Embodiment Construction
[0021] The present invention will be further described below in conjunction with accompanying drawing by embodiment:
[0022] preferred embodiment
[0023] Such as Figure 1-Figure 3 As shown, a vacuum furnace device for dehydrogenation of titanium hydride powder according to the present invention comprises a furnace wall with a hollow interior and an open upper end, a heating device is arranged on the inner wall of the furnace wall, and the furnace tank tube is put in from the top of the furnace wall. There is a lifting ring on the furnace cover at the top of the tank tube. The argon-filled tube passes through the furnace cover and communicates with the inside of the furnace tube. The furnace tube is connected to the external vacuum system. The material tray is installed in the furnace tube through the support shaft. on the tray.
[0024] In the above scheme, there are multiple charging trays, which are fixed on the support shaft at intervals up and down, and the height...

The invention discloses a vacuum furnace device for dehydrogenation of a titanium hydride powder and a dehydrogenation method thereof, which relate to a titanium powder preparation device and a preparation method thereof, aim at solving the problem of the prior art that oxygen content is too high in the dehydrogenation process of the titanium hydride powder, and can greatly reduce dehydrogenation time. The vacuum furnace device comprises a furnace wall; the inner wall of the furnace wall is provided with a heating device; a furnace tank tube is put into the furnace from the upper end of the furnace wall; a lifting ring is arranged on a furnace cap at the top end of the furnace tank tube; an argon charging tube penetrates through the furnace cap and is communicated with the interior of the furnace tank tube; the furnace tank tube is connected with an external vacuuming system; a material tray is arranged in the furnace tank tube through a support shaft; and a titanium powder is arranged in the material tray. With the vacuum furnace device disclosed by the invention, in a vacuum condition, when temperature and pressure are adjusted, the titanium hydride powder can be subjected to dehydrogenation reaction; by continuously adjusting the temperature, keeping the pressure constant, and quickly separating the furnace wall from the furnace tank tube, the titanium hydride powder can be quickly cooled, so that time is saved, production cycle is reduced, and a low oxygen content of the titanium powder is effectively controlled; and the vacuum furnace device can be applied to the dehydrogenation treatment of the titanium hydride powder.
Description
technical field [0001] The invention relates to a device for preparing titanium powder and a preparation method thereof, in particular to a vacuum furnace for preparing titanium powder with low oxygen content and a method for dehydrogenating titanium hydride powder using the vacuum furnace. technical background [0002] At present, powder metallurgy of titanium and titanium alloys (hot isostatic pressing, cold isostatic pressing, metal injection molding, powder injection molding and powder coating) is recognized at home and abroad as the main way to greatly reduce the cost of titanium processing. However, titanium sponge cannot be used directly, so the titanium powder made from titanium sponge is further processed. After the hydrogenation treatment of titanium sponge, titanium hydride powder with different particle sizes will be obtained after crushing, and titanium hydride powder will be dehydrogenated to obtain titanium powder. In the dehydrogenation process of titanium h...
