Abstract
Official abstract text for this publication.
Provided are a steel-shape measurement device and a steel-shape correction device. The steel-shape measurement device measures a distance to a detection spot group on a to-be-scanned surface of a steel product with a laser rangefinder 5 A that measures the distance through scanning of a steel product S with a laser beam emitted from one laser light source 11 and redirected with a galvanometer mirror 13, and measures a shape of the steel product from obtained measured-distance data. The steel-shape measurement device includes an object having a 45°-0° diffuse reflectance of equal to or lower than 10% as a laser-beam absorber 8 at least one portion within an irradiation range irradiated with a regular-reflected laser beam from a to-be-scanned surface of the steel product.
First claim
Opening claim text (preview).
The invention claimed is: 1. A steel-shape measurement device that measures a distance to a detection spot group on a to-be-scanned surface of a steel product with a laser rangefinder that measures the distance through scanning of the steel product with a laser beam redirected with a galvanometer mirror after emitted from one laser light source, and measures a shape of the steel product from obtained measured-distance data, the steel-shape measurement device comprising: an object having a 45°-0° diffuse reflectance of equal to or lower than 10% as a laser-beam absorber at least at one location within an irradiation range irradiated with a regularly-reflected laser beam from the to-be-scanned surface of the steel product. 2. A steel-shape correction device including a press and transport devices that are disposed on an entry side and an exit side of the press to transport a steel product, the press including a pressing ram, the steel-shape correction device comprising: the steel-shape measurement device according to claim 1 on the entry side and the exit side of the press. 3. The steel-shape correction device according to claim 2 , wherein a location at which the laser-beam absorber of the steel-shape measurement device is disposed includes a location on a surface of outer surfaces of the press within the irradiation range.
