ABSTRACT:
A surface of a long flat product is observed in a production process by way of a surface inspection system. The entire surface is plotted, on the basis of the observation data, as a surface map with established surface characteristics in the, form of surface data and the surface characteristics are classified according to the different types and/or sizes and/or frequency and registered in the surface map according to their position. Production data and product data are jointly fed to a data processing unit in which they are analyzed to determine correlations between them. Rules dealing with the dependence of product data upon given production data are determined so that process parameters can be regulated in line with the rules thus determined to obtain a desired quality. Interrelationships can be recognized between process parameters and the emergence of surface errors, for instance in continuous casting and rolling facilities for steel sheets.
