PROCEDURE FOR BLAST MELTING TITANIUM-MAGNETITE RAW MATERIAL Russian patent published in 2010 - IPC C22B5/02 

FIELD: metallurgy.

SUBSTANCE: procedure consists in charging and melting raw material, coke, fluxes and manganese containing additives, in blasting hydrocarbon substitutes of coke into blast-furnace hearth and in tapping iron an titanium slag. Manganese containing additive is introduced at amount ensuring contents of manganese not less, than 1 % in iron and ratio of manganese to vanadium 1.0-1.3; also contents of carbon in iron is maintained within ranges 4.5-5.2 % by blasting hydrocarbon gas, and ratio of calcium oxide to titanium dioxide in slag within ranges 0.3-0.7 is maintained by introduction of calcium carbonate.

EFFECT: increased extraction of chromophore into iron, reduced losses of iron with slag, elimination of forming titanium oxy carbonitrides, production of commodity titanium slag suitable for production of pigment.
