摘　　要：结合大板坯连铸机辊缝实际测量数据和扇形段结构特征的分析，查明了引起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。Based on the analysis of the actual measurement data of roll gap and the structure character of the segment, the key reasons in causing the increase of inner roll gap is examined. And based on the force analysis of the inner roll beam of the segment, one predeformation optimizion method is put forward. By this method, the adjusted region of the continuous caster is decided according to the increment level of the inner roll gap of the segment. In application, the increment of the inner roll gap of the segment is controlled in less than 0. 2 mm.
