Abstract

LA INVENCION SE REFIERE A UN ANODO QUE MUESTRA UN COMPORTAMIENTO DE DESGASTE REGULAR DE FORMA APROXIMADA LOCAL Y ES ADAPTABLE EN FORMA SENCILLA SEGUN DISTINTAS FORMAS DE EJECUCION DE HORNOS DE ARCO ELECTRICO DE CORRIENTE CONTINUA. PARA ELLO SE ENCUENTRAN DISPUESTAS MULTIPLES CHAPAS DE CONTACTO SIMETRICAS SOBRE UNA CHAPA DE FONDO CONDUCTORA ELECTRICA. EL FLUJO DE CORRIENTE ELECTRICA SE ASEGURA SOBRE UN CARRIL QUE SE ENCUENTRA EN LA CARA EXTERIOR DEL HORNO Y SOBRE UN ANILLO DE COBRE QUE RODEA UNA MASA APISONADA NO CONDUCTORA ELECTRICA EN EL INTERIOR DEL REVESTIMIENTO DEL HORNO, DONDE LA CHAPA DE FONDO, QUE SE ENCUENTRA EN LA PLACA DE PIE DEL SEGMENTO DE CONTACTO INDIVIDUAL Y SOBRE LAS PLACAS DE CHAPAS EXISTENTES SE ASEGURAN HASTA EN SITUACION DE COLADA. LAS PLACAS DE CHAPAS ESTAN RODEADAS POR MASAS APISONADAS INCLUSO NO CONDUCTORAS ELECTRICAS Y SE ELEVAN SOLO CON SU SUPERFICIE FRONTAL SUPERIOR EN EL BAÑO DE FUSION.
