Analysis of tube deformation process in a new pilger cold
Introduction. 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.The system not only enables a 100 % measurement of all produced threads; it also ensures an evaluation and documentation of the measurement data.

Today, it is mainly tubes for the power generation, petrochemical, and construction industries that are produced on hot pilger mills. A key feature of SMS group’s hot pilger mills is the large dimensional range of rollable stock even for high-alloy steel grades.What is claimed is 1. A method of machining grooves in rolls of hot pilger mills wherein a roll contour varies with the rotation of the roll being grooved in a machining zone and has an arc-defined central portion and bevel flanks conjugated by said arc in each radial section, comprising imparting a rotary feed movement to said roll; machining said contour arc METHOD OF MACHINING GROOVES IN ROLLS OF HOT PILGER MILLS

Microstructure Evolution of Cold Pilgering Stainless Steel Tubes
The 347 stainless steel tube cold rolling test was carried out by a LG60 two-roll pilger mill. The microstructure evolution was examined by microscope, SEM, and XRD tests. The finite element software DEFORM-3D has been used to simulate the pilgering process, and the obtained equivalent stress and metal flow were analyzed. The A Pilger mill is a specific type of rolling mill that uses a pair of dies to reduce the diameter and wall thickness of metal tube in a single pass. In this guide, we will cover the basics of pilger mills, including how they work, the different types of pilger mills, the benefits of using a pilger mill, and how to properly care and maintain a pilger mill.Pilger Mill: Guide to FAQs

EDTR Pilgering Certificate
Master the fundamentals of pilger mills! This two-day certificate course for engineers and managers focuses on the basics of pilger mills. Through presentations, case studies, and easy-to-understand exercises, you'll come to understand all aspects of pilger mills. You will learn the history of pilgering, basic components of all pilger millsIn step 1, the housing moves forward. This causes the profiled cams to push the rollers into the tube, compressing it. In step 2, the housing moves back to the start position, with the rollers following the cam until they are once again removed from the tube. In step 3, the tube and mandrel rotate.HPTR’s past, present, and future — Part I The Fabricator
