Embodiment Construction
[0027] The present invention is described in further detail now in conjunction with accompanying drawing. These drawings are all simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, so they only show the configurations related to the present invention.
[0028] Such as figure 1 Shown, a kind of rolling method that is applied to ultra-long ultra-narrow aluminum strip, comprises the following steps:
[0029] (1) Design the rolling scheme for ultra-long and ultra-narrow aluminum strips. Ultra-long and ultra-narrow aluminum strips generally refer to aluminum strips with a length of more than 2000m and a width of 15-20mm. Rolling is designed for aluminum strips of different lengths and widths The plan can make the most suitable rolling plan according to the actual length and width of the aluminum strip;
[0030] (2) Weld two adjacent aluminum strips by welding equipment to form an aluminum strip of sufficient siz...

Abstract
The invention relates to a rolling method applied to an ultra-long and ultra-narrow aluminum strip. Through the rolling process of two times of primary rolling and finish rolling, the performance andsize of the aluminum strip are judged and detected after rolling of each time is finished, it is effectively guaranteed that the performance of the aluminum strip meets the preset requirement, the rolling process of the aluminum strip can be adjusted in time according to changing of the preset requirement, and the application range is wide; and before and after the rolling process, the aluminum strip is subjected to annealing treatment of two times under the protective atmosphere, and therefore forming and attachment of an oxidization layer on the surface of the aluminum strip can be effectively reduced while internal stress and surface defects of the aluminum strip are reduced.
Description
technical field [0001] The invention relates to an aluminum strip rolling method, in particular to a rolling method applied to an ultra-long and ultra-narrow aluminum strip. Background technique [0002] The ultra-long and ultra-narrow aluminum strips used for nuclear power cooling generally use ultra-long (above 2000m) ultra-narrow (15-20mm) pure aluminum strips (thickness 0.2-0.3mm), which have high dimensional accuracy, good performance strength, and comprehensive However, for the rolling method of this kind of ultra-long and ultra-narrow aluminum strip, in China, there is still no method of using this technology for aluminum strip rolling, and the existing aluminum strip rolling method can not be well Adapt to the rolling process of ultra-long ultra-narrow aluminum strip. Contents of the invention [0003] In order to overcome the deficiencies and defects in the prior art, the invention provides a rolling method applied to ultra-long and ultra-narrow aluminum strips. ...
