Haomei Aluminium is one of the famous aluminum foils providers in China, which has advanced production line to ensure the quality of alu foil product. Because of its excellent characteristics, aluminum foil is widely used in food, beverages, cigarettes, medicines, photographic substrates, household daily necessities, etc., and is usually used as packaging material, electrolytic capacitor material, heat insulation material for buildings, vehicles, ships, houses, etc.; As decorative gold and silver thread, wallpaper, various stationery printed matter and decorative trademarks of light industrial products. Among the above-mentioned various uses, the most effective use of aluminum foil is as a packaging material.
Aluminum foil is a soft metal film, which not only has the advantages of moisture proof, air tightness, shading, abrasion resistance, fragrance retention, non-toxic and tasteless, etc., but also because of its elegant silver-white luster, aluminum foil is easy to process beautiful patterns and various colors. Patterns are more likely to be favored by people. As aluminum foils providers, Haomei Aluminium have adopt highly advanced and automatic production line. The selection principle of pass processing rate is as follows:
1, Under the premise that the equipment capacity allows the rolling oil to have good lubrication and cooling performance, and can obtain good surface quality and plate shape quality, the plasticity of the rolled metal should be fully utilized, and the large pass processing rate should be used as much as possible to improve the rolling mill Production efficiency.
2, The processing rate of the pass shall be fully considered in terms of mill performance, process lubrication, tension, original roll shape, and rolling speed. The rolling pass processing rate of the original or semi-hard aluminum foil blank is generally 40%-65%, and the rolling pass processing rate of the hard aluminum foil blank is generally 20%-40%.
3, For products with high requirements for thickness deviation, surface quality, and shape quality, a smaller pass processing rate should be selected.
4, For rolling mills with automatic thickness control system and automatic shape control system, a larger pass processing rate can be appropriately adopted.
5, The selection of pass processing rate should be based on actual conditions, and after continuous exploration and summary in field practice based on equipment, quality, production efficiency, etc., it is finally determined.
