Abstract

DONDE EL METODO COMPRENDE: INYECTAR IMPACTOS DE AIRE DISCRETOS CON INTERVALOS DE TIEMPO REGULADOS A UNA PRESION ENTRE 70 Y 100 PSI Y A UNA VELOCIDAD ENTRE 195 Y 300 m/s, A TRAVES DE UNA TOBERA DE SOPLADO DE AIRE ENRIQUECIDO O GASES DE REACCION DE FORMA QUE LOS IMPACTOS PENETREN DENTRO DEL BANO EN FUNDICION PRESENTE EN LOS REACTORES O CONVERTIDORES, PARA PROVOCAR EL ROMPIMIENTO DE ACRECIONES OBSTRUCTIVAS QUE TAPAN EL FLUJO DEL AIRE O GAS A TRAVES DE LA TOBERA; Y FORMAR CON LOS IMPACTOS, PRODUCTO DEL ENFRIAMIENTO OCASIONADO POR LA PENETRACION DE LOS MISMOS, UNA ACRECION DIRIGIDA CON MATERIAL DEL BANO EN FUNDICION QUE SE SOLIDIFICA POR EFECTO DEL ENFRIAMIENTO, LOGRANDO QUE LA FORMACION DE ACRECION DIRIGIDA CONSTITUYA EL ALARGAMIENTO NATURAL DEL TUBO QUE COMPRENDE A LA TOBERA DESDE LA PARED INTERIOR DE LOS REACTORES O CONVERTIDORES, Y ASI PERMITIR QUE EL AIRE PENETRE MAS PROFUNDO EN DICHO BANO, A UNA DISTANCIA EN DONDE SE GENERA OLEAJE DE ESTE ULTIMO ALEJADO DE LA PARED CON MATERIAL REFRACTARIO DE LOS REACTORES O CONVERTIDORES EVITANDO EL DESGASTE DE DICHO REFRACTARIO, Y EL OLEAJE TIENDA A ELIMINAR LAS POSIBLES ACRECIONES OBSTRUCTIVAS QUE SE PUEDAN FORMAR. EL SISTEMA INCLUYE: a) UN RECEPTACULO CON CAPACIDAD PARA ALMACENAR AIRE COMPRIMIDO ENTRE 40 Y 60 LITROS Y A UNA PRESION ENTRE 70 Y 10 psi; b) UNA VALVULA DE PISTON PARA EVACUAR EL AIRE DE (a) A UNA VELOCIDAD ENTRE 263 Y 328 m/s; Y, c) UN MEDIDOR DE FLUJO, TAL COMO UN SENSOR OPTICO, EN LA TOBERA PARA OBSERVAR ALGUNA OBSTRUCCION
