Roll Aluminium Foil
In 2019, the global industrial aluminum foil coil market reached xx billion yuan, and it is expected to reach xx billion yuan in 2026, with a compound annual growth rate (CAGR) of xx%.
The development status and future development trend of global and Chinese industrial aluminum foil rolls are analyzed from the perspective of production and consumption, respectively, the main production areas, main consumption areas and major aluminum foil producers of industrial aluminum foil rolls. Focus on analyzing the product characteristics, product specifications, prices, output, output value of different types of products of major global and Chinese manufacturers, as well as the market shares Major manufacturers in the global and Chinese markets
Aluminum foil coil heating speed
1. The larger the width and diameter of the foil roll, the worse the thermal uniformity of the foil roll. If the heating speed is too fast, the temperature difference between the surface of the aluminum foil roll and the core is likely to be too large. Due to thermal expansion and contraction, the surface of the roll There will be a big difference between the volume change of the core and the core, which will generate a great thermal stress, and make the surface of the wave roll bulge and edge. The effect on the heating speed of aluminum foil above 0.02mm is not obvious, while the heating speed of thin foil below 0.02mm should be appropriately reduced. Low-speed heating is also helpful to prevent the adhesion of aluminum foil.
2. Rapid heating is easy to obtain a fine and uniform structure and improve its performance, such as 3A21 alloy aluminum foil. In order to prevent the local coarse and uneven crystal grains that are easy to occur during the annealing process, the method of rapid heating is usually used.
3. In actual production, the heating speed should be increased as much as possible under the premise of ensuring quality.
4. Annealing furnace with axial flow fan, due to the fast air circulation and uniform temperature, the heating speed can be appropriately increased. At present, most of the aluminum foil annealing furnaces are air circulation resistance furnaces, with a furnace capacity of 10-30t, with automatic temperature control, over-temperature alarm and other functions, and the uniformity of furnace temperature [examination|large|degree] is below ±5℃.
