国外轧铝的发展较早,1924年日本就开始轧铝,直到二次世界大战期间,才从家具用的板材生产上增加了飞机用板材的生产。二次世界大战之后,特别在1955年以后,轧制范围扩大了,板材的主要用途是:装饰、建筑、运输、包装、家具及电气等方面。近几年来,多量用在制容器、印刷和冷藏等方面。目前,国外随着轧制板材生产量的增大,对铝板表面质量也提出了严格的要求,因而促进铝轧制技术的不断发展。从轧制设备来看,由二重轧机或四重可逆式轧机发展到四重串连轧机机列。
Rolling aluminum abroad developed earlier, in 1924 Japan began rolling aluminum, until the Second World War, only from the furniture used in the production of sheet metal aircraft increased production. After World War II, especially after 1955, the scope of rolling has been expanded. The main uses of the sheet are: decoration, construction, transportation, packaging, furniture and electrical. In recent years, a large number of used containers, printing and refrigeration and so on. At present, with the increase in the production of rolled sheet abroad, the quality of the aluminum sheet is also put forward strict requirements, thus promoting the continuous development of aluminum rolling technology. From the rolling equipment point of view, by the double-mill or quadruple reversible mill developed to quadruple tandem mill series.
