Cold rolling
pilger mills
from Italy
TOP quality seamless tubes and pipes
made from sophisticated materials such as
zirconium, Ni-alloy, titanium and stainless
steel are in high demand for many
applications, especially those concerning
nuclear, aerospace, automotive, energy
and power generation industries.
With customers also pressing for
highly qualified cold pilger mill suppliers,
the opportunity arose for Danieli to
develop a wide range of innovative mill
configurations specifically designed for
customers’ ‘critical spots’, both for new
mills and for revamping existing plants.
By adopting a tailored approach Danieli
aims to target customers’ preferences and
priorities right from the very start of the
project. For materials such as stainless
steel, which are difficult to deform, a two
roll quarto design with an extremely rigid
fixed mill stand complete with load cells
to measure separating force is the optimal
solution.
A two roll movable cassette design
is available for ductile materials. Cutting
edge technology for zirconium tubes is a
compact three-roll design with a movable
stand and movable roll cassette.
Danieli’s continuous and discontinuous
cold pilger mills are available in many
different sizes, with ODs ranging from 4
to 250mm and WTs from 0.2 to 20mm.
