轻压下技术是减轻铸坯中心偏析,提高内部质量最为有效的方法。以三明钢厂220×1600mm板坯连铸机轻压下技术的实施为背景,对轻压下涉及的扇形段及铸坯的变形进行研究,合理设计了辊缝补偿量并在实际生产中采用,取得了很好的压下效果。 Soft reduction technology is to reduce the slab center segregation, improve the internal quality of the most effective way. Based on the implementation of the technology of soft reduction of 220 × 1600mm slab caster in Sanming Steel Mill, the deformation of the segments and billets involved in the light pressure was studied. The compensation of the roll gap was designed reasonably and used in actual production , Made a very good reduction effect.
