Ingot travel control in mould during electroslag remelting - by maintaining constant level of molten metal via electronic monitor circuit

Relative movement of the cast ingot and the mould is adjusted by monitoring the level of the molten metal in the mould. This is achieved by insulating one part of the mould and connecting it to an electronic circuit measuring the actual voltage (Va) between the mould and the ingot or between a movin...

Zusammenfassung:Relative movement of the cast ingot and the mould is adjusted by monitoring the level of the molten metal in the mould. This is achieved by insulating one part of the mould and connecting it to an electronic circuit measuring the actual voltage (Va) between the mould and the ingot or between a moving core mandrel and the ingot. Va is compared with a desired voltage (Vref), and any difference is used to alter the speed at which the ingot is lowered out of the mould or at which a core mandrel is fed upwards into the mould. Metallurgical quality of solid or tubular ingots is improved. UNE PARTIE 10 DE LA LINGOTIERE 2 EST ELECTRIQUEMENT ISOLEE DU LINGOT 1 ET D'UNE AUTRE PARTIE DE LA LINGOTIERE ASSURANT LA FORMATION DE CE LINGOT ET D'UNE AUTRE PARTIE DE LA LINGOTIERE ASSURANT LA FORMATION DE CE LINGOT, EST SITUEE AU-DESSUS DU NIVEAU 3 DU BAIN DE METAL ET EN CONTACT AVEC LE BAIN DE LAITIER 4. ON CONTROLE LE NIVEAU 3 PAR MESURE DE LA TENSION ENTRE LA PARTIE 3 ET LE LINGOT , PUIS ON LA COMPARE A LA VALEUR IMPOSEE ET, S'IL Y A UN DESACCORD, ON MODIFIE CONFORMEMENT LA VITESSE DE DEPLACEMENT RELATIF DU LINGOT ET DE LA LINGOTIERE DANS LE SENS ASSURANT LE RETABLISSEMENT DU NIVEAU 3 IMPOSE.LA PARTIE ELECTRIQUEMENT ISOLEE DE LA LINGOTIERE PEUT ETRE UN INSERT CONDUCTEUR 10 LOGE DANS SA PAROI.L'INVENTION EST UTILISABLE POUR L'ELABORATION DE LINGOTS CREUX ET PLEINS PAR REFUSION SOUS LAITIER ELECTROCONDUCTEUR.
