Hereinafter, specific embodiments of the present invention will be described in detail with reference to the drawings.

1 is a schematic configuration diagram of a spherical titanium powder manufacturing apparatus 1 according to the present invention is shown.

The spherical titanium powder manufacturing apparatus 1 according to the present invention largely includes a main chamber 10 , a spheroidization unit 20 , and a deoxidizer tray 30 .

The main chamber 10 has an inner space formed in an inert gas atmosphere, and is sealed from the outside. The inner space of the main chamber 10 may be formed, for example, in an argon (Ar) atmosphere.

The spheroidizing unit 20 is located at the upper end of the main chamber 10 , and supplies the spherical titanium powder formed at the top of the inner space of the main chamber 10 while forming the spherical titanium powder. That is, the spheroidizing unit 20 directly supplies the formed spherical titanium powder to the inner space of the main chamber 10 without exposing it to the atmosphere. The spherical titanium powder supplied to the upper end of the main chamber 10 falls to the lower end of the inner space of the main chamber 10 by its weight.

The deoxidizer tray 30 is a configuration in which the deoxidizer is charged, and is formed to be movable to the lower end of the inner space of the main chamber 10 and to the outside. In other words, the deoxidizer tray 30 receives the deoxidizer from the outside of the main chamber 10 and then moves to the bottom of the inner space of the main chamber 10 to receive the spherical titanium powder falling from the top of the space of the main chamber 10 . can In addition, deoxidation is performed on the spherical titanium powder in contact with the deoxidizer in the deoxidizer tray 30 .

The deoxidizer tray 30 may be loaded with, for example, calcium as a deoxidizer.

As described above, according to the spherical titanium powder manufacturing apparatus 1 according to the present invention, the spherical titanium powder is directly supplied to the main chamber 10 of an inert gas atmosphere, so that the spherical titanium powder is not exposed to the atmosphere. No oxide layer is formed. In addition, since the deoxidation process can be continuously performed after spheronization of the spherical titanium powder without an oxide layer, the efficiency of the deoxidation process is high, and thus, it is possible to easily manufacture a low-oxygen spherical titanium powder.

As shown in FIG. 1 , the spheroidizing unit 20 includes a melting unit 21 and a gas atomizing unit (not shown), and it is possible to make titanium into a spherical powder through gas atomization.

More specifically, the melting part 21 serves to melt the titanium ingot by heating, and the gas spraying part sprays gas on the molten titanium ingot to granulate the molten titanium. Particulate titanium through gas atomization is formed into spheres.

The gas injection by the gas atomizing part is performed in a direction to move the molten titanium to the upper part of the space of the main chamber 10 so that the spherical titanium powder formed in the spheroidizing part 20 can be supplied to the upper part of the main chamber 10 space. will lose

Titanium is an active metal, and since a problem of reacting with the crucible may occur when a crucible is used when melting, it is preferable that the spheroidizing part 20 is subjected to an Electrode Induction Gas Atomization.

The gas atomizer may inject an inert gas in consideration of the atmosphere of the main chamber 10 .

The spherical titanium powder made by the spheroidizing part 20 may be cooled while falling from the upper end of the main chamber 10 to the lower end.

2 shows a second embodiment of the spheroidizing part 20 . The spheroidizing unit 20 according to the second embodiment includes a powder supply unit 22 and a powder heating unit 23 .

The powder supply unit 22 supplies prismatic titanium powder, and the powder heating unit 23 heats the supplied prismatic titanium powder and melts the powder to make it spherical.

The powder supply unit 22 supplies the titanium powder while dispersing it through the nozzle so that each of the spherical titanium powders made after being melted can maintain a powder state. The powder heating unit 23 may be formed of, for example, a plasma torch, and the powder supply unit 22 may supply titanium powder to the inside of the plasma torch as the powder heating unit 23 .

The spherical titanium powder manufacturing apparatus 1 according to the present invention may further include an atmosphere maintaining unit 40 .

The atmosphere maintaining unit 40 serves to maintain the atmosphere of the inner space in which the process is performed among the spaces in which the deoxidizer tray 30 moves as an inert gas atmosphere. For example, the inert gas atmosphere in the main chamber 10 is prevented from being broken while the deoxidizer tray 30 is moved from the outside of the main chamber 10 to the inside.

