METHOD OF SUPPLY OF PRODUCTION LINE WITH DIRECT CURRENT AND DEVICE FOR ITS REALIZATION Russian patent published in 1997 - IPC

FIELD: production of nonferrous metals, in particular, production of magnesium. SUBSTANCE: part of current applied to one of the electrolyzers of the production line is fed to the apparatus for preparation of material to electrolysis; the strength of the transmitted current is adjusted by varying the electrical resistance of the apparatus for preparation of raw material and maintained within 10 to 40% of the value of continuous current. Current distribution in the "electrolyzer-apparatus for preparation of raw material: system is controlled by connection or disconnection of the electrodes on the apparatus for preparation of raw material. The apparatus for preparation of raw material and one of the electrolyzers of the production line are combined by a common bus arrangement furnished with an electrode polarity change-over switch. EFFECT: improved use of current, enhanced stability and efficiency of operation of the leading unit and production line, reduced cost, enhanced quality of raw material and reliability of operation. 4 cl, 2 dwg
