FIELD: metallurgy.
SUBSTANCE: furnace consists of working chamber, of loading devices for charge, of independent sources of heating, of melting cold sole with cold lip and of crystalliser. The latter is made pass-through and transparent for electromagnetic field with frequency 0.1-5 MHz created with an inducer positioned on the crystalliser. The lip is additionally equipped with the inducer and is transparent for electro-magnetic field of 0.1-5 MHz frequency.
EFFECT: design of furnace optimally combining advantages of furnaces with cold sole and induction furnaces which facilitates production of ingots of high quality in one melt.
