Abstract

L'invention porte sur un appareil pour traiter un laitier métallurgique, lequel appareil est associé à un four de fusion (11) ayant au moins une chambre de fusion (13) et une ouverture de décrassage (15) à partir de laquelle un courant de laitier (12) sort vers un point de collecte en dessous, et lequel comprend un élément tubulaire (18) ayant une extrémité de sortie, et des moyens d'alimentation pneumatiques (20), coopérant avec au moins un réservoir (21) contenant des additifs d'inertisation (22). Les moyens d'alimentation pneumatiques (20) coopèrent avec l'élément tubulaire (18) et avec le réservoir (21) pour transférer les additifs d'inertisation (22) à partir du réservoir (21) vers l'extérieur de l'extrémité de sortie dudit élément tubulaire (18), où il y a au moins une buse de sortie (19, 119, 219) pour projeter les additifs d'inertisation (22) dans le courant de laitier (12) avec une énergie cinétique désirée.
