Problems solved by technology

However, there is such a problem that any method basically needs to adopt a high level of vacuum state to separate the by-product MgCl 2 or unreacted magnesium, which is difficult to handle in large quantities

Embodiment

[0073] use figure 1 The metal titanium manufacturing device produced metal titanium. In the magnesium heating unit 1 , solid magnesium is inserted into the crucible 2 . Then, the crucible 2 was inductively heated by the heater 3 to a temperature capable of evaporating magnesium, thereby obtaining gaseous magnesium. In the titanium tetrachloride heating unit 20 , liquid titanium tetrachloride is supplied from the supply unit 26 toward the plasma flame generated from the plasma torch 22 . Then, titanium tetrachloride was turned into a gaseous state by plasma heating. This gaseous titanium tetrachloride has an extremely high temperature exceeding 1600°C.

[0074] Next, the gaseous titanium tetrachloride was passed through the second flow path 24 together with argon gas as a carrier gas, and flowed into the inlet flow path 32 of the Venturi part 30 . In addition, the aforementioned gaseous magnesium passes through the first flow path 5 induction-heated by the heater 6 and is s...

Abstract

A device for producing titanium metal comprises (a) a first heating unit that heats and gasifies magnesium and a first channel that feeds the gaseous magnesium, (b) a second heating unit that heats and gasifies titanium tetrachloride so as to have a temperature of at least 1600 C and a second channel that feeds the gaseous titanium tetrachloride, (c) a venturi section at which the second channel communicates with an entrance channel, the first channel merges into a throat and as a result the magnesium and the titanium tetrachloride combine in the throat and a mixed gas is formed in the exit channel, and in which the temperature of the throat and the exit channel is regulated to be at least 1600 C, (d) a titanium metal deposition unit that communicates with the exit channel and has a substrate for deposition with a temperature in the range of 715-1500 C, and (e); a mixed gas discharge channel that communicates with the titanium metal deposition unit.

Description

technical field [0001] The present invention broadly relates to methods and apparatus for producing titanium metal. Specifically, the present invention relates to a method for producing metallic titanium and an apparatus for producing metallic titanium by precipitating and growing metallic titanium from a mixed gas of titanium tetrachloride and magnesium. Background technique [0002] Titanium is widely used in various fields such as aircraft, medical treatment, and automobiles due to its light weight, high relative strength, and excellent corrosion resistance, and its usage is increasing. The storage of titanium in the earth's crust accounts for the fourth largest storage of practical metal elements after aluminum, iron and magnesium, and is an element with abundant resources. Although titanium resources are so abundant, the price of titanium is more than one digit higher than that of steel materials, and it is facing the current situation of insufficient supply.
