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 Deltatau=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. ^ 2 dwg |
