    摘要： A pilger die assembly in which the die has an annular body with an opening extending from a central, through bore to the peripheral surface. The opening subtends a circumferential angle at the through bore of less than 180.degree.. The cylindrical arbor has a section of reduced cross-sectional dimension, preferably formed by a flat. The die is positioned with the opening aligned with the flat, slid into coaxial registration with the arbor, rotated to a captured position in which the opening is no longer aligned with flat on the arbor and then pushed axially to engage a key on the arbor in a keyway extending axially from one side face of the die. A stop screw threaded into the arbor adjacent the other side face of the die locks it in place.

    摘要： A caliber roll for rolling consisting of a roll main body having a caliber on the outer circumference and provided with a shaft hole penetrating in the shaft central direction, and a roll shaft inserted into the shaft hole of the roll main body, in which a compressive stress in the widthwise direction of the roll main body is applied to the bottom of the caliber. This compressive stress is applied by forming either the inner circumference of the roll main body or the circumference of the roll shaft in a taper, and shrinkage-fitting or cold-fitting the roll main body and the roll shaft, or by pressing the both end faces in the widthwise direction of the roll main body by means of pressing jig fixed to the roll shaft. Besides, a recess gap is provided in either one or both of the inner circumference in the middle of th widthwise direction of the roll main body and the corresponding circumference of the roll shaft. The roll main body is composed of an iron-based alloy including, by weight, C: 0.75 to 1.75%, Si: 3.0% or less Mn: 2.0% or less, P: 0.030% or less, S: 0.030% or less, Cr: 5.0 to 13.00%, Mo: 0.80 to 5.0%, and V: 0.1 to 0.5%, in which the entire hardness is adjusted to H.sub.R C 52 to 56, and the metal flow is in the shaft central direction.

    摘要： Pilgering apparatus for reducing a tube particularly of zirconium alloy. The reduction is effected by grooved annular dies. Each die has a recess in its bore extending between the surfaces on which the die is mounted on the shaft on which it is rotated. Under the pressure applied to reduce the tube, the die is flexed. As a result of the flexing tension exists in the die in the volume near the recess and pressure is developed in the volume near the groove in which the tube is engaged. The pressure counteracts the tension resulting from the tube-reducing pressure. Each die is case hardened in the region of its grooves but not in the region of the recess.

    摘要： A method of making a seamless, tubular article comprises subjecting a cast tubular workpiece of a corrosion resistant alloy to at least about a 25% wall reduction at a temperature below a recrystallization temperature of the workpiece using a metal forming process comprising at least one of radial forging, rolling, pilgering, and flowforming. The cast tubular workpiece is a centrifugally cast tubular workpiece comprising an inner diameter and an outer diameter.

    摘要： By using a piercing mill that includes a pusher on the entrance side, a plug on the exit side along a pass line, and a plurality of angled rolls as being provided around the plug so as face to each other, in the case where the maximum diameter of an unsound region consisting of center segregation and porosity in a cross section of a billet is d [mm], piercing-rolling is performed under the condition that the plug nose rolling reduction ratio (TDF) expressed by Formula (1) satisfies Formula (2). TDF=(Bd−D1)/Bd  (1) TDF≦−0.50×(d/Bd)+0.06  (6) In Formulae (1) and (2), Bd is the billet diameter [mm], and D1 is the opening [mm] between the angled rolls at the plug nose position. Thereby, when piercing-rolling is performed, the occurrence of an inner surface flaw attributable to the center segregation and porosity in the billet can be prevented reliably.

    摘要： The utilization of smaller dies than those originally intended for a given size pilger mill is made possible for the first time by a new means of strengthening the necessarily small diameter shaft and by novel bearing blocks wherein smaller bearings are mounted off center. The smaller die assembly constructed according to this invention is completely and simply interchangeable with the original die sets and can be inserted in the pilger mill as a matter of course without modifications or adjustments to the machine proper.
