Roll of aluminum foil supply

Haomei have rich experience on supply roll of aluminum foil and the aluminum foil roll produced has a minimum thickness of 0.0025 mm and a width of 1800 mm. The aluminum foil jumbo roll is rolled without roll seam rolling, and the rolls are always in an elastic flattened state. The control of the thickness of the aluminum foil is achieved by adjusting the rolling force, the rolling speed and the control tension during rolling.

In rough rolling, the thickness of the aluminum foil is controlled by rolling force, when the rolling is performed, the thickness of the aluminum foil roll is thinned as the rolling speed increases, the larger the tension, the smaller the thickness. In order to prevent the chip, the tension is usually 0.2 to 0.4 of the conditional yield strength of the aluminum foil material. In low-speed rolling, “thick oil” or “thin oil” is often added to the lubricating oil to adjust the rolling thickness of the aluminum foil. Lubricant and roll conditions have a significant impact on the quality of the aluminum foil roll. The aluminum foil blank is from a cold rolled aluminum coil and is generally annealed at 340 to 480 ° C and has a thickness of 0.4 to 0.7 mm. The rolling deformation rate during rolling is about 50%, and the total deformation rate is over 95%. Roll of aluminum foil with a thickness of less than 0.01 to 0.02 mm shall be rolled and double rolled.
