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： A tapered roll stand for making seamless pipe has a stationary frame formed relative to a workpiece-travel direction with a pair of laterally and horizontally oppositely open windows. Respective cover doors carried on the frame are vertically shiftable between respective closed positions covering the respective windows and open positions offset therefrom and exposing the respective windows. A pair of tapered rolls are each shiftable horizontally through a respective one of the windows into a use position inside the frame, lying to a respective horizontal side of the direction, and rotatable about a respective axis forming an acute angle with the direction. A pair of Diescher disks are vertically engageable with a workpiece extending in the direction between the tapered rolls, and respective roll-positioning actuators carried on the doors are couplable with the tapered rolls in the use position for setting positions of the tapered rolls.
