摘　　要：介绍了国内外薄板坯连铸连轧流程中液芯压下技术的发展与应用情况，分析了液芯压下过程中铸坯的凝固机理以及变形和应变特点，并根据铸坯的凝固机理和坯壳凝固前沿的应变条件，提出了确定单辊压下量、压下量分配和总压下量的基本方法。The paper introduces the development and application of soft reduction with liquid core in thin slab continuous casting/rolling process abroad,the principle of solidification,the deformation and strain of slab during soft reduction with liquid core is analyzed,the basic method of determining the total reduction ratio,the reduction ratio at one roll and the distribution of reduction among segments is put forward
