DEVICE FOR MEASURING SHAPE OF HOT-ROLLED STEEL SHEET

摘要

PURPOSE: A device for measuring the shape of a hot-rolled steel sheet is provided to measure the shape of a steel sheet regardless of width by changing the path of a laser beam. CONSTITUTION: A device for measuring the shape of a hot-rolled steel sheet includes a gauge room unit(100) consisting of two sensor boxes(110a,110b) and a processor unit(160) calculating the position of a hot-rolled steel sheet and the angle of a beam pass mirror, calculating shape data of the hot-rolled steel sheet by applying the signals detected by a camera unit to a determined formula, transmitting the shape data to a computer or directly controlling a rolling machine. The beam pass mirror is angle-adjustable. The path of the laser incident from the beam pass mirror is changed by a fixed mirror.
