AI Technical Summary

Technical Problem

Existing vacuum induction gas atomization powder production equipment suffers from high energy consumption, high oxygen content, and poor powder quality due to its tall tower design. Furthermore, droplet collisions during atomization result in irregularly shaped powders, affecting 3D printing quality. At the same time, the height of the equipment limits its large-scale production capacity.

Method used

A flow guide tube combined with an electrode ring is used to make the droplets positively charged, and the principle of like charge repulsion is used to avoid collisions; a cooling air ring and a water cooling plate are added for dual cooling, and an AC extinguishing device is installed to eliminate positive charge; a cyclone separator and a sorting mechanism are set up for efficient grading and sorting.

Benefits of technology

It improves the sphericity and flowability of powder, reduces production costs and energy consumption, enhances the density and product quality of 3D printing, and meets the needs of large-scale production.

Abstract

This invention provides a vacuum induction gas atomization powder making device, belonging to the field of metal powder atomization preparation technology; it includes: a frame, an atomization tower disposed inside the frame; a cyclone separator disposed inside the frame and connected to the discharge end of the atomization tower; a sorting mechanism disposed inside the frame and connected to the discharge end of the cyclone separator; and a melting mechanism disposed at the top of the frame and connected to the feed end of the atomization tower. This vacuum induction gas atomization powder making device, by adding electrode rings, applies a positive charge before the molten metal is atomized and sprayed out, so that all atomized metal droplets are positively charged. Based on the principle of repulsion between like charges, these positively charged droplets will generate repulsive forces during their fall, thereby effectively avoiding collisions and adhesion between droplets. This design can significantly reduce the generation of irregularly shaped powders and improve the sphericity and surface smoothness of the powder.
