Rolling mill and rolling method

A rolling method for the production of a pipe-like work piece, using at least two successive consecutive rolling stages, wherein the two rolling stages perform the rolling with a mandrel rod in the first rolling stage and another mandrel rod in the second rolling stage, the method comprising:

• rolling a work piece in the first rolling stage being a cross-roll piercing method using the mandrel rod of the first rolling stage in order to form the work piece from a block into a hollow block with the mandrel rod of the first stage located in an interior of the work piece;
• bringing the work piece from the mandrel rod of the first rolling stage onto the mandrel rod of the second rolling stage by inserting the mandrel rod of the second rolling stage into the interior of the work piece without entirely removing the mandrel rod of the first rolling stage from the interior of the work piece and without changing a direction of movement of the work piece and without braking the work piece and accelerating the work piece once again,
• wherein the mandrel rod of the second rolling stage moves with the work piece during the second rolling stage, and wherein the second rolling stage is a mandrel rolling method.
