Claims (1)

Способ получения чугуна или стального расплава из кускового железосодержащего материала, заключается в том, что последний восстанавливается в восстановительной шахтной печи с помощью газа- восстановителя, причем полученные частицы губчатого железа расплавляют в плавильном реакторе при подводе угля и кислородсодержащего газа с одновременным образованием газа- восстановителя, который подводится в зону восстановления шахтной печи. Для того, чтобы можно было бы, наряду с загружаемым материалом применять тонкодисперсную руду или пылевидную руду, например, оксидную железистую пыль, выделяюшуюся в процессе металлургического производства, тонкодисперсную руду или пылевидную руду вместе с твердыми носителями углерода вводят в одну пылеугольную горелку плавильного реактора и проводят реакцию сгорания при соотношении ниже стехиометрического.A method of producing cast iron or steel melt from lumpy iron-containing material is that the latter is reduced in a reduction shaft furnace using a reducing gas, the resulting sponge iron particles being melted in a melting reactor by supplying coal and an oxygen-containing gas with the formation of a reducing gas, which is fed into the recovery zone of the shaft furnace. In order to be able to use, along with the feed material, finely dispersed ore or pulverized ore, for example, oxide ferrous dust released during the metallurgical production, finely dispersed ore or pulverized ore together with solid carbon carriers are introduced into one pulverized coal burner of the melting reactor and carried out combustion reaction at a ratio below stoichiometric.
