摘要： The present invention provides a seamless tube piercing/rolling plug and a seamless tube producing method in which piercing/rolling is performed with an inclined rotary piercing mill while the seamless tube piercing/rolling plug is used as a piercing tool. The seamless tube piercing/rolling plug is used while a front part and a rear part of the split plug are held as an integral plug, at least the front part is made of low alloy steel, and oxide films are formed on surfaces of the front part and rear part. The present invention also provides a seamless tube piercing/rolling apparatus and a seamless tube producing method in which the front part and/or rear part is replaceable in a tube making process line using the seamless tube piercing/rolling apparatus. In the seamless tube piercing/rolling apparatus, the front part and rear part are held as the integral plug, the front part and/or rear part is removably mounted, a mandrel bar holding the plug goes through the rear part, and the mandrel bar is coupled with the front part. It is preferable that a thickness of the oxide film formed in the front part be set to 200 μm or more while the oxide film formed in the front part is thicker than the oxide film formed in the rear part. Even if a hard working material is pierced/rolled, a seam defect and inside surface defects are eliminated, and excellent life-time of plug and excellent plug cost per production quantity can be achieved.

摘要： A high quality hollow shell in which the occurrence of internal surface flaws caused by the rotary forging effect and/or shear deformation is prevented by suppressing the rotary forging frequency and shear deformation in a transient region at the stage of billet gripping and a worsening of thickness deviations in the top portion of the hollow shell is also prevented is reliably produced with preventing miss-rolling such as incomplete billet gripping and troubles in bottom withdrawal and an increase in the outer diameter of the hollow shell in the bottom portion. A billet is pierced while being rotated and advanced to produce a hollow shell, from which a seamless tube is finally manufactured, using a pair of skew rolls, a pair of disk rolls, and a plug under such conditions that each of the ratio (Dg/d) of the diameter Dg of the gorge portion of the skew rolls and the outer diameter d of the billet, the ratio (Dd/d) of the diameter Dd of the groove bottom of the disk rolls and the outer diameter d of the billet, the ratio (Dd/Dg) of the diameter Dg and the diameter Dd, the inlet face angle θ1 of the skew rolls, and the square root of the product (Ns×Df)0.5 of the rotational frequency Ns of the billet in a transient (non-steady state) region when billet gripping and the reduction ratio Df of the outer diameter of the billet satisfies a prescribed equation.

摘要： A billet is provided on a pass line between a pusher and a plug, and the billet is advanced and caught between a plurality of inclined rolls. At least between when said caught billet contacts said plug and when the piercing and rolling reaches a steady state, the advancing speed of the billet is not less than the advancing speed of the billet when the piercing and rolling is carried out without pushing the billet forward by the pusher in the steady state. By this manufacturing method, inner surface defects at a tip end of a hollow shell can be restrained.

摘要： The present invention relates to a making method for a seamless metallic tube with a tilting roll type piercing rolling mill (piercer). According to the making method for a seamless metallic tube of the present invention, the rotary forging effect and the circumferential shearing strain can be significantly suppressed without generating uncompleted engagement of a billet. Accordingly, a product having reduced inside defects and excellent inside quality can be produced in high productivity. Further, by strengthening a plug nose rolling portion, a sharpened plug nose is obtained and an engagement limit can be increased. Additionally, a product further excellent in the inside quality can be efficiently produced. Accordingly, the present invention can be applied to wide fields of the piercing rolling of the seamless metallic tube.
