Bühler Würz Kaltwalztechnik
and Maschinenfabrik Niehoff have
presented a production line for
manufacturing PV-Ribbon made of
copper.
Ribbon is rolled by the mill from
round copper wire and is tuned by
in-line process by induction annealer
to the desired mechanical properties.
Dimensions that can be handled are
1 to 7mm width and 0.03 to 0.7mm
thickness.
The yield strength (Rp 0.2) of the final
ribbon is ≤ 80Mpa, and the ultimate
strain is > 25%.
The maximum speed of the
production line is 1,000m/min, and
this applies to the rolling process as
well as to the integrated annealing
process. For example, an output
capacity of 1,500t/pa can be achieved
for a solar strip with the dimensions
5.0 x 0.1mm.
Bühler Würz Kaltwalztechnik is a
manufacturer of cold rolling mills
for steel and non-ferrous alloys with
long-time tradition and extensive
experience in rolling technology for
different applications.
Together with its partners, Niehoff
develops production systems
that address all of the needs and
preferences of wire and cable
manufacturers.
Constant improvements are
incorporated into the production
systems, reflecting the latest
advances in technology.
