FIELD: metallurgy.
SUBSTANCE: invention relates to the field of metallurgy, more particularly, to oxygen converter steel production. A converter includes a body with refractory lining, a water-cooled lance for blowing oxygen, a gas exhaust duct and an offtake. The offtake is a ring type with a rotary hearth that has refractory surface with scrap metal and coal thereupon, drive means for the said rotary hearth, a slide gate for separating a wast gas hot stream, a refractory fixed roof with an oxygen lance. The refractory fixed roof has openings for charging scrap metal, coal, discharging hot scrap metal, an intake opening for directing waste gases into the ring offtake and an exhaust opening for directing waste gases from the ring offtake.
EFFECT: invention application may reduce hot metal take and steel melting cycle.
