Cold rolling line
Librastar

Cold rolling line Librastar is the perfect line to produce cold roll steel wire coils, smooth, ribbed or indented, to be used in products as reinforcing welded mesh, stirrups, cages and lattice girders for the civil and industrial construction, foundations and precast industry.

Cold rolling line Librastar combine the cold rolling process of the wire rod with the spooling of the cold rolled reinforced wire to the desired coil weight.

The shape and engineering details of the line allow to produce high-quality cold roll coils with excellent mechanical and geometrical properties of the ribbed profile. The final product can feed any type of welding reinforcing mesh machine or cut and bend equipment.

The Librastar machine is our standard solution for the production of cold roll steel wire coils.

The core of the machine is the Librastar body. Inside there is the bullblock with horizontal axis, equipped with the wire drawing capstans (possibility to install up to 4 capstans) and is able to produce cold roll steel wire coils with a diameter range from Ø4 to Ø20mm and a weight capacity up to 8 tons.

The wire rod, pulled by the high-performances bullblock and driven by the PLC of the last generation, is cold rolled by the rolling cassettes (with the possibility to install up to three rolling cassettes) that reduce the diameter to the desired size improving the mechanical properties and adding the positive ribbing or the negative indentation to the wire.

The machine can be also equipped with stretching panels (at the place of rolling cassettes) to produce stretched wire starting from rebar in coil material.

All the electric, hydraulic and lubrication systems are conveniently arranged inside the machine in order to simplify the maintenance of the line.

At the beginning of the machine a payoff system (with a vertical pay-off tower with two tilting fingers or with an horizontal pay-off beam, according to the wire sizes) is used to feed the machine with the plain wire produced in the hot mill process.

Other devices, like mechanical descaler or wire drawing lubricant machine are included.

At the exit, a wire spooler machine with horizontal or vertical axes realizes the winding of the wire on the spools.

In the highest level of automation of our plants, the above mentioned machine can be equipped with an automatic vertical wire spoolers that make all the operations like insertion of the wire, cutting, change of the spools, samples taking, strapping, labeling and weighing of the coils without any intervention of the operator.

The shape and engineering details of our lines allow to produce high-quality cold roll coils packaged in fixed or take a part spools with adjustable weight up to 8 tons. Normally, the coils produced are used for reinforcing mesh, stirrups, cages and lattice girders for the civil and industrial construction, foundations and precast industry.
