Abstract

PROCEDIMIENTO Y SISTEMA DE CONTROL PARA LA CONVERSION DE MINERAL DE HIERRO EN NODULOS DE ALTO CONTENIDO EN HIERRO. EL PROCEDIMIENTO CONSISTE EN CARGAR UN REACTOR (1) CON UNA PARTIDA DE MINERAL DE HIERRO; SOMETER A ESTE MINERAL A UN PROCESO DE REDUCCION INSUFLANDO EN EL REACTOR GASES CALIENTES DE REDUCCION Y GASES DE ENFRIAMIENTO A TRAVES DE LAS BOCAS (11, 12) RESPECTIVAS DEL MISMO; Y VERIFICAR SIMULTANEAMENTE LOS AUMENTOS DEL CONTENIDO DE HIERRO Y EL CONTROL DE TEMPERATURA EN EL MINERAL A MEDIDA QUE LOS GASES LO ATRAVIESAN, PARA SALIR AL EXTERIOR POR LAS BOCAS (13) INFERIORES DEL REACTOR. CUANDO TODO EL MINERAL SE HA TRANSFORMADO EN NODULOS, EL PROCESO SE TERMINA. EL SISTEMA DE CONTROL SE LLEVA A EFECTO INSTALANDO UNA SERIE DE BOBINAS DETECTORAS (14, 15, 16, 17). MIDIENDO LA INDUCTANCIA DE ESTAS BOBINAS, QUE VARIA CON EL INCREMENTO DE HIERRO EN EL MINERAL, PODREMOS DETERMINAR EL GRADO DE TRANSFORMACION VERDADERO EN CADA ZONA.
