| 简介 |
A method and a device for recovering hydrogen pulverized powder of a raw-material alloy for rare-earth magnets capable of lowering a possibility that hydrogen pulverized powder after hydrogen was pulverized remains in a recovery chamber and capable of enhancing magnetic properties by reducing an amount of oxygen of an obtained rare-earth magnet, a processing container 50 is carried into a recovery chamber 40 from a processing chamber through a carry-in port after inert gas was introduced into the recovery chamber 40 by inert gas introducing means 12, the raw-material alloy for rare-earth magnets in the processing container 50 is discharged into the recovery chamber 40 after the pressure in the recovery chamber 40 was reduced by evacuating means 33 and thereafter, inert gas is introduced into the recovery chamber 40 by inert gas introducing means 12, and the raw-material alloy for rare-earth magnets is recovered into the recovery container 50 from an discharge port 40a after a pressure in the recovery chamber 40 was set to a predetermined pressure by inert gas. |
