    摘要: The present application relates to a vibration damping system for a rolling mill comprising a rolling cage and a bending adjustment system (3,3′) of the rollers comprising hydraulic actuators acting on the rollers and hydraulic circuits (18, 19) for feeding, and hydraulic damping means (25, 31, 32) of a force connected to the hydraulic circuits (18, 19) for actuating a damping effect by means of the hydraulic actuators. The hydraulic damping means comprises a pair of hydraulic pumps (25B, 25C) or a pair of hydraulic cylinders with a dual chamber, connected in an opposite direction to each other to the hydraulic circuits (18, 19).
