The process of making لفائف الالومنيوم typically involves several steps. هنا نظرة عامة على العملية:
يصب: تتمثل الخطوة الأولى في صهر سبائك الألومنيوم أو الألمنيوم المعاد تدويره لتشكيل سبيكة ألمنيوم منصهرة. ثم يصب الألمنيوم المصهور في قوالب كبيرة مستطيلة الشكل تسمى السبائك.
الدرفلة على الساخن: يتم تسخين سبائك الألومنيوم وتمريرها عبر سلسلة من مصانع الدرفلة. The ingots are gradually reduced in thickness and lengthened in the process. This hot rolling process involves repeatedly passing the aluminum through sets of rollers to achieve the desired thickness.
المتداول الباردة: After hot rolling, the aluminum strip is further processed through a cold rolling mill. Cold rolling involves passing the aluminum strip through a series of rollers at room temperature. This process refines the material, improves its surface finish, and reduces its thickness to the desired gauge.
التلدين: The cold-rolled aluminum strip may undergo annealing, which involves heating it to a specific temperature and then cooling it slowly. Annealing helps relieve internal stresses in the material and improves its formability.
الحز: The cold-rolled and annealed aluminum strip is typically slit into narrower coils of the desired width. Slitting machines cut the wide strip into narrower strips, which will become individual coils.
Coil Coating (Optional): If the aluminum coils are intended for specific applications, they may undergo a coil coating process. Coil coating involves applying a protective or decorative coating to the surface of the aluminum coils. This coating can provide corrosion resistance, improve aesthetics, or enhance specific properties.
التعبئة والتغليف: The final step involves packaging the aluminum coils for transportation and storage. The coils are typically wound tightly and secured with bands or straps to prevent unraveling or damage during handling and shipping.
