SIMULTANEOUS MEASUREMENT SYSTEM FOR ASYMMETRIC UPPER AND LOWER AMOUNT OF SIDE SURFACE OF SLAB AND WARPING

摘要

Disclosed is a system simultaneously measuring the longitudinal asymmetric amount and the warping of the side surface of a slab. The system according to the present invention comprises a projector (100) irradiating a linear laser beam to the side surface of the slab so that the warping degree of the front end of the slab can be measured by measuring the longitudinal asymmetric amount of the side surface of the slab and the height (y) of the front end of the slab; a camera (200) photographing the flexure of the side surface of the slab by the shape of the laser beam irradiated from the projector; and a speedometer (300) measuring the moving distance (x) of the front end through the moving speed of the slab.
