2025year1moon，The declaration of Daye Special Steel《Application practice of intelligent quality closed-loop control solution for the entire process in special seamless steel pipe factories》Selected by the Ministry of Industry and Information Technology2024Typical Cases of Annual Quality Improvement and Brand Building，Becoming the first intelligent quality control demonstration project in the national seamless steel pipe industry。
This system uses multi-dimensional online detection、Quality Data Collection and Governance、based onPDCAIntelligent control and other technologies，Realize the improvement of yield rate3%、Decrease in product defect rate50%、Improved work efficiency40%，Annual economic benefits reach tens of millions of yuan。
technical pathway：
Intelligent Quality Closed loop Control System of Daye Special Steel，The core lies in“data-driven+intelligent decision-making”。for example，In the hot rolling process，The system obtains real-time pipe size data through laser scanning，combineAIAlgorithm dynamically adjusts rolling parameters，Adjust the wall thickness deviation from±0.2mmCompressed to±0.08mm；In the quality inspection process，Using machine vision technology to detect surface defects in pipes100%Auto Detection，Detection rate reaches100%，The over inspection rate is lower than1.8%。Besides，The system has also been established“blank-heat-rolling-finishing-reservoir area”Full process digital twin model，Realize full coverage of production process visualization and quality traceability。
Industry significance：
Promotion of the system，Marking the transition of the seamless steel pipe industry from“Experience quality inspection”to, toward, at, facing“data quality inspection”transformation。According to statistics from the China Iron and Steel Industry Association，At present, the average quality inspection cost of seamless steel pipe enterprises in China accounts for a certain percentage of the selling price8%，And Daye Special Steel uses an intelligent control system，Compress this cost to3%，At the same time, the quality objection handling cycle will be extended from72Shorten hours to8hour，Significantly improve customer satisfaction。future，with5G+Popularization of industrial Internet technology，Intelligent quality control will become a standard in the industry。
