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.THE INVENTION PROVIDES AN IMPROVEMENT TO THE CIRCUIT FOR THE REFRIGERANT INSIDE THE ELECTRODE. ACCORDING TO THE INVENTION, THE GRAPHITE CONNECTION BETWEEN THE UPPER METAL PART AND THE LOWER CONSUMABLE PART IS REPLACED BY A DOUBLE 59 MALE METAL FITTING WHICH IS HOLLOW BUT CLOSED AT THE BOTTOM AND OPENED AT THE TOP, AND THE CENTRAL TUBE 37 IS LONGER BOTTOM AND PROJECTED AXIALLY INTO THE FITTING 59. THE REFRIGERANT WHICH GOES DOWN THROUGH TUBE 37 NOW GOES UP INTO THE FITTING, COOLING IT, BEFORE MOVING RADIALLY OUTSIDE AND DOWN TO ENTER THE ANNULAR PASSAGE BETWEEN WALLS 22 AND 24.
