アトマイズ鉄粉の製造とその粉末冶金的特性

On the Production and Powder Metallurgical Characteristics of the Atomized Iron Powders

岸 高 寿(Hisashi Kishitaka) 森岡 恭昭(Yasuaki Morioka) 田村 皖司(Kiyoji Tamura) 要旨 : 水アトマイズ鉄粉の製造過程の原理，製造装置およびその粉末冶金的特性について解説し た。アトマイズの過程についてその化学工学的な理論が検討され，また得られた粉末粒子 の平均粒径とアトマイズ条件との関係が述べられた。粉末冶金的特性についてはアトマイ ズ法およびその他の方法でつくられた鉄粉の間の性質の違いが検討された。また試作され た合金鋼アトマイズ粉の特性が示された。 Synopsis :

The principle of the process and the equipment for the production of water atomized iron powders, as well as powder metallurgical characteristics of the products, are explained. The process of atomization has been investigated from the viewpoint of the theories of chemical engineering, and the relation between the average diameter of produced powder particles and the condition of atomization has been described. On the powder metallurgical characteristics, the difference between the qualities of the iron powders which are produced by atomization and by the method, together with the characteristics of the atomized alloy steel powders, has also been described.