The atmosphere maintaining unit 40 may include a load lock chamber 41 . The load lock chamber 41 is formed to selectively communicate with the internal space to which the deoxidizer tray 30 is to move, and the inside thereof may be an atmospheric atmosphere or an inert gas atmosphere.

Specifically, the atmosphere of the internal space in which the deoxidizer tray 30 moves may be maintained by the atmosphere maintaining unit 40 in the following manner. The principle of the atmosphere maintaining unit 40 will be described with an example in which the deoxidizer tray 30 moves from the outside of the main chamber 10 to the inside.

The load lock chamber 41 is opened while the load lock chamber 41 and the main chamber 10 are not communicating, and the deoxidizer tray 30 in which the deoxidizer is loaded is moved into the load lock chamber 41 . Then, while closing the load lock chamber 41, an inert gas is injected into the load lock chamber 41 to create an inert gas atmosphere inside the load lock chamber. Finally, the deoxidizer tray 30 is moved into the main chamber 10 by making the load lock chamber 41 and the main chamber 10 communicate. When the deoxidizer tray 30 is moved into the main chamber 10 , the inert gas atmosphere of the main chamber 10 can be maintained because both the load lock chamber 41 and the main chamber 10 are inert gas atmospheres.

The spherical titanium powder manufacturing apparatus 1 according to the present invention may further include a tray heating unit 60 .

The tray heating unit 60 heats the deoxidizer tray 30 in which the deoxidizer and the spherical titanium powder are charged, so that the deoxidation process of the spherical titanium powder by the deoxidizer proceeds more effectively.

The tray heating unit 60 preferably heats the deoxidizer tray 30 below the vaporization temperature of the deoxidizer. In this case, since it is possible to prevent the deoxidizer from melting and fusion with the spherical titanium powder, recovery of the spherical titanium powder after deoxidation is easy, and contamination of the device by the vaporized deoxidizer can be prevented.

For example, when calcium is used as the deoxidizer, the heating unit may heat the deoxidizer tray 30 to less than 800°C.

As shown in FIG. 1 , the tray heating unit 60 may be located in the main chamber 10 .

In this case, the spherical titanium powder that has fallen into the deoxidizer tray 30 may be directly deoxidized.

According to the conventional spherical titanium powder deoxidation process, as shown in Fig. 3 (a), the process proceeds through the processes of spheroidization, transport / transfer, heat treatment furnace charging, deoxidation, and cooling / transport, After heating, the titanium powder had to be cooled and then heated again for deoxidation, so the entire process took a long time and required a lot of energy. In contrast, in the present invention, as shown in (b) of FIG. 3, the deoxidation process of spherical titanium powder proceeds through the processes of spheronization, mixing of spheroidized powder and deoxidizer, deoxidation, and cooling / discharging, Since the spheronization process, mixing of the spheronized powder and the deoxidizer, and the deoxidation process are continuously performed in the main chamber 10, it is possible to reduce the time and energy required for the entire process.

When the tray heating unit 60 is located in the main chamber 10, in order to effectively heat the deoxidizer tray 30, the tray heating unit 60 is preferably disposed adjacent to the outer surface of the deoxidizer tray 30, It is preferably arranged so as not to obstruct the movement of the deoxidizer tray 30 so as to be adjacent to the bottom surface among the outer surfaces of the deoxidizer tray 30 .

The tray heating unit 60 may be formed of, for example, a coil-type heater.

The tray heating unit 60 may be located outside the main chamber 10 . 4 is an explanatory view of the spherical titanium powder manufacturing apparatus 1 having such a tray heating unit 60 is shown.

When the tray heating unit 60 is located outside the main chamber 10, the spherical titanium powder manufacturing apparatus 1 according to the present invention may further include a deoxidation furnace 70, and the tray heating unit 60 may be formed in the deoxidation furnace 70 .

The deoxidation path 70 is located adjacent to the main chamber 10 , and the inner space may be made of an inert gas atmosphere, similar to the main chamber 10 .

