Abstract: The process for manufacturing a steel wire comprises: providing a steel wire; austenitizing said steel wire; patenting said steel wire; drawing said steel wire. The patenting of said steel wire comprises: slow cooling said steel wire to a first predetermined temperature; quick cooling the steel wire to a second predetermined temperature; keeping said steel wire at said second predetermined temperature. During the slow cooling, the steel wire substantially keeps its austenite structure unaltered; with the subsequent quick cooling, the steel wire is taken to the best conditions in order to start the phase change in which the austenite structure is transformed into a pearlite structure.

Abstract: A method for producing a metal wire for reinforcing an elastomeric material as well as a metal wire and a metal cord for reinforcing such an elastomeric material are described. The metal wire comprises a metal core having a predetermined initial diameter and a metal coating layer. The method comprises the steps of: a) submitting the core to at least one surface treatment for predisposing the surface of the core to being coated with the coating layer; b) thermally treating the core; c) depositing the metal coating layer to a predetermined initial thickness on the core by means of a plasma deposition technique; and d) drawing the coated core until the core has a final diameter smaller than said predetermined initial diameter and the metal coating layer has a final thickness smaller than said predetermined initial thickness. Advantageously, it is possible to obtain a wire coated in a uniform and homogeneous manner, including a core having a smooth surface suitable for the deposition of the coating layer and a structure suitable for the cold deformation involved in the drawing step.

Abstract: A reinforcement cord (10), configured to be used for example in a tyre (100) for vehicle wheels, comprises at least two steel wires (1) having a carbon content lower than or equal to about 0.40 % and chrome content lower than or equal to about 2% by weight. Such steel wires (1) are twisted together with a winding pitch (P) greater than or equal to about 14 mm. The use of steel having low carbon content allows the costs to be advantageously kept down without negatively impacting on the rigidity of the reinforcement cord. The possibility of using winding pitches of at least about 14 mm makes it possible to increase both the rigidity of the reinforcement cord and the productivity in the winding step, with consequent further reduction of the production costs, and without there being problems of fraying.
