摘要： The invention relates to a method and a rolling mill for producing a seamless steel pipe in a continuous rolling process, where semi-finished material is first formed into a hollow block (8) in a rotary rolling mill, said block then being rolled in a multi-tooled continuous rolling mill (1) over a previously inserted mandrel (10) to form a tube blank (9), wherein the mandrel (10) receiving the hollow block and held by a mandrel holding and transporting device (5) disposed on the entry side is fed into the continuous rolling mill (1) and is transported back to the entry side after the tube blank has been rolled off of the mandrel (10) on an extracting rolling mill (4) connected downstream of the continuous rolling mill. An aim of the invention is to allow high production rates at the same product quality, particularly at a low drop in the temperature of the tube blanks. The aim is achieved in that the mandrel (10) with the tube blank (9) is released by the entry-side mandrel holding and transporting device (5) after exiting the last tool (2.n) of the continuous rolling mill (1) and thus is transferred to an accompanying second mandrel holding and transporting device (6) connected downstream and held by the same until the tube blank (9) is rolled off by means of the extracting rolling mill (4).

摘要： In order to create a rolling mill, in particular a rolling mill having more than one mill stands, comprising at least two rolls which are mounted in a roll bearing in a mill stand to absorb rolling forces, further comprising means for moving at least one roll relative to the mill stand as well as means for determining the roll pass, said determining means having a pass reference and a spatial reference as well as means for measuring the relative position between the pass reference and the spatial reference, the rolling mill providing as accurate information as possible about the roll pass, the pass reference and/or the spatial reference is/are arranged peripherally in relation to the power flow occurring between the roll and the mill stand.
