DIRECT CURRENT SMELTING FURNACE Russian patent published in 1995 - IPC

FIELD: electric engineering. SUBSTANCE: device has two spaced expendable electrodes which are displaced towards direction, where power supply is placed, from perpendicular to middle plane of smelting tank. In addition device has at least four stationary bottom electrodes which are positioned on both sides from front plane in vertex of quadrangle (polygon), which is in symmetry about middle plane and is positioned between vertical projections of expendable electrodes so that supplying conductors of electrodes which are positioned on power supply side go directly to power supply while all supplying conductors of electrodes which are positioned on another side have first branch which bands around vertical projection of corresponding expendable electrode and second branch which goes to power supply in parallel to conductors which are connected to expendable electrodes. EFFECT: increased functional capabilities. 5 cl, 4 dwg
