摘要
铸坯在连铸生产过程中很容易产生中心偏析和中心疏松缺陷,其质量对后续的轧材产生直接的影响。随着近年来人们的不断摸索研究,在连铸方面开发了许多改善铸坯质量的新技术,其中最为行之有效的一种便是轻压下技术。为此综述了轻压下技术的基本原理,对其各项工艺参数进行了理论分析选择,并对该技术在国内外企业的应用和发展方向做了一定的阐述和讨论。
It is very easy to produce center segregation and center porosity defects in continuous casting process,the quality of the followed products is impacted by the slab or billet.As more research in the field in recent years,a number of methods to improve the quality of products are proposed in the continuous casting,the most effective one is the soft reduction technology.This paper reviews the basic principles of soft reduction technology,the makes theory analysis choice to their technological parameters,moreover explains and discusses the application and development direction of this technology in domestic and foreign plants.
