Abstract

Настоящее изобретение относится к способу получения горячего металла, в соответствии с которым гранулированное сырье, содержащее оксид железа, подвергают частичному восстановлению до восстановленной смеси в присутствии углеродсодержащего восстановителя в реакторе с псевдоожиженным слоем при температуре, составляющей по меньшей мере 850°С, и через систему вывода, возможно после разделения магнитных и немагнитных компонентов способом горячего магнитного разделения, восстановленную смесь направляют в установку восстановительной плавки. Для оптимизации потребления энергии восстановленную смесь охлаждают до температуры, составляющей от 600 до 800°С, в теплообменном устройстве и после этого подают в плавильную установку, в которой в качестве охлаждающей среды применяют предварительно подогретый технологический газ.