In the spherical titanium powder manufacturing apparatus 1 of this embodiment, the deoxidizer tray 30 in which the deoxidizer and the spherical titanium powder are charged together in the main chamber 10 is moved to the deoxidation furnace 70, and then the deoxidation process is performed. The atmosphere maintaining unit 40 is also applied between the main chamber 10 and the deoxidation furnace 70 , so that when the deoxidizer tray 30 moves from the main chamber 10 to the deoxidation furnace 70 , the main chamber 10 and the deoxidation furnace 70 . It is possible to prevent the inert gas atmosphere of (70) from being destroyed.

When the deoxidizer 70 is located separately from the main chamber 10, after moving the deoxidizer tray 30 from the main chamber 10, a new deoxidizer tray 30 is immediately moved to the main chamber 10 to remove the titanium It is possible to proceed with the spheronization process. That is, the deoxidation process of one cycle and the spherical process of the next cycle are performed at the same time, thereby increasing the efficiency of manufacturing the spherical titanium powder.

Since the spherical titanium powder does not fall into the deoxidizer tray 30 in the deoxidizer 70, the tray heating unit 60 is positioned adjacent to the upper and lower portions of the deoxidizer tray 30 to see the tray heating unit 60 can be heated effectively.

In the case where the tray heating unit 60 is provided on the outside of the main chamber 10, the spherical titanium powder deoxidation process is as shown in FIG. It proceeds through the process of transfer, deoxidation, and cooling/discharging. In the spherical titanium powder deoxidation process in this embodiment, while the deoxidizer tray 30 is moved from the main chamber 10 to the deoxidizer 70, the temperature of the deoxidizer tray 30 drops, but almost immediately the deoxidizer 70 Since the de-phase process is performed, it is possible to reduce the energy and time required for heating the deoxidizer tray 30 in the deoxidation furnace 70 .

When the deoxidation furnace 70 is provided outside the main chamber 10 , the spherical titanium powder manufacturing apparatus 1 according to the present invention may further include a deoxidizer addition unit 80 .

The deoxidizer addition unit 80 may additionally supply a deoxidizer to the deoxidizer tray 30 in the deoxidizer 70 to further increase the efficiency of deoxidation.

The spherical titanium powder manufacturing apparatus 1 according to the present invention may further include a tray vibrating unit 50 .

The tray vibrator 50 is located at the lower end of the main chamber 10, and evenly mixes the spherical titanium powder falling into the deoxidizer tray 30 and the deoxidizer located in the deoxidizer tray 30 to increase the efficiency of deoxidation. .

The spherical titanium powder manufacturing apparatus 1 according to the present invention may further include a cooling chamber 90 .

The cooling chamber 90 serves to cool the spherical titanium powder after the deoxidation process. The cooling chamber 90 is located outside the main chamber 10 and consists of an inert gas atmosphere.

The cooling chamber 90 rapidly cools the spherical titanium powder heated during the deoxidation process, thereby reducing the time of the entire process. In addition, after the deoxidizer tray 30 moves to the cooling chamber 90 , it is possible to perform a deoxidation process on the other deoxidizer tray 30 in the deoxidizer 70 .

When the tray heating unit 60 is located in the main chamber 10 , the atmosphere maintaining unit 40 is applied between the main chamber 10 and the cooling chamber 90 , and the tray heating unit 60 is installed in the main chamber 10 . ) An atmosphere maintaining unit 40 may be applied between the deoxidation furnace 70 and the cooling chamber 90 when located outside. Accordingly, the spherical titanium powder can be efficiently made in a hypoxic state without being exposed to the atmosphere throughout the process using the spherical titanium powder manufacturing apparatus 1 according to the present invention.

Hereinafter, a method for manufacturing a spherical titanium powder according to the present invention will be described. While explaining the spherical titanium powder manufacturing method according to the present invention, detailed description of the matters mentioned in the description of the spherical titanium powder manufacturing apparatus 1 of the present invention may be omitted.

6 is a flowchart of a spherical titanium powder manufacturing method according to the present invention.

In the tray loading step (S10), the deoxidizer tray 30 in which the deoxidizer is loaded is moved to the lower end of the inner space of the main chamber 10 in an inert gas atmosphere. When the deoxidizer tray 30 is moved into the main chamber 10 , the deoxidizer tray 30 can be moved without destroying the inert gas atmosphere of the main chamber 10 by using the atmosphere maintaining unit 40 .

