Description

Technical Field

[0001] The invention belongs to the technical field of industrial automation control, and in particular relates to a scrap steel quality inspection deduction quantity determination system. Background Art

[0002] As an important raw material for steel production, the quality of scrap steel directly affects the quality and performance of steel products. In the process of scrap steel recycling and processing, due to its diverse sources and complex composition, scrap steel is often mixed with various impurities and unqualified products, such as plastics, rubber, and soil. The quality inspection of scrap steel materials is a key link for steel enterprises. It is related to the production quality, cost control and stability of the supply chain of enterprises. However, many steel enterprises do have some problems in the quality inspection of scrap steel materials, especially over-reliance on human eyes and human experience to determine the deduction of scrap steel materials; first of all, this practice is not only inefficient, but also easily affected by the subjective factors of quality inspectors. Different quality inspectors may give different deduction judgments for the same batch of scrap steel materials, resulting in inconsistent and inaccurate quality inspection results. Secondly, there is also the possibility of collusion between quality inspectors and suppliers, which increases the integrity risk of the quality inspection process. Some quality inspectors may be tempted by the interests of suppliers to relax the judgment standards or improve the grade judgment results, resulting in unnecessary expenses for enterprises and even economic losses. This behavior not only damages the interests of steel enterprises, but also may undermine the fairness and stability of the entire supply chain.
