Abstract

The invention discloses a metal liquid droplet atomization protecting gas hood. The metal liquid droplet atomization protecting gas hood comprises an upper cavity cover, a lower cavity cover, a flow guide pipe and a high-pressure gas channel, wherein the flow guide pipe penetrates through the upper cavity cover and the lower cavity cover, the upper cavity cover and the lower cavity cover are matched to form a high-pressure atomization circumferential seam and a high-pressure chamber, and the high-pressure gas channel is communicated with the high-pressure chamber. The metal liquid droplet atomization protecting gas hood solves the technical problem of blockage of the flow guide pipe due to molten metal coagulation.

Description

technical field [0001] The invention relates to the field of 3D printing additive manufacturing and the field of powder metallurgy, in particular to a metal droplet atomization protective gas shield. Background technique [0002] In recent years, with the development and innovation of processing technology, the application of metal powder in the industrial field has become more and more extensive. It has become a consensus in the industry that high-performance parts need to be prepared by powder. With the application of metal 3D printing technology in the industrial field, the demand for metal powder in metallurgy, energy, electronics, medical, aerospace and other industries is increasing. [0003] At present, the traditional method of producing metal powder at home and abroad is the atomization method, and the key component of the atomization method is the atomizer. The structure of the atomizer will have a great impact on the jet flow field, the design is unreasonable, th...
