Abstract

The invention discloses a production method for a double-zero aluminum foil. The production method includes subjecting an aluminum-alloy molten mass to cast rolling to produce a cast rolling coil with the thickness of 6.5-8.0mm after degassing and deslagging, subjecting the cast rolling coil to first cold rolling to produce an aluminum coil with the thickness of 2.0-3.0mm, performing first heat treatment on the aluminum coil subjected to the first cold rolling at the temperature of 450-550 DEG C for 15-20 hours, subjecting the aluminum coil subjected to the first heat treatment to second cold rolling to produce an aluminum coil with the thickness of 0.6-0.8mm, and performing second heat treatment on the aluminum coil subjected to the second cold rolling at the temperature of 300-380 DEG C for 6-12 hours; subjecting the aluminum coil subjected to the second heat treatment to third cold rolling to produce an aluminum coil with the thickness of 0.05-0.1mm, heating the aluminum coil to the aluminum-foil recrystallization critical temperature of 250-310 DEG C, keeping the aluminum coil at the temperature for 5-10 hours, and subjecting an aluminum foil to fourth cold rolling to produce the double-zero aluminum foil with the thickness of 0.006-0.009mm. The double-zero aluminum foil produced by the production method has tensile strength of more than 95Mpa, ductility of more than 3.1%, small blank grain size, few surface stripes, few needle holes and stable quality.

Description

Technical field [0001] The present invention involves aluminum foil processing technology, which is specifically a production method of double zero aluminum foil. Background technique [0002] At present, dual -zero aluminum foil is mainly used in the field of packaging, such as soft packaging aluminum foil, cigarette aluminum foil, and cardboard aluminum foil.However, in addition to the softening bag on the surface of the aluminum foil, the cigarette card paper, aluminum foil and gold card paper need to be printed on the surface of the aluminum foil.With less, the color pulp you need to apply is less, and the effect after printing is good, and vice versa.If the surface of the aluminum foil is more and large, it is necessary to apply thicker color pulp to obtain a good printing effect, increasing the production cost of the enterprise. [0003] There are generally two types of billets in the current two -zero aluminum foil blank in the current industry, one is casting rolling bill...
