Looper Shape Meter (LSM)

Advanced strip-shape monitoring and control method

Special looper at finishing mill interstand
Measures strip tension's distribution along strip width
Installation by replacing existing conventional looper
Durability of LSM is verified on an actual line under harsh conditions of hot rolling
Provides shape and off-center information for most of the length of the strip
Improved strip shape thanks to timely feedback control
Fewer pinching problems at strip tail-end by detecting abnormal strip tension and feedback
