Abstract

Способ формирования огнеупорного агента в огнеупорной массе печи для использования в процессе обогащения титановой руды включает следующие стадии: формируют агломераты, содержащие материалы на основе углерода и титановую руду, причем количество углерода агломератов достаточное для восстановления при повышенной температуре окиси железа в закись железа и образованию шлака, состоящего из оксида титана и оксида железа; агломераты вводят в углеродный слой печи с подвижным подом, при том, что печь с подвижным подом содержит огнеупорную футеровку, которая имеет первый слой, что содержит глинозем и двуокись циркония с содержанием от около 90 до около 99 масс. % глинозема и от около 1 до около 10 мас. % двуокиси циркония относительно общей массы первого слоя; агломераты нагревают в печи с подвижным подом до температуры, достаточной для восстановления и расплава агломератов, чтобы получить обогащенный оксидом титана жидкий шлак, который приводят в контакт с огнеупорной футеровкой, чтобы получить второй слой, содержащий огнеупорный агент, который является продуктом реакции шлака, глинозема и двуокиси циркония; причем второй слой формируют между шлаком и первым слоем. Общее содержание оксида кальция, оксида магния, оксида иттрия и оксида церия составляет менее чем 1 мас. % в отношении общей массы огнеупорной массы.
