Henan Henry has extensive experience in the supply of aluminum foil rolls.The minimum thickness of the aluminum foil rolls produced is 0.005 mm and the width is 1800 mm. The giant roll of aluminum foil is rolled without a space between rollers, and the roll is always in a flat elastic state. The thickness of the aluminum foil is controlled by adjusting the rolling force, the rolling speed and the control tension during the rolling process.
In raw rolling, the thickness of the aluminum foil is controlled by the rolling force. When rolling, the thickness of the aluminum foil coil becomes thinner as the rolling speed increases. The higher the tension, the smaller the thickness. To avoid chipping, this tension is usually 0.2 to 0.4 of the conditional elastic limit of the aluminum foil material. In low speed lamination, "heavy oil" or "fine oil" is usually added to the lubricating oil to adjust the lamination thickness of the aluminum foil. The condition of the lubricant and the roller has a significant effect on the quality of the aluminum foil roller. The blanks of aluminum foil are cold rolled aluminum coils, which are generally annealed at 340 to 480 ° C and have a thickness of 0.4 to 0.7 mm. The rolling deformation speed during rolling is approximately 50%, and the total deformation speed exceeds 95%. Aluminum foil rolls with a thickness of less than 0.01 to 0.02 mm should be rolled and rolled twice.
