FIELD: metallurgy.
SUBSTANCE: loading of metal charge and its subsequent smelting with an electron beam or plasma is performed to an upper crystalliser provided with a vertical slot, into which prior to loading of metal charge there installed is a plate from molten metal cleaned from impurities, which covers the above slot; surfacing is performed in an upper crystalliser of a molten metal bath with the depth of not more than 50 mm, without penetration of the above plate; a slot is penetrated with an electron beam or plasma in the above plate to the depth of that is less than depth of the surfaced molten metal bath by 20-30% and refined portion of molten metal is drained to the lower crystalliser for formation of an ingot. In the upper crystalliser there made is a vertical slot covered with a plate from molten metal cleaned from impurities with formation of a projection to retain heavy impurities during the melting process, and the above crystallisers are installed on a tray.
EFFECT: invention allows improving use efficiency and enlarging technical capabilities owing to reducing power consumption, shortening of a production cycle, increasing metal weight at surfacing and reducing the equipment dimensions.
