    摘要: In a method and a roll stand for diagonal rolling of medium or thin-walled tube ingots, an inner mandrel rod is held at an inlet side and controllably axially displaceably relative to rolls. In order to avoid a funnel-shaped expansion at the tube ingot end, the rolling product during rolling is rolled in a constriction of the mandrel rod and thereby obtains a thickened wall forming a support of the tube ingot wall against the expansion.

    摘要: A multistand rolling mill for stretch reducing tubes is provided in which the first stands of a plurality of successive stands are operated to build up tension and at least one of said stands is provided with means for varying the roll speed to provide a desired speed step in those stands designed to build up tension.

    摘要: A sizing mill is provided for reducing tubes having a number of roll stands arranged one behind the other and in which the sizing pass of at least the first stand is so out of round that the first sizing pass can effect tube reduction over the whole range of external diameters of tubes to be rolled in any given rolling program.
