roll grinding machine for cold pilger mill diameter

SMS group GmbH: Cold pilger mills

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.

Rolls for cold pilger mills-JIANGSU HERO WAY ROLLING

2020-8-3  In the cold pilger process, thick walled seamless tubes (hollow blooms) are finished to the required final size. The roll stand consists of two rolls that turn in reverse to the rolling direction. The roll profi le steadily reduces, in a taper, to the finished tube diameter. The tube is rolled over an internally located conical mandrel.

Verification of Pilger Mill Performance

2018-9-24  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.
