FIELD: metallurgy.
SUBSTANCE: invention relates to ferrous metallurgy, namely, to devices of mine arc steel-smelting furnaces. Furnace comprises a housing formed by a metal shell with water-cooled wall panels and a lined hearth, a roof and roof electrodes, a loading conveyor for loading the charge, a shaft for heating the charge with exhaust gases installed on the body and a feed conveyor installed in the upper part of the shaft, wherein said loading conveyor is installed in said shaft and is made in form of horizontally installed in tiers links with controlled speed of charge movement. In the loading conveyor links are installed in 4–5 tiers.
EFFECT: invention allows reducing specific power consumption by 40–60 kW-h/t, melting time and increasing furnace capacity.
