将厚度为12.2毫米的305毫米宽×914毫米长的铸造铝带板置于氮气炉中,迅速加热到要求温度,在590～610℃再结晶温度下保持10～40小时。然后将带板从炉中取出,向带板上吹冷的压缩空气,冷至室温。在这一系列操作中采用的均匀化条件归纳于表4。将冷却了的带板经过多道次轧制减薄66％～75％,其厚度为4.06～3.05毫米。
A 305 mm wide by 914 mm long cast aluminum strip with a thickness of 12.2 mm was placed in a nitrogen furnace and rapidly heated to the desired temperature for 10-40 hours at a recrystallization temperature of 590-610 ° C. The strip is then removed from the furnace and the compressed air is blown cold on the strip and cooled to room temperature. Homogenization conditions used in this series of operations are summarized in Table 4. The cooled strip is reduced in thickness by 66% to 75% through multiple pass rolling with a thickness of 4.06 to 3.05 mm.
