Abstract

PASSAGE DU METAL FONDU AU TRAVERS DE FILTRES SUCCESSIFS DONT LE PREMIER COMPORTE DES TRAJETS PREFERENTIELS A CONTRE-COURANT POUR LE GAZ INJECTE DANS LE METAL FONDU. LE METAL FONDU ARRIVE PAR LE CANAL 18 DANS L'APPAREIL 10 DIVISE EN DEUX CHAMBRES 14, 16 PAR LA CHICANE 12. LES CHAMBRES 14 ET 16 ONT DES MONTURES 26, 28 EN FORME DE TREMIE QUI PORTENT DES FILTRES 30 ET 32. LE FILTRE 30 EST PERCE D'OUVERTURES 50. LA BASE DE LA CHAMBRE 14 COMPORTE UNE PLAQUE DE DISTRIBUTION PAR OU L'ON FAIT BARBOTER UN GAZ DONT LES BULLES TRAVERSENT LE METAL FONDU. CELUI-CI PASSE AU TRAVERS DES FILTRES 30 ET 32 ET IL S'ECOULE PAR LE CANAL 20. DANS LE FILTRE 30, IL SE PRODUIT UN ECOULEMENT A CONTRE-COURANT DU GAZ ET DU METAL FONDU.
