针对以往湿平整轧制过程中平整液流量采用上、下辊缝等流量的设定方法,不但造成带钢上下表面延伸、粗糙度、耐蚀性以及清洁度存在差异,而且上辊缝平整液流量存在浪费问题,充分考虑到湿平整轧制的设备与工艺特点,提出了一套适合于湿平整轧制过程的平整液流量差异性优化设定技术,通过对上、下辊缝的平整液采用差异化的流量设定,在保证带钢的整体延伸、粗糙度复印、耐蚀以及清洁度的前提下,优化上、下辊缝平整液的流量分配,降低带钢上、下表面延伸、粗糙度、耐蚀性以及清洁度的差异,减少上辊缝平整液的浪费,最大程度的降低平整液的总消耗以及废液处理成本,达到节能减排、经济环保的目的。相关技术被投入到现场应用后,效果良好,为机组创造了较大的经济效益。
Aiming at the setting method of upper and lower roll seam flow rate in the previous wet-leveled rolling process, not only the upper and lower surface of the strip is extended, the roughness, corrosion resistance and cleanliness are different, The flow has the waste problem, has fully considered the wet leveled rolling the equipment and the craft characteristic, has put forward a set of suitable to the wet leveler rolling process the flat liquid flow disparity optimization hypothesis technology, through to the upper and the lower roller crevice liquid Adopting differential flow setting, under the precondition of ensuring the overall extension of the strip, roughness copy, corrosion resistance and cleanliness, the flow distribution of the liquid in the upper and lower rolls is optimized to reduce the upper and lower surface extension of the strip, Roughness, corrosion resistance and cleanliness differences to reduce the upper roller seam liquid waste, to reduce the total consumption of flat liquid and waste disposal costs, to achieve energy-saving emission reduction, economic and environmental purposes. Related technologies have been put into the field application, the effect is good, for the crew to create greater economic benefits.
