Embodiment Construction

[0039] Next, the method and apparatus for producing Ti reduced by Ca according to the present invention will be described with reference to the drawings.

[0040] FIG. 1 is a diagram showing a configuration example of an apparatus capable of implementing the Ti production method of the present invention (Ti production apparatus of the present invention). As shown in the figure, this device has: TiCl used to make the TiCl supplied in the molten salt 3a 4 Reaction tank 1 that reacts with the above-mentioned Ca to generate Ti; holds CaCl 2 The molten salt 3b has an anode 4 and a cathode (in this example, the continuum 5 constitutes the cathode), electrolysis is performed in the molten salt 3b, and an electrolytic cell 2 that generates Ca on the cathode side; the continuum 5 is partly immersed in the reaction The tank 1 and the molten salts 3a, 3b in the electrolytic tank 2 are configured to be movable, and the above-mentioned generated Ca is separated and attached to the dipped ...

Abstract

A process for producing Ti through Ca reduction, comprising providing an apparatus including a reaction vessel for retaining a molten salt containing CaCl2 and having Ca dissolved therein, an electrolytic vessel for retaining a molten salt containing CaCl2 and continuous means capable of moving while having parts thereof dipped in the molten salts of the reaction vessel and electrolytic vessel; conducting electrolysis of the molten salt of the electrolytic vessel to thereby form Ca on the negative electrode side, the formed Ca deposited on and attached to the continuous means; transporting the Ca to the reaction vessel; and feeding TiCl4 into the reaction vessel to thereby form Ti. This process is economically advantageous as the feeding rate of TiCl4 as a raw material can be increased, as continuous production can be effected, and as Ca consumed by reduction reaction of TiCl4 can be replenished by electrolysis of CaCl2. Thus, this process can be effectively utilized as means for efficient economically advantageous production of high-purity metallic Ti and can find wide applications.

Description

technical field [0001] The present invention relates to the reduction treatment of titanium tetrachloride (TiCl 4 ) to manufacture metal Ti using a Ca-reduced Ti manufacturing method and manufacturing apparatus. Background technique [0002] As an industrial production method of titanium metal, titanium oxide (TiO 2 ) TiCl obtained by chlorination 4 Kroll titanium compound reduction method (Kroll process). In this Kroll titanium compound reduction method, metal Ti is produced through a reduction step and a vacuum separation step, wherein the reduction step is the reduction of TiCl by Mg in a reaction vessel. 4 , the vacuum separation process is to remove unreacted Mg and by-product magnesium chloride (MgCl 2 ). [0003] In the reduction process, molten Mg is filled in the reaction vessel, and TiCl is supplied to the liquid surface from above. 4 liquid. Thus, near the liquid surface of molten Mg, TiCl 4 It is reduced by Mg to generate particulate metal Ti, and at the ...
