针对某钢铁公司连退双机架湿平整机组生产R2级表面镀锡板工作辊表面粗糙度衰减速度快、轧制公里数偏低的问题,充分考虑到连退双机架湿平整机组的设备与工艺特点,从轧制工艺、轧辊使用工艺两方面深入分析了问题产生的原因,通过优化1#及2#机架工作辊原始表面粗糙度及伸长率分配系数建立了一套工作辊表面粗糙度衰减控制模型,并将模型应用到生产实践,大大降低了工作辊表面粗糙度的衰减速度,提高了轧制公里数,为企业创造了较大的经济效益。
Aiming at the problem that the surface roughness of R2-surface tinplate work roll produced by a steel company with double-rack wet-flattening unit is decayed quickly and the rolled kilometer is too low, taking full consideration of the equipment of double flat wetting-leveling unit And process characteristics, the causes of the problems are analyzed in depth from two aspects of the rolling process and the roll using process. A set of work roll surface is established by optimizing the original surface roughness and the elongation distribution coefficient of the work rolls of No. 1 and No. 2 work stands Roughness attenuation control model, and the model applied to the production practice, greatly reducing the work roll surface roughness decay rate, increased rolling kilometers, for enterprises to create greater economic benefits.
