Abstract

Dans un fil fourré destiné à l'introduction d'additifs dans des bains de métal, il est utile d'augmenter le taux de remplissage pour diminuer la longueur utile du fil et en même temps la durée nécessaire pour introduire une quantité déterminée d'additif dans le bain, tout en assu­ rant que le diamètre du fil soit assez réduit pour que le fil se laisse bobiner sur des rouleaux d'un diamètre con­ ventionnel. In a cored wire intended for the introduction of additives in metal baths it is useful to increase the rate filling to reduce the useful length of the wire and at the same time the time required to introduce a specified amount of additive in the bath, while assu rant that the diameter of the wire is reduced enough so that the wire can be wound on rollers with a con diameter optional.

Le fil fourré composite suivant l'invention est carac­ térisé en ce qu'il comprend notamment une gaíne métal­ lique constituée par un feuillard mince dont les bord sont recourbés de façon à ce qu'il forme un profil de section sensiblement plate, ainsi qu'un additif enfermé à l'intérieur de la gaíne, l'additif étant entouré du moins partiellement par une enveloppe en matière synthétique organique ou métallique sous la forme d'un feuillard qui présente une épaisseur inférieure à 100 microns. Suivant l'invention la hauteur du fil plat est de préférence de l'ordre de 10-12 mm et sa largeur correspond au moins au triple de ladite hauteur. The composite cored wire according to the invention is charac terized in that it includes in particular a metal sheath lique consisting of a thin strip whose edges are bent so that it forms a profile of substantially flat section, as well as an additive enclosed in inside the shaft, the additive being surrounded by at least partially by a plastic casing organic or metallic in the form of a strip which has a thickness of less than 100 microns. following the invention the height of the flat wire is preferably around 10-12 mm and its width corresponds to at least three times that height.
