Obviously, the described embodiments are only some of the embodiments of the present application, but not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present application.

[0025] In the production process of steel products, accurate resource and energy consumption and recovery cannot be obtained due to lack of metering instruments or inaccurate metering instruments, and energy power and auxiliary material costs in additional costs cannot be accurately calculated.

[0026] The traditional cost accounting method is often based on the experience of experienced personnel in the business department to give a theoretical cost composition, and the total cost is calculated by adding these theoretical cost compositions, but the total cost cannot reflect the characteristics of energy and auxiliary material consumption of different products, and the cost accounting is relatively inaccurate.

[0027] Therefore, the steel product cost accounting method and device provided by the embodiments of the present application can obtain cost-related data in the production process of steel products, clean the cost-related data based on a pre-set cleaning strategy, obtain target cost-related data, determine the main raw material cost and the additional cost based on the target cost-related data, and the additional cost is obtained by apportioning the physical quantity, form the total cost based on the main raw material cost and the additional cost, determine the quality cost and restore the quality cost to the total cost to obtain the standard cost, keep the input and output consistent in the production process of steel products based on the standard cost, and obtain the actual cost. In this way, by determining the main raw material cost, the additional cost and the quality cost, and apportioning the additional cost, the characteristics of energy and auxiliary material consumption of different products can be reflected, and the accuracy of cost accounting can be improved.

[0028] In order to facilitate the understanding of the embodiments, first, a steel product cost accounting method disclosed by the embodiments of the present application will be described in detail.

[0029] Embodiment 1

[0030] The embodiments of the present application provide a steel product cost accounting method, Figure 1 A flowchart of the steel product cost accounting method provided by the embodiments of the present application is shown in FIG. 1. Figure 1 As shown in the figure, the steel product cost accounting method can include the following steps:

[0031] Step S101, obtaining cost-related data in the production process of steel products.

[0032] The cost-related data can be obtained by collecting and integrating data in the system, and the system can include a cost accounting system, a manufacturing management system, a sales management system, a manufacturing execution system of each production unit, and a financial shared system, and the system includes various resource and energy measurement data consumed and recovered in the steel product production process and various labor and manufacturing costs for assisting production.

[0033] In step S102, the cost-related data is cleaned based on a pre-set cleaning strategy to obtain target cost-related data.

[0034] The cost-related data can be verified for accuracy, consistency, completeness, and timeliness to determine data with data quality problems, and the data with data quality problems is cleaned.

[0035] In step S103, the main raw material cost and the additional cost are determined based on the target cost-related data.

[0036] The additional cost is obtained by apportioning physical quantities. The additional cost includes four cost items: energy power cost, auxiliary material cost, manufacturing cost, and labor cost, and each cost item is composed of multiple cost subjects, and different cost subjects are further divided into different types.

[0037] The main raw materials of the steel product include molten iron, scrap steel, alloy, and semi-finished raw materials of each process, etc. By statistical analysis of key indicators such as steel material and process yield rate according to different product dimensions, the main raw material cost can be obtained.

[0038] In actual application, the specific consumption, yield rate, and recovery rate data need to be corrected because the main raw material production control may not be stable during the historical production process.

[0039] The physical quantities can include area, length, time, temperature, etc. A series of apportioning coefficients can be determined based on different physical quantities to reflect the characteristics of energy and auxiliary material consumption of different products.

[0040] In step S104, the complete cost is formed based on the main raw material cost and the additional cost.

[0041] The complete cost is the sum of the main raw material cost and the additional cost.

[0042] In step S105, the quality cost is determined and the quality cost is reduced to the complete cost to obtain the standard cost.

[0043] The quality cost includes the rejudgment cost, the process waste cost, and the rework cost.

[0044] The quality cost is the sum of the rejudgment cost, the process waste cost, and the rework cost.

[0045] Wherein, the rejudgment cost is equal to the raw material cost before rejudgment minus the raw material cost after rejudgment; the quality cost includes the rejudgment cost, the process waste cost and the rework cost. The process waste refers to the loss quantity due to the quality reason; the rework cost refers to the rework due to the quality reason, such as the hot rolling balance, the cold rolling re-winding process and the like.

[0046] Step S106, based on the standard cost, the input and output in the steel product production process are kept consistent, and the actual cost is obtained.

[0047] Wherein, the cost calculation of each process is completed according to the steps S101-S106, and finally the complete cost standard of different steel products is formed. The calculation logic of the actual cost is similar to the standard cost, but the input and output of each process need to be consistent with the actual situation.

[0048] The steel product cost accounting method provided by the embodiment of the present application can obtain the cost related data in the steel product production process, clean the cost related data based on the pre-set cleaning strategy, obtain the target cost related data, determine the main raw material cost and the additional cost based on the target cost related data, the additional cost is obtained by apportioning the physical quantity, form the complete cost based on the main raw material cost and the additional cost, determine the quality cost and restore the quality cost to the complete cost to obtain the standard cost, keep the input and output in the steel product production process consistent based on the standard cost, and obtain the actual cost. In this way, by determining the main raw material cost, the additional cost and the quality cost, and apportioning the additional cost, the characteristics of different product energy and auxiliary material consumption are reflected, and the accuracy of cost accounting is improved.

[0053] ​The cost-related data can include: financial cost system expenses and auxiliary material consumption data, manufacturing management system and PES production performance and process design parameters, sales management system order product attributes, procurement management system main raw material and auxiliary material procurement prices, energy management system energy medium consumption and purchased energy information. The cost-related data can be used to construct a full-process traceable cost data model with smelting number, billet number and steel number as the primary key.

[0054] The data model with smelting number as the primary key is mainly used to gather cost-related data before continuous casting. The billet number is mainly used to gather cost-related data after continuous casting and before rolling. The steel number is mainly used to gather cost-related data after rolling. The steel number includes a set of steel numbers for full-process material tracking.

