引言最近十几年来,世界各先进工业国家大力研究并推广各种真空处理方法。到目前为止,已有的主要真空处理方法有:在盛钢桶中进行钢液的真空处理,钢液柱真空脱气,真空浇注,钢液循还处理,钢液提升处理等。在这些方法中,钢液在盛钢桶中真空处理的方法具有设备简单、处理钢液量不受限制等主要优越性,适合于大量提高钢质量的工业生产要求。此法于1893年由Gusstahl-werk Bochumer verein A.G.建议,而受到冶金工作者的广泛重视,并被应用于生产。经过多年的实践证明,此法对某些钢种有效,但对大多数钢种无明显效果。因此,有必要深入地研究真空处理的物理化学过程及工
Introduction In recent ten years, various advanced industrial countries in the world have made great efforts to study and promote various vacuum treatment methods. So far, the main vacuum treatment methods are as follows: vacuum treatment of molten steel in ladle, vacuum degassing of molten steel column, vacuum pouring, circulation treatment of molten steel, liquid steel lifting treatment and the like. Among these methods, the method of vacuum treatment of molten steel in a ladle has the advantages of simple equipment and unlimited amount of liquid steel to be processed, and is suitable for industrial production in which the quality of steel is greatly increased. This law was proposed by Gusstahl-werk Bochumer verein A.G. in 1893 and was widely valued by metallurgists and applied to production. After years of practice has proved that this method is effective for some types of steel, but no significant effect on most steel. Therefore, it is necessary to study in depth the physical and chemical processes and processes of vacuum processing
