Abstract

Изобретение относится к отрасли металлургии. Способ производства железа включает прямое восстановление железорудных окатышей или комков кондиционированным восстановительным газом, содержащим сернистые соединения и / или диоксид углерода. При этом указанный восстановительный газ получают путем прохождения обедненного газа от установки прямого восстановления с последующей его очисткой, охлаждением и обогащением. Причем указанный восстановительный газ в процессе очистки, охлаждения и обогащения делится на пять потоков, и именно пятый поток в дальнейшем и используется в качестве кондиционированного восстановительного газа.
