発明の名称 (英語) APPARATUS AND METHOD FOR PRODUCING METAL TITANIUM
発明の概要(英語) An apparatus for producing metal titanium is provided with a reduction device (1, 2, 3, 4, 5) for carrying out a reduction treatment of titanium tetrachloride (X2) in the presence of bismuth (X1) and magnesium (X3) to produce a liquid alloy (X4) composed of titanium and the above-mentioned bismuth, a segregation device (6) for carrying out a segregation treatment of the liquid alloy to produce deposits, and a distillation device (8) for carrying out a distillation treatment of the deposits to produce metal titanium, wherein, in the distillation device, the atmosphere is set in such a manner that the bismuth adhered to the deposits can be vaporized preferentially and is subsequently set in such a manner that the bismuth that forms the deposits can be vaporized.
従来技術、競合技術の概要(英語) BACKGROUND ART
In the following Patent Document 1, a titanium alloy can be obtained efficiently, the titanium alloy metal purification of the titanium produced continuously at a low cost (smelting) can be disclosed a method of manufacturing titanium. This manufacturing method, a mixture of bismuth and magnesium titanium tetrachloride (TiCl4) was added to the liquid alloy of bismuth and titanium (reduction step) and the step 1, the liquid alloy by performing distillation treatment step of removing the components other than the titanium 2 and comprises as the basic steps (distillation step), step 1 and step 2 and the liquid alloy segregation between the liquid portion, a solid-liquid coexisting solid and liquid in the presence of a separating portion and the auxiliary step as (segregation step).
