[0002] Due to the need for precision in steel processing, senior technicians currently need to determine the post-cutting process flow of the steel based on relevant information, and then formulate a production plan based on this flow. This production plan then controls the steel processing equipment to process the steel. Different types of steel require different process flows, and different production plans are needed for different processes. This necessitates senior technicians formulating multiple production plans, leading to a heavy workload and increased operating costs. Summary of the Invention

[0042] The technical solutions in the embodiments of this application will be described in detail below with reference to the embodiments of this application.

[0043] It should be understood that the methods, situations, categories, and classifications of embodiments in this application are only for the convenience of description and do not constitute any limitation on this application. Various methods, categories, situations, and features in the embodiments can be combined with each other without contradiction.

[0044] It should also be understood that the terms "first," "second," "third," "fourth," and "fifth" in the embodiments of this application are for distinction only and do not constitute any limitation on this application. It should also be understood that in the various embodiments of this application, the sequence number of each process does not imply the execution order of the steps; the execution order of the steps is determined by their internal logic and does not constitute any limitation on the execution process of the embodiments of this application.

[0045] Due to the need for precision in steel processing, senior technicians currently need to determine the post-cutting process flow of the steel based on relevant information, and then formulate a production plan based on this flow. This production plan then controls the steel processing equipment to process the steel. Different types of steel require different process flows, and different production plans are needed for different processes. This necessitates senior technicians formulating multiple production plans, leading to a heavy workload and increased operating costs.

[0046] Based on the problems in related technologies, this application proposes a method for determining a production plan and a system for processing steel. The method is executed by a controller and includes: obtaining the composition, specifications, and uses of N cross-cut steel pieces, where each of the N steel pieces has the same composition, specifications, and uses; determining the first process flow for the N steel pieces based on their composition, specifications, and uses, where the first process flow includes a heat treatment process, a packaging process, a weighing process, and a warehousing process; determining the positions for each process within the first process flow and the number of personnel required for each position; obtaining the quantity of steel that the heat treatment process within the first process flow can process per unit time; and determining the time required for the heat treatment process of the N steel pieces based on the quantity of steel that the heat treatment process can process per unit time and the total quantity of steel N. The production plan for the N steel pieces includes the positions for each process within the first process flow, the number of personnel required for each position, and the time required for the heat treatment process of the N steel pieces. The controller in this application obtains the steel process flow and production plan based on relevant steel information, avoiding the need for senior technicians to determine different process flows and production plans based on different steel information, thus reducing their workload and lowering their operating costs.

[0047] The technical solutions of this application will be described in detail below with specific embodiments. These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments.

[0048] Figure 1 A flowchart illustrating the method for determining a production plan provided in this application embodiment is shown below. Figure 1 As shown, the method includes:

[0049] S110, the controller obtains the composition, specifications and uses of the N steel pieces after cross-section, and each of the N steel pieces has the same composition, specifications and uses.

[0050] It should be understood that the composition of the N steel pieces in S110 specifically refers to the various chemical components contained in the steel. For example, if all N steel pieces are Q235 steel, where Q represents the yield strength of the steel, i.e., the stress resisting slight plastic deformation, and 235 represents the ability to resist slight plastic deformation, the composition of this type of steel includes carbon, silicon, manganese, phosphorus, and sulfur. The specifications of the N steel pieces specifically include the length, width perpendicular to the roller conveyor direction, and thickness in the vertical direction of each steel piece when placed horizontally on the roller conveyor. Each of the N steel pieces has the same specifications, meaning that the length, width, and thickness of each steel piece are identical. The uses of the N steel pieces include, for example, the fabrication of metal structural components in construction, boilers, ships, bridges, or other engineering projects, or in the manufacture of metal structural components for automobiles and aerospace.

[0051] For example, such as Figure 2 A schematic diagram of steel specifications is provided. (For example...) Figure 2 As shown, the first steel bar is placed horizontally on a roller conveyor, which transports the first steel bar in the direction indicated by the arrow (the running direction of the roller conveyor). The specifications of the first steel bar include its length in the running direction of the roller conveyor, its width perpendicular to the running direction of the roller conveyor, and its thickness in the vertical direction when the first steel bar is placed horizontally on the roller conveyor. Figure 2 As shown.

