Device for measuring shape of hot rolled steel coil

The invention relates to a device for measuring the shape of a hot rolled steel coil. The device comprises a distance measurer used for carrying out single-side scanning for a steel coil end portion on a stepping beam and acquiring a distance measurement value and distance measurement height in a high speed; a servo motor used for driving the distance measurer; and a host computer used for drafting a steel coil tower-shaped curve according to the acquired distance measurement value and the distance measurement height and determining the tower-shaped curve. The device is advantaged in that the coil shape of the hot rolled steel coil can be measured online. 本发明涉及种测量热轧钢卷卷形的装置，包括测距仪，用于对步进梁上的钢卷端部进行单侧扫描，高速采集测距值与测距高度；伺服电机，用于驱动所述测距仪；上位机，用于根据采集到的测距值与测距高度绘制钢卷塔形曲线，并对塔形曲线进行判定。本发明能够在线对热轧钢卷的卷形进行测量。
