FIELD: chemistry.
SUBSTANCE: in compliance with proposed method, mix of raw stock including substance containing iron oxides and carbonaceous reducing agent is loaded above carbonaceous material distributed over furnace hearth. Said mix is heated to 1200-1500°C to reduce iron oxides and fuse reduced iron and granulated iron is separated from formed slag. Note here that oxygen partial pressure in atmospheric gas wherein said mix is heated is tom at least, 2.0x10-13 in standard state while linear rate of atmospheric gas in furnace after start of melting is set to, at least, 4.5 cm/s.
EFFECT: low content of phosphorus.
