Abstract
PARA MEJORAR EL FUNCIONAMIENTO, EN ESPECIAL PARA POSIBILITAR UNA UTILIZACION UNIVERSAL, PARA QUE SE PUEDA PURIFICAR EN UN UNICO REACTOR METAL EN BRUTO TANTO LIQUIDO COMO SOLIDO, EN ESPECIAL HIERRO, SE FABRICA EL RECIPIENTE DE UN REACTOR (1) EN FORMA DE CONVERTIDOR CON UN ESPACIO RELATIVAMENTE GRANDE POR ENCIMA DE LA COLADA (7) Y DE UNA ESCORIA (8) POR ENCIMA DE ELLA. PARA RETIRAR LA ESCORIA (8) POR UN CANAL (18{SUP,''}) QUE SE PUEDE CERRAR, SE GIRA EL AGREGADO DE FUNDICION ALREDEDOR DE UN PUNTO (20) UNOS 8 . PARA RETIRAR TOTALMENTE LA COLADA (7) POR UN CANAL (17{SUP,''} QUE SE PUEDE CERRAR Y QUE SE ENCUENTRA EN LA ZONA DEL FONDO DEL AGREGADO DE FUNDICION, SE PUEDE GIRAR ALREDEDOR DE UN PUNTO (19) UNOS 30 . UNA BOBINA MAGNETICA (16) ALIMENTADA POR CORRIENTE CONTINUA Y QUE RODEA AL APARATO (1) SIRVE PARA LA AMORTIGUACION MAGNETICA DE LOS MOVIMIENTOS DE LA COLADA (7) Y/O DE LAS ESCORIAS (8) DENTRO DEL APARATO. EN EL FUNCIONAMIENTO DEL CONVERTIDOR SE SUSTITUYE UN ELECTRODO DE GRAFITO (5) UTILIZADO EN EL FUNCIONAMIENTO DLE ARCO ELECTRICO POR UNA CONDUCCION DE GAS, QUE AÑADE OXIGENO A PRESION.
