ASYNCHRONOUS ROLLING MILL HAVING A SUPER LARGE DIAMETER RATIO AND PLATE ROLLING METHOD

Title:

ASYNCHRONOUS ROLLING MILL HAVING A SUPER LARGE DIAMETER RATIO AND PLATE ROLLING METHOD

Document Type and Number:

WIPO Patent Application WO/2022/166654

Kind Code:

A1

Abstract:

An asynchronous rolling mill having a super large diameter ratio, comprising a rolling mill stand (1), a pressing device (20), a balancing device (21), an upper roll system, and an arc-shaped plate device. The arc-shaped plate device comprises an arc-shaped plate (4), the arc-shaped plate and an upper roller (2) are arranged opposite to each other, and the arc-shaped plate and the upper roller work in conjunction with each other to complete the rolling of a strip. The present invention also provides a plate rolling method using the asynchronous rolling mill having a super large diameter ratio. The apparatus can achieve a super large diameter ratio and rolling at different speeds, has a large nip angle, which is conducive to nipping, thereby reducing the external friction force of a rolled piece and improving strip forming quality. The diameter ratio and speed ratio can be adjusted in a wide range, such that according to process conditions, the metal shear stress is increased, the rolling area is expanded, the metal deformation is promoted, the rolling force is reduced, and energy consumption is reduced.
