Abstract (en)

[origin: DE19816602C1] The invention relates to a roll stand for hot- or cold-rolling rolled strips consisting of different materials, comprising working rolls, support rolls and optionally, intermediate rolls arranged in pairs. The rolls (6) of at least one pair can be axially displaced towards both sides and have a suitable contour for compensating rolling defects. The disadvantages of rolls which are axially displaced by means of displaceable chocks are avoided since each displaceable roll (6) has at least one hydrodynamic oil film bearing (3) into which the hydraulic unit (17) responsible for effecting the axial displacement is integrated.
