末端轻压下技术对减少中心偏析很有效，对提高产品质量、生产高附加值产品有重要意义。
It is concluded that this technology is effective to abate central segregation, improve quality of product, produce high value added product.
在铸坯凝固末端轻压下直接作用区域，两相区受到压缩，枝晶间富含溶质的液相被挤出，相对于铸坯向液芯方向流动。轻压下之后，铸坯中心区域由糊状区内被压缩的固相及残留的液相构成，中心区域偏析指数下降。
The simulation results show that mushy region is compressed and interdendritic solute-rich liquid flows toward the liquid core in the soft reduction action zone at the solidification end of the slab.
