Abstract

This paper introduces the method, Predictive Repeating Defect Detection, which developed by ABB Surface Imaging Systems. The method enables the surface inspection system to detect very weak cyclic defect as they start to occur in production of flat rolled products. System can be used in hot rolling, cold rolling and processing lines; for carbon steel, stainless steel, aluminum and copper. This paper also introduces the implementation and results of the function to Outokumpu Tornio hot rolling mill.
