Problems solved by technology

For example, due to the increase in varieties of pure aluminum foil for industrial use and the update of production equipment, especially the introduction of foreign equipment, manufacturers have put forward higher requirements for the performance of aluminum foil for wire shielding and moisture resistance; Insufficient attention to quality problems, such as surface oil spots, corrosion, holes and low elongation, resulting in too low yield, so in the fierce market competition, not only no economic benefits at all, but also may lose money

Embodiment Construction

[0019] The low energy consumption aluminum foil processing technology in this embodiment, its technological process is: raw material aluminum → batching → melting → refining → purification → casting → cold rolling → primary trimming → rolling → secondary trimming → annealing, the batching is A mixture of sodium fluoroaluminate and industrial ammonium chloride, and a two-way combination is used to extract slag and gas during processing.

[0020] Among them, the mixing ratio of sodium fluoroaluminate and industrial ammonium chloride is 2-3:1. Sodium fluoroaluminate and industrial ammonium chloride are used to formulate and carry out deep extraction of slag and steam from aluminum water, and then use nitrogen to extract steam. The aluminum foil products produced can basically achieve no bubbles and slag inclusions on the surface.

[0021] Refining is carried out under the state of chlorine gas, which converts aluminum into alumina. In order to reduce the burning loss of magnesium...

Abstract

The invention relates to a low-energy-consumption type aluminum foil processing technique and belongs to the technical field of physicochemical treatment. The technological process comprises the steps of preparation of raw material aluminum, preparation of an auxiliary material, melting, refining, purifying, casting, cold rolling, edge cutting for the first time, rolling, edge cutting for the second time and annealing; and the auxiliary material is a mixture of sodium fluoroaluminate and industrial ammonium chloride, and in the processing process, a two-way combination method is adopted for slag and gas taking. The low-energy-consumption type aluminum foil processing technique is applied to aluminum foil processing, and has the advantages of high surface smoothness, low energy consumption and the like.

Description

technical field [0001] The invention relates to a low-energy-consumption aluminum foil processing technology, which belongs to the technical field of physical and chemical treatment. Background technique [0002] With the advancement of industrial technology, due to the advantages of light weight and good shielding effect of aluminum foil, the application field of aluminum foil is constantly expanding, and the performance requirements of users for aluminum foil are also getting higher and higher. For example, due to the increase in varieties of pure aluminum foil for industrial use and the update of production equipment, especially the introduction of foreign equipment, manufacturers have put forward higher requirements for the performance of aluminum foil for wire shielding and moisture resistance; Insufficient attention to quality problems, such as surface oil spots, corrosion, holes and low elongation, resulting in too low yield, so in the fierce market competition, not o...
