摘　　要：把连铸坯带液芯轻压下视为由坯壳侧壁的轧制变形和坯壳大面的弯曲变形两部分组成。分别推导上述两个过程的附加拉坯力。讨论了影响各道次附加拉坯力的因素。It is considered that the soft reduction of strand with liquid core is consisted of the reductions caused by rolling of side faces and bending of wide faces respectivelyThe additional drawing force for such processes is deducted respectivelyThe factors influencing on total additional drawing force are discussed brieflyThe compatible strain and creep in shell is also analysed

关 键 词：轻压下 拉坯阻力 连铸坯
