METHOD OF PRODUCING TITANIUM-IRON ALLOY AND DEVICE FOR IMPLEMENTATION THEREOF Russian patent published in 2020 - IPC C25C3/36 C25C7/00 

FIELD: metallurgy.

SUBSTANCE: group of inventions relates to metallurgy, particularly to electrolytic methods of producing inorganic compounds based on rare and dispersed metals, and an electrolysis cell for carrying out said method. Method of producing titanium-iron alloy containing 63–78 wt. % of titanium includes preparation of salt mixture consisting of cryolite and aluminum fluoride with cryolite ratio equal to 2.7–3.0, drying of said mixture, heating to liquid state and transfusion as electrolyte into electrolytic cell. Then melted at temperature of 1185–1200 °C. Titanium-iron alloy containing 63–65 wt. % of titanium is fed via electrolyte into molybdenum receiver of cathode. Then, through gap between anode and side wall of electrolyser to electrolyte, having temperature of 1100–1150 °C, powdered titanium oxide is loaded with excess and includes a combined source of direct and alternating current or DC and AC sources with provision of electrolyte temperature in range of 1185–1200 °C and content of titanium oxide in electrolyte 1–9 wt. %. Iron chips are introduced and finished product is unloaded in form of titanium-iron alloy. Electrolysis cell comprises graphite anode and cathode from refractory metal, at that it contains bead refractory non-electroconductive lining, corundum lining, graphite bottom, unloading pocket for unloading of finished product in form of titanium-iron alloy, having temperature of 1135–1185 °C. Said unloading channel is connected to molten metal by horizontal channel. In the upper part of the said lining between the graphite anode and the side wall of the electrolytic cell there is an armhole in the refractory lid of the said unloading pocket for supply of titanium oxide into the working space of the bath at temperature of 1100–1150 °C.

EFFECT: reduced power consumption and increased stability of electrolysis process when producing titanium-iron alloy.
