Verification of Pilger Mill Performance

Sep 24, 2018 · Figure 2.1. Commercial Scale Pilgering. Pilgering has many advantages compared to the drawing process. Pilgering can produce high levels of cold deformation in hard-to-process ODS, as well as produce advantageous textures in the material. The pilgering process allows for higher reductions of area (ROA) in a single pass than the cold draw process.

Introducing cold pilger mill technology

The cold mill pilgering process uses ring dies and a tapered mandrel to reduce tube cross sections by up to 90 percent. Because the process relies on large number of small forming steps, the result is tube or pipe that has nearly homogenous material characteristics. It is suitable for every metal.

TRIBOLOGICAL PERFORMANCE EVALUATION OF COLD

Cold pilgering provides benefits such as close tolerances of inner and outer diameter, good surface finish and very good mechanical properties. Since the normal area reduction of the tube lies between 60 – 85% it is evident that there is severe plastic deformation which generates a lot of heat.

Cold pilger mills | SMS group

Cold pilgering is a rolling process for metal tubes that reduces diameters and wall thicknesses. The Process. Located inside the tube is a stationary mandrel (1) which tapers in the rolling direction. This is attached to a long mandrel bar (2) which is secured in, and rotated by, a thrust block. Two dies (3) "form" the tubular stock in the same way that a rolling pin rolls out pastry.