[0052] S120, the controller determines the first process flow of N steel pieces based on their composition, specifications and uses. The first process flow includes heat treatment, packaging, weighing and warehousing.

[0053] It should be understood that the specifications and uses of steel determine the performance that steel needs to achieve, the metallographic structure of steel guarantees the performance that steel needs to achieve, and the composition and processing of steel determine the metallographic structure. Therefore, the processing flow of steel is determined according to the composition, specifications, and uses of the steel, and the processing flow includes various processes.

[0054] Optionally, the first process in S120 includes at least one of shot blasting, straightening, or welding.

[0055] To be understood, shot blasting is a process that uses a shot blaster to propel steel shot onto the surface of steel, removing dirt, oxides, rust, and corrosion, while also increasing the surface roughness of the steel. Straightening refers to the process of using a straightening machine to treat steel with varying degrees of curvature to obtain steel with better straightness. Welding is the process of joining metal workpieces together using methods such as heating or applying pressure.

[0056] Optionally, the heat treatment process in S120 includes at least one of normalizing, quenching, tempering, or annealing.

[0057] It should be understood that normalizing is a heat treatment process that refines the grains and homogenizes the distribution of carbides in steel. For some large or complex-shaped parts, normalizing can often replace quenching and tempering. Quenching is a process used to reduce or eliminate internal stress in steel, which can improve the hardness and wear resistance of metal workpieces, and improve the ductility or toughness of steel. Quenched parts should be tempered promptly. Through the combination of quenching and tempering, the desired mechanical properties can be obtained. Tempering is a heat treatment process that enhances the atomic mobility in steel, allowing the atoms of iron, carbon, and other alloying elements in the steel to diffuse more quickly, achieving atomic rearrangement and recombination, and stabilizing the microstructure of the steel. Tempering can improve strength and plasticity. Annealing is a heat treatment process that can reduce the strength of steel, improve machining performance, reduce residual internal stress, reduce deformation and crack tendency, optimize crystal structure, adjust microstructure, and eliminate microstructural defects.

[0058] Optionally, S120 includes: the controller determining at least one process for the N steel pieces based on their composition, specifications, and intended use; the controller sequencing the at least one process to determine the first process flow for the N steel pieces; wherein the at least one process includes at least one of a heat treatment process, a packaging process, a weighing process, or a warehousing process.

[0059] Optionally, the steel specifications include the following steel thicknesses: thin steel: 0.2-4mm, medium steel: 4-20mm, thick steel: 20-60mm, and extra-thick steel: >60mm.

[0060] For example, N pieces of steel are all NM550 steel, where NM refers to wear resistance and 550 is the hardness value, indicating the wear resistance of the steel. This type of steel is composed of carbon, silicon, manganese, phosphorus, sulfur, molybdenum, chromium, and nickel. The dimensions of the N pieces of steel are 1500mm * 3.00mm * 8000mm, and their purpose is for high-strength structural components in wear-resistant applications. Because this steel is thin, it is prone to deformation during heat treatment, requiring a straightening process. Since the steel is used for wear-resistant and high-strength structural components, a quenching and tempering process is employed in the heat treatment process to give the steel high wear resistance and good strength. Therefore, at least one process for NM550 steel includes straightening, quenching, and tempering, followed by packaging, weighing, and warehousing. Therefore, the process flow for NM550 steel after cross-cutting is: quenching - tempering - straightening - packaging - weighing - warehousing.

[0061] Optionally, after S120, the method further includes: the controller acquiring the composition, specifications, and uses of the transversely cut M steel blocks, wherein each of the M steel blocks has the same composition, specifications, and uses, and at least one of the composition, specifications, and uses of each of the M steel blocks differs from that of each of the N steel blocks; the controller determining the second process flow of the M steel blocks based on the composition, specifications, and uses of the M steel blocks, wherein the first process flow and the second process flow are different.

