Abstract

SE DESCRIBE UN DISPOSITIVO PARA INYECTAR GAS EN UN METAL FUNDIDO, POR EJEMPLO ALUMINIO FUNDIDO, EN LA CAMARA DE UN HORNO. EL DISPOSITIVO COMPRENDE: A) UN APARATO AGITADOR QUE TIENE UN DEPOSITO SEPARADO DE LA CAMARA DEL HORNO, UNA PARTE DE CONEXION CON UN ORIFICIO QUE CONECTA EL INTERIOR DEL HORNO Y EL DEPOSITO PARA EL PASO DEL METAL FUNDIDO ENTRE ELLOS A TRAVES DE LA PARTE DE CONEXION, MEDIOS GENERADORES DE VACIO/PRESION CONECTADOS AL INTERIOR DE LA CAMARA DEL DEPOSITO DE FORMA SUCESIVA Y ALTERNATIVA PRODUCIR EN LA MISMA UN VACIO PARA ASPIRAR EL METAL FUNDIDO A SU INTERIOR DESDE LA CAMARA DEL HORNO Y UNA PRESION POSITIVA PARA EXPELER EL METAL FUNDIDO AL INTERIOR DE LA CAMARA DEL HORNO A TRAVES DEL ORIFICIO EN FORMA DE UN CHORRO DE ALTA VELOCIDAD, Y B) MEDIOS INYECTORES DE GAS ADAPTADOS PARA INYECTAR GAS AL INTERIOR DEL CHORRO DE ALTA VELOCIDAD DE FORMA QUE EL GAS SE DIVIDE EN UN GRAN NUMERO DE PEQUEÑAS BURBUJAS QUE SE HACEN CIRCULAR A TRAVES DE LA CAMARA DEL HORNO JUNTO CON EL CHORRO.
