| titleOfInvention | Device for preparing titanium rod, titanium alloy and titanium alloy device |
| abstract | The invention discloses a device for preparing a titanium rod, the titanium rod, a titanium alloy and a titanium alloy device. Relates to the technical field of metal smelting and purification. According to the device and the method, titanium oxide or rutile is put into a molten pool for smelting titanium at high temperature by using an argon-hydrogen plasma arc, the titanium oxide or rutile is dissolved in a pure titanium melt at high temperature, then nonmetallic elements such as oxygen are removed by using hydrogen, along with the process of putting reduction smelting, the melt in the molten pool flows into an induction water-cooled copper crucible for directional solidification, and then the directional solidification is carried out again by combining the induction water-cooled copper crucible after zone smelting. Impurity elements are removed by repeatedly separating and purifying through zone melting and directional solidification in an induction water-cooled copper crucible, the device is purified for many times, and finally the purity of the prepared titanium rod is higher through vacuum dehydrogenation of the titanium rod. |
