ABSTRACT:
A multi-stand roll train for longitudinally rolling seamless steel tubes in a continuous rolling process around an internal die using integrated two-high stands staggered by 90.degree. with correspondingly grooved rollers. The rollers are radially adjustable relative to one another, and at least the rollers of the final roll stand in the direction of rolling are divided along a central plane which vertically intersects the axis of the roller to form two halves. The two halves of the divided roller are axially adjustable relative to one another.
