摘　　要：针对带钢连续退火过程中的热瓢曲问题,结合连续退火机组的设备特征及生产工艺特点,克服以往研究中忽略炉辊转动对与炉辊接触部分带钢受力影响的弊端;提出带钢上第一、第二横向压应力区的概念,运用非线性有限元软件MSC.Marc以加热段为例,对连退过程中带钢的受力和变形情况进行动态模拟,详细分析热瓢曲发生与发展的过程及其产生机理,为现场热瓢曲的治理,提供了有益的参考。In allusion to the problem of strip wrinkling in continuous annealing process,taking into account the equipment and technology characteristics of CAPL（continuous annealing production line）,the concept of the first and second transverse compressive zone was advanced.The effect of the rotation of furnace roller on the force at the contacting part of strip which was neglected before was considered.The force and deformation of strip in heating zone of CAPL was simulated using nonlinear finite element software MARC.The formation and development of buckling and its emergence mechanism were analyzed in detail,which can provide useful reference for management at spot.