In the spherical titanium powder supply step (S20), the spherical titanium powder is supplied to the upper part of the space of the main chamber 10 while forming. That is, the spherical titanium powder is supplied to the main chamber 10 immediately after the spheroidization of the titanium powder to prevent oxidation of the spherical titanium powder. The spherical titanium powder supplied to the upper part of the space of the main chamber 10 falls into the deoxidizer tray 30 located at the lower part of the space of the main chamber 10 .

In the deoxidation step (S40), the spherical titanium powder dropped into the deoxidizer tray 30 is deoxidized. The spherical titanium powder falling into the deoxidizer tray 30 can be effectively deoxidized because it is in an unoxidized state and comes into contact with the deoxidizer in the deoxidizer tray 30 .

In the deoxidation step (S40), the deoxidizer tray 30 may be heated to effectively deoxidize.

In the spherical titanium powder supply step (S20), it is possible to form a spherical titanium powder through a gas spraying method. That is, after melting the titanium ingot, gas may be sprayed on the molten titanium to make the molten titanium into spherical particles.

The gas injection for the molten titanium is made in the direction of the inner space of the main chamber 10 , so that the spherical granulated titanium may be directly supplied to the main chamber 10 .

In the spherical titanium powder supply step (S20), it is also possible to heat the prismatic titanium powder to make the spherical titanium powder. That is, the prismatic titanium powder can be supplied into the main chamber 10 while being dispersed and heated at the same time to melt each of the prismatic titanium particles to form a spherical shape.

In the spherical titanium powder supply step (S20), the deoxidizer tray 30 may be vibrated.

The vibrating deoxidizer tray 30 may evenly mix the deoxidizer positioned therein with the spherical titanium powder falling from the top of the space of the main chamber 10 to increase the efficiency of deoxidation.

The spherical titanium powder supply step ( S20 ) and the deoxidation step ( S40 ) may be performed almost simultaneously in the main chamber 10 . In this case, since it is possible to proceed to the deoxidation step (S40) without moving the deoxidizer tray 30 after the tray loading step (S10), the time required for the movement of the deoxidizer tray 30 and the deoxidizer tray 30 that is cooled during movement The time and energy required for reheating can be reduced.

Alternatively, the deoxidation step (S40) is made outside the main chamber 10, and as shown in FIG. 7, the tray moving step (S30) is further performed between the spherical titanium powder supply step (S20) and the deoxidation step (S40). can In this case, the spherical titanium powder manufacturing apparatus 1 according to the present invention may further include a deoxidation furnace 70 of an inert gas atmosphere.

In the tray moving step (S30), the deoxidizer tray 30 is moved to the deoxidizer 70 while maintaining the inert gas atmosphere, thereby preventing the spherical titanium powder from being oxidized while the deoxidizer tray 30 is moved. In the tray moving step (S30), the atmosphere maintaining unit 40 may be used to maintain an inert gas atmosphere in the spaces in which the deoxidizer tray 30 moves.

When the method for manufacturing spherical titanium powder according to the present invention further includes the tray moving step (S30), in the deoxidation step (S40), the deoxidation process may be performed while additionally supplying a deoxidizer into the deoxidizer tray 30. Accordingly, it is possible to further increase the deoxidation efficiency of the spherical titanium powder.

In the deoxidation step (S40), the deoxidizer tray 30 may be heated below the vaporization temperature of the deoxidizer.

In this case, while the efficiency of deoxidation can be increased by heating the deoxidizer tray 30 , since the deoxidizer is not vaporized, the deoxidizer is fused with the spherical titanium powder, or the vaporized deoxidizer is the main deoxidation step (S40) in progress Contamination of the inside of the chamber 10 or the inside of the deoxidation furnace 70 can be prevented.

The method for manufacturing spherical titanium powder according to the present invention may further include a cooling step (S50).

The cooling step (S50) is performed after the deoxidation step (S40), and is a step of rapidly cooling the deoxidizer tray 30 heated in the deoxidation step (S40). The cooling step (S50) is performed in an inert gas atmosphere to prevent oxidation of the spherical titanium powder even during cooling.

The scope of the present invention is not limited to the above-described embodiments, but may be implemented in various types of embodiments within the scope of the appended claims. Without departing from the gist of the present invention claimed in the claims, it is considered to be within the scope of the claims of the present invention to various extents that can be modified by any person skilled in the art to which the invention pertains.
