Due to the presence of surface oxide titanium block after grade 5 titanium cutting, easily mixed with coolant and metal-cutting equipment and other issues, recycling more difficult. Therefore, the development of a low-grade titanium chloride reacted with the iron scrap, recycling processes titanium tetrachloride gas.
Titanium tetrachloride is reduced in the next process, thereby obtaining titanium. Ferric chloride is difficult to handle the waste generated during the smelting of titanium. Rational use of chlorinating agents can reduce costs, improve resource efficiency. All along, titanium scrap and iron chloride will react after the titanium surface covered with a layer of iron, titanium and ferric chloride lead to termination of the reaction. This time, to add magnesium titanium alloy bar chloride, samarium molten salt as a medium to make it happen with the titanium chlorination. Because of ferric chloride and titanium without the direct reaction, the reaction stops phenomenon and therefore does not appear. In the experiment, a titanium rod after 1100 ℃ treatment, one hour can take place completely vaporized.
