Abstract

Способ производства стали включает получение жидкой стали и сталеплавильного шлака в процессе ее изготовления, причем сталеплавильный шлак содержит элементы железа и флюса, и после этого получение жидкого железа в ванне расплава на основе способа прямого плавления, который использует значительную часть сталеплавильного шлака как часть потребностей в переплавном материале для способа прямого плавления. Также раскрывается способ прямого плавления. Способ включает предварительную обработку металлосодержащего материала, который содержит сталеплавильный шлак, а после этого прямое плавление жидкого железа с использованием предварительно обработанного металлосодержащего материала как части металлосодержащего материала, необходимого для способа.
