Verification of Pilger Mill Performance

Sep 24, 2018· The conversion of the rolling mill to a pilger mill consisted of removing the mechanical linkages that connected the gear motors to the roll dies. The pilger mill system was designed to use index-able servo motors that are connected to the large drive rolls directly. This design allows for more flexibility in the degree and speed of die rotation.

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.
