Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of industrial automation control, and particularly relates to a scrap steel quality inspection deduction quantity determination system. BACKGROUND

[0002] As an important raw material for steel production, the quality of scrap steel directly affects the quality and performance of steel products. During the recycling and processing of scrap steel, due to the diversity of sources and the complexity of components, various impurities and unqualified products such as plastics, rubber, and soil are often mixed in the scrap steel. The quality inspection of scrap steel materials is a key link for steel enterprises, which is related to the production quality, cost control, and stability of the supply chain. However, many steel enterprises currently have some problems in the quality inspection of scrap steel materials, especially the excessive reliance on manual visual inspection and human experience to determine the deduction quantity of scrap steel materials. First of all, this approach is not only inefficient, but also easily affected by the subjective factors of the quality inspector, and different quality inspectors may give different deduction quantities for the same batch of scrap steel materials, leading to inconsistency and inaccuracy of the quality inspection results. Secondly, there is a possibility of collusion between the quality inspector and the supplier, increasing the risk of integrity in the quality inspection process. Some quality inspectors may be tempted by the interests of the supplier to relax the judgment standard or improve the grade determination result, resulting in unnecessary costs for the enterprise and even economic losses. This behavior not only damages the interests of the steel enterprise, but also may undermine the fairness and stability of the entire supply chain.

[0003] Therefore, how to overcome the shortcomings of the prior art is a problem that needs to be solved in the current industrial automation control technology field. SUMMARY

[0004] The purpose of the present application is to overcome the shortcomings of the prior art and provide a scrap steel quality inspection deduction quantity determination system to improve the accuracy and fairness of the quality inspection deduction quantity, reduce human intervention, and reduce the influence of subjective factors on the quality inspection deduction quantity determination result, ultimately improving the efficiency and precision of scrap steel quality inspection.

[0082] Stack specific gravity deduction = (weighed weight M2 - container weight M1) ÷ container volume V;

[0083] Impurity amount inspection actual weight = impurity amount inspection total weight - barrel weight;

[0084] Screen under actual weight = (screen under weight - barrel weight);

[0085] Impurity rate = round ((screen under actual weight + non-metallic impurities mass) ÷ impurity amount inspection actual weight × 100, 2);

[0086] Impurity deduction = load × 6% + load × (impurity rate - 3%) × 5

[0087] Rust deduction = net weight 3 ‰ deduction;

[0088] Deduction of exfoliation = exfoliation proportion × 1%;

[0089] Final deduction = the sum of all deductions for this scrap steel type. For example: assuming the scrap steel type is broken small material, the final deduction = impurity deduction + size unqualified deduction + single weight unqualified material deduction + moisture deduction + other deductions.

[0090] 4. The deduction calculation model is released: after the configuration of the deduction judgment and the deduction result calculation formula, the scrap steel deduction calculation model is generated, and the model is released through the data interface.

Deduction result analysis feedback: the scrap steel quality inspection deduction result analysis equipment is built-in Flink stream processing framework running engine, which starts the running of the scrap steel quality inspection deduction model with data through the running engine, and realizes the analysis and real-time calculation of the model based on the combination of Spark big data real-time calculation and batch calculation, and continuously optimizes the model by using deep learning algorithm. At the same time, the judgment result is displayed to the user in a visual form, including the deduction type and the deduction result, the quantity information. In addition, the judgment result is fed back to the scrap steel rating system to guide the subsequent processing process.
