QUALITY INFORMATION MANAGING METHOD FOR STEEL PRODUCT

摘要

PROBLEM TO BE SOLVED: To provide a steel-product quality information managing method for managing quality information occurring in a manufacturing process of steel products, and particularly a steel-product quality information managing method that enables both a manufacturer and each client to own the quality information jointly. SOLUTION: The steel-product quality information managing method includes a step in which a manufacture of steel products is allowed to accumulate quality information generated in a manufacturing process of the steel products into a data base, and a step in which another manufacturer and/or a client who further processes the steel products is allowed to read out on-line the quality information accumulated in the data base.
