摘　　要：结晶器铜板表面与各导辊顶部的包络线精度即对弧精度以及各导辊的辊缝精度构成了辊列的主要精度。影响辊列对弧精度的主要原因是扇形段（ＳＥＧ）刚性劣化，ＳＥＧ机内安装与维护不良，ＳＥＧ机外对中及对弧样板精度有偏差以及全线对弧周期管理不当等。宝钢连铸机投产６年后曾一度精度劣化，采取有效措施后，使全线对弧精度≤０．５ｍｍ的比率达到了９２％以上。Roll configuration main precision includes wildhaber precision (ie:precision of subtended) between the surface of mould cupric and the top of every guide roller,and roller slot of everyguide roller.The main reason about influence on precision of subtended arc is worsing segment stiffness,poor maintance and installation inside SEG,defect of alignment outside SEG and sample precision of subtended arc,inproper perioderical management on all subtended arc and so on.The precision was once found to worse six years after continuous casting machine was put into producing.After taking effective measures,the ratio of all precision of subtended arc has reached above 92%.
