[0050] Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings.

[0051] Various structural schematic diagrams according to embodiments of the present application are shown in the accompanying drawings. These figures are not drawn to scale, and some details are magnified and some details may be omitted for the purpose of clear expression. The shapes of various regions and layers shown in the figures and the relative sizes and positional relationships therebetween are only exemplary, and may deviate in practice due to manufacturing tolerances or technical limitations, and those skilled in the art may further design regions / layers with different shapes, sizes, and relative positions according to actual needs.

[0052] In order to better understand the above-mentioned technical scheme, the above-mentioned technical scheme will be described in detail below in combination with specific implementation methods. It should be understood that the embodiments of the present disclosure and the specific features in the embodiments are detailed descriptions of the technical scheme of the present application, rather than limitations on the technical scheme of the present application. In the absence of conflict, the embodiments of the present application and the technical features in the embodiments can be combined with each other.

[0053] As competition among steel companies intensifies, the rapid turnover and sales of surplus steel plates have become an important part of corporate profitability. With the continuous generation of surplus steel plates, unsold surplus steel plates are piled up in inventory. High inventory operation has brought a large amount of capital occupation to the company, making it difficult for the company to operate.

[0054] In order to reduce the inventory pressure of surplus steel plates, they need to be sold. At the same time, in order to avoid quality disputes, the surplus steel plates are downgraded to the lowest grade and sold in the form of spot goods. The downgrading of surplus steel plates directly affects the sales price. At the same time, selling them in the form of spot goods further reduces the price, which will cause serious economic losses.

[0055] In view of this, this application provides a steel production management method, please refer to Figure 1 , Figure 1 The flow chart of the steel production management method in the embodiment of the present application includes:

[0056] S101. Obtain order information, where the order information includes specification indicators, steel type indicators, steel grade indicators, performance grade indicators, and demand quantity of target steel.

[0057] S102. Compare the inventory information with the order information to determine the quantity of inventory steel materials that matches the order information. The inventory information includes specifications, steel types, steel grade, and performance grade of the inventory steel materials.

[0058] S103. Determine the production volume of the target steel material according to the demand volume of the target steel material and the quantity of the stock steel material matching the order information.

[0059] The steel production management method provided in the embodiment of the present application compares the inventory steel with the order in terms of specifications, steel type, steel grade, and performance, and sells the inventory steel that matches the order demand indicators under the order, thereby reducing inventory pressure, increasing benefits, reducing production pressure, and improving supply efficiency.

[0060] It is understandable that the surplus steel plates with the same steel grade are matched with the contract and put on the order, and sold as genuine products. Since the contract stipulates the specifications and performance of the steel, it is rare that the surplus steel plates are completely consistent with the contract requirements. Therefore, the volume of surplus steel plates sold by this method is not high.

[0061] The following specific embodiments are used to describe in detail the technical solution of the present application and how the technical solution of the present application solves the above technical problems. The following specific embodiments can be implemented independently or in combination with each other, and the same or similar concepts or processes may not be described in detail in some embodiments.

[0062] It is understandable that the comparison between inventory steel and order information requires a unified basic standard, so it is necessary to collect and organize the general information of steel to form a steel information database. Figure 2 As shown, before obtaining order information, it also includes:

[0063] S201. Classify multiple steels according to steel types to obtain multiple steel type numbers. The multiple steels here refer to multiple steels with different grades. Each steel usually has a unique and fixed grade. The grade is a combination of Chinese phonetic letters, chemical element symbols and Arabic numerals to indicate the name, use, characteristics and process of the steel. Here, the steels are classified and numbered according to steel types. Each steel type number includes multiple steels belonging to the same steel type category.

[0064] S202. For each of the plurality of steel grade numbers, classify the steel material corresponding to the steel grade number according to the steel grade to obtain a plurality of steel grade numbers.

[0065] Each steel grade number includes multiple types of steel belonging to the same steel category, and each type of steel has a different grade. Here, the steel is classified and numbered according to the steel grade, and the steel is further classified.

[0066] S203, for each of the multiple steel grade numbers, classify the steel corresponding to the steel grade number according to the performance grade to obtain multiple performance grade numbers.

[0067] Each steel grade number corresponds to steels of multiple performance levels. The information of each grade of steel is further refined according to performance classification.

[0068] S204. For each of the multiple steel materials, the brand of the steel material is associated with the steel type number, steel type grade number and performance grade number of the steel material to form a steel material information database.

[0069] The properties of steel include tearing performance and impact resistance, which are represented by grades. The higher the grade number, the better the performance. Exemplarily, for each of a plurality of steel grade numbers, the steel corresponding to the steel grade number is classified according to the tearing grade to obtain a plurality of tearing grade numbers; and the steel corresponding to the steel grade number is classified according to the impact resistance grade to obtain a plurality of impact resistance grade numbers.

