摘　　要：连铸坯轻压下技术不但可以减轻中心疏松和偏析,而且还可以改善铸坯的凝固特性。本文简述了连铸坯中心偏析的形成机理,介绍了轻压下的系统参数,阐述了轻压下的发展历程,并对轻压下技术的发展方向进行了展望。The soft reduction technology of continuous casting billet can not only reduce the center porosity and segregation, but also improve the solidification characteristics of the casting billet. The formation mechanism of central segregation of continuous casting billet was briefly described. The system parameters of soft reduction were introduced. The development process of soft reduction was described. The development direction of the soft reduction technology was prospected.
