Abstract

L'invention concerne un procédé de production d'un tuyau sans soudure fini à chaud, en acier à déformabilité réduite, notamment de l'acier pour paliers à roulement. De l'acier liquide désoxydé, prétraité et dégazé correspondant à la composition chimique requise, est coulé en continu et présente une section transversale quelconque. Après séparation de la barre, la pièce d'acier coulée est soumise à un processus de formage, une fois fractionnée en longueurs appropriées à l'utilisation finale. Selon l'invention, les tronçons ainsi obtenus sont portés à la température de formage, sans formage préalable, c.-à-d. à l'état de pièce coulée et sans traitement thermique (homogénéisation), puis sont acheminés jusqu'à une usine de production de tuyaux.
