FIELD: metallurgy.
SUBSTANCE: smelting furnace consists of independent sources of heat, of melting crucible with back wall, of refining crucibles, of crystalliser and of overflow baffles successively arranged on frame of cold sole. Cavities formed in the gap between successively installed elements of the furnace are filled with neutral flux on base of calcium fluoride, while upper edges of the cavities are made as faces at angle 30÷60°.
EFFECT: avoiding metal leaks into gaps between elements of furnace and increasing resistance of sole due to improved conditions of copper crucibles cooling.
