Embodiment Construction

[0032] The present invention will be described in further detail below in conjunction with specific embodiments.

[0033] Foil rolling 4-pass foil rolling preparation process of the present invention: 0.21mm-0.082mm-0.032mm-0.0128mm-coil 2*0.0128*2*0.005mm.

[0034] The above average reduction in each pass is about 60%, the foil rolling speed is 700-800m / min for the first pass, 1000-1100m / min for the second pass, 1100-1200m / min for the third pass, and 1100-1200m / min for the third pass. The four passes are 600-700m / min. The thickness of the aluminum foil at the first entrance is 0.21mm, and the alloy grade is AA1235.

[0035] The 4-pass rolling method of 0.005mm thick aluminum foil comprises the following steps:

[0036] 1), base material

[0037] A billet with a thickness of 0.21m is used, and the alloy is AA1235;

[0038] 2), the first pass of foil rolling

[0039] The base material with a thickness of 0.21mm enters the 4-roller rolling of the rough rolling mill (it is a...

Abstract

The invention relates to foil rolling preparation of 0.005 mm ultra-thin aluminum foil, in particular to a four-pass rolling method for aluminum foil with the thickness being 0.005 mm. As for a foil rolling preparation method, by adjusting process oils of a foil rolling mill and optimizing foil rolling pass distribution, original five-pass foil rolling is reduced to four-pass foil rolling, so as to obtain the aluminum foil with the thickness being 0.005 mm. According to the four-pass rolling method for the aluminum foil with the thickness being 0.005 mm, the number of foil rolling passes is decreased, and the overall efficiency of foil rolling is improved by 15% or above.

Description

technical field [0001] The invention relates to the rolling preparation of 0.005mm ultra-thin aluminum foil, in particular to a 4-pass rolling method of 0.005mm thick aluminum foil. Background technique [0002] At present, the application of aluminum foil is becoming more and more extensive, and China has become a major producer of aluminum foil. With the cost control of aluminum foil manufacturers and changes in the international environment, the demand for ultra-thin aluminum foil continues to increase, and the current production of ultra-thin aluminum foil in foil 5-pass rolling is used during rolling, and the efficiency has been difficult to improve; or 0.005mm aluminum foil cannot be obtained by other four-pass production methods. [0003] For example, the five-pass foil rolling preparation process in patent CN2011102140667.8: [0004] 0.3mm-0.14mm-0.07mm-0.038mm-0.013mm-coil 2*0.013mm-2*0.005mm. [0005] The efficiency of the above 5-pass foil rolling is low, and th...
