熱されている。To remove the Ar gas, a batch type vacuum degassing device is used as disclosed in Japanese Utility Model Publication No. 58-42414. Inside the vacuum degassing chamber of the vacuum degassing device,
A spiral gutter is provided, and a certain amount of metal powder introduced into the degassing chamber is constantly moved through the planting soil by imaging, during which time Ar gas is sufficiently removed. When the Ar gas is removed, the metal powder is discharged out of the vacuum degassing chamber by the vibration, and is charged into a metal powder processing capsule provided in communication with the degassing chamber. The capsule is
One or more are prepared to match the powder throughput of the vacuum degassing device. The effective Ar gas removal conditions are 3.
The vacuum atmosphere is 00°C and I x 10-5 torr, and the vacuum degassing chamber is set to such processing conditions, and the temperature of the powder when it is filled into capsules is controlled by the vacuum degassing It is heated to 300°C by a device.

した粉末は酸化してしまい、使用不可能になる。(Problem to be solved by the invention) However, when the frequency of the vibration for metal powder transfer is constant, the amount of powder transferred per unit time is large for the filling amount, and decreases as time passes, so When filling several capacity capsules, it is very difficult to fill each capsule with a constant amount of powder (the optimal filling amount for the capsule). If there is too much powder, the capsule cannot be sealed and the powder must be taken out into the atmosphere, where it will oxidize and become unusable.

とは極めて困難である。As a method of filling a predetermined amount of the degassed metal powder, it is possible to fill the powder through a metering device or a weighing device, but it is extremely difficult to install these devices in a high vacuum.

A certain amount of powder is put into a vacuum degassing chamber, and the metal powder is degassed while the soil formed in the vacuum degassing chamber is transferred by vibration, and then the metal powder is transferred outside the vacuum degassing chamber. In the method of discharging the metal powder by vibration and charging it into a metal powder processing capsule connected to the degassing chamber, the frequency of the vibration for transporting the metal powder is increased or decreased depending on the capacity of the capsule. The point is to fill the capsule.

One capsule is completed in a processing time of XA minutes + 30 Hz x 5 minutes, and the next capsule can be similarly filled with powder optimally. If the frequency is constant as before, for example 60H
With Z, the transfer rate was 18 kg/min (when the input rate was 100 ktr), which was a large amount to transfer per unit time, and it was extremely difficult to control the predetermined amount.
