3003 H24 Aluminum Foil For Aluminium Container For Food Packaging
3003 alloy production of aluminum foil blanks for container foil casting and rolling production technology, involving the technical field of aluminum alloy processing technology. Involving the 3003 alloy production of aluminum foil blanks casting and rolling production process for container foils, including smelting-furnace purification, alloying-standing, and heat preservation —On-line purification, filtration—cast rolling—cold rolling—homogenization annealing—cold rolling—intermediate annealing—cold rolling—recoiling and trimming—inspection and packaging process. With the technical scheme of the present invention, the cast-rolling method can be used to produce 3003 Aluminum foil blanks for alloy container foils provide a short process and low-cost processing technology for 3003 alloy container foil blanks.
An aluminum foil for semi-rigid containers and its production process, including the following steps: (1) Choose high-strength, high-stretch aluminum foil of plan A or aluminum foil of plan B; (2) trial production process: smelting, casting and rolling (7.0 mm) cold rolling (0.6mm) intermediate annealing foil rolling (0.055mm) slitting finished annealing; (3) finally obtaining the finished product of plan A or the finished product of plan B. The present invention adjusts the chemical composition of 3003 aluminum alloy to make suitable The annealing process system has improved the process performance of the 3003 aluminum alloy H24 foil. The cast-rolled billet is used to produce aluminum alloy foil that can be punched into a three-cavity container, making 3003 aluminum alloy foil an environmentally friendly alternative to plastic and foam plastic Fast food container material.
3xxx series aluminum alloys are non-heat-treatable reinforced aluminum alloys, which have the advantages of moderate strength, excellent formability and good corrosion resistance, and are often used as raw materials for the production of semi-rigid container aluminum foil. The investment cost of aluminum alloy sheets produced by the casting-rolling method Low, short process flow, high production efficiency and low energy consumption. In recent years, it has gradually replaced the traditional ingot hot rolling method to prepare 3xxx aluminum foil wool.
Aluminum Foil For Decoration Alloy 3003 1100 Aluminum foil paper is mainly composed of base paper, aluminum layer and coating. Because of its gloss, smoothness and flexibility, the spray aluminum layer has high fastness, beautiful and environmentally friendly, and has good printing performance and mechanical processing performance, it has become a decorative industry new star.
