APPARATUS FOR MAGNESIUM-THERMAL PRODUCTION OF TITANIUM SPONGE Russian patent published in 2007 - IPC C22B34/12 

FIELD: non-ferrous metallurgy, namely apparatuses for producing titanium sponge at reducing its tetrachloride by means of magnesium.

SUBSTANCE: apparatus includes reduction unit having retort with bottom branch pipe to which flange of draining device is welded, false bottom, lid with branch pipe for pouring magnesium, unions for evacuating apparatus, measuring pressure and reducing argon pressure. On lid there is one central branch pipe for pouring magnesium and supplying titanium tetrachloride into which cone is welded. Titanium tetrachloride is fed along union passing through limiting member and welded into bushing fluid-tightly joined with said branch pipe. Rings of stand of false bottom are welded to elliptical bottom of retort by means of intermittent welded seam. Grid and stop of false bottom are fastened by means of plates rigidly secured to wall of retort. Thickness of lining of furnace hearth exceeds by 10 - 30% thickness of lining of cylindrical portion of furnace. Opening of furnace hearth is protected by means of shield. Shield is also mounted inside furnace over opening of furnace hearth; relation of shield outer diameter to opening diameter is in range 1.1 - 1.5. Shield having two dampers may be mounted outside furnace in casing of furnace hearth.

EFFECT: enhanced efficiency of apparatus.
