Tandem Cold Rolling Mill Factory High Precision Steel Processing Suppliers in China
Our Tandem Cold Rolling Mill is a high-performance industrial solution engineered for precision steel strip processing. By integrating advanced HAGC (Hydraulic Automatic Gauge Control) across five stands, this mill achieves a massive reduction rate in a single rolling process, transforming steel strips from 3mm down to 0.3mm, perfectly meeting the rigorous standards for zinc galvanizing base plates.
Designed for maximum operational efficiency, the system features a fully continuous production flow from the payoff reel to the tension reel. With the integration of automatic welding, high-precision digital DC speed control, and a robust PLC-based automation framework, this mill significantly reduces personnel costs while maximizing yield and gauge precision for demanding metal processing applications.
