摘　　要：热轧开轧及终轧温度的高低对纯铝系铝卷的组织优劣有重要影响。热轧开轧温度处于420℃以下时,轧件在整个热轧过程中的温度较低,从而导致轧件在热轧过程中发生的再结晶程度低下。如果此时的终轧温度低于280℃,则很容易导致热轧卷产生粗大的晶粒和条状延伸组织。这些组织会遗传到冷轧,当冷轧道次压下量比较小时易出现白色的轧制色差带。The initial and final rolling temperature of hot rolling has an important effect on the microstructure of pure aluminum coil.When the initial rolling temperature of the hot rolling is below 420 ℃, the temperature of the rolled parts in the whole hot rolling process is low, which leads to the low recrystallization degree of the rolled parts in the hot rolling process. If the final rolling temperature is lower than 280 ℃, it is easy to lead to the coarse grain and band extension structure of the hot rolled coil, which is inherited to the cold rolling, and white rolling color difference band is easy to appear when cold rolling pass reduction is relatively small.
