Web'Rolled in scale' (RIS) and 'Rolled in Scum' (RISc) are two superficial surface defects on cold rolled and annealed steel sheets which affect the aesthetics of surface and thereby that of the end-product. Both the defects are believed to be originating from distinctly different sources having different mechanisms of formation. WebOriginally rolled in scale of Ni containing high carbon steel is notorious, difficult to remove, but after all new FSB with higher descaling pressure and short distance between nozzles and sheet bar surface solved the problem. We could produce Ni containing high carbon strip without any rolled in scale after the installation of new FSB.
