Abstract

Procédé pour la fabrication de rails dans lequel, au sortir du laminoir à chaud, on soumet le rail en défilement continu à un refroidissement rapide et on refroidit ensuite le rail jusqu'à la température ambiante; on règle la longueur de la rampe, la vitesse de défilement du rail et la densité moyenne des flux calorifiques appliqués au bourrelet, à l'ame et au patin pour que d'une part, les propriétés mécaniques finales dans le bourrelet soient obtenues alors que, à la sortie de ladite rampe, moins de 60 % de la section du bourrelet ait subi la transformation allotropique austénite-perlite et que d'autre part, les différences d'allongement entre le bourrelet et l'ame et entre le bourrelet et le patin soient minimisées.
