The system's advanced continuous annealing technology maintains exact temperature profiles within a protective atmosphere environment, ensuring oxidation-free processing. After precise heating and soaking cycles, our proprietary cooling and overaging treatments produce consistently optimal material characteristics. The integrated online leveling system further enhances product quality by delivering exceptional strip flatness and surface finish directly in the Continuous Annealing Line.
Based on PLC+ industrial PC architecture, it integrates 200+ monitoring points such as temperature, tension, and speed. It uses an adaptive PID algorithm to adjust 18 core parameters such as furnace temperature and belt speed in real time. It is equipped with an MES interface, fully records process curves and quality data, and supports QR code traceability. Abnormal situations automatically trigger a three-level alarm mechanism with a response time of <50ms.
Adopts a multi-stage countercurrent pickling design, including pre-cleaning, pickling, rinsing, and drying processes. Equipped with an online concentration detector to monitor the concentration of HCl or H₂SO₄ in real time (control accuracy ±2%). The recovery rate of the waste acid regeneration system is ≥95%, and the residual iron content on the strip surface is controlled at <10mg/m². Equipped with a graphite heater, the acid temperature stability reaches ±1.5℃.
