Abstract

The invention provides a preparation method for fine metal powder and equipment achieving the method. On the one hand, metal materials are fused and atomized into liquid drops to be sprayed to a high-speed rotation disc and smashed into small liquid drops, and the center spraying axis of the liquid drops is perpendicular to the rotation disc face; on the other hand, the liquid drops sprayed to the high-speed rotation disc are cooled after being smashed, and the metal powder is obtained. Compared with the prior art, the metal powder prepared through the method is fine in grain size, good in degree of sphericity and narrow in grain size distribution range and has good application prospects.

Description

technical field

[0001] The invention relates to the technical field of metal powder preparation, in particular to a method for preparing fine metal powder and equipment for realizing the method. Background technique

[0002] As a kind of powder material, the high-performance functional powder material itself has certain physical and chemical characteristics, such as excellent mechanical properties, special magnetic properties, high electrical conductivity and diffusivity, high reactivity and catalytic properties, and electromagnetic wave absorption. In addition, the characteristics of powder materials: small particle size, large specific surface area, and many properties different from conventional materials can effectively improve the performance of materials and reduce production costs, so that high-performance functional powder materials are gradually being widely used. , especially in the context of global resource and energy shortages, all kinds of high-tech products ar...
