FIELD: metallurgy.
SUBSTANCE: according to procedure consumable electrode is vertically pat welded in water cooled crystalliser and simultaneously perforating burnisher is advanced through orifice in bottom. During whole process of re-melting the consumable electrode is rotated around its axis with frequency facilitating distribution of drops of electrode metal along radial trajectory to periphery of slag and liquid metal baths beyond boundaries of sub-electrode zone.
EFFECT: upgraded quality of produced hollow ingots due to elimination of non-metal particles intrusion into metal and avoiding wear of perforating burnisher.
