High Quality Aluminum Foil For Container 3003 H24
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.
In order to develop aluminum alloy foils that can be punched into multi-cavity fast food containers, by adjusting the chemical composition of 3003 aluminum alloy and formulating an appropriate annealing process system, the process performance of 3003 aluminum alloy H24 foil is improved. Cast-rolled blanks are used to produce aluminum alloy foil that can be punched into three-cavity containers, making 3003 aluminum alloy foil an environmentally friendly fast food container material that replaces plastic and foam.
The manufacturing method of aluminum alloy foil for aviation meal boxes includes the following steps: (1) Ingredients: The chemical composition is prepared according to the following weight percentages: Si≤0.1%, Fe≤0.2%, Cu≤0.1%, Mn≤0.1%, 2.4 %≤Mg≤2.8%, 0.15%≤Cr≤0.25%, Zn≤0.05%, 0.1%≤Ti≤0.15%, the balance is Al; (2) smelting (3) refining (4) grain refinement (5 ) Degassing (6) Filtering (7) Casting (8) Sawing (9) Milling (10) Homogenizing heating (11) Hot rolling (12) Cold rolling (13) Cleaning and trimming (14) Intermediate annealing (15) ) Foil rolling (16) Slitting (17) Degreasing and finishing annealing (18) Inspection. Compared with 1145, 1100, 8011, 8006, 3003 aluminum alloy foil, the aluminum alloy foil of the present invention has high strength, is easy to form, and does not punch The characteristics of cracking and smooth surface meet the quality requirements of aviation meal boxes.
Aluminium Foil with a Purity of 99 Due to the annealing temperature and final adjustment process, the foil is in a completely sterile state
