The hydraulic system of cold rolling mills is primarily used in cold rolling equipment such as pickling, rolling, annealing, galvanizing, leveling, and recoiling. Professional hydraulic system control technology ensures precise control of the main equipment’s rolling speed, strip shape, strip thickness, and elongation rate.
TECHNICAL FEATURES
Cold-rolling hydraulic screw-down and automatic thickness control employ an electro-hydraulic servo control system, featuring high reliability, precise positioning accuracy, and rapid response.