[0062] It should be understood that the composition, specifications, and use of each steel piece in M ​​steel pieces differ from, at least in one of the composition, specifications, and uses of each steel piece in N steel pieces, which can include the following situations: 1) The composition of each steel piece in M ​​steel pieces is the same as that of each steel piece in N steel pieces, the specifications of each steel piece in M ​​steel pieces are the same as those of each steel piece in N steel pieces, but the uses of each steel piece in M ​​steel pieces are different from those of each steel piece in N steel pieces; 2) The composition of each steel piece in M ​​steel pieces is the same as that of each steel piece in N steel pieces, the specifications of each steel piece in M ​​steel pieces are different from those of each steel piece in N steel pieces, but the uses of each steel piece in M ​​steel pieces are the same as those of each steel piece in N steel pieces; 3) The composition of each steel piece in M ​​steel pieces is different from those of each steel piece in N steel pieces; 4) The composition of each piece of steel in M ​​pieces is the same as that of each piece of steel in N pieces; the composition of each piece of steel in M ​​pieces is different from that of each piece of steel in N pieces; the composition of each piece of steel in M ​​pieces is different from that of each piece of steel in N pieces; the use of each piece of steel in M ​​pieces is different from that of each piece of steel in N pieces; 5) The composition of each piece of steel in M ​​pieces is different from that of each piece of steel in N pieces; the composition of each piece of steel in M ​​pieces is the same as that of each piece of steel in N pieces; the use of each piece of steel in M ​​pieces is the same as that of each piece of steel in N pieces.

[0063] For example, consider two steel pieces with the same composition and purpose but different specifications, but different process flows determined by the controller: N pieces of steel are all second-grade steel, composed of carbon, silicon, manganese, phosphorus, and sulfur, with dimensions of 1500mm * 3.00mm * 8000mm. This second-grade steel is used to manufacture process steel, such as punch material. M pieces of steel are all third-grade steel, composed of carbon, silicon, manganese, phosphorus, and sulfur, with dimensions of 1500mm * 63.00mm * 8000mm. This third-grade steel is also used to manufacture process steel, such as punch material. Since the second-grade steel is only 3mm thick, it is considered thin and prone to deformation during heat treatment, requiring a straightening process. The third-grade steel, however, is 63mm thick, making it extra-thick and not deformable during heat treatment, thus eliminating the need for straightening. Therefore, the process flow for the second-grade steel includes straightening, while the process flow for the third-grade steel does not. Therefore, the process flow for the second steel product is different from that for the third steel product.

[0064] For example, two steel pieces have the same composition and specifications but different uses, and the process flow determined by the controller is different: N pieces of steel are all fourth-grade steel, whose composition includes carbon, silicon, manganese, phosphorus, sulfur, molybdenum, chromium, and nickel. The specifications of the fourth-grade steel are 1500mm*3.00mm*8000mm, and its use is for wear-resistant and easily damaged parts on dump trucks in the humid and hot environment of southern China. M pieces of steel are all fifth-grade steel, whose composition includes carbon, silicon, manganese, phosphorus, sulfur, molybdenum, chromium, and nickel. The specifications of the fifth-grade steel are 1500mm*3.00mm*8000mm, and its use is for wear-resistant and easily damaged parts on dump trucks in the dry and cold environment of northern China. Because the fourth type of steel is used in the humid and hot environment of the south, it is less prone to cracking during heat treatment; while the fifth type of steel is used in the dry and cold environment of the north, it is prone to cracking during heat treatment. Therefore, the quenching temperature of the fifth type of steel must be lower than that of the fourth type of steel to improve its ductility or toughness and prevent cracking. Thus, the process flow for the fourth and fifth types of steel differs.

[0065] It should be understood that the above are merely examples of situations where steel with the same composition but different specifications and uses has different process flows, or where steel with the same composition but different uses has different specifications has different process flows.

[0066] S130, the controller determines the positions for each process in the first process flow and the number of personnel required for each position.

