摘要

FIELD: metallurgy.;SUBSTANCE: invention relates to metallurgy of ferrotitanium production, containing 28-40 wt % of titanium, which is in demand in industry for production of welding electrodes, for alloying of structural, stainless, fireproof steels. To produce ferrotitanium by double-stage aluminothermal method, a charge is developed with the following composition, wt %: ilmenite concentrate with content of TiO₂ 52-54 wt % 26.6-27.8, secondary aluminium 21.0-27.0, lime with carbon content of not more than 0.3 wt % 4.5-4.9, iron scale 13.2-14.4, ferrosilicon 75% 0.3-0.9, steel scrap 0.5-3.4, ground titanium-containing slag 26.6-29.0, at the same time the titanium-containing slag as a component of the titanium-containing charge is produced in an electric furnace by melting of the charge containing, wt %: ilmenite concentrate with content of TiO₂ 63-65 wt % 75.5-79.2, secondary aluminium 4.9-5.8, lime with carbon content of not more than 0.6 wt % 12.0-13.2, iron scale 2.6-3.8, ferrosilicon 75% 2.6-2.8, after soaking of the melt they drain metal and titanium-containing slag, which is separated, cooled and ground.;EFFECT: invention makes it possible to use new titanium-containing charge compositions without rutile concentrate.;3 cl, 3 tbl
