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 ...
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.
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,...

The cold pilgering process is suitable for all metals. Typical materials are mild steel, stainless steel, ferritic steel, low-alloy steel, copper and copper alloys, titanium alloys, zirconium alloys, and nickel alloys (see Figure 4). Using cold pilgering to reduce precious metals is conceivable, because practically no material loss occurs.
1. 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 influence of technological factors and constructive parameters of the cold pilger rolling mill to the warm conditions of deformation is observed. The dependences of the heat conditions of...

"The Tunica plant manufactures both hot and cold finished seamless pipes in stainless steel grades, duplex and super duplex grades, nickel alloys, and various titanium grades. The maximum outside diameter produced is 20", while wall thicknesses range from 10S up to XXS in lengths up to 12 meters or even longer if need arises," explains Mr. Zwick...
mechanical FE model of the cold pilgering process is developed. The Johnson-Cook model is used to describe the flow stress accounting for temperature, strain rate and strain path dependency. 2 BACKGROUND The estimation of roll separation force is required for pilger mill design andto determine limits for tube dimensions or process parameters.
Cold pilgering is a cold forming process used to manufacture seamless tubes which for some materials enables area reductions more than 90%. During the process, the tube is compressed between a mandrel on the inside and two rolls on the outside, which are oscillating forward and backward. Before each forward and/or backward stroke, the tube is fe...

Cold pilgering is a longitudinal cold-rolling process that reduces the diameter and wall thickness of metal tube in one process step. Depending on the material, the cold pilger process achieves cross-section reductions of more than 90 percent in a single working cycle. Figure 1
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,, 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 entry plane, the groove cross-section is equal ...
