Abstract

The invention relates to the technical field of preparation of aluminum rolls, and particularly discloses a method for eliminating surface unevenness of an aluminum alloy roll. The method comprises the step that after being coiled, the aluminum roll is placed in an aluminum roll annealing furnace so as to be annealed, wherein the annealing temperature is 140-160 DEG C, the heating temperature is 6-10h, and the heat preservation time is 18-24h. According to the method, aluminum alloy is tempered or annealed repeatedly in the rolling process; the rolling reduction, the components of rolling oil,an rolling oil spraying system and the temperature are generally adjusted in the industry to reduce or eliminate the surface unevenness of the coiled aluminum roll, but the measures cannot effectively reduce or eliminate the surface unevenness of the aluminum roll; and according to the technical scheme of the invention, after being coiled, the aluminum roll is placed into the annealing furnace tobe annealed again, so that the surface unevenness of the aluminum roll is effectively reduced and eliminated.

Description

technical field [0001] The invention relates to the technical field of aluminum coil preparation, in particular to a method for eliminating surface unevenness of alloy aluminum coils. Background technique [0002] The 5052 alloy is an AL-Mg alloy. Magnesium is the main alloying element in the 5052 alloy. It is the most widely used anti-rust aluminum. This alloy has high strength, especially high fatigue resistance, plasticity and durability. It is highly corrosive and is often used to prepare aluminum sheets or foils. [0003] Due to the high strength of the 5052 alloy material, its tensile strength is generally required to be 320MPa ~ 380MPa. Therefore, in the process of preparing aluminum coils, especially when the aluminum foil is about 0.06mm, the normal rolling method is used to roll until the thickness of the finished product is 0.06mm. , the entire surface of the material will appear uneven. At the same time, as the thickness of the finished product decreases, the un...
