摘要： 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.

摘要： The present invention relates to a method for producing a coated metal wire for reinforcing an elastomeric material, as well as to such a coated metal wire. Preferably, the wire comprises a metal core (6) and a coating layer made of made of a metal alloy material, such as for example brass. The method of the invention comprises the steps of conveying the metal core along a predetermined path in a substantially continuous manner, the predetermined path being positioned in proximity of at least one cathode (1, 2) made of a metal alloy material having a first composition, and of sputtering the at least one cathode (1, 2) onto the metal core (6) being conveyed along the predetermined path to obtain the coating layer, at least one portion of the predetermined path lying outside of a volume defined by a generatrix substantially perpendicular to a contour line of the at least one cathode (1, 2), so that the coating layer formed when the metal core is conveyed in correspondence of the at least one portion of said predetermined path has a second composition different from the first composition. In this way, the reactivity of the coated wire can be advantageously varied as a function of the reactivity of the wire elastomeric material, so as to allow to produce a metal wire coated with brass (or with another metal alloy) suitable for elastomeric materials having different compositions.
