FIELD: metallurgy; semi-continuous molding of consumable electrodes from high-reaction metals and alloys, for example, titanium alloys; making large-sized ingots from alloys.
SUBSTANCE: last portion of charge is molded simultaneously with adapter whose end surface is joined with electrode and is provided with taper projections at inclination of 1-10°. According to this method furnace time is reduced by 20% due to avoidance of furnace evacuation procedures and welding of electrode to adapter.
EFFECT: increased productivity of vacuum electric-arc furnaces.
