Abstract

The invention discloses a production process for rolling a light gauge aluminum foil, which comprises the following steps of: performing rough rolling, wherein the reduction per pass of the rough rolling is 0.3mm to 0.14mm to 0.07mm to 0.038mm; performing intermediate rolling, wherein the reduction per pass of the intermediate rolling is 0.038mm to 0.013mm; performing double rolling; performing intermediate annealing; cleaning a stock, namely performing surface cleaning on the aluminum foil stock by using rolling oil at a finish rolling inlet; performing finish rolling, wherein the reduction per pass of the finish rolling is 0.013mm to 0.005mm; slitting; annealing a semi-finished product; and packaging and warehousing. By adding the intermediate annealing and rolling oil cleaning processes for the aluminum foil, the mechanical property of the aluminum foil is improved while the thickness of the aluminum foil is reduced, and the breakage condition and a pinhole number in the rolling process are reduced.

Description

technical field

[0001] The invention relates to the field of aluminum foil production technology, in particular to a production technology for preparing double-zero aluminum foil by casting and rolling. Background technique

[0002] Aluminum foil is a thin sheet made of metal aluminum, which is often used as hot stamping materials, capacitors, packaging materials, etc. Due to the soft texture, good ductility and silvery white luster of aluminum, if the calendered sheet is mounted on offset paper with sodium silicate and other substances to make aluminum foil, it can also be printed. However, the aluminum foil itself is easy to oxidize and darken in color, and will fade when rubbed or touched, so it is not suitable for hot stamping on the covers of books and periodicals that are stored for a long time. Aluminum foil can be divided into thick foil, single zero foil and double zero foil according to the difference in thickness. The so-called double zero foil is the aluminum f...
