Where To Buy Aluminium Foil ?
Our company has extremely high quality requirements. Thickness control: Accurate and stable thickness is the basic and important technical index of aluminum foil products. The height of the automatic thickness control is mainly guaranteed by the equipment's own capabilities.
At the same time, thickness fluctuations are also inherited. Relatively stable and small thickness fluctuations can be basically eliminated by subsequent rolling, but from hot rolled coils to aluminum foil products, sudden changes and large thickness fluctuations can be inherited. Stable thickness control is mainly considered from the following four aspects: accurate alloy composition; stable rolling speed; normal hydraulic system and thickness measurement system; proper roll roundness and bearing accuracy.
In the rolling and coiling process, the accumulation of crown should also be avoided. The thickness of the middle position of the coil keeps accumulating, and the diameter deviation between the middle of the coil and the two sides of the coil will gradually increase. As a result, the tension distribution in the width direction of the strip is uneven, and the tensile stress of the strip in the middle of the strip becomes larger and larger as the diameter of the strip increases, which provides an error signal for the strip. Measurement. And affect the automatic control of profiles.
Similarly, because aluminum foil blanks are softer than other alloys, the cumulative effect of this convex surface has a greater impact on the shape of aluminum foil blanks. Therefore, for the shape of aluminum foil, attention should be paid to the shape of the blank, and the shape of the blank should focus on the influence of its offline shape and convexity accumulation. Another important technical indicator is high strength/high elongation.
Aluminium Foil Dealers battery foils also require high coefficients, high strength/high elongation.
