METHOD FOR CUTTING AND REMOVING DEPOSIT ON EDGE OF CUBOID METAL MATERIAL AND REMOVAL DEVICE

摘要

Adhesive matter remaining at the end of a cuboid metal material is reliably removed in a relatively short time while suppressing the decrease in yield rate of the metal material. Distances of the upper surface and the lower surface of a cuboid metal material (for example, a slab 10) from a reference position are measured using a distance measurement means (for example,.a laser distance meter 3) in the longitudinal direction of the slab 10 including the longitudinal end of the slab 10. On the basis of the measurement results, the state of remaining of adhesive matter 13 remaining on the upper and lower surfaces of the longitudinal end of the slab 10 is comprehended. On the basis of the state of remaining of adhesive matter 13, the amount and position of cutting by a cutting tool 2 is determined. Corner removing cutting is performed on the upper and lower surfaces of the longitudinal end of the slab 10 using the cutting tool 2 in accordance with the determined amount and position of cutting.
