Abstract

SE FACILITA UN CONJUNTO DE TOBERA REFRACTARIA (1) QUE IMPIDE, DE UN MODO EFICAZ, LA ACUMULACION DE DEPOSITOS DE ALUMINA ALREDEDOR DE SU BORDE SUPERIOR, EN EL QUE RECIBE UN REDONDO DE OBTURACION. EL CONJUNTO DE TOBERA INCLUYE UN CUERPO DE TOBERA REFRACTARIO (7) QUE TIENE UNA ZONA SUPERIOR (9) Y UNA ZONA INFERIOR (11). ATRAVESANDO AMBAS ZONAS, SUPERIOR E INFERIOR, SE EXTIENDE UN AGUJERO HUECO (13) QUE TIENE UN EXTREMO DE RECEPCION Y OTRO DE DESCARGA PARA LA RECEPCION Y DESCARGA DEL METAL FUNDIDO. UN DISTRIBUIDOR DE GAS INERTE (20) SE ENCUENTRA CIRCUNSCRITO A LA PARTE SUPERIOR DEL CUERPO DE LA TOBERA. UNA CAMISA (40) DE MATERIAL REFRACTARIO QUE OBSTRUYE EL PASO DEL GAS RECUBRE LAS PAREDES DEL AGUJERO HUECO Y DEFINE UNA PARTE DE ASIENTO EN LA ZONA SUPERIOR DEL AGUJERO HUECO. UNA VAINA METALICA (50) RODEA, DE MODO SUSTANCIAL, LA SUPERFICIE EXTERIOR DE LA PARTE SUPERIOR (9). EL GAS INERTE PRESURIZADO CONDUCIDO A LA ZONA SUPERIOR DEL CUERPO DE LA TOBERA, PERMEABLE AL GAS, POR EL CONJUNTO DE DISTRIBUCION DEL GAS, ES ORIENTADO POR LA CAMISA OBSTRUCTORA DEL GAS Y POR LA VAINA METALICA, DE MANERA QUE FLUYE DE PREFERENCIA A TRAVES DEL BORDE SUPERIOR DE LA PARTE SUPERIOR. LA CORRIENTE DE GAS INERTE RESULTANTE PROTEGE A LA PARTE DE ASIENTO DEL AGUJERO HUECO DEL OXIGENO DEL AMBIENTE, EVITANDO, EN CONSECUENCIA, LA ACUMULACION EN LA PARTE DE ASIENTO, DE DEPOSITOS DE ALUMINA, QUE PODRIAN INTERFERIR LA CAPACIDAD DEL REDONDO DE OBTURACION PARA CONTROLAR EL FLUJO DEL METAL DERRETIDO.
