Abstract
Taking MH UCMW cold tandem mill as research object, broken edge wave generating mechanism and characteristics were analyzed which caused by edge drop control. Based on original control strategy, an automatic edge wave control model was developed, and edge drop control strategy was optimized. Effect of taper work roll shifting and taper shape on broken edge wave were analyzed by actual rolling data. Results show that broken edge wave decreases with effective contact depth increasing of taper work roller and strip. Optimized control system application eliminate broken edge wave, and improve automatic shape control accuracy.
