摘　　要：研究不同退火制度下连续铸轧铝箔坯料组织与力学性能的变化。结果表明,随均匀化退火温度的升高和保温时间的延长,晶粒尺寸长大;在630℃×7 h退火制度下,铝箔坯料的各向异性基本消除,伸长率可达30%以上,有利于继续变形。在该工艺下生产的铝箔,成品率较高,平均针孔数较少。Microstructure and mechanical properties of continuous cast and rolled aluminum foil blank under different homogenizing annealing processes were studied. The results show that with annealing temperature and hold time increasing, the grain size grow up. At 630 ℃ - 7 h annealing process, the anisotropic of aluminum foil stock is almost eliminated, and elongation is above 30%, which is favor of continued deformation. The qualifiled product rate is relatively higher and average number of pinhole is less of aluminum foil prepared at the process, and 630 ℃- 7 h annealing process is the favorable.
