Development of camber and steering control system in hot strip mill

Camber and off-center in hot strip rolling process cause various problems including clogging, defects on the strip, and telescope phenomenon in a coil. To reduce camber and prevent off-center, we propose the integrated camber and steering control system based on adjusting roll gap level by previously designed mathematical model. By considering difficulties in the measurement and knowhow in the operation of plants, we improve measuring position and control methods in the system. We apply it to real plants and show the effectiveness of the system.
