摘要： A piercing mill 10 includes a plurality of inclined rolls 1, a plug 2, a pusher 4, and a guide roll 6. The pusher 4 pushes a round billet 20 from the rear end at least until the round billet 20 advances for a prescribed distance after contacting the inclined rolls 1. The guide roll 6 is provided between the inclined rolls 1 and the pusher 4. The guide roll 6 includes a roll shaft 61 and a roll surface 62. The roll shaft 61 is arranged obliquely with respect to the pass line PL. The sectional shape of the roll surface 62 is a concave arch shape. Furthermore, the guide roll is undriven. The round billet 20 pushed by the pusher 4 is provided with rotation by the guide roll 6. Therefore, the friction force generated when the round billet 20 contacts the inclined rolls 1 is reduced. Consequently, the wear amount of a plurality of inclined rolls can be restrained if the round billet is pierced and rolled while it is pushed in between the inclined rolls using the pusher.

摘要： A process for producing a seamless pipe characterized by including a continuous casting step in which a round billet material having a carbon content of not more than 0.1% by mass and having an outside diameter exceeding 300 mm is cast so that the whole of a central circular region, in terms of cross section, which has a diameter of at least 60 mm may be constituted of an equiaxed crystal structure. Further, in the process for seamless-pipe production, the round billet obtained from the billet material as cast produced in the above continuous casting step may be pierced/rolled with a piercing/rolling machine under conditions in which the ratio of the number of billet rotations to the billet outer diameter draft is set in the suitable range according to the ratio of the gorge portion diameter to the inlet diameter at the inclined rolls, thereby giving a seamless pipe reduced in the incidence of inner surface flaws. Furthermore, as a piercing plug, a suitably configured plug, having a substantially round column-shaped front rolling section with a spherical tip face, may be used, so that Mannesmann fracture and circumferential shear strains are significantly inhibited and no billet onset-engagement failure occurs at all. This process for seamless-pipe production makes it possible to produce a seamless pipe much more improved in inner surface quality with exceedingly high productivity.
