| 摘 要： | 回转水纺丝法是一种制备圆形戳面光滑连续细丝的新技术．喷射速度是重要工艺参数之一．对Ｆｅ－Ｓｉ－Ｂ合金，当喷射速度过小时．只的得到缩颈状丝或粉丝历位．当喷射速度与水层速度之比Ｖｊ／Ｖｗ大于１．１９时，只能得到弯曲状细丝当Ｖｊ／Ｖｗ小于１．０６时，得到短丝．仅当Ｖｊ／Ｖｗ在１．１１—１．１６之间，才能得到光滑连续细丝．

| Abstract: | In-Rotating-Water Spinning Method is a kind of advancd technique which canproduce smooth and continuous wires with round cross-section. The ejection velocity is one of themost hopohant parameters. For Fe-5. 05Si-2. 89B alloys, if ejection velocity is small, neckwires or spherical grains are obtained. If the vdocity rate Vj/Vw is above 1. 19, where Vj is the ejection yelocity and Vw is the tangental velocity of the water surface, wires are obtained. If thevelocity ratio Vj/Vw is below 1. 06,short ones are obtained. Only when the velocity ratio Vi/Vw isin the range from 1. 11 to 1. 16, smooth and continuous wires are obtained. |
