The process of making алюминий катушкалар typically involves several steps. Мұнда процестің жалпы шолуы берілген:
Кастинг: Бірінші қадам - балқытылған алюминий қорытпасын қалыптастыру үшін алюминий құймаларын немесе қайта өңделген алюминийді балқыту. Содан кейін балқытылған алюминий құйма деп аталатын төртбұрышты пішінді үлкен қалыптарға құйылады.
Ыстық прокат: Алюминий құймаларын қыздырып, прокат стандарынан өткізеді. 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.
Суық прокат: 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.
Күйдіру: 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.
Slitting: 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.
Packaging: 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.
