近年来,为了满足各工业交通部门对钢材的质量和性能提出的越来越严格的要求,国内外采用了许多炉外精炼方法。钢包内吹氩气处理钢水(简称吹氩)是其中的一种。这种方法装置简单、消耗低、上马快,并可以明显地净化钢质,改善注况,提高钢材质量,因而得到了广泛采用。 In recent years, in order to meet the increasingly stringent requirements put forward by various industrial transportation departments on the quality and performance of steel products, many overseas refining methods have been adopted. Ladle argon gas treatment of molten steel (referred to as blowing argon) is one of them. This method is simple, low consumption, quick start, and can significantly purify the steel, improve the note, improve the quality of steel, which has been widely used.
