Abstract
The roll stand of a rolling mill comprises working rollers (3, 4) and idle rollers (6, 7). The longitudinal axes (8) of the working rollers (3, 4) are located in one and the same plane. The longitudinal axis (9) of the upper idle roller (6) is offset in relation to a plane passing through the longitudinal axes (8) of the working rollers (3, 4) by a distance δ1. The longitudinal axis (10) of the lower idle roller (7) is offset in relation to a plane passing through the longitudinal axes (8) of the working rollers (3, 4) by a distance δ2. The offset distances (δ1 and δ2) of the upper and lower roller (6, 7) are inversely proportional to the rigidity of the corresponding section (12 or 13) of the stand in relation to the gap between the upper and lower roller (3, 4).
