Embodiment Construction

[0039] Hereinafter, the manufacturing method and manufacturing apparatus of this invention are demonstrated concretely with reference to drawings.

[0040] figure 1 It is a figure which shows the schematic structure example of the manufacturing apparatus of Ti of this invention. Such as figure 1 shown, the device has: maintain a CaCl-containing 2 And the molten salt with Ca dissolved is used to make the TiCl4 supplied to the molten salt react with the Ca to generate the Ti particle reduction tank 1; it is used to separate the Ti generated in the molten salt from the molten salt Particle separation mechanism; keep the molten salt separated from the Ti particles, have an anode 2 and a cathode 3, and use the main electrolytic tank 5 for electrolysis of the molten salt to generate Ca on the cathode side; provide a Ca supply source, and introduce The molten salt in the main electrolytic tank 5 is used in the adjustment tank 6 for feeding the molten salt into the reduction tank 1...

Abstract

A process for producing Ti, comprising the reduction step of providing a molten salt containing CaCl2 and having Ca dissolved therein and reacting TiCl4 with the Ca to thereby form Ti particles, the separation step of separating the Ti particles formed in the molten salt from the molten salt and the electrolysis step of electrolyzing the molten salt so as to increase the concentration of Ca, wherein the molten salt having the concentration of Ca increased in the electrolysis step is introduced in a regulation vessel to thereby render the Ca concentration of the molten salt constant and thereafter is used in the reduction of TiCl4 in the reduction step. In this process, not only can any fluctuation of Ca concentration of molten salt charged in a reduction vessel be suppressed but also a high concentration thereof can be maintained. Further, continuous processing of a large volume of molten salt becomes feasible. Therefore, the reduction reaction of TiCl4 can be efficiently performed, and as a process for realization of Ti production on an industrial scale, the process can be effectively utilized in the production of Ti by Ca reduction.

Description

technical field [0001] The present invention relates to the treatment of TiCl by reduction of Ca 4 A production method of Ti for producing metal Ti and a production apparatus used in the production method. Background technique [0002] Reduction of TiCl by Mg in an industrial process for metallic Ti 4 The reduction method (kroll method) is a general method. In this reduction method, metal Ti is produced through a reduction step-vacuum separation step. In the reduction process, the liquid TiCl supplied from above in the reaction vessel 4 Molten Mg is reduced to generate particulate metal Ti, which is gradually precipitated downward to obtain spongy metal Ti. In the vacuum separation process, unreacted Mg and by-product MgCl are removed from the spongy metal Ti in the reaction vessel 2 . [0003] In the production of metal Ti by the reduction method, a high-purity product can be produced. However, because it is a batch, the manufacturing cost increases, and the product ...
