Embodiment Construction

[0016] In order to deepen the understanding of the present invention, the present invention will be described in further detail below in conjunction with the examples, which are only used to explain the present invention and do not constitute a limitation to the protection scope of the present invention.

[0017] A method for alleviating aluminum powder on the surface of 1235AH14 double zero foil material during rolling, comprising the following steps:

[0018] Step 1: controlling the addition ratio of rolling crude oil and rolling recovered oil in the rolling oil, the addition ratio of the rolling crude oil is ≥75%;

[0019] Step 2: Control the pressing amount of the rolling pass in the range of 40% to 50%, and divide the rolling process of 1235AH14 double zero foil material into billet rolling, intermediate rolling and rolling according to the rolling pass amount. Finished product rolling, the rolling pass of the billet rolling is: 6.8mm-4.0mm, the rolling pass of the interm...

Abstract

The invention discloses a method for reducing aluminum powder on the surface of a 1235AH14 double-zero foil material in the rolling process, which comprises the following steps of: firstly, dividing the rolling process of the 1235AH14 double-zero foil material into five rolling passes, controlling the pressing amount of each rolling pass according to 40-50% to realize optimal production, and then adjusting the surface roughness of a roller in the rolling process to reduce the aluminum powder on the surface of the 1235AH14 double-zero foil material. According to the invention, the rolling oil is added, so that the compression degree of an oil film in the rolling process is relieved, the adhesion amount of aluminum powder on the surface of the 1235AH14 double-zero foil material is reduced, and finally, by adjusting the acid value, ester value and alcohol ester of the rolling oil, the lubricating property of the oil film is enhanced while the strength of the oil film is improved, and the adhesion degree of the aluminum powder is relieved.

Description

technical field [0001] The invention relates to the field of aluminum alloy foil manufacturing, in particular to a method for reducing aluminum powder on the surface of 1235AH14 double-zero foil during rolling. Background technique [0002] 1235AH14 double-zero foil material is the most commonly used double-zero foil alloy on the market. It is widely used in food packaging, medicine, tobacco, building materials and other fields. Based on the requirements for product characteristics, it is necessary to strictly control the 1235AH14 double-zero The amount of aluminum powder attached to the surface of the foil material, and improper selection of factors such as the amount of rolling pass, the surface roughness of the roll, the way of cleaning the roll, and the control of oil products will lead to the amount of aluminum powder attached to the surface of the 1235AH14 double zero foil material. The increase will seriously affect the performance of 1235AH14 double zero foil materia...
