气雾化微细金属粉末的生产工艺研究

Research of Producing procedure of Fine Metal Powder by gas Atomization

介绍了气雾化微细金属粉末的生产工艺。金属熔炼、雾化制粉，粉末分级及收集都是在保护气氛中进行，气体喷嘴和漏液嘴紧密耦合并用高压气体雾化。生产的金属粉末颗粒为球形，流动性好，氧含量低，细粉收得率高，可为粉末冶金及相关行业提供优质的金属粉末原料。

This paper discussed the process of the sas atomization of fine metal powder. The powder,which has been produced by means of close-coupled high-pressure gas atomization,is spherical. The powder has good flowability and low oxygen content. The collection efficiency of the fine POwder is high. The metal POwder of excellent quality is available for POwder metallurgy and other relative industry.
