FIELD: metallurgy.
SUBSTANCE: method includes portion supply of alloying difficulty feasible materials to a regular space at the instant the current in the electrode is turned off each Δτ=m/v, where m is the mass of liquid metallic bath in the steady-state period of melting, in kg, and v is the rate of ingot melting, in kg/s. Allowing difficulty feasible materials are supplied to the center of the slag bath through the opening in the electrode.
EFFECT: improved quality of the multiplayer ingots.
