多道次变形还表明,在高温轧制过程中,道次间隔的时间内,材料会发生回复和再结晶而软化,降低了轧制力,因此粗轧各道次间隔时间长一些。
Multi-pass deformation also shows that in high-temperature rolling process , the material will be softened as a result of the recovery and recrystallization , so the rolling force is reduced and the time interval of the passes of rough rolling should be longer .
