In the modern metal processing industry, the precision and quality of thin steel sheets directly determine the performance and application of downstream products. In sectors such as automotive, home appliances, electronics, and construction, the demand for high-precision cold-rolled sheets continues to grow. The Φ185/Φ560×700 Four-High Two-Stand Tandem Cold Rolling Mill is designed to meet these requirements with outstanding performance.
This mill adopts a two-stand four-high structure, where the combination of work rolls and backup rolls effectively disperses rolling pressure, ensuring uniform strip thickness and excellent surface finish. Compared with single-stand mills, the tandem configuration achieves greater thickness reduction in a single pass, reducing the strip from 3.0 mm to 1.8 mm while avoiding multiple rolling cycles that increase energy consumption and lower efficiency.
Equipped with a hydraulic Automatic Gauge Control (AGC) system, the mill can adjust rolling force and roll gap in real time, keeping thickness deviations to a minimum. Together with Siemens electrical control and a DC motor drive, the mill ensures stable parameters even at high rolling speeds. Additionally, it is capable of processing a wide range of carbon steels such as Q195, Q235, SPCC, and SPCD, offering customers more flexibility.
The process flow includes loading, decoiling, hydraulic shearing, accumulator, two tandem mill stands, recoiling, and unloading, enabling continuous production and consistent product quality. This makes the mill particularly suitable for high-volume, high-precision sheet production, helping enterprises reduce costs while meeting the stringent material requirements of lightweight automotive design and miniaturized electronic components.
For steel processors seeking both capacity and quality, the Φ185/Φ560×700 Four-High Two-Stand Tandem Cold Rolling Mill is more than just equipment—it is a comprehensive, reliable high-precision production solution.
