提出了一种利用真空热轧机实现热轧氧化铁皮再生的方法。该方法可以在实际热轧过程中控制氧化皮厚度和化学成分，从结果可以明确氧化皮生成状态下的变形行为，氧化皮厚度足够厚的Fe2O3坯料量。氧化皮厚度与Fe2O3的量成正比。氧化铁皮在轧制过程中，在咬入前出现裂纹.然后，在轧辊出口的轧辊咬入处发生剥落或破坏。
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 Fe2O3billets. The oxide scale thickness is proportional to the amount of Fe2O3. Some cracks appeared before the roll bite during rolling the oxide scale. Then, peeling or destruction occurred in roll bite for roll exit.
