A method for reproduce the oxide scale in hot rolling is proposed using the vacuum hot rolling mill. This method is possible to control of scale thickness and chemical composition in actual hot rolling process.From results, it is possible to clear the deformation behavior of state generated the oxide scale, oxide scale thickness is thick enough amount of Fe 2 O 3 billets. The oxide scale thickness is proportional to the amount of Fe 2 O 3 . Some cracks appeared before the roll bite during
