Combined type gas atomization powder preparation equipment

Abstract

The invention discloses combined type gas atomization powder preparation equipment, and relates to the technical field of metal powder material preparation. The combined type gas atomization powder preparation equipment comprises a feeding system, a smelting system, an atomizing system, a circulating gas system and an ultrasonic generator which are connected in sequence. The smelting system comprises a smelting chamber and a heating coil, and the heating coil is arranged on the outer side of the free end of a metal material rod in a sleeved manner; the atomizing system comprises an atomizing chamber and an atomizing spray disc; the circulating gas system comprises a plurality of blowing mechanisms which are arranged in a sleeved mode; the blowing mechanisms comprises an annular pipe and anair blowing opening, wherein the air blowing opening is arranged on the annular pipe at intervals, and the air blowing opening is inclined downwards and points to the center line of the annular pipe.the blowing mechanisms are additionally arranged on the top wall of the atomizing chamber through the combined type gas atomization powder preparation equipment, the ultrasonic generator is arrangedon the inner wall of the atomizing chamber, and ultrasonic waves emitted by the ultrasonic generator can be used for dispersing and crushing molten metal droplets into finer powder. The composite gasatomization powder preparation equipment can reduce the occurrence of a satellite ball, and can improve the yield of fine powder and reduce the oxygen content of powder.

Description

technical field [0001] The invention relates to the technical field of metal powder material preparation, in particular to a composite gas atomization powder making equipment. Background technique [0002] Metal powder refers to metal particles with a size less than 1mm, including single metal powder, alloy powder and certain refractory compound powders with metallic properties, and is the main raw material for powder metallurgy. At present, with the development of science and technology, technologies such as injection molding and 3D printing have been developed rapidly. As the raw material of the above technologies, metal powder, its shape, particle size distribution, particle size and purity, etc., can directly affect the quality of injection molding. The quality of technical products such as molding and 3D printing is also an important factor limiting the development of the above technologies.

AI Technical Summary

Problems solved by technology

[0003] In actual production, the purity of metal powder prepared by traditional powder making equipment is not high enough due to the influence of refractory materials, and it is easy to form satellite balls and finally satellite powder during the solidification process of metal droplets falling

The above-mentioned powder materials with low purity and serious satellite powder affect the performance of subsequent processed products
