Abstract[English]
A method and an equipment for isothermal patenting steel wire without lead or molten metal, comprises controlled cooling of steel wires to a predetermined temperature range, and controlled heat removal during the transformation from austenite to pearlite. A steel wire with excellent strain hardening is obtained.[French]
Un procédé et un équipement de patentage isotherme de fil d'acier sans plomb ou métal fondu, font appel au refroidissement contrôlé de fils d'acier à une plage de température prédéterminée, et à l'élimination de chaleur contrôlée pendant la transformation de l'austénite en perlite. Un fil d'acier ayant un excellent durcissement par écrouissage est obtenu.
