WebThe Standard explains that discontinuities could include: rolled-in scale; pitting; indenta- tions and roll marks (depressions and protuberances due to roll wear); scratches and grooves; spills and slivers (elongated flake-like discontinuities); blisters; sand patches; cracks; shells (overlapping material with non-metallic inclusions); and seams … WebA rolled-in scale defect occurs when mill scale is rolled into the metal during the rolling process. Mill scale is the flaky mixture of iron oxides that form on the surface of hot steel. Rolled-In Scale Ask Us Have a question? Send us a message New Terms Scrap Credit … rainbow city kia dealer
Correlation between the loading of work-rolls, banding and rolled-in scale
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. WebDec 13, 2016 · Surface quality and downstream processability of hot rolled strip depend on tertiary scale thickness and composition at all process stages, from secondary descaling to the cold coil. TGA oxidation experiments provided the basis for quantitative modelling of scale growth during finishing hot rolling of low carbon steels (with or without Si or P).
