摘    要：采用Ansys有限元软件对连续退火/热镀锌机组上带钢稳定通板进行了系统的研究。通过Ansys模拟计算系统分析并阐明了横向压缩应力的产生机制,研究了其随着各种参数的变化规律,得出了带钢张力、炉辊凸度、平台区长度等对带钢传输过程中横向压缩应力分布的影响规律,预测了带钢发生瓢曲的可能性。仿真所得出的一系列结论为实际生产中辊形的设计与选择提供了理论依据,以便更有效地控制跑偏和瓢曲的产生,解决生产中的实际问题。

Abstract: Strip pass technique on continuous annealing/hot galvanizing line(CAL/CGL) was systemic studied by the finite element analysis software(Ansys).Through the calculation of Ansys,the law of transverse compressive stress was investigated with the different parameters,and the mechanism of transverse compressive stress was put forward.The results from finite element model revealed the influence of strip tension,roll crown,roll flat part on the transverse compressive stress during the strip conveying and could predict the probability of the strip buckling.Furthermore,conclusions obtained from simulations provide academic guidance for roll design and selection in practice,which will help to effectively control of misguiding and buckling and to solve practical problems.
