Embodiment Construction

[0068] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0069] Please refer to figure 1 , the invention provides a method for controlling the thickness stability of a cold-rolled 3104 alloy pop can aluminum strip, comprising the following steps:

[0070] Step S1: construct 3104 alloy pop can standard sample;

[0071] Step S11: select pop can product 3104 alloy coil;

[0072] In this embodiment, preferably, the composition mass fraction % is: Si: 0.13-0.28, Fe; 0.32-0.48Cu: 0.12-0.25; Mn: 0.78-0.95, Mg: 1.1-1.35%; Cr<0.02; Zn<0.09; Ti<0.02. The chemical composition of the collected standard sample should be close to the median value of the 3104 chemical composition, that is, the average value of the upper and lower limits of each chemical element.

[0073] Step S12: Sample specification and testing method: The window of the launch head of the thickness gauge is 50mm, and the standard sample size (length*w...

Abstract

The invention relates to a method for controlling the thickness stability of an aluminum strip of a cold-rolled 3104 alloy zip-top can. The method comprises the following steps that S1, a 3104 alloy zip-top can standard sample is constructed; S2, according to the obtained 3104 alloy zip-top can standard sample, a zip-top can 3104 alloy absorption coefficient of a thickness gauge and a strip temperature set value are calculated; and S3, online rolling thickness fluctuation visualization is established, and online rolling thickness fluctuation is monitored in real time. According to the method,operation visualization is achieved, defective products in the production process are reduced, the product quality is effectively guaranteed, the product quality is stable, and operation is easy and convenient.

Description

technical field [0001] The invention relates to the field of easy manufacture of cold-rolled 3104 alloys, and relates to a method for controlling the thickness stability of cold-rolled 3104 alloy pop-top can aluminum strips. Background technique [0002] At present, 3104 aluminum alloy is used in the production of cans at home and abroad, and the thickness of the hot-rolled billet is 2.0-2.7mm; the thickness difference control range is ±15-±25μm; the cold rolling mill is equipped with a six-roller CVC cold rolling mill from Germany SMS, and equipped with a German IMS thickness measurement Instrument, ABB electrical control system, cold rolling is produced in 3 passes, the reduction rate of each pass is 45-52%, the thickness of the finished product is controlled at 0.245-0.280mm; the thickness difference control range is ±3μm; the tensile strength is ≥290Mpa, and the yield Strength ≥ 265Mpa, elongation ≥ 5%, earing rate ≤ 3%; during the production process, it was found that t...
