The invention concerns a flux-cored wire for introducing additives into a molten metal bath comprising a metal sheath (5) containing an additive (6), which metal sheath is covered with an envelope (7) which, being combustible but without unwanted residues, momentarily delays heat propagation towards the flux-cored wire core. Said flux-cored wire is characterised in that above said combustible envelope, a metallic protection encloses the assembly formed by the additive, the metal sheath and the combustible envelope.
L'invention se rapporte à un fil fourré pour l'introduction d'additifs dans un
bain de métal en fusion comprenant une
gaine (5) métallique contenant un additif (6) laquelle gaine métallique est
recouverte par une enveloppe (7) qui, combustible sans
laisser de résidus gênants, retarde momentanément la propagation de la chaleur
vers le coeur du fil fourré ce fil fourré étant caractérisé
en ce que qu'au dessus de cette enveloppe combustible, une protection
métallique enserre l'ensemble constituée par l'additif, la gaine
métallique et l'enveloppe combustible.
