摘　　要：结合辊缝实际测量数据和扇形段结构特征的分析,查明了引起板坯铸机扇形段内部辊缝变大的主要原因。基于扇形段内弧辊架梁受力特征的分析,提出了一种扇形段预变形优化方法。按照扇形段内部辊缝变大的程度确定铸机实施调整的区域,实施后将扇形段内部辊缝增大量控制在0.2mm以内。Combined the analysis of measured roll gaps with the structure of segments of the slab caster at No. 2 Steelmaking Plant of Shougang, the main causes of the inner gap enlargement were released. Based on the stress analysis of inner roll beams , the optimization method for segment prede- formation was put forward. Adjusted region in the segment was confirmed according to the increments of the inner roll gaps and they could be controlled within 0.2mm when the new method was adopted.