[0067] Optionally, S130 includes: the controller determining, in a first list, the positions of each process included in the first process flow and the number of personnel required for each position in each process, the first list including the positions of each process in multiple processes and the number of personnel required for each position in multiple processes, the multiple processes including the various processes included in the first process flow.

[0068] For example, Table 1, the first list, specifically provides the positions for each process in multiple processes and the number of personnel required for each position in multiple processes.

[0069] Table 1 First List

[0070] Quenching One person for feeding materials, one main operator, and one assistant operator. Tempering 1 person for loading materials, 2 people for hoisting materials, and 1 person for stacking pallets. Straightening Straightening 1 person Zheng Huo One person for feeding materials, one main operator, and one assistant operator. annealing One person for feeding materials, one main operator, and one assistant operator. Pack Pack for 1 person weighing Weighing 1 person Warehousing One person was added to the inventory.

[0071] The process flow of NM550 steel after cross-cutting, determined by the controller using S120, is as follows: quenching - tempering - straightening - packaging - weighing - warehousing. Based on the saved first list, the controller determines the positions and required personnel for each process in this flow: 1 person for loading, 1 main operator, and 1 assistant operator during quenching; 1 person for loading, 2 people for hoisting, and 1 person for stacking during tempering; 1 person for straightening; 1 person for packaging; 1 person for weighing and 1 person for warehousing.

[0072] S140, the controller obtains the amount of steel that the heat treatment process included in the first process can process per unit time.

[0073] Optionally, the heat treatment furnace is used to handle the heat treatment process, and the roller conveyor is used to sequentially transport N steel pieces into the heat treatment furnace. The distance between two adjacent steel pieces on the roller conveyor is a preset value. The specifications of each steel piece include the length of each steel piece in the roller conveyor running direction when it is placed horizontally on the roller conveyor. The length of the heat treatment furnace in the roller conveyor running direction is the first length.

[0074] For example, such as Figure 3 As shown, N is 2, and the two steel pieces on the roller conveyor are sequentially transported one by one to the heat treatment furnace according to the running direction of the roller conveyor; the distance A between two adjacent steel pieces on the roller conveyor is a preset value; the length of the heat treatment furnace in the running direction of the roller conveyor is the first length B.

[0075] Optionally, the controller obtains the number of steel pieces that the heat treatment process can handle per unit time in the first process flow, including: the controller determining a first number of steel pieces currently being processed by the heat treatment furnace based on a preset value, the length of each steel piece in the roller conveyor running direction when placed horizontally on the roller conveyor, and a first length; the controller determining the time required for each steel piece to undergo the heat treatment process based on the speed of the roller conveyor and the length of each steel piece in the roller conveyor running direction when placed horizontally on the roller conveyor; and the controller determining the number of steel pieces that the heat treatment process can handle per unit time based on the first number and the time required for each steel piece to undergo the heat treatment process.

[0076] Optionally, the controller determines the first quantity of steel currently being processed by the heat treatment furnace based on a preset value, the length of each piece of steel in the running direction of the roller conveyor when it is placed horizontally on the roller conveyor, and a first length, including: the controller determines the first distance between the tails of two adjacent pieces of steel in the running direction of the roller conveyor based on the preset value and the length of each piece of steel in the running direction of the roller conveyor when it is placed horizontally on the roller conveyor; the controller determines the first quantity of steel currently being processed by the heat treatment furnace based on the first distance and the first length.

[0077] Optionally, the controller determines the first distance between the tails of two adjacent steel pieces in the running direction of the roller conveyor based on a preset value and the length of each steel piece in the running direction of the roller conveyor when it is placed horizontally on the roller conveyor, including: the controller determines the first distance as the sum of the preset value and the length of each steel piece in the running direction of the roller conveyor when it is placed horizontally on the roller conveyor.

[0078] Optionally, the controller determines the first quantity of steel currently being processed by the heat treatment furnace based on the first spacing and the first length, including: the controller determining the ratio of the first length to the first spacing as the first quantity of steel currently being processed by the heat treatment furnace.

