摘要： The invention relates to a method of rotary piercing in seamless tube manufacturing under a rotary piercing process, such as Mannesmann mandrel mill process. Rotary piercing operation is carried out by employing a rotary piercing mill having a pair of cone-shaped main rolls adapted to cooperate with a plug for rotary piercing and disc rolls disposed in opposed relation between the pair of main rolls and adapted to press hollow shell on the surface thereof. In this method of rotary piercing, the main rolls have feed and cross angles designed to meet certain conditions individually and in combination. The method makes it possible to carry out rotary piercing of less hot workable and/or extremely hard-to-work materials, that is, high-alloy steel billets, without surface torsional deformation and circumferential shear deformation. Thus, it is possible to manufacture high quality tubes of high-alloy steels free from outside seams and inside bore defects.

摘要： A method for manufacturing a seamless pipe, capable of preventing the carburization phenomenon that occurs in a manufacturing process of pipe and simplifying an elongation rolling process, is provided. In this method, after piercing in the piercing rolling process, rolling is performed without using an inside regulating tool in the elongation rolling process, or without performing the elongation rolling followed by reducing rolling in a reducing rolling process, and thickening reducing the wall thickness is then performed by use of a cold mill or cold draw bench in a cold rolling process. According to this method, the trap of graphite fine particles in the inner and outer surfaces of the pipe that took place in the conventional elongation rolling process can be minimized to prevent the carburization of the pipe. The method of the present invention is effective, particularly as a measure for preventing the carburization of an ultra-low carbon stainless steel or high alloy steel.

摘要： An exemplary embodiment of the invention provides a method for producing an ultra thin wall metallic tube by cold working method with significant wall thickness reduction. In a method for producing the metallic tube with a cold pilger mill according to the invention, cold rolling is performed while tube diameters are being expanded using rolls having tapered groove dies whose calibers increase from an engaging entry side toward a finishing exit side. In a method for producing the metallic tube with a drawing machine according to the invention, cold drawing is performed while the tube diameters are being expanded using a solid die whose calibers increase from an engaging entry side toward a finishing exit side and a plug of a tapered mandrel bar whose diameters increase from an entry side of the die toward an exit side. In the metallic tube producing method, a maximum diameter of the plug or tapered mandrel bar may be larger than an outside diameter of the mother tube.
