Production process of ultrathin double-face optical aluminum foil

Abstract

The invention discloses a production process of ultrathin double-face optical aluminum foil, comprising the following steps of: smelting: fusing raw materials into aluminum liquid by using a heat-storage type smelting furnace and entering into a casting-rolling machine after filtration; casting and rolling: introducing fused aluminum liquid in the casting-rolling machine to be aluminium foil blanks; cold rolling: rolling aluminium foil blanks to 0.78 millimeter by using a cold rolling machine after cooling the aluminium foil blanks to room temperature, then sending the aluminium foil blanks into an annealing furnace for uniformly annealing, and then rolling the aluminium foil blanks to 0.36 millimeter to obtain aluminium foil stocks; rough rolling: roughly rolling the aluminium foil stocks, wherein the reduced passes of rough rolling are 0.36 millimeter to 0.19 millimeter to 0.09 millimeter to 0.043 millimeter; medium rolling: carrying out medium rolling on the roughly rolled aluminium foil stocks, wherein the educed passes of medium rolling are 0.043 millimeter to 0.021 millimeter; and finish rolling: carrying out finishing rolling on the medium-rolled aluminium foil stocks, wherein the reduced passes of finish rolling are 0.021 millimeter to 0.011 millimeter, thereby obtaining aluminum foil finished products. The invention can reduce tape breakage rate in the production process of the aluminum foil by adopting the production process of the ultrathin double-face optical aluminum foil, thereby stably producing the ultrathin double-face optical aluminum foil in batch.

Description

technical field [0001] The invention relates to a production process of double-sided glossy aluminum foil, in particular to a production process of ultra-thin double-sided glossy aluminum foil. Background technique [0002] At present, my country has become the world's largest aluminum foil production country, and the technology of aluminum foil production is becoming more and more mature. Aluminum foil products have also been widely used in food packaging, pharmaceutical packaging, air conditioners, electronics and other industries, and the development prospects are very broad. The aluminum foil products produced in my country are divided into two types according to the surface state: double-sided smooth aluminum foil and single-sided smooth aluminum foil. , the product produced by this process, its upper and lower surfaces are in direct contact with the roll, and the gloss on both sides is consistent with the roll, which is relatively bright; the single-sided light aluminum...

AI Technical Summary

Problems solved by technology

Since the thickness of the aluminum foil is less than 0.012mm, it is very difficult to produce by the single-sheet rolling process. Generally, the double-rolling method is used for production, that is, the produced product is a single-sided light aluminum foil, but in the electronics industry and abroad In the fields of food containers and other fields, more and more users require the use of 0.011 mm double-sided aluminum foil products, and since the thickness of 0.011 mm is close to the limit state of product sheet rolling in the production process of aluminum foil, the production process is more difficult , the existing production process frequently breaks the belt, and it is difficult to produce high-quality products in a stable and mass-produced manner
