Problems solved by technology

Taking titanium alloy powder as an example, the current yield of rotating electrode powder with a particle size of less than 100 μm is less than 40%. The coarser powder particle size limits the application of rotating electrode powder making technology in the field of 3D printing.

Abstract

The embodiment of the invention relates to a device and method for preparing fine particle size metal powder through local melting of particles. The device comprises an atomizing chamber, a powder feeding mechanism, a heat source, a rotating mechanism and a driving mechanism, wherein the powder feeding mechanism is used for feeding first metal powder into the atomizing chamber; the heating part ofthe heat source is arranged in the atomizing chamber and used for melting the first metal powder into second metal powder with the periphery in a liquid state; the rotating part of the rotating mechanism extends into the atomizing chamber and receives the second metal powder falling to the surface of the rotating part; and the driving mechanism is connected with the rotating mechanism, and the driving mechanism drives the rotating part to rotate to generate centrifugal force to crush the second metal powder into a plurality of third metal powder. According to the device and method, the coarseparticle size metal powder can be subjected to secondary crushing to prepare fine particle size metal powder, the quality and yield of the fine particle size metal powder can be increased, and the application range of the metal powder is expanded.

Description

technical field [0001] The embodiments of the present disclosure relate to the technical field of powder metallurgy, and in particular to a device and method for preparing fine-grained metal powder by partial melting of particles. Background technique [0002] In recent years, with the development of powder metallurgy technologies such as hot isostatic pressing, metal additive manufacturing, and injection molding, the demand for metal powder has also grown rapidly; at the same time, with the development of new technologies such as metal additive manufacturing technology, the demand for metal The quality of the powder, especially the particle size distribution, puts forward higher requirements. The 3D printing technology represented by the powder bed selective fusion forming mainly focuses on the particle size of the metal powder in the range of 15-100 μm. [0003] At present, the production technologies of metal powder mainly include gas atomization powder making, plasma fus...
