rate of the target slab, the target slab is rolled to produce the target steel plate. The allowable range of the yield rate of the target slab makes the length of the rolling residue of the target slab less than the first preset length or greater than the second preset length, and the second preset length is greater than the first preset length.

[0043] In some embodiments, the first preset length may be 2.5 m, and the second preset length may be 3 m. The length of the rolling residue of the target slab is less than the first preset length, indicating that the length of the rolling residue is small and cannot be used to produce steel plates, but due to the small length, it will not cause too much waste. The length of the rolling residue of the target slab is greater than the second preset length, indicating that the length of the rolling residue is large and the rolling residue can be used to produce steel plates.

[0044] For example, assuming that the allowable range of the yield rate of the target slab is (0, 77.27%) and (79.55%, 100%], then if the actual yield rate is 78.18%, that is, the actual yield rate is not within the allowable range of the yield rate of the target slab, rolling of the target slab is not allowed. If the actual yield rate is 76.18%, that is, the actual yield rate is within the allowable range of the yield rate of the target slab, rolling of the target slab is allowed.

[0045] In some embodiments, before rolling the target slab to produce the target steel plate, it may also include: inputting the specification information of the target slab and the specification information of the target steel plate into a preset correspondence to obtain the prohibited range of the yield of the target slab, so that the length of the rolling residue of the target slab is not less than the first preset length and not greater than the second preset length; based on the prohibited range of the yield of the target slab, determine the allowable range of the yield of the target slab.

[0046] It should be noted that, assuming that the prohibited range of the target slab yield rate is [77.27%, 79.55%], the allowed range of the yield rate is (0, 77.27%) and (79.55%, 100%).

[0047] It should be noted that the preset correspondence is equivalent to a database, which stores in advance the correspondence between the specification information of the target slab, the specification information of the target steel plate and the prohibited range of the yield rate of the target slab. When the relevant data is needed, it can be quickly extracted, avoiding on-site calculations based on the information, thus avoiding an increase in the amount of calculation, improving the calculation speed, and improving the production efficiency of the steel plate, thereby achieving both reducing the waste material of the slab after rolling and improving the production efficiency of the steel plate.

[0048] In some implementations, the preset correspondence relationship may be established through the following steps S1041 to S1046:

[0049] S1041: Acquire multiple groups of production data, each group of production data including specification information of a slab and specification information of a steel plate.

[0050] It should be noted that the multiple sets of production data include combinations of various slabs and various steel plates.

[0051] S1042: taking each set of production data in the multiple sets of production data as target production data in turn.

[0052] S1043: Determine an upper threshold value of the yield rate of the slab in the target production data based on the specification information of the slab in the target production data, the specification information of the steel plate in the target production data, and the first preset length.

[0053] In some embodiments, step S1043 may include: determining the length of the slab after rolling in the target production data based on the specification information of the slab in the target production data and the specification information of the steel plate in the target production data; determining the upper limit threshold of the yield rate of the slab in the target production data based on the specification information of the slab in the target production data, the specification information of the steel plate in the target production data, the length after rolling, the preset trimming length and the first preset length.

[0054] In some embodiments, determining the upper limit threshold of the yield rate of the slab in the target production data based on the specification information of the slab in the target production data, the specification information of the steel plate in the target production data, the length after rolling, the preset trimming length and the first preset length can include: taking the difference between the length after rolling and the preset trimming length as the first remaining length; taking the difference between the first remaining length and the first preset length as the second remaining length; determining the first volume based on the second remaining length, the width of the steel plate in the target production data and the thickness of the steel plate in the target production data; determining the second volume based on the width, thickness and length of the slab in the target production data; and taking the quotient of the first volume and the second volume as the upper limit threshold of the yield rate of the slab in the target production data.

[0055] In some embodiments, based on the specification information of the slab in the target production data and the specification information of the steel plate in the target production data, the length of the slab after rolling in the target production data is determined, which can be: based on the width, thickness and length of the slab in the target production data, a second volume is determined; the quotient of the second volume divided by the thickness of the steel plate in the target production data is used as a third value; the quotient of the third value divided by the width of the steel plate in the target production data is used as the length after rolling.

[0056] For example, assuming that the width of the slab in the target production data is 2000mm, the thickness is 300mm, and the length is 2200mm, the thickness of the steel plate in the target production data is 20mm, and the width of the steel plate in the target production data is 3000mm, then the second volume is 1320000000mm 3 , the third value is 66000000, so the length after rolling is 22000mm.

