目前,由古比雪夫冶金厂和德米特罗夫铝罐头带材试验厂生产的AMr2合金带材已广泛用于鱼、肉罐头罐的生产。这种带材的拉伸系数并不大(低于0.5)。然而对于果品蔬菜罐头是采用拉伸系数为0.6的№4A罐和拉伸系数为1.0的№5A罐。这就是说,对用于深拉的铝带材的铝合金带材生产工艺流程必须作预先分析。低合金化的铝合金带材的性能,取决于合金的化学 At present, the AMr2 alloy strip produced by the Guibisheff Metallurgical Plant and the Dmitrov Aluminum Canned Strip Test Plant is widely used in the production of canned fish and canned meat. The tensile coefficient of this tape is not large (less than 0.5). However, for canned vegetables, № 4A cans with a draw ratio of 0.6 and № 5A cans with a draw ratio of 1.0 were used. This means that the aluminum alloy strip production process for deep drawing of aluminum strip must be pre-analyzed. The performance of a low-alloyed aluminum alloy strip depends on the chemistry of the alloy
