Rolling technology of 3104/3004 lamp holder material

Abstract

The invention relates to a rolling technology of a 3104 / 3004 lamp holder material, and belongs to the field of aluminum sheet strip machining. The technology comprises the steps that 3.0-1.3-0.65 two-pass rolling is conducted on a sheet strip; after trimming is conducted, 0.65-0.36-0.23 two-pass rolling is conducted; after being annealed, the finished product is slit to achieve the width of the finished product through a slitting machine, and then detecting and packaging are conducted. According to the technology, due to the fact that the rolling passes can be effectively decreased, the production cycle is correspondingly shortened, the finished product rate is increased, and the capacity advantage of an imported rolling machine can be shown when the rolling technology is used with the imported rolling machine in a matched mode.

[0001] 【Technical field】 [0002] The invention relates to the field of processing aluminum strips, in particular to a rolling process for rolling 3104 / 3004 lamp cap materials. [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. shifting, resulting in defects that affect product quality such as coiling sticking; in long-term practical applications, it is found that the existing process uses five-pass rolling based on plate shape control, and the 3104 / 3004 lamp cap material For example, it is first rolled through the rolling mill for three passes of 3.0-1.5-0.8-0.5, and then rolled for two passes of 0.5-0.32-0.23 after edge trimming, and finally passed through after annealing of the finished product.

[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. shifting, resulting in defects that affect product quality such as coiling sticking; in long-term practical applications, it is found that the existing process uses five-pass rolling based on plate shape control, and the 3104 / 3004 lamp cap material For example, it is first rolled through the rolling mill for three passes of 3.0-1.5-0.8-0.5, and then rolled for two passes of 0.5-0.32-0.23 after edge trimming, and finally passed through after annealing of the finished product. The slitter is cut to the width of the finished product for inspection and packaging. Its rolling passes are relatively large, and when it is used in conjunction with imported rolling mills, it cannot take advantage of the capabilities of imported rolling mills. It will reduce the finished product rate accordingly, increase its production cost, and consume more kinetic energy at the same time, directly leading to an increase of about 200 yuan per ton cost. Therefore, the existing process not only has a relatively long production cycle, but also relatively high production costs. In the end, the traditional rolling 3104 / 3004 lamp head material cannot take advantage of the market competition in terms of delivery cycle and yield
