Four-pass aluminum foil rolling process

Abstract

The invention relates to a four-pass aluminum foil rolling process, and belongs to the technical field of aluminum foil rolling process. The process comprises the following steps: 1, selecting materials; 2, performing first-pass rolling; 3, performing second-pass rolling; 4, performing third-pass rolling; 5, folding; and 6, performing fourth-pass rolling. The four-pass aluminum foil rolling process has a simple process flow, reduces the loss of defective products caused by one-pass acceleration and deceleration by increasing the rolling reduction of each rolling pass, and simultaneously guarantees that the finished product has no defect such as twill, herringbone, hot blast and the like; the loss of defective products caused by each-pass acceleration and deceleration is about 1 percent, the loss of one-pass lap changing time is also saved, and the lost time of each lap changing is about 10 minutes; therefore, the rolling speed is improved, and the overall improved speed is about 13 percent.

Description

technical field [0001] The invention relates to a four-pass rolling process of aluminum foil, and belongs to the technical field of aluminum foil rolling process. Background technique [0002] At present, all domestic manufacturers can basically produce 0.006mm aluminum foil stably, and the reduction rate is generally controlled below 53%. The surface quality of each rolling pass is good, the speed is appropriate, and the surface quality is good. Generally, surface defects such as twill, herringbone, and hot drum are prone to appear, which will have a great impact on the composite quality of downstream products. Contents of the invention [0003] The purpose of the present invention is to solve the shortcomings of the above-mentioned prior art, and provide a simple and convenient process flow. By increasing the reduction amount of each pass, the reduction of one pass is reduced, thereby greatly improving the production efficiency and reducing one pass. The four-pass alumi...
