Abstract
Ce dispositif est du type comprenant une goulotte dirigée vers le jet de métal et servant à y introduire les substances d'addition, en particulier des substances d'alliage. Selon l'invention, la goulotte 9 est montée mobile entre une position de repos A où toute la goulotte se trouve sous un recouvrement, formée par exemple par le plancher 8 d'une plate-forme de travail 7 installée à côté d'un convertisseur basculant 2, et une position de travail B ou C où l'extrémité postérieure de la goulotte se trouve dans la région de la sortie d'un appareil d'alimentation 21 et où son extrémité antérieure se trouve à proximité immédiate du jet de métal 3 tombant dans une poche de coulée 4. L'invention est notamment applicable à la coulée en poche
