Quadric injection metal atomization device of rotary-forming film

Abstract

The invention relates to a metal atomization device for the secondary injection of a rotary film, which comprises an input liquid metal jet supplying part; a ring-shaped atomization combined nozzle is formed concentrically with an input liquid metal jet center; a rotating impact platform is arranged at the lower part of the ring-shaped atomization combined nozzle which is provided with an upper nozzle and a lower nozzle; the airstream jetting direction of the upper nozzle is in a downward centrifugal direction to impact the rotary film formed when the impact platform is impacted by the input metal jet, thereby breaking a formed film; the airstream jetting direction of the lower nozzle is in a downward central direction and forms an effective cross angle with the airstream jetting direction of the upper nozzle, thereby impacting the broken liquid metal particles of the formed film and realizing secondary breaking. By adopting the device, better atomization effect and finer metal droplets and powders can be obtained.

Description

Spin film secondary spray metal atomization device Technical field: The invention relates to a metal atomization device, in particular to a metal atomization device for spinning film secondary injection. Background technique: Powder metallurgy and spray forming technology have become an important pillar and a very promising industry in the electromechanical manufacturing and processing industry. Powder metallurgy materials are favored by the metal product manufacturing industry due to the advantages of energy saving, material saving, low cost of large-scale production, and no need for machining. Metal injection molding (MIM) and thermal spraying (TS) derived from it , metal rapid prototyping (metal rapid prototyping, MRP), surface mount technology (surface mount technology, SMT) and other technologies have been vigorously developed. The spray forming technology is an advanced semi-solid metal processing technology developed in the past 20 to 30 years. It can not only over...

Problems solved by technology

In recent years, researchers in my country have also conducted a lot of research on gas atomization technology, and have made great progress, but there is still a gap in the yield of fine metal powder (less than 20 μm), and key technologies still need to be imported from abroad.
