Abstract: An asynchronous rolling mill with a super large diameter ratio comprises a rolling mill stand, a press-down device, a balancing device, an upper roll system, and an arc-shaped plate device. The arc-shaped plate device comprises an arc-shaped plate, the arc-shaped plate is arranged opposite to the upper roll, and the arc-shaped plate and the upper roll are cooperated to roll strips. The present disclosure also provides a method for rolling a strip using an asynchronous rolling mill with a super large diameter ratio. The asynchronous rolling mill can roll with super large diameter ratio and different speeds, and has a large angle to engage, thereby reducing the external friction force of a workpiece and improving strip forming quality.

Abstract: A vibration suppression method and system of a rolling mill roller assembly based on a vibration damping device are provided. The vibration suppression method includes: obtaining a first amplitude-frequency relationship during a vibration process of a rolling mill roller assembly vibration suppression system; based on the first amplitude-frequency relationship, determining two time domain relationships and two second amplitude-frequency relationships by a simulation analysis; based on the two time domain and relationships two second amplitude-frequency relationships, adjusting parameters of the vibration damping device until a vibration displacement of the rolling mill roller assembly vibration suppression system is less than or equal to a vibration displacement threshold. And provides a new solution for the stability control of the rolling mill, and ensures the reliability and stability of the vibration suppression of the rolling mill.
