摘要：

Aiming at the problems that traditional looper control systems could not meet the requirements of practical productions, the calculation method of looper motor torques and the detection methods of tension were given according to looper currents, the optimal control strategies of loopers were put forward based on the soft touch method, no whip control method and flow compensation method. The optimized looper control system was applied in a hot strip mill, and the practical application results show that with the specification of 3.0 mm×520 mm, the angles of loopers may be controlled within the target tolerances of ±2°, the currents of loopers may be controlled within the target tolerances of ±5%. The thickness may be controlled within the allowable thickness deviation of ±40 μm over 98.7%, and the strip width deviation may be controlled within the target tolerances of 0~4 mm over 96.9% of the strip steels and the precision of strip head and tail is enhanced. © 2017, China Mechanical Engineering Magazine Office.