[0070] S205, according to the steel information database and the brand of the stock steel, determine the steel type number, steel type grade number, and performance grade number of the stock steel, and associate the brand, steel type number, steel type grade number, performance grade number, and quantity of the stock steel to form the stock information. Specifically, the operation is to associate the brand, steel type number, steel type grade number, tear grade number, impact grade number, and quantity of the stock steel to form the stock information.

[0071] At this point, the operations of S201 to S204 above classify each brand of steel according to steel type, steel grade, and performance grade. Based on this information, various information of the stock steel can be easily obtained.

[0072] In view of the above operations of S201 to S204, in some optional implementations, the operation of executing S101 specifically includes: determining the steel type number of the target steel as the steel type index of the target steel according to the steel information database and the brand of the target steel, determining the steel grade number of the target steel as the steel grade index of the target steel, and determining the performance grade number of the target steel as the performance grade index. The brand, steel type index, steel grade index, and performance grade index of the target steel are associated with the specification index and quantity of the target steel to form order information.

[0073] In view of the above operations, in some optional implementations, the operation of performing S102 specifically includes:

[0074] Compare the inventory information with the order information to determine the quantity of inventory steels whose steel type numbers are the same as the steel type indicators of the target steel, whose specifications are greater than or equal to the specification indicators of the target steel, whose steel grade numbers are greater than or equal to the steel grade indicators of the target steel, and whose performance grade numbers are greater than or equal to the performance grade indicators of the target steel.

[0075] For example, in the first step, the steel grade number of the stock steel is compared with the steel grade index of the target steel, and the stock steel with the same steel grade number and steel grade index as the target steel is selected. The goal of this operation is to select steel from the stock steel whose steel grade matches the steel grade of the target steel. If the steel grade of the stock steel is inconsistent with the steel grade of the target steel, it is completely impossible to place an order for sale.

[0076] For example, if the order requires that the target steel type is ship plate, then the material that can be placed for sale in the inventory must be ship plate, and cannot be pipeline steel or composite plate.

[0077] The second step is to compare the specifications of the stock steels whose steel grade numbers are the same as the steel grade indicators of the target steels with the specifications of the target steels, and screen out the stock steels whose specifications are greater than or equal to the specifications of the target steels.

[0078] The purpose of this operation is to select steel with size specifications greater than or equal to the target size specifications required by the target steel from the inventory steel of matching steel types. If the size of the inventory steel is smaller than the target steel requirement, it cannot be sold at all. If the size of the inventory steel is larger, it can be sold after further processing according to the specification indicators.

[0079] The third step is to compare the steel grade numbers of the screened inventory steels whose specifications are greater than or equal to the specification indicators of the target steels with the steel grade indicators of the target steels, and screen out the inventory steels whose steel grade numbers are greater than or equal to the steel grade indicators of the target steels.

[0080] The purpose of this operation is to further select steels with steel grades that match the order requirements from the inventory steels with matching steel types and specifications. Specifically, it is to select steels with steel grades greater than or equal to the steel grades required by the order. If the steel grade of the inventory steel is lower than the steel grade index of the target steel, it cannot be placed for sale at all, which will lead to the problem of passing inferior products off as good ones and cause disputes.

[0081] The fourth step is to compare the performance grade numbers of the screened out stock steels whose steel grade numbers are greater than or equal to the steel grade index of the target steel with the performance grade index of the target steel, screen out the stock steels whose performance grade numbers are greater than or equal to the performance grade index of the target steel, and determine the number of the screened out stock steels whose performance grade numbers are greater than or equal to the performance grade index of the target steel.

[0082] The purpose of this operation is to select steel with medium performance level that matches the order requirements from steel with steel type and steel grade that matches the order requirements. Specifically, it is to further select the stock steel with performance level higher than or equal to the performance level index of the target steel. If the performance level of the stock steel is lower than the performance level index of the target steel, it cannot be placed for sale at all, which will lead to the problem of passing inferior products off as good ones and cause disputes.

[0083] In some optional implementations, the order information further includes the trimming shape index and the flaw detection grade index of the target steel material, and the inventory information further includes the trimming shape and the flaw detection grade of the inventory steel plates;

[0084] After executing the operation of S102, the method further includes:

[0085] The trimming shape of the stock steel that matches the order information is compared with the trimming shape index of the target steel. If they do not match, it is determined that the trimming shape of the non-matching stock steel is processed according to the trimming shape index. Also, the flaw detection grade of the stock steel that matches the order information is compared with the flaw detection grade index of the target steel. If they do not match, it is determined that the non-matching stock steel is subjected to flaw detection according to the flaw detection grade index.

