Abstract

L'INVENTION APPORTE UN PERFECTIONNEMENT AU CIRCUIT POUR LE REFRIGERANT A L'INTERIEUR DE L'ELECTRODE. SELON L'INVENTION, LE RACCORD EN GRAPHITE ENTRE LA PARTIE METALLIQUE SUPERIEURE ET LA PARTIE INFERIEURE CONSOMMABLE EST REMPLACE PAR UN DOUBLE RACCORD FILETE MALE 59 EN METAL QUI EST CREUX MAIS FERME EN BAS ET OUVERT EN HAUT, ET LE TUBE CENTRAL 37 EST PLUS LONG EN BAS ET FAIT AXIALEMENT SAILLIE DANS LE RACCORD 59. LE REFRIGERANT QUI DESCEND PAR LE TUBE 37 REMONTE DONC MAINTENANT DANS LE RACCORD, EN LE REFROIDISSANT, AVANT DE SE DIRIGER RADIALEMENT VERS L'EXTERIEUR ET VERS LE BAS POUR ENTRER DANS LE PASSAGE ANNULAIRE ENTRE LES PAROIS 22 ET 24.
