METHOD FOR DETECTING AND CLASSIFYING SURFACE DEFECTS ON CONTINUOUSLY CAST SLABS

摘要

1. A method for detecting and classifying surface defects on continuously cast products. 2.1 The invention relates to a method for detecting and clas sifying surface defects on continuously cast products, using topographical i nformation about the appearance of continuously cast surfaces, wherein defec ts and/or shortcomings are determined with positional accuracy, evaluated in terms of location and extension, and eliminated in accordance with the eval uation prior to further processing the product, or avoided through process o ptimization. The aim is a reliable defect evaluation process that is only in fact necessary. 2.2 The aim is achieved in that, one the one hand, the defe cts and/or shortcomings on the slab surface of the continuously cast prelimi nary product are detected and stored with positional accuracy and, on the ot her hand, a detection of defects and/or shortcomings on the finished product is performed, the information being stored with positional accuracy, and th at thereafter the information from the preliminary product is compared to th at obtained from the surface inspection of the finished product, and only th e information that has resulted, or can result, in defects on the finished p roduct is taken into account for an elimination of defects and/or shortcomin gs on the preliminary product.
