A Method for the Control and Full-Process Traceability Management of Acceptance Standards for Auxiliary Materials in Metallurgical Cold Rolling Production

Abstract

This invention discloses a closed-loop management method for the entire process of acceptance of auxiliary materials in metallurgical cold rolling production. Through standardized acceptance configuration, dual-dimensional linked testing, unified maintenance of manufacturer information, and full-chain traceability, it solves the problems of chaotic acceptance standards, missing testing, and difficult traceability in traditional auxiliary materials. This significantly improves the standardization and traceability of quality control of auxiliary materials in cold rolling production, ensuring stable quality of finished strip steel. This invention has already been implemented in steel mills.

Description

Technical Field

[0001] This invention relates to the field of quality control technology for auxiliary materials in metallurgical cold rolling production, specifically to a digital acceptance management method for auxiliary materials in cold rolling production (such as acid solutions, passivation solutions, etc.), which realizes warehousing registration, dual-dimensional testing, standard control, manufacturer management, and full-process traceability. Background Technology

[0002] In the cold rolling production process, the quality of auxiliary materials directly affects the performance of the finished strip steel. Traditional auxiliary material acceptance management has the following pain points: 1. Inconsistent testing standards: There is no standardized management of acceptance thresholds for different units and different auxiliary materials, which can easily lead to judgment bias; 2. Missing testing steps: Relying on a single testing method cannot cover the dual verification requirements of on-site sampling and laboratory retesting; 3. Disconnect between warehousing and acceptance: Warehousing information is separated from test results, making it impossible to achieve quality control of "acceptance before warehousing"; 4. Difficulty in traceability: The lack of a complete record of auxiliary materials from manufacturer, warehousing, testing to use makes it difficult to quickly locate the root cause of quality problems; 5. Inefficient statistics: Acceptance results and non-conforming data rely on manual compilation, which is inefficient and prone to errors; 6. Disorganized manufacturer management: Information on auxiliary material manufacturers is not maintained in a unified manner, making it impossible to effectively assess the quality of suppliers. Summary of the Invention

[0003] This invention provides a closed-loop management method for the entire process of cold rolling production auxiliary material acceptance. Through standardization, dual inspection linkage, status control, and full-chain traceability, it achieves standardized and visualized management of auxiliary material quality.

[0004] 3.1 Standardized Management of Acceptance Standards Configure the lower and upper limits of acceptance items by dimension: unit name + unit name + auxiliary material name; Clarify whether on-site sampling or laboratory sampling is required for each project, and form a unified acceptance standard system; Standards and auxiliary materials are automatically linked, and the corresponding threshold is automatically called during incoming inspection to avoid errors from manual judgment.

[0005] 3.2 Information Management of Auxiliary Material Manufacturers Maintain material codes, material descriptions, and manufacturer information for auxiliary materials, and establish a unified supplier file; Supports adding / modifying / deleting manufacturers, and records the operator, operation address and operation time to ensure data auditability; Linking manufacturers with auxiliary materials and acceptance records facilitates subsequent statistical analysis of supplier quality performance.

[0006] 3.3 Warehousing and Dual-Dimensional Detection Closed Loop Warehouse entry registration: Enter basic information such as auxiliary material name, warehouse name, storage location number, entry date, and quantity; Dual-dimensional detection: Simultaneously input on-site sampling results and laboratory sampling results, and automatically determine whether they are qualified by comparing them with preset standards; Results linkage: Test results are linked to warehousing records, and unqualified auxiliary materials are not allowed to enter the production process, realizing "inspection before use".

[0007] 3.4 Multi-dimensional query and statistics Supports multi-dimensional queries by company name, acceptance time, auxiliary material name, project name, whether it is qualified, and warehousing date; It can quickly filter unaccepted / accepted auxiliary materials and intuitively grasp the inventory quality status; It supports data export for use in quality analysis, supplier evaluation, and audit reporting.

[0008] 3.5 End-to-end traceability and operation record keeping Using the material code + sampling batch as a unique identifier, it links manufacturer information, warehousing data, test results and operation records; All add, modify, and query operations are logged, recording the operator, device address, and time to ensure data traceability; When a quality anomaly occurs, it can be traced back to the specific batch, testing process, and responsible personnel.
