Abstract RU 2667929 C1

FIELD: metallurgy.

SUBSTANCE: invention relates to the field of ferrous metallurgy, in particular to the production of a semi-finished product in the form of a semi-finished product for steelmaking. Said semi-product is made in the form of a steel capsule filled with iron oxides with an iron content of at least 55 % and moisture content of no more than 12 % and scrap metal not exceeding 250 mm, the mass fraction of iron oxides in the intermediate being 10–70 %.

EFFECT: invention makes it possible to achieve the best conditions for the dissociation of iron oxides in the process of steel smelting, to reduce the consumption of scrap metal, to improve the quality of the steel produced and to reduce its cost.