[0055] The cost-related data can be uniformly gathered into the enterprise data hub and stored in the hub as raw data, derived data and the like.

[0056] In step S202, the cost-related data is cleaned based on a pre-set cleaning strategy to obtain target cost-related data.

[0057] Specifically, the cost-related data is cleaned based on a pre-set cleaning strategy to obtain target cost-related data, which can include: verifying the cost-related data to determine abnormal data; performing missing value filling processing and / or abnormal value processing on the abnormal data based on the cleaning strategy to obtain the target cost-related data.

[0058] The abnormal data is data with data quality problems, which can be filled with missing values, processed with abnormal values, and restored with production system and cost system data to ensure the data quality of the cost-related data. For example, the hourly capacity of the production performance is abnormal, which needs to be corrected according to the actual characteristics of product production. The correction methods include but are not limited to taking the average value and the like.

[0059] In step S203, the main raw material cost and the additional cost are determined based on the target cost-related data.

[0060] The additional cost is obtained by apportioning physical quantities.

[0061] Specifically, the main raw material cost and the additional cost are determined based on the target cost-related data, which can include: determining the main raw material cost based on the historical actual production of the main raw material input-output data; dividing the additional cost into multiple cost items based on the target cost-related data; dividing the multiple cost items into different types of cost subjects; and apportioning the physical quantities based on the consumption characteristics of different cost subjects to determine the total cost and unit cost of each billet.

[0062] The main raw material cost is determined based on the historical actual production of main raw material input-output data, which can include: determining the main raw material cost based on the historical actual production of main raw material input-output data by the following formula: ; wherein S ji is the i-th raw material input of product j, P j is the yield of product j, U ji is the unit cost of the i-th raw material of product j; before determining the main raw material cost based on the historical actual production of main raw material input-output data, the method further comprises: correcting the cost factor in the historical actual production of main raw material input-output data to obtain a cost factor correction value by the following formula: ; wherein β is the cost factor, β max is the maximum value of the cost factor under normal production conditions, and β min is the minimum value of the cost factor under normal production conditions.

[0063] The historical actual production of main raw material input-output data can be dynamically adjusted, for example, the adjustment period is monthly, and the adjustment range is the historical data time range used to calculate the cost standard, so that the actual cost control level of the enterprise can be fully reflected.

[0064] The time value range of the input and output can be adjusted monthly, and multiple versions of the cost standard can be generated.

[0065] The allocation coefficient of each cost subject is composed of one or more process parameters, and there is a certain linear or nonlinear correlation between multiple process parameters. According to the correlation, a large amount of historical data is used for model training to form a cost allocation coefficient function of the jth cost subject .

[0066] Based on the consumption characteristics of different cost subjects, physical quantities are used for allocation processing to determine the total cost and unit cost of each billet, including: the cost allocation coefficient function is represented by the following formula ; wherein is the production process parameter of the i-th steel coil production process, and the production process parameter includes: furnace time, discharge temperature, steel coefficient, rolling time; the cost of the unit physical quantity is determined by the following formula: ; wherein, is the total cost of the vth cost subject in the hth month in the statistical period, is the physical quantity of the vth cost subject of the i-th steel coil in the statistical period; the total cost is determined by the following formula: ; the unit cost is determined based on the cost of the unit physical quantity and the total cost by the following formula: ; wherein T iis the weight of the current billet. Step S204, the total cost is formed based on the main raw material cost and the additional cost.

[0067] Specifically, the total cost is determined by the following formula: .

[0068] wherein, is the total cost, is the main raw material cost, is the additional cost.

[0069] Step S205, the quality cost is determined and the quality cost is reduced into the total cost to obtain the standard cost.

[0070] wherein, the quality cost can include: the rejudgment cost, the process waste cost and the rework cost.

[0071] Specifically, the quality cost is determined and the quality cost is reduced into the total cost to obtain the standard cost, including: the rejudgment cost is determined by the following formula: ; wherein, is the rejudgment cost, is the raw material cost before rejudgment, is the raw material cost after rejudgment; the process waste cost is determined by the following formula: ; wherein, is the process waste amount, is the raw material amount, is the unit cost of the raw material; the rework cost is determined by the following formula: ; wherein, is the rework cost of the A product in the i th process; the rejudgment cost, the process waste cost and the rework cost are added to obtain the quality cost ; the quality cost is reduced into the total cost to obtain the standard cost by the following formula: ; wherein, , is the total cost, is the quality cost, is the main raw material cost, is the additional cost.

[0072] Step S206, based on the standard cost, the input and output in the steel product production process are kept consistent to obtain the actual cost.

[0073] wherein, the calculation logic of the actual cost is similar to the calculation method of the standard cost, but the input and output of each process need to be consistent with the actual.

[0074] wherein, for the steel product, the type can include: casting billet, hot rolling, cold rolling, galvanizing, color coating, silicon steel, medium plate, bar and wire, profile and pipe, etc., which are not limited here.

[0075] Step S207, comparing the actual cost and the standard cost to analyze the production organization and the cost structure.

[0076] The actual cost is compared with the standard cost. By comparing the actual cost with the standard cost, the comparison of the same product in different cost subjects is formed, and the influence of the change of the production organization and the cost structure on the enterprise cost can be analyzed.

[0077] The production organization is mainly the process path of each production line, and the different process paths have different material yield and hourly capacity, resulting in abnormal cost. The cost composition mainly refers to different cost subjects. The comparison of the actual cost and the standard cost mainly compares the difference between the standard material yield and the actual material yield, the difference between the standard hourly capacity and the actual hourly capacity, and the difference between the standard temperature control and the actual temperature control, etc. Process parameter difference.
