Description

Technical Field

[0001] The present invention relates to the technical field of gas atomization powder making, and more specifically to a gas atomization device and method for reducing the process cost of gas atomization powder making. Background Art

[0002] In traditional gas atomization devices, the pneumatic nozzle layout is single, mostly simple fixed arrangement, which makes it difficult to take into account different powder making needs. When conventional distribution is adopted, the atomization effect in the central area is not ideal, the overall atomization area utilization rate is low, and a large amount of molten metal cannot be fully atomized, which not only wastes raw materials but also affects production capacity; When the pneumatic nozzles are arranged in a ring, the nozzles are distributed in a circle around the center, impacting the molten metal flow from all sides; this method can enhance the atomization effect in the central area to a certain extent, because the airflows of multiple nozzles are superimposed in the central area, so that the molten metal in the central area is subjected to a stronger fragmentation effect; however, due to the lack of an effective spray direction adjustment mechanism in the traditional ring arrangement, it is impossible to achieve all-round uniform atomization, and there is still a problem of uneven atomization in some angles and areas; When the pneumatic nozzles are arranged in a spiral pattern, the path and time of gas-liquid interaction can be extended to a certain extent by arranging the nozzles along the trajectory of the spiral line, thereby enhancing the gas-liquid mixing effect. However, in traditional devices, the spray direction of the spirally arranged nozzles is fixed and cannot be optimized according to actual production needs, resulting in limitations in optimizing particle size distribution and improving particle conveying efficiency. The advantages of the spiral arrangement cannot be fully utilized, which affects the efficiency and quality of aerosol powder making. The pneumatic nozzle arrangement of the existing aerosolization device is single, and it is difficult to flexibly adjust according to different powder making requirements and metal material properties; when faced with diversified production tasks, it is unable to give full play to the advantages of aerosol powder making, which limits the improvement of production efficiency and product quality.
