The hollow shell is then elongated in the pilger mill followed by the sizing operation in a sizing mill. Plug rolling process In this mill piercing is done in a cross roll piercing mill to produce a thin wall hollow shell which is elongated to between 3 and times of its original length, corresponding to a deformation level of 65 % to 75 %.

Cold pilgering is a longitudinal coldrolling process that reduces the diameter and wall thickness of metal tube in one process step. Depending on the material, the cold pilger process achieves crosssection reductions of more than 90 percent in a single working cycle. Figure 1. The cold pilgering process relies on four main actions: The tube ...

Among the above processes, the Plug Mill is considered outdated. Push bench is used for commercial tubes and for cold drawing blanks. The Diescher process which had become obsolete has been revived in the recent years as a flexible, low investment process for manufacture of mechanical tubing of smaller dia. The Pilger Mill is suitable to roll ...

Pilger cold rolling is an important technology of rolling metal pipe and it has been widely used in processing titanium, zirconium alloy and other metal pipe manufacturing, whose accumulated deformation section is large [1,2,3,4,5,6].Later, Ukai et al. [] proposed pilger cold rolling technology which can also be used to process lowplasticity metal such as oxide dispersion strengthened metal.

Cold pilgering is a rolling process in which the diameter and wall thickness of metal tubes is reduced. During this process, a large number of forming steps are completed to improve the roundness, stresses, homogeneity, and surface roughness of the tubes. SMS group's cold pilger mills are also suitable for forming difficult materials with a high cross section reduction that are beyond the ...

A new method of evaluating the workability of a tube in cold pilgering has been studied on the basis of material deformability and the effects of process conditions. A circumferential compression test of a tube is confirmed to be an effective evaluation method for deformability. The critical reduction in height upon crack initiation in the compression test is also found to be a good measure of ...
