DEVICE FOR MAGNESIUM-REDUCED PRODUCTION OF SPONGE TITANIUM Russian patent published in 2005 - IPC

FIELD: non-ferrous metallurgy.

SUBSTANCE: device comprises electric furnace that receives the reducing apparatus which has reducing retort with the bottom branch pipe, false bottom, and lid with branch pipe for supplying magnesium, branch pipe for evacuating and supplying titanium tetrachloride and water-cooled flange with the openings for supplying, measuring, and discharging argon from the apparatus, drain device with seat, valving needle, and guiding pipe. The ratio of the inner diameter of the furnace to the diameter of the retort is (1.12-1.16):1 and the ratio of the height of the false bottom to the height of the retort is (0.07-0.08):1. The device is additionally provided with the shell axially aligned with respect to the bottom branch pipe and rigidly connected to the seat of the drain device. The opening for supplying, measuring, and discharging argon are provided with pulse connecting pipes. The diameter of the shell is equal to the diameter of the guiding pipe. In addition, one of the connecting pipes is connected with the line for supplying argon, and the other one to the instrument for measuring pressure.

EFFECT: enhanced reliability.
