Method and device for flexibly rolling a metal strip

摘要

The metal band is rolled between two rollers, with size-variable rolling gap (4) to achieve band sections of smaller or larger thickness. To achieve a band section of smaller thickness, the contact period of each peripheral point of a first working roller (2) with the metal band (1) is shorter than the contact period of each peripheral point of a second working roller (3) with the band. This gives an asymmetrical thickness profile in the band sections with smaller thickness. The first working roller rotates at a higher speed than the second working roller.
