Sumitomo Metal Ind. Ltd. has succeeded in developing a new type of shape meter to measure the flatness of hot strips at the exit of a hot finishing mill. The meter consists of an Ar-ion laser, three optical scanning mirrors, a high speed TV camera, and an image processor. It is based on the light section method. Three laser beams scan the width of the strips. The TV camera takes the projected laser beam image on the strip. The image processor calculates the height and the elongation index (flatness) of the strip. Because the elongation indexes are calculated using three projected beams, the measuring error caused by the strip's flutter is canceled. The accuracy of height measurement was confirmed to be ±1 mm. The flatness measured by the shape meter agreed with the results of visual observation by mill operators. It can be used even in hot, steamy and dusty atmospheres. These meters have been in practical use at Kashima Steel Works and Wakayama Steel Works since January 1986. They have been contributing to the improvement in the quality of hot strip coils.
