Reproduction and Deformation Characteristics of Oxide Scale in Hot Rolling Using Vacuum Rolling Mill


Article Preview

There is fear that the oxide scale formed in hot rolling causes adverse effects for surface properties of final product. In hot rolling, the sheet surface is occurred reoxidation after descaling. Therefore, the oxide scale is rolled together, and causes the surface defect. In this study, the method for reproducing the oxide scale in hot rolling is proposed by a vacuum hot rolling mill, named the scale transfer method, and focused on the deformation of the oxide scale itself. As the results, it’s possible to reproduce the oxide scale in the actual hot rolling process. It showed that causes the new surface defect for invading the oxide scale in the sheet surface during roll bite.
