Disclosed is a method for patenting at least one steel wire, according to which the temperature is increased at least to a level at which the steel (25) austenitizes, followed by quenching in a liquid medium (30) by directing said wire through at least one curtain of cooling liquid so as to obtain a cooling temperature that lies below the austenitizing temperature, said liquid flowing in a turbulent manner substantially perpendicular to the wire, followed by an isothermal stage (31) during which the wire is maintained at a constant temperature allowing pearlitic transformation. The inventive method is characterized by the fact that additionally, a number of successive curtains can be specifically adjusted so as to obtain the temperature which allows pearlitic transformation and is to be kept constant during the isothermal stage as said cooling temperature through the cooling process in a liquid medium, and the isothermal stage immediately follows the cooling process in a liquid medium.
Procédé de patentage d'au moins un fil d'acier, comprenant une montée en température jusqu'à une température d'austénitisation de l'acier (25), un refroidissement brusque, en milieu liquide (30), par défilement dudit fil au travers d'au moins un rideau de liquide de refroidissement dans lequel celui- ci présente un écoulement turbulent orienté sensiblement transversalement audit fil, avec obtention d'une température de refroidissement située en dessous de la température d'austénitisation, et un maintien isotherme (31) dudit fil à une température de transformation perlitique caractérisé en ce qu'il comprend en outre un ajustement d'un nombre de rideaux successifs qui est déterminé pour obtenir, par ledit refroidissement en milieu liquide, ladite température de transformation perlitique à maintenir pendant l'étape de maintien isotherme, à titre de température de refroidissement susdite, et le maintien isotherme susdit directement à la suite du refroidissement en milieu liquide.
