Abstract: Method of producing FeSiAI alloys wherein a carbonaceous rock with an ash content >50% to <65%, is being mixed with quartzite, iron-bearing material, and wood chips, if required, high volatile coal, in a preset ratio of the charge components and the homogenized charge material is being loaded into a melting furnace for melting of FeSiAI alloy, the charged carbonaceous rock can contain i.a. the following chemical composition in the mineral part (ash): Fe2O3 1.5-4.5% SiO2 55-65% Al2O3 25-35%, especially 32-34% CaO 0.3-3% MgO 0.3-2% TiO2 up to 1.5 S>0-0.4%, especially 0.01-0.06% P 0.01-0.

Abstract: Ferrous metallurgy for producing an alloy for reducing, doping and modifying steel is disclosed. The quality of the steel treated with the inventive alloy is improved owing to the deep reduction and modification of non-metallic impurities and the simultaneous microalloying of steel with barium, titanium and vanadium. Barium, titanium and vanadium are added into the inventive alloy, which contains aluminum, silicon, calcium, carbon and iron, with the following component ratio, in mass %: 45.0-63.0 silicon, 10.0-25.0 aluminum, 1.0-10.0 calcium, 1.0-10.0 barium, 0.3-5.0 vanadium, 1.0-10.0 titanium, 0.1-1.0 carbon, the rest being iron.
