INSTALLATION FOR MAGNESIUM-THERMAL PRODUCTION OF SPONGE TITANIUM Russian patent published in 2009 - IPC C22B34/12 

FIELD: metallurgy.

SUBSTANCE: installation for magnesium-thermal production of sponge titanium consists of electric pit-type heating furnace with apparatus of reduction in form of retort with cover, false bottom and drainage facility. The electric pit-type heating furnace is made with two rows of channels for supply cooling air, with channels for hot air exhaust and with an opening in a hearth. The upper row of channels for supply of cooling air is arranged at a distance from the top of the electric furnace constituting 0.10-0.12 of its height. The second row of channels for supply of cooling air is arranged at a distance from the top of the electric furnace constituting 0.25-0.27 of its height. Channels for hot air exhaust are arranged at a distance from the top of the electric furnace constituting 0.35-0.45 of its height. Also ratio between the retort of the apparatus of reduction and height of electric furnace is 0.85-0.95.

EFFECT: increased efficiency of installation.