[0079] Optionally, the controller determines the time required for each piece of steel to undergo heat treatment based on the speed of the roller conveyor and the length of each piece of steel in the direction of roller conveyor travel when it is placed horizontally on the roller conveyor. This includes: the controller determining the ratio of the length of each piece of steel in the direction of roller conveyor travel when it is placed horizontally on the roller conveyor to the speed of the roller conveyor as the time required for each piece of steel to undergo heat treatment.

[0080] Optionally, the controller determines the number of steel pieces that the heat treatment process can process per unit time based on the first quantity and the time required for the heat treatment process of each piece of steel, including: the controller determines the time required for the heat treatment process of the first quantity of steel by multiplying the first quantity by the time required for the heat treatment process of each piece of steel; the controller determines the number of steel pieces that the heat treatment process can process per unit time by the ratio of the unit time to the time required for the heat treatment process of the first quantity of steel.

[0081] In the above scheme, the heat treatment furnace has a certain length and can simultaneously heat treat multiple pieces of steel. Therefore, in this scheme, the controller determines the first quantity of steel currently being processed by the heat treatment furnace, which is the quantity of steel that the heat treatment furnace itself can accommodate, based on preset values, the length of each piece of steel in the direction of roller movement when placed horizontally on the roller conveyor, and the first length. The controller then determines the time required for each piece to undergo heat treatment based on the speed of the roller conveyor and the length of each piece of steel in the direction of roller movement when placed horizontally on the roller conveyor. The controller then determines the time required for the heat treatment furnace to heat treat the first quantity of steel at a time, based on the time required for each piece to undergo heat treatment and the quantity of steel that the heat treatment furnace itself can accommodate. Finally, the controller determines the quantity of steel that the heat treatment process can process per unit time based on the unit time and the time required to heat treat the first quantity of steel.

[0082] For example, the heat treatment process is normalizing, with a preset length of 500mm. Each piece of steel, when placed horizontally on the roller conveyor, has a length of 8000mm in the roller conveyor's running direction. The normalizing heat treatment furnace has a first length of 72m in the roller conveyor's running direction, and the roller conveyor speed is 5000mm / min. The controller divides 72000mm (72m) by 8500mm (the sum of 8000mm and 500mm) to obtain the first number of steel pieces currently being processed by the heat treatment furnace, which is 8 pieces. The controller divides 8500mm (the sum of 8000mm and 500mm) by 5000mm / min to obtain the time required for the heat treatment process of each piece of steel, which is 1.7min. The controller multiplies 8 by 1.7 to obtain the time required for the heat treatment process of the first number of steel pieces, which is 13.6min. The controller divides 60 (min) by 13.6 to obtain the number of steel pieces that the heat treatment process can process per unit time, which is 4 pieces, i.e., the number of steel pieces that the normalizing process can process in one hour.

[0083] Optionally, the heat treatment process includes a quenching process and a tempering process, and the heat treatment furnace is a heat treatment furnace for both the quenching and tempering processes.

[0084] It should be understood that when the heat treatment process includes a quenching process and a tempering process, the heat treatment furnace is a heat treatment furnace in which the quenching process and the tempering process are connected.

[0085] S150, the controller determines the time required for the heat treatment process of N steel pieces based on the quantity of steel that can be processed per unit time and the total quantity of steel N. The production plan for N steel pieces includes the positions of each process in the first process flow, the number of personnel required for each position in each process, and the time required for the heat treatment process of N steel pieces.

[0086] Optionally, S150 includes: the controller determining the ratio of the total number of steel N to the number of steel that the heat treatment process can process per unit time as the time required to perform the heat treatment process on N pieces of steel.

[0087] For example, if the total number of steel pieces N is 400 pieces, and the heat treatment process can process 20 pieces / min of steel pieces per unit time, then the time required to heat treat N pieces of steel is 2000 pieces / (20 pieces / min), or 20 minutes.

[0088] Optionally, after S150, the controller controls the steel processing equipment to process the N steel pieces according to the production plan of the N steel pieces.

[0089] Figure 4 A schematic diagram of the structure of the controller for a confirmed production plan provided in this application embodiment is shown below. Figure 4 As shown, the controller includes:
