Abstract

The application discloses a ring-hole type atomization spray disc assembly for metal atomization powder production, and belongs to the technical field of metal powder production. The ring-hole type atomization spray disc assembly comprises an integral octagonal base with an atomization gas distribution cavity, a ring-shaped spray disc body and a plurality of circumferentially spaced independent nozzles. After being uniformly distributed by the distribution cavity, the atomization gas forms a plurality of discrete high-speed jets through the independent nozzles, and the molten metal is subjected to multi-point collaborative atomization and fragmentation. Through the above design, the discrete nozzles replace the traditional continuous annular slit, the gas distribution and the jet function are decoupled, the design of the adjustable nozzle angle, the split type sealing and the ceramic-metal composite wear-resistant structure is supplemented, the fragmentation capacity for high-viscosity and high-surface-tension melts is greatly improved, the problems of unstable atomization, low fine powder yield and high maintenance cost in the prior art are solved, and the ring-hole type atomization spray disc assembly can be widely applied to the large-scale production of various high-quality metal and alloy powders.
