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. Danieli & C Officine Meccaniche SpA – Italy Email: r.villa@danieli.it Website: www.danieli.com
