以五机架冷连轧UCMW轧机为研究对象,对实际轧制过程中调节边降产生的碎边浪,分析了其产生机理与特点,对碎边浪的控制策略进行了研究,开发单锥度工作辊窜辊调控碎边浪自动控制模型,对边降整体控制策略进行优化。通过轧制试验,分析了单锥度工作辊窜辊和单锥度工作辊端部辊形对边浪的影响。结果表明,辊形一定,随工作辊端部锥段窜入带钢深度的增加,边浪减小;窜辊值一定,随辊形锥度加深,边浪减小;单锥度工作辊窜辊的边浪调控能力随端部辊形与带钢接触的有效锥度的增加而增加。现场应用消除了碎边浪,提高了板形控制精度。
Taking the five-stand cold rolling UCMW rolling mill as the research object, the mechanism and characteristics of the broken edge wave generated during the side-roll adjustment during the actual rolling process were analyzed, and the control strategy of the broken edge wave was studied. The control model of the working roller for traverse roller control the broken edge wave to optimize the overall control strategy of the side drop. Through the rolling test, the influence of single taper work roll shifting roll and single taper work roll end roll shape on edge waves was analyzed. The results show that the shape of the roll is constant, the edge wave decreases with the increase of the depth of taper of the work roll and the taper of the work roll. The edge conditioning capability increases with the effective taper of the end roll contact with the strip. Field application eliminates the broken edge waves, improved shape control accuracy.
