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
