Laser Systems for Automationand Quality Control in Steel MillsLAP CroptimizerDimension-measurement and Crop ShearsOptimizationThis flexible and complex measurement system has been designedfor precise measurement of the geometry of plates and strips in hotand cold rolling mills. The system provides: Width and shape (sables, necking) Over-all length Flatness, waviness Crop shape at front and rear ThicknessWidth is measured through two lateral Laser triangulation sensorswith high resolution. Special Laser optics (patented) overcome theproblem of vertical material movement. The simple installation ofthe sensors beside the roller table (lateral to the transportationdirection) provides several benefits: Needs no heavy support constructions Provides easy access to the devices Reduces thermal loadThe high rate of measured values of each sensor up to 500 Hzshows a precise recording of width and is controlled by the LMS Shapemeter, a system consistingof 7 to 11 self-contained distance gauges, which incorporate lasertriangulation as the principle of operation.
Width Measurement The width measurement system consists of two LMS 6024 sensors and is designed for use in – Continuous casting of slabs, blooms and billets
