A full-process closed-loop and standardized statistical management method for metallurgical cold rolling waste secondary materials

Abstract

This invention discloses a closed-loop and standardized statistical management method for the entire process of metallurgical cold-rolled waste materials. It achieves full-process control from warehousing to outbound through state-driven mechanisms, standardizes waste material classification through type identification, enables traceability through photographic evidence, and achieves efficient statistics through monthly summaries. This method effectively solves the problems of chaotic ledgers, non-standardized types, and inefficient statistics in traditional waste material management, significantly improving the standardization and traceability of waste material management in cold-rolled production sites. This invention has already been implemented in a factory.

Description

Technical Field

[0001] This invention relates to the field of waste and substandard material management technology in metallurgical cold rolling production sites, specifically to a fully digital closed-loop management method for waste and substandard materials such as plate ends and plate tails, which realizes warehousing registration, outbound control, photo evidence, type standardization, multi-dimensional query and monthly summary. Background Technology

[0002] In the cold rolling production process, the management of scrap materials (plate ends, plate tails, etc.) presents the following challenges: 1. Disorganized ledgers: Traditional paper records or scattered Excel records, with disconnected information on incoming and outgoing goods, resulting in discrepancies between the ledger and the actual inventory; 2. Inconsistent classification: The lack of a unified standard for classifying waste and substandard materials leads to inconsistent statistical methods and data confusion; 3. Difficulty in traceability: Without unified numbering and status management, it is impossible to quickly trace the source and destination of a certain batch of waste materials; 4. Lack of evidence: Without on-site photos, weighing slip photos, or other evidence, weight disputes or management loopholes are likely to occur; 5. Inefficient statistics: Monthly summaries and unit statistics rely on manual calculations, which are inefficient and prone to errors; 6. Unclear permissions: There is no permission control or operation record keeping for inbound and outbound operations, resulting in insufficient data security. Summary of the Invention

[0003] This invention provides a closed-loop and standardized statistical management method for cold-rolled scrap materials. Through state-driven, type-standardized, voucher-based, and multi-dimensional statistics, it enables traceability and reconciliation of the entire lifecycle of scrap materials from warehousing to outbound.

[0004] 3.1 Full-process status control • Inbound operation: Register information such as unit name, pallet type, number, total weight, average weight, inbound date, and inbound person, and mark the status as "not yet outbound"; • Outbound operation: Select the record that has not been shipped, register the license plate number, batch number, outbound date, outbound person and other information, and update the status to "shipped". • Status visualization: Use colors to distinguish between "not yet shipped / shipped", intuitively displaying the inventory status and facilitating quick inventory checks.

[0005] 3.2 Standardized Management of Board Head Types • Supports adding / modifying board header types, setting type identifiers, and standardizing the classification of waste and substandard materials; • The type is automatically linked to the inbound and outbound records to ensure consistent statistical standards and avoid classification confusion; • Type identification can be used to quickly filter and count the amount of waste and defective materials generated and shipped out of different types.

[0006] 3.3 Management of Certificate-Based Photos • Supports uploading two waste discharge photos + a weighbridge photo, which can be linked to the corresponding date and unit; • Photos are linked to inbound / outbound records, serving as evidence for weight confirmation and dispute resolution; • All photo operations are recorded, including the person entering the photo, the address entering the photo, and the time of entry, ensuring auditability.

[0007] 3.4 Multi-dimensional query and statistics • Information Inquiry: Search by combination of unit name, entry date, and exit date to accurately locate records; • Outbound details query: Query outbound records by unit and date for easy reconciliation; • Monthly Summary: Automatically summarizes data by month and unit name, displaying the quantity / total weight of goods received and the quantity / total weight of goods shipped, forming a monthly ledger; • Data Export: Supports one-click export to Excel for cost accounting and audit reporting.

[0008] 3.5 Operation Tracking and Access Control • All inbound, outbound, modification, deletion, and query operations are recorded, including the operator, device address, and operation time. • Provide a record deletion function, which requires precise location by year and month, board type, and number to avoid accidental deletion; • Access control isolation: Only authorized personnel can perform critical operations such as data entry, data exit, and deletion.

[0009] 3.6 End-to-end traceability • Waste and substandard materials are uniquely identified by their serial number and board type, linking all information such as warehousing, outbound, photos, and type. • It can be traced back to: which day, which unit, which batch, who was responsible for the entry / exit of the goods, and the corresponding voucher photos.

Claims

1. A method for managing cold-rolled waste materials, characterized in that, It includes a closed-loop process of inbound registration → status marking → outbound control → voucher retention → statistical summary, and uses color to distinguish the "not yet outbound / already outbound" status.

2. The method according to claim 1, characterized in that, Support standardized management of board head types, and unify the classification standards of waste and substandard materials through board head type + type identifier to ensure consistent statistical standards.

3. The method according to claim 1, characterized in that, It integrates waste discharge photos and weighbridge photos for management, and links them to inbound / outbound records as evidence for quality and weight traceability.

4. The method according to claim 1, characterized in that, It supports multi-dimensional queries by unit name, inbound date, and outbound date, and can automatically summarize the inbound quantity / total weight and outbound quantity / total weight by month.

5. The method according to claim 1, characterized in that, All operations are recorded, including the operator, equipment address, and operation time. Waste and substandard materials are uniquely identified by their serial number and board type to achieve full-chain traceability.
