摘要： A manufacturing method of a seamless metal pipe includes: preparing a plurality of mandrel bars in which lengths of work portions which come into contact with a hollow shell during elongating are different from one another; selecting a mandrel bar including a work portion having a length corresponding to the number of stands used in thickness reduction, among the plurality of mandrel bars; inserting the mandrel bar selected in the selecting into the hollow shell; and performing the elongating on the hollow shell into which the mandrel bar is inserted. Moreover, in the elongating, outer diameter reduction is performed by one of a preceding-stage stand group and a succeeding-stage stand group and the thickness reduction is performed by the other of the preceding-stage stand group and the succeeding-stage stand group, or the thickness reduction is performed by both of the preceding-stage stand group and the succeeding-stage stand group.

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： The invention relates to a device for the optimized circulation of mandrels, comprising a presentation and/or cooling table (1) for mandrels, a lubricating station (2) for the mandrels, in some cases an additional drying station for the lubricant applied to the mandrels, and associated roller conveyors (3, 4). A further secondary circulation of rods is arranged upstream of the standard circulation of rods and comprises two redundantly operating transfer tables (11, 12), which are connected to the presentation and/or cooling table by means of a third roller conveyor (2) or the first roller conveyor for the discharge of no longer needed rods from the standard circulation of rods, wherein the third roller conveyor either forms the continuation of the first roller conveyor or is arranged parallel thereto at an offset. Furthermore, a fourth roller conveyor (9) for accommodating mandrels or passing mandrels into the standard circulation of rods by means of an intermediate buffer in an intermittent manner is provided on the opposite side of the transfer tables parallel to the first roller conveyor.

摘要： The invention concerns a method for placing plugs on a plug mill, the method calling for the plug, on completion of the rolling of a tube, to be removed from its position against a rod and to move downward, by virtue of its weight, out of the roller-line, to be return-cooled and then raised back into the vicinity of the roller-line. The invention calls for the plug to move along an elliptical path when being raised and to adopt, before being deposited, a holding position which is at about the same height as, and to one side of, the roller-line. The invention also concerns a device for placing the plugs, the device having a slide, a cooling device and a lifting device with two plug-change arms (1, 2) whose movement is linked by a crank gear (3). The upper arm (1) is connected to the crank gear (3) at two points while the lower arm (2) is connected to the crank gear by a push-pull rod (4) and via cranks (14, 17, 12).

摘要： In a pilgrim-process rolling mill, the mandrel-breaker bush (16) is mounted to the spindle (7) on which it is guided for movement between two stop ledges (19,20) in axial alignment relationship with the mandrel (10) accommodating seat (16). Thus, the rolling mill reliability can be improved and replacement of the bush at each rolling course eliminated.

摘要： An inner surface regulation tool includes a mandrel, a plug which is detachably connected to the mandrel, and a connection member which connects the plug and the mandrel by a magnetic force. One of the plug and the mandrel includes a column-shaped portion which extends in an axial direction of the one, and the other of the plug and the mandrel includes a joining hole which extends in an axial direction of the other and into which the column-shaped portion is inserted. In addition, the connection member is a permanent magnet which is attached to at least one of the column-shaped portion and the joining hole.

摘要： A mandrel holder head with release/fastening device of the mandrel for rolling metallic tubes comprises a mandrel holder (1) which accommodates within an internal seat a half collar (2) of externally cylindrical shape through an opening in the side wall. In the internal seat are accommodated both an end part (52) of the mandrel shank and the half collar (2) through the opening. The half collar has an internal cavity with a second longitudinal side opening which accommodates a second part (51) of the shank of diameter smaller than that of the first part (52). The half collar is divided along an axial direction into two cylindrical parts (21, 22) which have different diameters. The locking member (30, 31) of the half collar (2) holds it in the mandrel holder (1) seat in working conditions, while allowing shank release with an axial movement in locked conditions.
