Cold pilger mill machines perform work on preexisting tubes produced by means of cast, welding or extrusion. Pilgered tube metal alloys include aluminum, copper, gold, silver, stainless steels, titanium, zirconium and a host of many other special materials that are derived from various metal alloys.
Cold pilgering process is a challenging process in terms of modeling since many parameters in the FE model depend on the process conditions, such as heat convection to the lubricant, contact heat transfer coefficient, tool stiffness, etc. Full-scale trials in production were performed to calibrate some of the thermal and mechanical …

1. Introduction. Cold pilgering is a popular cold working process for metallic tubes. Stinnertz (1988) reported that it is widely applied to the manufacture of seamless tubes, including tubes made of steels and copper, titanium, and zirconium alloys. A large cross-sectional reduction of more than 70% is possible in cold pilgering, comparable to …

Pilger rolling or pilger milling is a longitudinal cold-rolling process that reduces the diameter and wall thickness of a metal tube by the synchronized ... We suggest the combination of our 3-step electroplating and subsequent pilger rolling technologies as a promising method to cost-effectively produce composite materials with a large area ...
A numerical model was established to calculate the cycle feed rate through studying the case of a cold pilger mill with the 304 stainless steel pipe. Firstly, the precise constitutive equation of 304 stainless steel was obtained through nonlinearly fitting the true stress–strain data from unidirectional tensile test. Then, the numerical method to …
The paper presents the results of an experiment and numerical simulation in a new pilger tube cold-rolling process, in which the rolling stand is stationary and the rolled tube is placed on a slide and between the rollers. ...

Depending on the material, the cold pilger process achieves cross-sectional reductions of more than 90 percent in a single working cycle. Figure 1 shows the principle of the cold …
Western Energy Material Technologies Co., Ltd. (WEM), based in ShaanXi, China, has placed an order with SMS group for the supply of a cold pilger mill type KPW 25 LC+. With this new cold pilger mill, WEM will be able to satisfy the high demand for cold-pilgered seamless tubes on the Chinese market.
The test machine was a small cold pilger mill with a roll die diameter of 100 mm and a working zone length of 180 mm. The feed rate was 2.5 mm and the turn angle was 75°. The five test pass schedules for the stainless steels and Ti alloy are shown in Table 2, together with the two cold pilgering parameters, i.e., the reduction in area [ Rd ...
Analysis of Mandrel use in Pilger Technology . Apurvkumar Patel . Mechanical Department . GTU . Visnagar (N.G), India . Abstract—Cold pilgering is one type of metal forming process and complex tube making process in which the diameter and thickness of the tube reduces up to 70 percentage. It is
The pilger dies used for this study, as shown in Fig. 1, were fabricated from A2 tool steel with a hardness of between 57 and 59 Rockwell C by double tempering at 510 °C. The chemical composition of A2 tool steel (ASM, 1993) is listed in Table 1.The tapered-groove in the die was ground in a stepwise movement with a circumferential sweeping …
diameter cold pilger defects and improved dimensional control. Metals with certain crystal atomic configurations can have key mechanical properties controlled. The larger reductions can lead to very large extension of the tube hollows which has significant productivity benefits especially where machines do not have automatic continuous loading.
