摘要
为提高板形控制效果,以板形最优为目标,建立了一套冷轧带钢平整机支撑辊辊型优化模型。为提高寻优速度,将目标函数进行转化,避免了金属模型与辊系模型的迭代计算,有效降低了计算时间,增加了算法的强壮性。将优化结果应用于凌钢900 mm平整机,生产实践表明,优化辊型可明显增强轧机的板形控制能力,降低弯辊负担,改善板形控制效果。
To improve the precision of shape controlling,taking
best shape as object function,a set of models were developed for optimizing
backup roll contour of temper rolling mill.To optimize calculation speed,the
original object function was transformed into another form,which avoided the
coupling calculation between metal model and rolls model,obviously decreased
calculation time and increased models' robustness.The optimization result was
used in 900 mm temper rolling mill of Ling Steel.Productive practice shows
that shape control ability of the mill is apparently enhanced,and the bending
force is decreased,and the effect of shape control is enhanced.
