采用有限元分析软件DEFORM-3D对1060铝板在热轧过程中的疲劳损伤进行模拟,分析了第一道次轧制中疲劳损伤因子的分布。对正交实验得出的若干组热轧方案进行了分析对比,得出较优结论并解析其原因,讨论了解决方案。结果表明:第一道次轧制的疲劳损伤主要累积在轧件边部中心;最优方案为压下量22.5 mm,轧辊温度80℃,轧件温度380℃,轧制速度25 r/min;疲劳损伤随着轧制的进行逐渐增大,在0.3~0.35 s达到最大,此后不再发生变化。 The finite element analysis software DEFORM-3D was used to simulate the fatigue damage of 1060 aluminum plate during hot rolling. The distribution of fatigue damage factor in the first pass rolling was analyzed. A number of hot rolling programs obtained from the orthogonal experiments were analyzed and compared, the better conclusions were drawn and the reasons were analyzed, and the solutions were discussed. The results show that the fatigue damage of the first pass rolling mainly accumulates in the center of the rolling edge. The optimal plan is rolling reduction of 22.5 mm, roll temperature of 80 ° C, rolling temperature of 380 ° C and rolling speed of 25 r / min. The fatigue damage gradually increases with the rolling, reaching the maximum at 0.3 ~ 0.35 s, and then no change occurs.
