摘　　要：瓢曲是连续退火炉内普遍存在的问题,当带钢经过凸度辊时,由于炉辊凸度的存在,在张力作用下,发生横向压缩而形成的一种与带钢长度方向平行的质量缺陷。运用数值模拟的方法分析计算凸度辊中间平台区宽度、带钢宽度及张力等因素对瓢曲发生的影响,并得到临界瓢曲张力公式,为预测瓢曲的发生提供理论参考。Buckling is a common problem in continuous annealing furnace. When strip runs over tapered rollers under global tension, it retrieved its initial width, a quality defect which is paralleled to the length direction of strip was formed. Numerical simulation was used to analysis and calculate the effect of tapered rolls＇middle platform width, strip width, tension and so on. To predict whether there is strip buckling, the formulation of critical buckling tension provides a theoretical basis.
