摘　　要：以试验为基础,对同一罩式炉炉台冷轧08A l钢带的退火周期进行多点温度测量。分析退火温度对再结晶的影响。得出各阶段钢卷温度分布规律:钢卷退火时卷心和外圈为热点,卷中部为冷点,为了保证钢带良好的冲压性能,要适当调整罩式炉的加热速度和保温时间。Based on the experiment,multipoint temperatures examination with the same furnace along the 08Al roll steel strip during bell-type furnace annealing were carried out.The effect of temperature on recystallization was studied.The roll core and out are hot points,but middle part is colder point.And heating speed and holding time of bell-type annealing furnace should be adjusted in order to keep good deep-stamping performance of steel strip.
