▲ ▲ The Quick Rolling Concept from Eurolls
The Quick Rolling Concept has been
developed by Eurolls to perform multiple
tasks. Its function is to produce wire
and thanks to its sleek compact design/
dimensions allows the perfect union
between different wire processing
sequences.
Eurolls has supplied this QRC concept
in both multiple and single in-line wire
rolling configurations. In both cases,
the presence of the QRC unit permits
the combination of different/distinct
processes but always with the same goal:
improved production efficiency by having
in a single line for the complete process
from entry material to final product.
An example of the multiple in-line wire
rolling solution was its insertion in a
lattice girder manufacturing system with
five individual QRC units, three for the
longitudinal wires and two for the stirrups
wire.
The same philosophy is present in
the case of the single in-line solution
that combined both a QRC unit and a
straightening and cutting line to produce
the finished twisted square wire in
straight lengths.
In both solutions, the first section is
always the QRC unit whose function
is to pull the entry material from the
pay-off area through both mechanical
descaler and cold rolling cassettes,
by means of dual V grooved pulling
rings which guarantee the traction
required to perform the single or
double wire draft. These drafts can be
performed by using either traditional
cold rolling cassettes or a combination
of traditional/special cassettes in
accordance to the profile required for
the finished product.
In the particular case of twisted square
wire production, the first cassette
performs the standard rolling process
to form the correct intermediate wire
dimension suitable for the second draft
that uses a rotating cassette to produce
the final twisted square profile.
From the QRC unit, the produced
twisted square wire moves directly into a
modified Vitari NR300 straightening and
cutting unit that uses two straightening
roll panels, instead of the traditional
rotating spinner. The final twisted square
bar is then used for the production of
antiskid grating panels.
With the same simplicity and efficiency,
the components can be changed in order
to produce different final wire products to
satisfy the different requirements of the
wire sector, eg traditional reinforcement
bars, electro-welded mesh panels, etc.
