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.
