Abstract

UNA TOBERA DE INMERSION (10) PARA LA FUNDICION CONTINUA DE METALES TIENE UN CUERPO DE LA TOBERA ALARGADO (12) HECHO DE UN MATERIAL REFRACTARIO PERMEABLE AL GAS, POROSO. EL CUERPO DE LA TOBERA TIENE UN CONDUCTO (18) QUE SE EXTIENDE LONGITUDINALMENTE A SU TRAVES Y UNA SUPERFICIE INTERIOR (20) QUE DEFINE EL CONDUCTO. EL CUERPO DE LA TOBERA PUEDE TENER TAMBIEN UNA SUPERFICIE EXTERIOR QUE DEFINE UN PERFIL DEL CUERPO PREDETERMINADO Y CANALES (24, 26, 28, 30) HECHOS EN LA SUPERFICIE EXTERIOR (16) DEL CUERPO DE LA TOBERA. EL CUERPO DE LA TOBERA SE ENCUENTRA COLOCADO DENTRO DE UN ALOJAMIENTO METALICO (14) QUE TIENE UNA SUPERFICIE INTERIOR (32) DE UN TAMAÑO TAL QUE SE AJUSTA SUSTANCIALMENTE AL PERFIL DEL CUERPO DE LA TOBERA. EL ALOJAMIENTO QUEDA ASEGURADO AL CUERPO DE LA TOBERA MEDIANTE UN MORTERO REFRACTARIO (40) QUE FORMA UNA CAPA RELATIVAMENTE HERMETICA AL AIRE RIGIDA ENTRE EL ALOJAMIENTO Y EL CUERPO DE LA TOBERA, EN DONDE LOS MEDIOS DE CANAL FORMAN PASOS INTERNOS EN LA TOBERA. HAY UN PUERTO (34)EN EL ALOJAMIENTO EN REGISTRO CON LOS CANALES QUE HAY EN EL CUERPO DE LA TOBERA. EL PUERTO SE PUEDE CONECTAR A UNA FUENTE DE GAS INERTE, QUE SE PUEDE ACTIVAR PARA HACER QUE EL GAS ENTRE EN LOS PASOS Y EN EL MATERIAL POROSO REFRACTARIO.
