    摘要: A manufacturing method of a seamless metal pipe includes determining whether a preceding-stage stand group is used in outer diameter reduction or in thickness reduction of a hollow shell; and performing elongating on the hollow shell, into which a mandrel bar is inserted, based on the determination. In addition, in the elongating, when the preceding-stage stand group is used in the outer diameter reduction, the hollow shell is rolled in a state where an inner surface of the hollow shell does not come into contact with the mandrel bar in the preceding-stage stand group, and the hollow shell is rolled in a state where the inner surface of the hollow shell comes into contact with the mandrel bar in the succeeding-stage stand group.

    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.

    摘要: The apparatus for changing the rolls (6) of a skew rolling mill comprises a roll-change carriage (14) movable along the direction of feed of material (10) being rolled. A carrier (11) is mounted on the carriage (14) and carries a plurality of roll-clamping devices (12). Locking means (19, 20) are provided for interlocking the rotor (2) carrying a plurality of roll heads (5) skew mounted thereon and the carrier (11) in a predetermined axially-aligned, spaced position for removing or replacing rolls by means of the clamping devices. In a preferred embodiment there are two carriers movable in alternate alignment with the rotor (2).
