1100 coating aluminum plate strip rolling technology

Abstract

The invention relates to a 1100 coating aluminum plate strip rolling technology in the field of aluminum plate strip machining. The technology includes the steps that 7.0-3.9-1.8-0.85 three passes of rolling are conducted on a plate strip through a rolling machine; then trimming is conducted to 2010 mm; then 0.85-0.45-0.27-0.18 three passes of rolling are conducted; and finally, after a finished product is annealed, the finished product is slit to reach the finished product width through a slitting machine, and detecting and packaging are conducted. According to the technology, the rolling passes can be effectively reduced, and therefore the production period is shortened correspondingly, and the yield is increased; and in addition, when the technology is used in cooperation with an imported rolling machine, the capacity superiority of the imported rolling machine can be shown.

[0001] 【Technical field】 [0002] The invention relates to the field of processing aluminum strips, in particular to a rolling process for rolling 1100 coated aluminum strips. [0003] 【Background technique】 [0004] It is well known that when rolling aluminum alloy strips, especially some high-strength aluminum alloy strips, affected by factors such as material deformation, heat generation and uneven lubrication, it is easy to cause lateral deviation of the aluminum strips during the rolling process. shift, resulting in defects that affect product quality such as coiling sticking; in long-term practical applications, it is found that the existing process uses seven-pass rolling based on shape control, and the 1100 coated aluminum strip For example, it is first rolled through the rolling mill in four passes of 7.0-4.4-2.2-1.2-0.7, then trimmed to 2010mm, and then rolled in three passes of 0.7-0.42-0.26-0.18, and finally After the finished product is annealed, it is cut to the ...

[0004] It is well known that when rolling aluminum alloy strips, especially some high-strength aluminum alloy strips, affected by factors such as material deformation, heat generation and uneven lubrication, it is easy to cause lateral deviation of the aluminum strips during the rolling process. shift, resulting in defects that affect product quality such as coiling sticking; in long-term practical applications, it is found that the existing process uses seven-pass rolling based on shape control, and the 1100 coated aluminum strip For example, it is first rolled through the rolling mill in four passes of 7.0-4.4-2.2-1.2-0.7, then trimmed to 2010mm, and then rolled in three passes of 0.7-0.42-0.26-0.18, and finally After the finished product is annealed, it is cut to the width of the finished product by a slitting machine for inspection and packaging. The rolling passes are relatively many, and when it is used in conjunction with an imported rolling mill, it cannot take advantage of the ability of the imported rolling mill. In actual operation, due to each increase One pass will reduce the finished product rate accordingly, increase its production cost, and consume more kinetic energy at the same time, directly resulting in an increase of about 200 yuan per ton cost. Therefore, the existing process not only has a relatively long production cycle, but also lowers the production cost Relatively high, ultimately leading to the fact that the traditional rolled 1100 coated aluminum strip cannot take advantage of the market competition in terms of delivery cycle and yield
