CHARGE FOR PRODUCING IRON ORE AGGLOMERATE Russian patent published in 2021 - IPC C22B1/14 

FIELD: metallurgy.

SUBSTANCE: invention relates to the field of ferrous metallurgy, in particular, to production of iron ore agglomerate. The mixture comprises iron-containing materials, vanadium-containing materials, a flux, solid fuel and a high-titanium concentrate including, % wt.: Fe 56.0 to 61.0; V₂O₅ 1.30 to 2.0; TiO₂ 4.0 to 7.0, at the following ratio of components, % wt.: flux 10.0 to 20.0; high-titanium concentrate 0.5 to 25.0; solid fuel 3.0 to 10.0; vanadium-containing materials 2.0 to 20.0; iron-containing materials the rest. The charge therein comprises sinter screenings, metallurgical dust and sludge, waste slag processing products in the form of metal products as iron-containing materials. As vanadium-containing materials, the charge comprises prepared converter slags: monoprocess slag and/or vanadium-containing converter slag, and/or duplex process slag in the form of steel converter slag and/or a mixture based thereon. As a solid fuel, the charge comprises coke. As a flux, the charge comprises limestone.

EFFECT: invention provides a 1.09% abs. increase in the iron content in the agglomerate, a 0.185% abs. increase in the content of V₂O₅ in the agglomerate, and a 27% increase in the production of iron flux.