[0057] S1044: Determine a lower limit threshold of the yield rate of the slab in the target production data based on the specification information of the slab in the target production data, the specification information of the steel plate in the target production data, and the second preset length.

[0058] In some embodiments, step S1044 may include: determining the lower limit threshold of the yield rate of the slab in the target production data based on the specification information of the slab in the target production data, the specification information of the steel plate in the target production data, the length after rolling, the preset trimming length and the second preset length.

[0059] In some embodiments, based on the specification information of the slab in the target production data, the specification information of the steel plate in the target production data, the length after rolling, the preset trimming length and the second preset length, the lower limit threshold of the yield rate of the slab in the target production data is determined, which can be: taking the difference between the first remaining length and the second preset length as the third remaining length; determining the third volume based on the third remaining length, the width of the steel plate in the target production data and the thickness of the steel plate in the target production data; taking the quotient of the third volume and the second volume as the lower limit threshold of the yield rate of the slab in the target production data.

[0060] S1045: The upper threshold of the yield rate is used as the upper limit value of the prohibited range of the yield rate of the slab in the target production data, and the lower threshold of the yield rate is used as the lower limit value of the prohibited range of the yield rate of the slab in the target production data, so as to obtain the prohibited range of the yield rate of the slab in the target production data.

[0061] S1046: Based on the specification information of multiple sets of production data and their corresponding prohibited ranges of yield rates, a preset corresponding relationship is obtained.

[0062] It should be noted that with the continuous improvement of living standards, the use of steel has gradually increased, and the market competition in the steel industry has become increasingly fierce. The improvement of production yield can effectively reduce production costs and is the core indicator pursued by various steel companies to improve their competitiveness. In the actual production process, due to the restrictions on the specifications of the slabs by the heating furnace and the roller, only several specified slab types can be produced. In the case of fewer orders, a slab cannot be fully utilized when assembling the plates, but production must be scheduled to meet the delivery date. At this time, even if a minimum slab is used, after rolling out a mother plate and cutting out the contract small plate as planned, there is usually a steel plate without a corresponding contract left. To determine whether this steel plate is a finished steel plate, there are requirements for the length. When the length is too small to be judged as a residual steel plate, it can only be judged as scrap recycling, resulting in waste. Assuming that the minimum length requirement is greater than 3 meters, when the length of steel plate 3 is between 2.5 meters and 3 meters, the amount of scrap is large, which has a greater impact on the yield rate. Because the specifications of the billet types for production and rolling are different, the specifications of the large plates for rolling are also different, and the corresponding plate assembly design restricted areas are different. Manual control cannot be accurately controlled, and the situation that the small plates produced are too small and cannot be sold often occurs, resulting in waste and low production yield. Therefore, the embodiment of the present invention first classifies all the slab specifications that can be produced, and then sorts out the large plate specifications that can be rolled by the slabs under different classifications, quantifies the influence of the small plates in the large plates whose length falls in the range of 2.5 meters to 3 meters on the yield, and then designs the yield rate prohibited range. Then, a rule and procedure library is established: the yield rate prohibited ranges under different classifications are entered into the rule and procedure library, that is, the yield rate prohibited ranges corresponding to a certain specification of large plates under a certain specification of slabs are maintained in the rule and procedure library. After that, a plate assembly model is built: in combination with plate assembly professionals, the plate assembly production scheduling rules are collected, and the contracts of the same steel grade and thickness are combined to design the large plate specifications, and the slab specifications are reversed according to the principle of volume invariance to form the slab demand and calculate the design yield. Finally, the prohibited range of yield rate is automatically checked: according to the designed slab specifications, large plate specifications and panel assembly design yield rate, the prohibited range of yield rate in the rule and procedure library is automatically retrieved. When the yield rate of this design does not fall within the prohibited range of yield rate, the panel assembly design result is output to guide production.

