FIELD: metallurgy.
SUBSTANCE: invention relates to special electrometallurgy and can be used at manufacturing of hollow ingots by method electroslag remelting, including complex-alloyed, not containing titanium steels. Method includes remelting of consumed electrode on basic flux, containing, wt %: calcium fluoride 37-45, aluminium oxide 13-17, lime 24-30, silicon oxide 11-15, magnesium oxide 2-6, and accessory, containing, wt %: calcium fluoride 65-70, aluminium oxide 12-17, silicon oxide 8-10, magnesium oxide 8-10.
EFFECT: provided content of accessory flux provides receiving of ingots of height more than 3000 mm with uniform properties by height.
