(一) 前言喷射冶金技术是70年代发展起来的一种不涉及真空条件,然而也可以达到部分精炼效果的冶金手段。通过对钢液喷吹各类粉剂的处理,能获得极低氧、硫含量和改善夹杂物形态,消除三氧化二铝链状夹杂的效果,同时可进行易氧化元素和微量元素的合金化。为此受到冶金工作者的普遍重视。 (A) Foreword Jet metallurgy is a metallurgical tool developed in the 1970s that does not involve vacuum conditions, but can also achieve partial refining effects. Through the treatment of all kinds of powder metallurgy, extremely low oxygen and sulfur content can be obtained and the inclusion morphology can be improved, the effect of aluminum oxide chained inclusions can be eliminated, and the alloying of easily oxidizable elements and trace elements can be carried out at the same time. To this end by metallurgical workers generally valued.
