METHOD OF MAKING FOIL FROM PURE FERROMAGNETIC METAL AND DEVICE TO THIS END (VERSIONS) Russian patent published in 2012 - IPC C25D1/04 C23C16/08 C23C22/05 C23C16/16 

FIELD: metallurgy.

SUBSTANCE: invention relates to thermochemistry and electrochemistry, particularly, to improvement of electrolytic and carbonyl deposition of continuous-strip foil from iron group, and to devices to this end. Then, refining with decomposition of ferromagnetic material sublimated halide or evaporated carbonyl, or soluble ferromagnetic material compound with deposition either on titanium drum, or titanium drum cathode, are performed. Simultaneously with above refining, refining is performed using permanent magnetic field by arranging magnetic system inside titanium drum comprising either permanent magnets, ferromagnetic tubes and ferromagnetic discs connected in series in magnetic circuit, or ferromagnetic tube and ferromagnetic discs connected in series in magnetic circuit. Ferromagnetic tube is surrounded by permanent magnetic field excitation windings with high-temperature insulation. Note here that said permanent magnetic field is closed on titanium oxide surface made on titanium drum or titanium drum cathode.

EFFECT: high-efficiency production of foil strip of higher operating properties.
