Abstract

Appareillage de dosage de matières ou mélanges de matières sous forme pulvérulente et/ou granuleuse, comportant au moins un récipient et des dispositifs de dosage. Le récipient 3 comporte une partie inférieure 5 de section décroissante vers le bas et sur le fond de laquelle est disposée au moins une buse 12 au-dessus de laquelle est placé un éjecteur 13, la buse 12 étant reliée à un conduit de transport de mélange 14. Application à l'introduction de matières d'alliage ou de traitement dans des bains métalliques, notamment des bains d'acier.Apparatus for metering materials or mixtures of materials in powder and / or granular form, comprising at least one container and metering devices. The container 3 has a lower part 5 of decreasing section downwards and on the bottom of which is arranged at least one nozzle 12 above which is placed an ejector 13, the nozzle 12 being connected to a mixture transport duct 14. Application to the introduction of alloying or treatment materials into metal baths, in particular steel baths.
