A METHOD FOR THE DETECTION AND CLASSIFICATION OF SURFACE DEFECTS ON CONTINOUSLY CAST PRODUCTS

摘要

The invention is directed to a method for the detection and classification of surface defects on continuously cast products using topographical information about the appearance of continuously cast surfaces, wherein defects and/or flaws are determined with respect to their exact position, evaluated with respect to their location and dimensions, and eliminated in accordance with the evaluation prior to further machining of the product, or are prevented by optimizing the process. The aim is a more reliable and only strictly necessary evaluation of defects. This aim is achieved in that, on the one hand, the defects and/or flaws on the slab surface of the continuously cast preliminary product are detected and are stored with respect to their exact position and, on the other hand, a detection of defects and/or flaws on the finished product is carried out and stored with respect to their exact position, and in that the information from the preliminary product is then compared with the information from the surface inspection on the finished product, and only the information which has led to, or can lead to, defects on the finished product is taken into account for the elimination of defects and/or flaws on the preliminary product.
