摘　　要：现场跟踪发现,带钢经过连续退火炉的板形变化复杂多样,而且其程度不亚于轧制过程。为此运用带钢的板形屈曲及后屈曲理论,分析了退火炉内高温态下带钢的板形屈曲临界条件,结合板形生成理论,指出退火炉内带钢板形发生变化的原因和主要相关因素。According to the examining data from a CAPL in Baosteel,the strip shape varied complicatedly and markedly while passing through the continuous annealing furnace,nearly to the extent of the rolling process.The buckling criteria of the strip profile deformation at high temperature in the continuous annealing furnace was analyzed by the theories of strip buckling and post-buckling; the reason and correlative influencing factors of the strip shape variation in continuous annealing furnace were presented on the basis of the shape creation principle.
