摘要
FIELD: metallurgy.;SUBSTANCE: method involves solid charge feeding, hot-metal charging, further oxygen purging of the bath, additing slag-forming materials and solid oxidizers. Metal scrap and semi-finished product consisting of an iron-carbon alloy and iron oxides for metal conversion are used as the solid charge. The semi-finished product for metal conversion is produced in the form of compressed packets, inside which capsules filled with iron oxides with the iron content of at least 55% and moisture of no more than 12% are put prior to compression. Mass fraction of oxides in the packet is 35-45%, and the mass fraction of compressed packets is 20-45% of the total weight of the scrap metal and compressed packets. Containers of ferrous materials are used as capsules.;EFFECT: reduced scrap metal consumption and reduced steelmaking cost.;1 tbl, 1 ex
