Abstract

LAS INCLUSIONES SOLIDAS, NO METALICAS NO DESEADAS SE RETIRAN DE LOS METALES FUNDIDOS EN UN RECIPIENTE REVESTIDO DE UN MATERIAL REFRACTARIO A BASE DE BORBOTEAR GAS INERTE HACIA ARRIBA A TRAVES DEL METAL. LA INVENCION PRESENTA UN BLOQUE DE TOBERA PERMEABLE AL GAS (16) CON UNA FORMA TAL QUE PUEDE RECIBIR A UNA TOBERA (17) CON UN AGUJERO PASANTE COLOCADO EN EL CENTRO Y QUE SE PUEDE FIJAR DE MANERA HERMETICA EN EL REVESTIMIENTO REFRACTARIO (13) DE UN RECIPIENTE (10) PARA RECIBIR AL METAL FUNDIDO, TENIENDO EL BLOQUE DE TOBERA (16) UN CANAL RECEPTOR DEL GAS (18) PARA QUE SE EXTIENDA ALREDEDOR DE LA TOBERA (17) Y ELEMENTOS PARA CONECTAR EL CANAL RECEPTOR DEL GAS (18) A UNA FUENTE DE GAS.SOLID, NON-DESIRED, NON-METALLIC INCLUSIONS ARE REMOVED FROM METALS MELTED IN A CONTAINER COATED WITH REFRACTORY MATERIAL BASED ON INVERT GAS BUBBLING THROUGH THE METAL. THE INVENTION PRESENTS A GAS PERMEABLE NOZZLE BLOCK (16) IN A FORM SUCH AS MAY RECEIVE A NOZZLE (17) WITH A THROUGH HOLE PLACED IN THE CENTER AND WHICH CAN BE FIXED HERMETICALLY ON THE REFRACTORY LINING (13) A CONTAINER (10) TO RECEIVE THE CAST METAL, HAVING THE NOZZLE BLOCK (16) A GAS RECEIVING CHANNEL (18) TO EXTEND AROUND THE NOZZLE (17) AND ELEMENTS TO CONNECT THE GAS RECEIVING CHANNEL (18) TO A GAS SOURCE.
