摘　　要：铝合金因质轻美观、导热、导电性好、耐腐蚀性好、耐低温性好、易于成型加工和表面处理、易于回收再利用、地球存储量大等优点,被广泛应用于建筑装饰、金属包装、交通运输、电气家电、航空航天等领域。但各方面都对于表面、板形、尺寸精度要求极高,故对设备及人员操作要求都很严,需要在各个环节严格把控。特别对于表面质量,因为工序较多,材料较软,要求又高,严重程度无法定量,所以表面质量是最不易判定和控制的。建筑装饰带材最后要经过拉矫、退火等关键工序,对最终表面和性能有重要的影响。Aluminum alloy is widely used in architectural decoration,metal packaging,transportation,electrical home appliances,aerospace and other fields due to the advantages of light and beautiful quality,good heat conductivity,good electrical conductivity,good corrosion resistance,good low temperature resistance,easy molding,processing and surface treatment,easy recycling and reuse,large earth storage volume and so on.However,all aspects of the surface,flatness,size precision requirements are very high,so the equipment and personnel operation requirements are very strict,the need to be strictly controlled in each link.Especially for the surface quality,because the process is more,soft materials,high requirements,the severity can not be quantitative,so the surface quality is the most difficult to determine and control.The architectural decoration belt material should finally go through the key processes such as straightening and annealing,which has an important impact on the final surface and performance.
