The 347 stainless steel tube cold rolling test was carried out by a LG60 tworoll pilger mill. The microstructure evolution was examined by microscope, SEM, and XRD tests. The finite element software DEFORM3D has been used to simulate the pilgering process, and the obtained equivalent stress and metal flow were analyzed. The experimental results showed that the internal slip line was randomly ...

The objective of this study was to design the die groove profile and predict the rolling force produced when employing the variable curvature rolls and mandrel for manufacturing seamless pipes using the cold pilger rolling process. The parameters of the key process design were the diameter of the initial tube and final product, as well as the feed amount, reduction area, principal deformation ...

Depending on the material, the cold pilger process achieves crosssectional reductions of more than 90 percent in a single working cycle. Figure 1 shows the principle of the cold pilger process. As mentioned above, the part of billet (hot, cold rolled or extruded etc. tube) 1 that equals to feeding volume, gets into moving zone of working cage ...

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 ...

The cold mill pilgering process uses ring dies and a tapered mandrel to reduce tube cross sections by up to 80 percent. It is suitable for every metal (Generally employed for 8 mm to 230 mm OD and to 25 mm wall thickness). Figure shows the theory of cold roll mill working process. The pass (section) gradually reduced when roller move ...

losses. These fullscale tests can also cause damage to the expensive cold pilger mill systems. The published literature pertaining to tribology in cold pilgering is very scarce. Baensch [1] and Stapleton [2] have described the cold pilgering process in great details but have touched upon the lubrication aspect very briefly despite its enormous

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 %.
