摘　　要：采用实验拉力机和金相显微镜对铸轧法生产的3003铝合金幕墙板的力学性能和晶粒组织进行了研究,对3003铝合金大卷中间退火工艺进行了优化。结果表明:3003铝合金大卷进行中间退火时,将工艺设为530℃×9 h+390℃×3.5 h+随炉冷却3.5 h较为合理,能够有效控制晶粒长大,同时使板材的晶粒分布较为均匀,可有效提高板带材表面质量,提高生产效率、节约能耗。The experimental tensile machine and metal microscope studied the mechanical properties and grain structure of the 3003 aluminum alloy curtain plate and optimized the intermediate annealing process of 3003 aluminum alloy.The results show that during intermediate annealing of 3003 aluminum alloy coil,it is reasonable to set 530℃×9 h+390℃×3.5 h+to cool 3.5 h with the furnace,effectively control grain growth and make plate grain distribution,effectively improve the surface quality of plate strip,improve production efficiency and save energy consumption.
