Abstract

L'invention concerne l'usinage des métaux par pression. Le procédé faisant l'objet de l'invention est du type comprenant le façonnage successif d'une brame I par passage de celle-ci à travers une série de calibres constitués chacun par plusieurs cannelures contigües ménagées sur les cylindres de laminage 2,3, avec obtention d'une série de demi-produits liés entre eux par des raccords suivant la largeur, suivie d'une séparation desdits demi-produits les uns des autres, et est caractérisé en ce que pour ladite séparation on provoque un glissement relatif des demi-produits contigus, en faisant agir le calibre essentiellement sur l'une des faces desdits demi-produits sous un angle différent de 90 degrés par rapport à l'axe du cylindre, cette séparation étant exécutée quand l'épaisseur des raccords reliant les demi-produits atteint une valeur comprise sensiblement entre 1/100 et 3/10 de la hauteur du calibre. L'invention s'applique notamment à la fabrication de demi-produits profilés dans une machine de coulée continue combinée avec un laminoir.
