背景技术

现有技术存在的问题有:铝材加热至690—820℃,处于完全熔化状态,再静置5—15min,浇入注嘴中烧注冷去成半固态,再和铜板轧制复合。静置等待时间长,生产效率低。且先熔化再冷却制造半固态的方法对能量浪费较多,不坏保,因此,还需要开发新型的制备方法。

铜铝复合金属板带的制备工艺,该工艺包括以下步骤:
第一步,预处理加热:铜带复合前预热,去除氧化层和油脂,提升铜带表面活化能,保证复合过程金属分子间结合力;
第二步,碱洗脱脂:将铜带进行碱洗脱脂,并用钢刷打磨表面,去除铜带表面氧化层,并加铜带预加热至230—400℃;
第三步,升温加热:将铝料加热,在线调节温度至620—670℃,得到处于半熔化半固体状态的铝料;
第四步,无氧铸轧:在保护气环境中将半熔态的铝料与铜带打磨过的表面接触,进行无氧连续铸轧,得到铜铝复合板带坯料;
第五步,二次精轧:对铜铝复合板带坯料进行二次精轧,校准板厚宽度,制得的铜铝复合板带厚度为2.5—15mm,其中铜层厚度为0.5~4mm,铜和铝的结合强度不低于铝的强度。
作为优选,所述第四步中;保护气环境中的气体为氮气或氨气。
作为优选,所述第四步中;轧制速度0.3—2.0m/s,轧制压力5*10^6N—14*10^6N,张力为3*10^6N—9x10^6N。
作为优选,所述第二步中,加铜带预加热至280℃,第二步中在线调节温度至640℃。
作为优选,所述第二步中加铜带预加热至230℃,第三步中,在线调节温度至650℃。
作为优选,所述第二步中加铜带预加热至400℃,第三步,中在线调节温度至660℃。
本发明所产生的有益效果是:
1、省去冷却时间和冷却过程的热量损失,提高生产效率和降低能源损耗。
2、无氧环境中轧制可防止轧制过程中,界面氧化,影响界面强度。发明要求参数范围内的轧制压力、轧制速度和收卷张力可保证界面复合结合强度大于铝材强度,界面剪切时只在铝材断裂,不会发生界面分离。
