Abstract

Изобретение относится к черной металлургии. Способ термической обработки твердых материалов, содержащих оксид железа включает нагревание мелкозернистых твердых материалов до температуры от 450 до 950 °С в реакторе с псевдоожиженным слоем посредством двух потоков газа или газовых смесей, причем первый поток газа либо газовой смеси вводят снизу в область смесительного пространства реактора через газоподводящую трубу при этом газоподводящая труба по крайней мере частично окружена стационарным кольцевым псевдоожиженным слоем, который сжижают вторым потоком газа, который являет
