FIELD: metallurgy, aluminothermic process, in particular manufacturing of refractory metal-based addition alloys for doping of titanium-based alloys. ^ SUBSTANCE: claimed batch contains refractory metal high oxides, aluminum powder, calcium oxide and fluoride-based fluxing agents, refractory metal low oxides and ballast additives if form of addition alloy and/or titanium powder or sponge waste returns. Vanadium trioxide and/or molybdenum dioxide are used as refractory metal low oxides. According to this invention, it is made possible to increase recovery degree of valuable components by 1.5-2.0 % and decrease refractory metal oxide content in dross. Utilization of addition alloy crumb returns makes it possible to increase the ingot-to-product yield by 2-4 %. ^ EFFECT: addition alloys with improved quality. ^ 2 cl, 4 ex, 3 tbl |
