Primetals Technologies Japan, Ltd. has developed the contact-type inline strip shape meter (Looper Shape Meter, hereinafter LSM) and has been marketing it for hot strip mills, where continuous inline strip shape measurement is long-awaited. The LSM consists of seven segmented rolls aligned in the width direction. Low hysteresis is obtained by applying torque meters at each segment. An internal water cooling system is employed and sufficient durability was confirmed. LSM has been operating for more than 8 years on an actual hot strip mill. This paper describes the development details of LSM.
