FIELD: machine building.
SUBSTANCE: invention relates to a rolling mill for rolling of hollow parts. Mill comprises section of rolling mill with stands and/or rolling plates arranged in series and forming axis of rolling Y, means of moving mandrel (20) and hollow billet fixed on end part of said mandrel, successively along rolling axis Y and through said stands or rolling dies. Displacement means are configured to move the mandrel and the workpiece along the rolling direction parallel to the rolling axis Y, and through the stands or rolls successively by applying a traction force to the mandrel.
EFFECT: as a result, it is possible to process hollow parts of different diameters.
