摘要: 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 δ 1 . The longitudinal axis (10) of the lower idle roller (7) is offset in relation to a plane passing through the longitudinal axis (8) of the working rollers (3, 4) by a distance δ 2 . The offset distances (δ 1 and 0 2 ) 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).

摘要: AA roll comprises an axle (1) with a driven and an idle neck (2, 3) and a shell (4) rigidly secured on the shaft (1). The shaft (1) is provided with trapezoidal protrusions (6) evenly spaced along its circumference with their height regularly decreasing in the direction from the driven neck (2) to the idle one (3).
