METHOD FOR STOPPING UNCONTROLLED DRAINING OF MELT FROM REACTOR FOR MAGNESIUM REDUCTION OF TITANIUM TETRACHLORIDE Russian patent published in 2008 - IPC C22B34/12 C22B5/04 

FIELD: magnesium-reduced production of spongy titanium, in particular, process for stopping uncontrolled draining of melt from reactor designed for magnesium reduction of titanium tetrachloride, may be used in non-ferrous metallurgy.

SUBSTANCE: method involves stopping the process of feeding titanium tetrachloride and argon into reactor when drainage apparatus is depressurized; in case of depressurizing of drainage apparatus, creating and maintaining vacuum in reactor according to amount of melted magnesium, with vacuum extent being calculated from equation: V=(0.8-0.9)x(1-C)xH_rxd_mg, where V is vacuum in reactor, kgf/cm²; (0.8-0.9) is maximum level of magnesium in reactor, part; (1-C) is coefficient taking into account unused magnesium in the course of reduction process, part; H_r is height of reactor, cm; C is coefficient of utilization of magnesium, part; d_mg is density of magnesium at temperature of 800 C, kgf/cm².

EFFECT: reduced losses of magnesium and spongy titanium upon depressurizing of drainage apparatus of reactor due to burning and pouring out of magnesium.
