NFC orders second cold pilger mill

The Indian nuclear-power equipment developer Nuclear Fuel Complex (NFC), a leading producer in India of niche tubes for nuclear applications, has ordered a second 50-Q-C type Cold Pilger Mill (Quarto design, Continuous feeding) from Danieli W+K.

The mill is designed to produce high-strength, high-temperature, high corrosion-resistant stainless steel grade tubes, with outer diameters ranging from 10 to 35 mm and wall thicknesses from 0.4 to 5 mm.

An exceptionally rigid mill stand configuration capable of resisting extremely high separating forces allows the Quarto to offer the most favourable solution and achieve the very tight geometrical tolerances requested (±0.2 % on outer diameterss and ±3 % on wall thicknesses). Also incorporated into the installation is a continuous and precise shell feeding section, which adopts CNC machine technology and a vibration-free mass balancing system, optimized to reduce CapEx with minimal requirements in terms of foundation works.

NFC is operating a 32-Q-C cold pilger mill for Zircaloy tubes and bars supplied and installed by Danieli in Hyderabad plant during 2016.

Simplified, cost-effective configurations are also available for commodity tube producers.
