Abstract (en)
[origin: DE4339228C1] The invention relates to a multi-stand rolling train for the longitudinal rolling of seamless steel tubes in a continuous rolling operation over an internal tool using two-roll stands installed offset at 90 DEG to one another and with appropriately calibrated rolls capable of radial adjustment relative to one another. According to the invention, at least the rolls of the last rolling stand (n-1) in the rolling direction are divided in their centre plane, which intersects the roll axis (1) at right angles, and the two halves (2, 3) of the divided roll can be adjusted axially relative to one another. <IMAGE>
