Apparatus and method for preparing spherical metal powder based on one-by-one atomization method for uniform droplets
An apparatus includes a housing, a crucible disposed in the housing, and a collection bin. A turnplate disposed in a powder collection area is of an inlaid structure. A concentric circular groove is provided on the atomization plane. An air hole is provided in the turnplate. The present invention combines the pulsated orifice ejection method and the centrifugal atomization method, in cooperation with the turnplate structure and subjecting the turnplate surface to induction heating, so that a metal liquid is allowed to break through the split mode of traditional molten metal, achieves a fibrous split mode that can be implemented only when an atomizing medium is an aqueous or organic solution, and prepares a high-melting-point metal powder that meets requirements, and has a controllable particle size, high sphericity, no satellite droplets, and good flowability and spreadability, and is suitable for industrial production.