[0086] The trimming shapes of steel include rolled edge, flame trimming edge, shear edge, etc. The rolled edge has a rough feel and is broken under a magnifying glass. Some of the edges with a high processing rate can be seen with the naked eye. The advantage is that the edge is flat. The flame trimming feels smoother, but there are unevenness, and the edge thickness tolerance varies. The width tolerance is large, there are concave and convex cutting tumors, the edge is dense, and there is no crack. The shear edge is neat and smooth, with small deformation of thickness and width, and good tolerance consistency. The disadvantage is that there are shear burrs.

[0087] If the order information specifies the trimming shape of the target steel, it is also necessary to determine whether the inventory steel matches the order requirements. If not, the trimming of the inventory steel also needs to be further processed.

[0088] Similarly, the flaw detection level of steel is divided into level 1, level 2 and level 3, and each level has differences in detection accuracy, methods and requirements. Level 1 is suitable for surface defect detection, level 2 can detect smaller internal defects, and level 3 is for the most subtle defects. The choice of flaw detection level depends on the specific needs and steel plate quality requirements.

[0089] If the order information specifies the flaw detection level of the target steel, and the inventory steel does not meet the flaw detection level required by the order, further flaw detection testing of the inventory steel is required.

[0090] The steel production management method provided in the embodiment of the present application is described below with reference to an example, which does not constitute a limitation on the embodiment of the present application. The following embodiments can be combined with each other, and the same or similar concepts or processes will not be described in detail.

[0091] The steel production management method provided in the embodiment of the present application can be applied to the sale of surplus steel plates with orders placed across steel grades, and is used to increase the probability of surplus steel plates being placed for sale with formal orders. The specific operations are as follows:

[0092] S1) Establish a steel classification dictionary, i.e. (steel information database): classify the grades according to different steel grades, and classify the grades under the same steel grade category according to different levels. At the same time, classify the grades according to the Z-direction grade (tear grade) and impact grade according to the performance differences required by users. It is clear whether a certain grade is allowed to be linked to other grades in the same classification, and whether a certain grade is allowed to be linked to other grades in the steel grade classification.

[0093] For example, the steel classification dictionary is as follows: Figure 3 , 4 As shown, Figure 3 This is an example of some information in the steel classification dictionary in the embodiment of this application Figure 1 , Figure 4 This is an example of some information in the steel classification dictionary in the embodiment of this application Figure 2 .from Figure 3 , 4 It can be seen that steels belonging to different steel categories belong to different steel categories (steel category numbers). Under the same steel category, there are multiple sub-categories (steel grade numbers), as well as Z-axis grade numbers (tear performance numbers) and impact grades (impact grade numbers).

[0094] S2) Capture of residual steel plate information: First, the information of residual steel plates that are not placed in the warehouse is captured, such as steel plate number, steel type, product specification code, material thickness, width, length, nominal weight, actual weight, trimming status, current weighing method, warehouse area, stacking position, flaw detection standard, surface inspection standard, actual thickness, historical steel type, currently determined defects, surface inspection results, yield strength ratio, defect classification, etc.; then special steel plates are discharged, such as residual composite plates, residual materials with agreed surface quality, residual materials with unqualified performance, and residual materials in a certain warehouse area.

[0095] S3) Contract information capture: Capture all contract information in the system, such as contract number, contract number, steel type, required thickness, required minimum width, maximum width, minimum length, maximum length, weighing method, shear state, contract type, flaw detection level, lower and upper limits of allowable thickness deviation, POC, length, allowable length deviation, yield strength ratio, contract notch weight, contract status, etc.; then exclude some contracts, such as contracts of QZA, QBA in nature, contracts with unproduced weight of 0, etc.

[0096] S4) Order matching: During the matching process, the steel plate is mainly verified against the steel type, trimming status, flaw detection requirements, specifications (size) and other information in the contract. Except for the steel type, other information requirements must be met.

[0097] If it does not meet the requirements, the corresponding treatment process needs to be added to the steel plate. For example, if the flaw detection requirement is required, additional flaw detection needs to be performed on the remaining steel plate. Determine whether further processing is required. If further processing is not possible, the production system will generate according to the shortage.

[0098] For example, there are 4 matching scenarios for different steel types: ① The current steel type is matched or plate grouped, that is, when the steel type and specification of the steel plate meet the contract requirements, the order is placed directly; if the steel plate specification is larger than the contract specification, the plate group is required to cut the steel plate and place an order, and a prompt is given. Among them, the current steel type is matched, which means that the parameters of the residual steel plate match the order, and the order can be placed directly for sale, and the plate group means that the residual steel plate can be placed for sale after further processing.

