摘　　要：通过现场生产实践对钢轨轧制过程产生的不对称缺陷进行了收集、分析,结合热态轮廓仪自动检查结果,分析其产生的主要原因为轧辊辊箱装配、咬入、抛钢时轴向窜动,孔型设计不合理等。针对以上原因制定了相应的措施,以有效解决钢轨通长对称缺陷。Through collecting and analyzing the asymmetric defects generated during the rail rolling practice based on the actual production on site,and combining with the automatic inspection of the thermal profiler,the main reasons for their occurrence are analyzed:roller box assembly,biting,axial movement during steel throwing,and pass design are illogical.Based on the above reasons,corresponding measures have been formulated to effectively solve the defect of symmetrical rail length.

关 键 词：轴向窜动 自动检测 孔型
