Laser heating rotating atomization method and device used for manufacturing metal or alloy powder

Abstract

The invention relates to a laser heating rotating atomization method and device used for manufacturing metal or alloy powder. A traditional plasma gun is replaced by a single high-power laser (6) or a plurality of high-power lasers (6) focusing in different angles, a bar material is rotated at a high speed through a high-speed motor (5), and the bar material is automatically fed through a material pushing motor (9). Through the structures, a complex connecting mechanism of a traditional carbon brush and a copper electrode is omitted. Using limit of the carbon brush in a plasma rotating atomization device is eliminated, the metal and alloy powder can be manufactured in a carbon brush-free mode, the phenomena of frictional heating of the carbon brush and wear to the carbon brush are eliminated, and therefore the limit speed of the bar material is effectively increased, dust and noise pollution is greatly reduced, device stability is enhanced remarkably, and work efficiency is improved. The method and device can be applied to the field of manufacturing the metal or alloy powder through an atomization method.

Description

technical field [0001] The invention relates to the field of laser heating rotary atomization powder making, in particular to a laser heating rotary atomization method and equipment suitable for preparing various metal or alloy powders. Background technique [0002] With the rapid development of the national economy, the demand for high-performance metal and alloy structural parts in many fields such as aerospace, military industry, nuclear power engineering, and deep-sea exploration is increasing day by day, and the performance requirements are becoming increasingly stringent. According to the use requirements of future industrial development, to achieve a substantial leap in performance, 70-80% depends on the preparation of high-performance powder materials. Therefore, the requirements for materials in high-end structural parts in the next century will no longer be satisfied with traditional materials. Incremental improvement, but requires the opening up of new material sy...
