轧制金属板时,采用异步轧制与等速轧制的比轧制负荷可大幅度降低。由于轧制负荷的减少,可以增大压下率或减少轧制道次数,并且可以轧制薄而硬的材料。但是,由于异步轧制是上下非对称轧制,往往因轧制条件不同而使金属板产生翘曲和上下表面性状不同。本文是用一台异步轧机对同一材 When rolling sheet metal, the use of asynchronous rolling and constant speed rolling than the rolling load can be significantly reduced. Due to the reduction of the rolling load, the reduction rate can be increased or the number of passes can be reduced, and the thin, hard material can be rolled. However, asynchrony rolling is asymmetric rolling up and down, often due to different rolling conditions of the metal plate warpage and the upper and lower surface properties vary.
