本发明的背景 1.本发明的范围本发明介绍了制造深拉减薄罐体的连续铸造铝合金带材的制备工艺 2.原制造工艺近几年来,一些铝合金,例如美国铝业协会的3004铝合金已成功地用深拉减薄方法加工成两片式饮料罐。随着两片式铝罐用途不断扩大,对于制造罐体的铝合金薄板,不仅要求它具有良好的成形性能与强度性能,而且要求其加工制造的经济性。深拉减薄饮料罐用的典型铝合金薄板,是用直接水冷铸造的厚为508～628毫米的铸锭轧制的。将铸锭在510～607℃均匀化处理4～24小时,然后在204～482℃温度下经过
Background of the Invention 1. Scope of the Invention The present invention describes the preparation of a continuous cast aluminum alloy strip for making a deep-drawn can body 2. Raw Manufacturing Processes In recent years, some aluminum alloys, such as those of the American Aluminum Association 3004 aluminum alloy has been successfully deep drawn thinning method into two-piece beverage cans. With the expanding use of two-piece aluminum cans, aluminum alloy cans for can body manufacture require not only good formability and strength properties, but also economical processing and manufacturing. A typical aluminum alloy sheet for deep drawing and thinning beverage cans is rolled with an ingot of 508 to 628 mm in thickness, which is directly water-cooled. The ingot is homogenized at 510 to 607 ° C for 4 to 24 hours and then passed at a temperature of 204 to 482 ° C
