Annealing technology for 8006-alloy double zero aluminum foil

Abstract

The invention relates to the technical field of double zero aluminum foil annealing and discloses an annealing technology for 8006-alloy double zero aluminum foil. The annealing technology for the 8006-alloy double zero aluminum foil comprises the following specific steps that firstly, outside-furnace standing is conducted; secondly, inside-furnace pretreatment is conducted; thirdly, uniform annealing is conducted; fourthly, intermediate temperature annealing is conducted; fifthly, low temperature annealing is conducted; sixthly, inside-furnace cooling is conducted; and seventhly, the aluminumfoil is discharged from the furnace. By means of the annealing technology for the 8006-alloy double zero aluminum foil, the number of hot-bulged rolls and the hot bulging depth can be lowered; the scrapping amount generated by hot bulging is lowered; and the production cost is lowered.

Description

technical field [0001] The invention relates to the technical field of double-zero aluminum foil annealing, in particular to an annealing process of 8006 alloy double-zero aluminum foil. Background technique [0002] At present, domestic production of 8006 alloy double-zero foil products is less, and foreign demand is gradually increasing. Using 8006 alloy to produce double-zero foil has very good advantages, specifically: 1) 8006 alloy contains Mn element, which is especially beneficial to the corrosion resistance of aluminum foil performance. 2) According to the test results of air-conditioning aluminum foil and thinned beer label aluminum foil, 8006 alloy has better mechanical properties than 8011, 8079, and 1235 alloys. 3) The research results show that 8006 alloy has good surface quality and extremely low number of pinholes. 4) The rolling process performance of 8006 alloy is good, and it is not easy to produce edge cracking defects. [0003] At present, more and mor...

AI Technical Summary

Problems solved by technology

[0006] Aiming at the deficiencies of the prior art, the present invention provides an annealing process for 8006 alloy double-zero aluminum foil, which has the advantages of reducing the number and depth of hot drum rolls, reducing the amount of scrap generated by hot drums, and reducing production costs. It solves the problem that the aluminum foil currently used in the market cannot be flattened due to the double-zero aluminum foil roll formed by the hot drum during the user's compound use, and there are still traces of the hot drum after compounding, which affects the surface quality of the composite material and the user's experience.
