Title (EN) METAL POWDER MANUFACTURING DEVICE AND METAL POWDER MANUFACTURING METHOD
(FR) DISPOSITIF DE FABRICATION DE POUDRE MÉTALLIQUE ET PROCÉDÉ DE FABRICATION DE POUDRE MÉTALLIQUE
(JA) 金属粉末製造装置、及び金属粉末の製造方法
Abstract:
(EN) Provided are a metal powder manufacturing device and a metal powder manufacturing method that enable a high-quality small-particle-diameter metal powder to be obtained. An ultrasonic flame is jetted in a focused manner onto dropped molten metal, the focused flame is made into a discharge focused flow and discharged directly downward, the discharge focused flow is made to plunge into a swirling water flow formed along an inner circumferential surface of a granulating cooling tube the axis of which is inclined relative to the vertical direction, and the focal position of the flame is made to be located in an open space above the swirling water flow.
(FR) L'invention concerne un dispositif de fabrication de poudre métallique et un procédé de fabrication de poudre métallique qui permettent d'obtenir une poudre métallique de petit diamètre de particule de grande qualité. Une flamme ultrasonore est projetée de manière focalisée sur du métal fondu que l'on fait tomber, la flamme focalisée est transformée en un flux focalisé de décharge et déchargée directement vers le bas, le flux focalisé de décharge est amené à plonger dans un écoulement d'eau tourbillonnante formé le long d'une surface circonférentielle interne d'un tube de refroidissement de granulation dont l'axe est incliné par rapport à la direction verticale, et la position focale de la flamme est amenée à être située dans un espace ouvert au-dessus du flux d'eau tourbillonnante.
(JA) 品質のよい微細な粒径の金属粉末を得ることが可能な、金属粉末製造装置、及び金属粉末製造方法を提供する。 垂下した溶融金属に、超音速の燃焼炎を集中噴射し、集中した前記燃焼炎を噴出集束流にして直下に噴出し、前記噴出集束流を、軸線が鉛直方向から傾斜した粉砕冷却筒の内周面に沿って形成した旋回水流に突入させると共に、前記燃焼炎の集中位置を、前記旋回水流より上方の開放空間中とする。
