example 1

[0036] The production specification thickness*width*length is 0.0063mm*1420mm*48200m and the order is 52 volumes in total, of which 26 volumes are produced using the elaboration method of the present invention, and the other 26 volumes are not lengthened.

[0040] Comparison table of thermal drum conditions during packaging

[0041]

[0042] Through the comparison of the lengthened and non-lengthened aluminum coils of Example 1, the aluminum foil produced by the method of the invention has a lower heat drum generation ratio of 81.2% and a final scrap rate of 5.9% lower.

example 2

[0044] The production specification thickness*width*length is 0.006mm*1240mm*36000m and the order is 60 rolls in total, of which 28 rolls are produced by using the elaboration method of the present invention, and the other 32 rolls are produced by using normal parameters to lengthen the production.

[0046] Comparison table of thermal drum conditions during packaging

[0047]

[0048] The comparison between the normal parameters of Example 2 and the lengthening of the parameters of this method proves that the aluminum foil produced by the method of the invention has a 79.5% lower heat drum generation ratio and a 3.2% lower waste rate eventually.

example 3

[0050] The production specification thickness*width*length is 0.006mm*1040mm*12200m and the order is 126 rolls in total, 40 rolls of which are produced using the elaboration method of the present invention, 40 rolls are produced using normal parameters for lengthening, and the other 46 rolls are not lengthened.

[0052]

[0053] Comparison table of thermal drum conditions during packaging

[0054]

[0055] The comparison of Example 3 proves that the aluminum foil produced by the method of this invention has the lowest rate of occurrence of hot drums and the generation of final waste.

Abstract

The invention belongs to the field of aluminum material processing, and specifically relates to a method for improving double-zero aluminum foil annealing heat drums. During the slitting process of aluminum foil rolls, the flattening pressure, support pressure and tension of the slitting machine are lowered. Continue to wrap the extended aluminum foil on the aluminum foil roll, so that wrinkles will be generated when the extended aluminum foil is wound. This method has low investment and remarkable effect. Through special parameters, the wrinkles and density of the outer ring of the slitting roll are greatly reduced, which is equivalent to forming a heat isolation layer on the outer ring of the aluminum foil roll, and can significantly reduce the generation of annealing heat drum.

Description

technical field [0001] The invention belongs to the field of aluminum material processing, and in particular relates to a method for improving a double-zero aluminum foil annealing heat drum. Background technique [0002] With the advancement of China's industrial foundation and technology, China has become a big and powerful country in aluminum processing. Aluminum foil is also widely used in food packaging, electric power, heat insulation, communication, batteries and other industries. [0003] The basic processing process of aluminum foil is rough rolling, coiling, finishing rolling, slitting, annealing, and packaging. Aluminum foil, especially double-zero aluminum foil, tends to have one or more stripes on the foil surface of the aluminum foil during the annealing process. The industry refers to this phenomenon as annealing heat drum. The downstream customers of the aluminum foil with an annealing heat drum cannot use it, so when the annealing heat drum appears, it need...