[0063] It should be noted that the embodiment of the present invention also includes system architecture design, rule and procedure library design, and line simulation platform design. In the system architecture design, in order to ensure that the production line can be produced normally, the original system assembly function must be guaranteed to be used normally. That is, under the premise that the original process remains unchanged, the entry point of the assembly model is specified, and the newly entered contract passes through the residual steel plate assembly model, the residual slab billet assembly model, and the steel plate assembly model in turn, and according to the rule and procedure library, the assembly yield rate is maximized. The orders are collected and summarized, and the orders of the same steel grade and thickness are combined. The three assembly design processes of residual steel plate assembly, residual slab billet assembly, and steel plate assembly are passed in turn. The optimal results that do not fall into the prohibited range of the assembly yield rate are output to guide on-site production. In the design of the rule and procedure library, it has the characteristics of maintainable rule parameters, which is used to manage the input and output rules and parameters of the residual steel plate assembly model, the residual slab billet assembly model, and the steel plate assembly model. Users can modify the assembly restricted area parameters as needed, realizing the configurability of the rules. In the design of the parallel line simulation platform, in order to provide the model with real operation scenarios and data, a parallel line simulation platform based on CPS (physical information system) technology was built. It mainly includes the following modules: data scenario synchronization module: when the business is manually scheduled or the model is used for scheduling, the platform will take a photo of the data scenario of the scheduling at that time, and synchronize this scenario to the parallel line environment as the real data for verifying the model; simulation data preparation module: the simulation platform processes the data in this scenario and generates input data for model operation; simulation task management module: this module is responsible for managing the data operation tasks of each scenario. First, the simulation data preparation module establishes operation tasks and sorts the tasks. When the model completes the operation of the previous scenario or is in idle state, the model is called to perform data simulation operation of the next scenario; simulation result data display module: the model simulation results are synchronized to the business decision-making system in real time through the Goldengate technology. By designing statistical effect indicators, the scheduling data of the production environment and the parallel line simulation environment are displayed, so as to achieve a clear comparison and display of the operation of the model and provide optimization direction for the model. In addition, the parallel simulation platform has built a full-scale timing operation module, which captures the full-scale contract and full-scale surplus material information in the system at 2 o'clock every morning, synchronizes the new contract of the day, and calls the model at 23 o'clock at night to carry out full-scale operation, and calls the surplus material steel plate assembly model, the surplus material slab billet assembly model, the steel plate assembly model, the furnace assembly model, and the model operation effect in turn, and displays the model operation effect. The embodiment of the present invention quantifies the prohibited range of yield rate of large plates of different specifications under different billet shapes, and then maintains it in the rule and procedure library. By building an automatic assembly model, automatic verification is realized, and the design results that do not fall into the prohibited range of yield rate are output to guide on-site production.Through this method, the designed yield rate was increased by 0.88%, and the actual production yield rate was increased by 0.48%, which reduced the generation of waste and improved the utilization rate of wind, water, electricity, gas and other energy inputs in production, creating relatively considerable economic benefits for the company.

[0064] The embodiment of the present invention obtains the specification information of the target steel plate to be produced; determines the target slab required for rolling the target steel plate based on the specification information of the target steel plate; determines the actual yield rate of the target slab based on the target steel plate and the target slab; if the actual yield rate is within the allowable range of the yield rate of the target slab, the target slab is rolled to produce the target steel plate, and the allowable range of the yield rate of the target slab makes the length of the rolling residue of the target slab less than the first preset length or greater than the second preset length, and the second preset length is greater than the first preset length. The length of the rolling residue of the target slab is less than the first preset length, indicating that the length of the rolling residue is small and cannot be used to produce steel plates, but due to the small length, it will not cause too much waste. The length of the rolling residue of the target slab is greater than the second preset length, indicating that the length of the rolling residue is large, and the rolling residue can be used to produce steel plates. Therefore, the waste residue of the slab after rolling is reduced.

Among them, the preset corresponding relationship is established through the following steps: obtaining multiple groups of production data, each group of production data in the multiple groups of production data includes specification information of a slab and specification information of a steel plate; taking each group of production data in the multiple groups of production data as target production data in turn; determining the upper limit threshold of the yield rate of the slab in the target production data based on the specification information of the slab in the target production data, the specification information of the steel plate in the target production data and the first preset length; determining the lower limit threshold of the yield rate of the slab in the target production data based on the specification information of the slab in the target production data, the specification information of the steel plate in the target production data and the second preset length; taking the upper limit threshold of the yield rate as the upper limit value of the prohibited range of the yield rate of the slab in the target production data, and taking the lower limit threshold of the yield rate as the lower limit value of the prohibited range of the yield rate of the slab in the target production data, so as to obtain the prohibited range of the yield rate of the slab in the target production data; obtaining the preset corresponding relationship based on the specification information of multiple groups of production data and their corresponding prohibited range of yield rate.
