Eurolls quick rolling concept QRC

This innovative product has been developed by Eurolls to perform multiple tasks. Its function is to produce wire and thanks to its sleek compact design/dimensions it 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 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 also in the case of the single in-line solution that combined both a QRC unit and a straightening & 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. To perform these drafts can be used 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, one can change the components present in order to produce different final wire products to satisfy the different requirements of the wire sector e.g. traditional reinforcement bars, electrowelded mesh panels etc.

The above just to confirm that Eurolls continues its philosophy of developing leading edge solutions that are applicable directly to different areas of the wire sector.
