Abstract

EN UN PROCEDIMIENTO Y EN UNA DISPOSICION PARA LA FABRICACION DE METAL LIQUIDO (4) A PARTIR DE PARTICULAS DE OXIDOS METALICOS DE GRANULADO FINO, ESTAS SON SOPLADAS CONJUNTAMENTE CON GAS DE REDUCCION CALIENTE CONTRA UNA CAPA FILTRANTE DE MATERIAL SUELTO (9) CALIENTE DE PIEZAS DE CARBON Y/O DE CERAMICA, EN EL QUE UNA PARTE IMPORTANTE DE PARTICULAS QUEDAN RETENIDAS POR LA CAPA FILTRANTE, Y FINALMENTE SE REDUCEN POR MEDIO DEL GAS DE REDUCCION. POR MEDIO DEL SOPLADO DE UN GAS CONTENIENDO OXIGENO CONTRA LA CAPA FILTRANTE (9), SE PRODUCE DELANTE DE ELLA UNA LLAMA DE ALTA TEMPERATURA, Y SE DERRITEN LAS PARTICULAS METALIZADAS RETENIDAS EN LA CAPA FILTRANTE. ESTAS ATRAVIESAN EN ESTADO LIQUIDO LA CAPA FILTRANTE (9) HASTA UNA CAMARA DE ALOJAMIENTO (3) PARA EL METAL LIQUIDO.
