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 pulse current processing apparatus includes a bidirectional tension and pulse current application apparatus, a real-time thin metal strip shape detection apparatus and a supporting base. In the apparatus, the tension is applied in the rolling direction and the transverse direction to effectively improve the strip shape flaws of the thin metal strip, and realize the rapid straightening of the thin metal strip; at the same time, the stress status of the thin metal strip is changed by applying the pulse current along the rolling direction or the transverse direction or applying different tensions in two directions; secondly, compared with the conventional heat-preservation heating and annealing apparatus, the pulse current can realize high-efficiency control of mechanical properties of the thin metal strip, and rapidly eliminate the internal stress; further, the strip shape is monitored by the laser ranging to ensure the strip shape consistency of the thin metal strip.
