ABSTRACT:
The present invention relates to a roll stand for a planetary rolling mill having roll housings, stationary support bodies which are mounted on insert pieces, which have at least one rolling segment inserted therein, with hardened segment inserts, and intermediate and work rolls mounted in cages and rotating around the support bodies. Upon their rotation around the support bodies, these rolls are brought against the intermediate rolls and the latter are brought against the support bodies. The rolling surface of the rolling segments is formed by the segment inserts which have a flattened cross-sectional shape, in the region of the shaping zone, differing from the circular cross sectional shape of the support bodies having a rolling surface which can vary in position with respect to the support body by displacement of the segment inserts, individually or in groups, in a direction perpendicular to the axis of the support body.
