Abstract

UNA PRIMERA CORRIENTE VERTICAL DE METAL FUNDIDO (21) FLUYE DE LA COLADA EN UN APARATO DE FUNDICION CONTINUA. UNA SEGUNDA CORRIENTE (27) COMPUESTA POR UNA ALEACION DE PARTICULAS SOLIDAS Y UN GAS PROTADOR NO OXIDANTE, ES DIRIGIDA A LA PRIMERA CORRIENTE POR UN INYECTOR (24). LAS DOS CORRIENTES (21,27) POSEEN AREAS ABIERTAS EXPUESTAS A LA ATMOSFERA QUE RODEA A LA COLADA. EL INYECTOR (24) ES ENFIRADO CON UN GAS NO OXIDANTE QUE FLUYE A TRAVES DE LA CAMISA DE ENFRIAMIENTO (31) DEL INYECTOR Y SE PRODUCE LA EXPULSION POR EL EXTREMO DE SALIDA (37) DEL INYECTOR (24). EL INTERIOR DE ESTE POSEE UN AREA CONVERGENTE (45) EN LA QUE CONVERGE LA SEGUNDA CORRIENTE (27), JUSTO ANTES DE DEJAR EL INYECTOR (24).
