METHOD OF STEEL PRODUCTION IN ELECTRIC ARC FURNACE Russian patent published in 2017 - IPC C21C5/52 F27B3/08 

FIELD: metallurgy.

SUBSTANCE: invention relates to metallurgy and can be used in production of steel in an electric arc furnace. Method involves loading into the furnace working space a solid metal charge and solid carbon-containing materials, the charge melting by means of electric arcs and carbonization of the metal with the solid carbon-containing materials during the melting, tapping the metal and slag from the furnace. For additional carbonization of the metal during melting the furnace working space is fed with iron oxides and a carbonaceous material in an amount sufficient for obtaining a high-carbon carbonator in the form of a liquid phase of the reduced in the iron arcs with carbon combustion zone in free and dissolved forms. Herewith the flow rate of iron oxides and the carbonaceous material enabling to obtain the high-carbon carbonator for the melting is not less than 3 % from the metal charge weight.

EFFECT: invention increases output of liquid metal due to regulation of carbon content during melting, provides higher degree of metal carbonization since the very beginning of melting and reduction of iron loss into slag and smoke.
