Title (EN) GAS ATOMIZATION NOZZLE AND GAS ATOMIZATION DEVICE
(FR) BUSE D'ATOMISATION DE GAZ ET DISPOSITIF D'ATOMISATION DE GAZ
(JA) ガスアトマイズ用ノズルおよびガスアトマイズ装置
Abstract:
(EN) The purpose of the present invention is to generate fine powder with less variation in particle size. Provided is a gas atomization nozzle comprising: a through-hole (3A) formed along a center line (C); a nozzle portion (3D) configured as a Laval nozzle, which is disposed along a periphery of the center line (C) and inclined at a predetermined angle (α) with respect to the center line (C); and a swirling motion imparting means for imparting a swirling flow around the center line (C) to gas emitted from the nozzle portion (3D).
(FR) L’invention a pour but de générer une poudre fine avec moins de variation de la taille des particules. L'invention concerne une buse d'atomisation de gaz comprenant : un trou traversant (3A) formé le long d'une ligne centrale (C) ; une partie buse (3D) configurée sous la forme d'une tuyère de Laval, qui est disposée le long d'une périphérie de la ligne centrale (C) et inclinée selon un angle prédéterminé (α) par rapport à la ligne centrale (C) ; et un moyen de transmission de mouvement tourbillonnant pour conférer un écoulement tourbillonnant autour de la ligne centrale (C) à un gaz émis à partir de la partie buse (3D).
(JA) 粒度のばらつきの少ない微細粉末を生成する。中心線(C)に沿って形成された貫通穴(3A)と、中心線(C)の周りに沿って配置されて中心線(C)に向き所定角度(α)傾けて設けられたラバルノズルからなるノズル部(3D)と、ノズル部(3D)から噴射されるガスに中心線(C)を中心とする旋回流れを付与する旋回付与手段と、を備える。
