|
摘要
为了提高机组效率和成品质量,通过分析冷连轧机组轧制过程中容易出现的轧制不稳定现象,在建立了前滑值、打滑因子以及成品粗糙度与工作辊原始表面粗糙度之间一一对应关系的基础上,充分结合冷连轧机组的设备与工艺特点,研究出一套适合于冷连轧机组的工作辊原始表面粗糙度优化技术。通过该技术,在满足用户对产品粗糙度要求的前提下,实现了对前滑、打滑的有效防控,并将其应用到某厂1 420冷连轧机组的生产实践中,大大提高了机组速度和成品带材的表面质量,给现场带来了较大的经济效益。
In order to improve the efficiency and product quality, the one-to-one relationship was established between the forward slip value, slipping factor, product roughness and work roll surface, by the analysis to the rolling instability in the rolling process of cold rolling mill. Then, combining with the equipment and technology feature of cold rolling mill, a set of original surface roughness of work roll optimization technology was set up for cold rolling mill, which can meet the product roughness requirements and achieve forward slip control, slipping prevention. Finally, this optimization model was applied to production practice of 1420 cold rolling mill in a factory, which improved the unit speed and strip surface quality; therefore the technology has brought great economic effect.
