The line for the production of smooth and/or ribbed wires for construction. The line is extremely compact, versatile and equipped with protections to safeguard the operator even in standard version.
The two solutions consider the use of either a vertical axis bull-block or alternatively with a horizontal axis. In both cases, the use of hydraulics has been completely eliminated, as we have chosen the solution with electrical command technology. This choice has allowed Eurolls to simplify the installation and to guarantee a better cleanliness of the line over time.
At the entry of the line, where the descaling panel is located, there is a pinch roll to help during the feed-in operation. Included in the main frame is the rod lubricating unit, and the stands for the Eurolls Cold Rolling Cassettes.
In both proposed solutions, it is foreseen that it would be possible to work in-line with reductions up to 36% and in-loop, for higher reductions.
Using an unprecedented constructive solution, that optimizes the lines ergonomics, space occupied sidewise has been reduced to the minimum, even in cases where the final reductions are greater than 36%.
After the bull-block, (which as an option can be composed of a single, double or even a triple capstan) there is the possibility to install a stress relieving device to improve internal fiber arrangement after the production of cold rolling deformations.
Further options for these type of lines are the addition of another integrated bull-block, to produce a third reduction on the material being processed. This is especially helpful for those customers who are interested in the production of very small diameters (i.e. 3,40 mm).
The line can also be equipped with a spooler with a horizontal or vertical axis, and can be fully automated depending to the specific requirements of the client, (with additional options for customer’s interested in the production of strapped material, or weighed and labeled coils) all without the need of operator intervention. As an alternative, the lines can be paired with Eurolls’s straightening and cutting units for the bars production or even with mesh lines for the in-line supply of cross and line wires.
