Abstract

L’invention concerne un procédé de production d’un fil métallique utilisable pour le renforcement d’articles de caoutchouc comprenant au moins une étape d’électro-polissage d’un fil métallique de diamètre d1 par passage en continu dans un bain de solvant eutectique profond, en présence d’une densité de courant comprise entre 10 et 50 A/dm², le temps de séjour du fil dans le bain de solvant eutectique profond étant compris entre 10 s et 3 min.The invention relates to a process for producing a metal wire usable for reinforcing rubber articles comprising at least one step of electro-polishing a metal wire of diameter d1 by continuous passage through a bath of eutectic solvent deep, in the presence of a current density of between 10 and 50 A/dm², the residence time of the wire in the deep eutectic solvent bath being between 10 s and 3 min.
