摘要：AbstractThis paper deals with the estimation of the contour of hot-rolled steel plates and of quality parameters characterizing the trimmed edge. Suboptimal process parameters can cause camber or a saw-tooth shaped contour and imperfections on the trimmed edges. Quantitative measures of these imperfections enable a seamless quality control and can be used as input quantities for data-based or control engineering applications. The presented method utilizes measurements from 2D-laser sensors installed at the side of the production line after a trimming shear. A model-based optimization algorithm estimates the contour and a possible rotation of the plate. Signal processing and sensor fusion are employed to estimate additional quality parameters. Validation with measurement data from a rolling mill demonstrates the high accuracy of the proposed method. The camber is estimated with an accuracy lower than ±0.04 mm/m, which reveals that the proposed method is more accurate than existing solutions for camber estimation.
