Abstract

EL FUNCIONAMIENTO CONVENCIONAL DE UN HORNO DE CUPULA SIN CARBON DE COK NECESITA QUE SE PRODUZCA UN BAJO VOLUMEN DE ESCORIAS, A CAUSA DEL HECHO DE QUE NO HAY QUE QUITAR CENIZAS DEL CARBON DE COK DESDE LA CARGA, Y DEL HECHO DE QUE EL FLUJO AÑADIDO A LA CARGA PARA FORMAR LA ESCORIA SE CONSUME EN EL REVESTIMIENTO DEL HORNO, Y EN EL LECHO DE ESFERAS REFRACTARIAS. HACIENDO FUNCIONAR EL HORNO CON VOLUMENES PEQUEÑOS DE ESCORIA HACE QUE LAS ESCORIAS AUMENTEN Y PUEDAN PROVOCAR EL BLOQUEO DE LA SALIDA PARA LAS ESCORIAS Y DE LA CAJA PARA LA COLADA. LA INVENCION AÑADE MAS MATERIALES DE FLUJO QUE LO QUE ES CONVENCIONAL, PREFERIBLEMENTE INCLUYENDO SILICE EN FORMA DE BOTELLAS ROTAS, PARA INCREMENTAR DE FORMA DELIBERADA EL VOLUMEN DE LA ESCORIA, MEJORANDO EL FLUJO. DEBE TENERSE CUIDADO DE NO AÑADIR DEMASIADOS MATERIALES FORMADORES DE ESCORIA.
