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 cold rolling is an important technology of rolling metal pipe and it has been widely used in processing tita-nium, zirconium alloy and other metal pipe manufacturing, whose accumulated deformation section is large [1–6].

For new fast-neutron sodium-cooled Generation IV nuclear reactors, the candidate cladding materials for the very strong burn-up are ferritic and martensitic oxide dispersion strengthened grades. Classically, the cladding tube is cold formed by a sequence of cold pilger milling passes with intermediate heat treatments. This process …
To overcome the above problem, the development of a pilgering die groove shape design method, which is the core design technology of the cold pilger rolling process, is required. In addition, a Q factor evaluation method for the final product, as well as a rolling force prediction method according to the die shape, are needed [3,4,5]. The …
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 …
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 …

COLD-ROLLING MILLS Complete solutions and support packages for cold-rolling mills. A state-of-the-art cold-rolling mill is essential to the production of steel strip that satisfies the tightest tolerance demands at high productivity levels – for carbon, stainless, and special steel grades such as AHSS (advanced high-strength steel).
From on-site inspection to service report and revamp during regular shutdown SMS group Technical Service has now realized a major modernization project with a China-based operator of a cold pilger mill – the KPW 25 VMR. The machine was upgraded to an "as new" condition within a very short period of time and has now an […]
Cold rolling of tubes in pilger mills is a cyclical process that is commonly used in manufacturing of tubes made of hardly deformable alloys. In the classic solution [1], [2], the rolling stand is mobile and moves to-and-fro, and the rollers move with the stand, while turning in opposite directions.A circular groove is cut in the roller, so that in the …
