世界上的原铝大约有一半是用来加工成扁平制品,例如厚板、薄板、带材及箔材。轧制产品的制造过程需经过两个加工步骤,第一步是使液体铝变为宽的带卷(其厚度在2～10毫米之间,轧制坯料)。轧制坯料的传统生产方法要求好几个步骤:如铸造扁铸锭、锯切、铣去表面缺陷、均热及最终热轧(图1)。因此,生产轧制坯料时劳动强度大、能量和资金消耗多。除 About half of the world’s primary aluminum is processed into flat products such as slabs, sheets, strips and foils. The manufacturing process of a rolled product takes two processing steps. The first step is to change the liquid aluminum into a wide coil (thickness between 2 and 10 mm, rolled stock). Traditional methods of producing rolled stock require several steps: casting of flat ingots, sawing, surface delamination, soaking and final hot rolling (Figure 1). Therefore, the production of rolled billet labor-intensive, energy and capital consumption. except
