Manufacturing Process for 5052 H32 Aluminum Circles for Tank Covers

• Smelting: During the smelting process, aluminum ore is mixed with other alloy elements (such as magnesium) and heated to melt into liquid aluminum. This step ensures that the aluminum alloy's chemical composition meets the standards and removes impurities.
• Casting: The molten aluminum is poured into molds and allowed to cool and solidify into ingots. Casting can be performed using continuous casting or mold casting methods. The cast ingots have larger dimensions and typically require further processing.
• Milling: The cast ingots undergo preliminary milling to remove surface roughness and shape the ingots to a form close to the final product.
• Cutting: The milled ingots are cut to the required length, preparing them for subsequent processing steps.
• Milling: Additional milling is performed to ensure the cut aluminum ingots have a smooth surface and meet the required dimensional tolerances.
• Homogenizing: The milled aluminum ingots are heated to a uniform temperature to eliminate internal stresses and improve their workability. The homogenizing process helps enhance material uniformity.
• Hot Rolling: The homogenized aluminum ingots are rolled through a hot rolling mill to gradually reduce their thickness to the desired level. Hot rolling improves the material's microstructure and mechanical properties.
• Cold Rolling: After hot rolling, the aluminum material undergoes cold rolling to further reduce thickness. Cold rolling enhances the surface finish of the aluminum circles and allows for more precise thickness control.
• Recoiling and Cleaning: The cold-rolled aluminum coils are recoiled to ensure uniform shape and cleaned to remove oxides and oil from the surface.
• Intermediate Annealing: After cold rolling, the aluminum material undergoes intermediate annealing to remove work hardening from the cold rolling process and improve machinability.
• Cold Rolling: The annealed aluminum is cold rolled again to further reduce thickness to the final specifications and improve surface finish.
• Stabilizing Annealing: After cold rolling, the aluminum undergoes stabilizing annealing to ensure stable mechanical properties and compliance with design requirements.
• Straightening: The aluminum material is straightened to eliminate any deformation or internal stresses caused by processing, ensuring the geometric dimensions and surface flatness of the product.
• Punching: The aluminum material is punched to form round aluminum circles, ensuring that their diameter and surface quality meet the standards.
• Packaging and Shipping: The finished aluminum circles are packaged to prevent damage during transportation and shipped to customers.