[0099] ② The existing steel grade is matched or grouped across steel grades. That is, if the steel grade of the steel plate can meet the contract steel grade by downgrading, the match is successful, and a prompt is given to change the steel grade; if the steel plate specification is larger than the contract specification, the steel plate needs to be grouped to place an order for cutting, and a prompt is given;

[0100] ③ The original steel grade is matched or grouped. If the original steel grade of the steel plate is consistent with the contract steel grade, the match is successful, and a prompt is given to change the steel grade. That is, in the production system, the grade of the surplus steel plate to be sold is reduced to the same as the order requirement, so that the production system can match it conveniently. If the steel plate specification is larger than the contract specification, the steel plate needs to be grouped and cut and placed, and a prompt is given;

[0101] ④ If the original steel grade is matched or grouped across steel grades, and the original steel grade of the steel plate can meet the contract steel grade by downgrading, the match is successful, and a prompt is given to change the steel grade; if the steel plate specification is larger than the contract specification, the steel plate needs to be grouped for cutting and placing an order, and a prompt is given.

[0102] S5) Dynamically reduce steel production plan: According to the matching results of surplus steel plates and contracts, dynamically reduce the steel production plan to avoid over-investment in contracts.

[0103] The above operations include the design of steel classification dictionary and matching rule design, the details are as follows:

[0104] Design of steel classification dictionary

[0105] In order to maximize the probability of the surplus steel plates being sold as formal orders and to avoid quality disputes, a steel classification dictionary was designed, such as Figure 1 As shown in the figure, column A shows the grade of each steel type, column B specifies whether the steel plate of each grade is allowed to be linked to other grades in the same classification, and column C specifies whether each grade is allowed to be linked to other grades in the same classification. The grades in column A are classified according to different steel types, such as Figure 3 In column D, the same number in column D represents a major category of steel. Then, the grades under the same major category of steel are classified according to different steel grades, such as Figure 3 In the E column, the same number in the E column represents the same steel grade. Then, according to the performance differences required by the user for the grade, the Z-direction grade and impact grade are classified, such as Figure 3 Middle F and G columns.

[0106] (2) Matching rule design

[0107] This method includes the design of a matching rule, the specific rules are as follows:

[0108] ① Figure 3 Column B is mainly used for screening when matching steel plates. For example, if the steel plate grade is AB / EQ63 Z35, this steel plate is prohibited from being included in the contract of other grades of the same classification, that is, this steel plate is prohibited from being revived.

[0109] ② Figure 3 Column C is mainly used for screening during contract matching. For example, if the contract grade is AB / EQ63Z35, this steel plate also prohibits the remaining steel plates with the same classification grade from being matched to this contract.

[0110] ③ When the steel plate brand is AB / FH40 Z35, which is the 9th row of column A in the dictionary, according to the rules of ① and ②, the steel plate of this brand is allowed to be listed and sold under other brands in the same classification. According to the Z-direction grade in column F, the number corresponding to AB / FH40 Z35 is 3, so it can be downgraded normally to the brand corresponding to the number 2 or 0 for resurrection, that is, it can be downgraded to AB / FH40 Z25 or AB / FH40 for sale, thereby increasing the probability of matching the steel plate with the contract.

[0111] Another example Figure 4 The three types of steel, namely BV / AH32, BVAH32 Z25 and BVWAH32 Z35, belong to the same category under the same steel category, and are allowed to be listed on other brands under the same category for sale, and other brands of the same category are also allowed to be listed. For example, when an order requires BV / AH32 steel plates, stock steel plates with higher Z-level grades of BVAH32Z25 or BVAH32 Z35 can be listed in the order for downgrade sales. When an order requires BVAH32 Z25 steel plates, stock steel plates with higher Z-level grades of BVAH32 Z35 can be listed in the order for downgrade sales.

[0112] It is understandable that when an order requires BVAH32 Z35 grade steel plates, stock steel plates with lower Z-grade grades of BV / AH32 and BVAH32 Z35 cannot be included in the order for upgrade sales.

[0113] The steel production management method provided in the embodiment of the present application is adopted and applied to the sales of surplus steel plates with cross-grade orders. A classification dictionary is established for steel plate grades and brands, and four types of order matching are carried out based on the dictionary, namely, matching or grouping plates with current steel grades, matching or grouping plates with current steel grades across steel grades, matching or grouping plates with original steel grades, and matching or grouping plates with original steel grades across steel grades, so as to maximize the sales volume of surplus steel plates with futures orders. Through this method, the volume of surplus steel plates with orders can be increased by about 300 pieces / month, the spot sales volume can be reduced, and considerable economic benefits can be created.

[0114] Based on the same inventive concept, the present application embodiment also provides a steel production management device, please refer to Figure 5 , Figure 5 This is a wireframe diagram of a steel production management device in an embodiment of the present application. The steel production management device 500 includes:

[0115] The order information acquisition unit 501 is used to acquire order information, which includes specification indicators, steel type indicators, steel grade indicators, performance grade indicators and demand quantity of the target steel.
