Abstract

The method for continuous manufacture of metal profiled sections consists in using a coil of metal wire successively heated by Joule effect and by induction before passing into the different rolling heads intended to give it the desired profile.

Description

La présent invention a pour objet un procédé de fabrication en continu des profilés métalliques. La technique antérieure consistait à partir de barres dont la longueur était habituellement comprise entre 2 et 5 mètres qui étaient d'abord chauffées par un moyen quelconque jusqu'à une température de 1200 degrés C environ, puis à les présenter successivement dans trois ou quatre tettes de laminage afin d'obtenir le profil souhaité.The present invention relates to a continuous manufacturing process for metal profiles. The prior art consisted of bars, the length of which was usually between 2 and 5 meters, which were first heated by any means to a temperature of about 1200 degrees C, then presented successively in three or four tettes to obtain the desired profile.

Ce procédé avait pour inconvénient son caractère discontinu.This process had the disadvantage of being discontinuous.

L'objet de la présente invention est de remplacer le procédé discontinu par un procédé continu dont les effets sont - rapidité d'élaboration, - économie d'énergie résultant de la mise en oeuvre de nouveau procédés de chauffage.The object of the present invention is to replace the discontinuous process with a continuous process the effects of which are - speed of preparation, - energy saving resulting from the implementation of new heating processes.

Un exemple de réalisation selon la figure 1 présente un système continu où 1 est le dévidoir, 2 le pré-dresseur.An exemplary embodiment according to Figure 1 shows a continuous system where 1 is the reel, 2 the pre-blocker.

Un dispositif de chauffage par effet joule consistant à faire parcourir le fil avant laminage par ul courant électrique dont l'effet est d'en produire l'échauffement jusqu'à une température d'environ 800 à 900 degrés C est représenté en 3.A Joule effect heating device consisting in passing the wire through an electric current before rolling, the effect of which is to produce heating thereof up to a temperature of approximately 800 to 900 degrees C is shown in 3.

Ce système de chauffage 3, est suivi par un inducteur 4 parcouru par us courant alternatif à fréquence élevée dont le but est d'amener le fil jusqu'à une température de 1100 à 1200 degrés C et de réaliser une homogénisation de la chauffe précédente.This heating system 3 is followed by an inductor 4 traversed by us alternating current at high frequency whose purpose is to bring the wire to a temperature of 1100 to 1200 degrees C and to achieve homogenization of the previous heating.

Le fil est alors guidé dans quatre têtes de laminage 5, 6, 7 et 8 destinées à lui donner le profil souhaité. Un dispositif de coupe (9) sectionne alors le profilé à la longueur souhaitée. The wire is then guided in four rolling heads 5, 6, 7 and 8 intended to give it the desired profile. A cutting device (9) then cuts the profile to the desired length.
