Abstract

The present invention relates to a metal spherical powder impurity removal device and impurity removal method. The device comprises a first collection container, a second collection container, a funnel and a separation plate, wherein the second collection container is arranged inside the first collection container, and the second collection container is arranged inside the first collection container. The end face of the collection container is lower than the end face of the first collection container, the separation plate is arranged inside the second collection container, and the end face of the second collection container is inclined at an angle, and does not contact the second collection container, and the funnel is arranged in the two collection containers. Above, and keep a distance between the outlet end of the funnel and the separation plate, the funnel is filled with metal spherical powder to be removed, when the metal spherical powder to be removed falls to the separation plate, the metal spherical powder enters the first collection container, and the impurities enter the second Two collection containers, the present invention realizes the removal of impurities from the metal spherical powder, without the need for power supply, transmission and other power devices, low price, simple structure, no size, shape and position accuracy requirements for processing and assembly, and can achieve high-efficiency and low-cost removal of metal spherical powder. miscellaneous.

Description

technical field [0001] The invention relates to a metal spherical powder impurity removal device and an impurity removal method, belonging to the technical field of high-performance powder metallurgy near-net shape manufacturing. Background technique [0002] At present, the relatively mature methods for preparing spherical metal and alloy spherical powders at home and abroad mainly include inert gas atomization method and plasma gun rotating electrode method. The inclusions in the powder particles prepared by the plasma gun rotating electrode atomization process mainly include heterometallic and non-metallic inclusions. The heterometallic inclusions are magnetic and mainly come from the plasma rotating electrode atomization chamber, which can be removed by magnetic separation device; Part of the metal inclusions comes from the ceramics and slag of the master alloy, and the other part comes from the sealing device of the powder making equipment. [0003] Powder particle mor...
