Abstract: In order to improve the quality of pipe-like work pieces, a rolling mill has at least two successive consecutive rolling stages that have mandrel rods. A threading line for the mandrel rod of the second rolling stage can lie on an extraction line for the mandrel rod of the first rolling stage. The same advantage can be achieved in a rolling method for the production of pipe-like work pieces, comprising at least two successive consecutive rolling stages, wherein the two rolling stages perform the rolling with the use of mandrel rods. The work piece is brought from the mandrel rod of the first rolling stage onto the mandrel rod of the second rolling stage, without entirely emptying an interior of the work piece and/or without changing the direction of movement of the work piece or braking the work piece in the meantime and accelerating it once again.

Abstract: In order to simplify roll adjustment in a roll stand when changing the rolls, a roll stand absorbs rolling forces of at least three rolls mounted on both sides in bearing seats of the roll stand that absorb rolling forces, in each instance. At least the bearing seats of one roll are disposed in a stand body jointly with a bearing seat of another roll, in each instance. One of the stand bodies has fixed bearings of the two related rolls, in each instance, and/or one of the stand bodies has floating bearings of the two related rolls, in each instance.
