2.Description

In Europe aluminium experiences high rates of recycling, ranging from 42% of beverage cans, 85% of

construction materials and 95% of transport vehicles.Recycled aluminium is known as secondary aluminium, but maintains the same physical properties as primary aluminium. Secondary aluminium is produced in a wide range of formats and is employed in 80% of alloy injections. Another important use is for extrusion.

White dross from primary aluminium production and from secondary recycling operations still contains useful quantities of aluminium that can be extracted industrially.The process produces aluminium billets, together with a highly complex waste material. This waste is difficult to manage. It reacts with water, releasing a mixture of gases (including, among others, hydrogen, acetylene, and ammonia), which spontaneously ignites on contact with air;contact with damp air results in the release of copious quantities of ammonia

gas. Despite these difficulties, the waste has found use as a filler in asphalt and concrete.

Q:How are aluminum coils tested for thickness and flatness?: Various methods are employed to test aluminum coils for thickness and flatness, ensuring they meet the necessary specifications. One commonly used method is non-destructive eddy current testing. This involves passing an alternating current through the coil and measuring the changes in the magnetic field caused by the eddy currents induced in the aluminum. By analyzing these changes, the thickness of the coil can be determined. Ultrasonic testing is also utilized to measure the thickness of aluminum coils. This method involves sending ultrasonic waves through the coil and measuring the time it takes for the waves to bounce back. It is highly accurate and capable of identifying any variations in thickness throughout the entire coil. To assess the flatness of aluminum coils, a straight edge or laser beam is often employed. The coil is placed on a flat surface, and the straight edge or laser beam is positioned across its surface. Any deviations from perfect flatness can be easily identified by observing the gaps or irregularities between the coil and the straight edge or laser beam. For a more comprehensive analysis of flatness, advanced technologies like laser profilometry can be used. This involves creating a three-dimensional map of the coil's surface, providing highly detailed information about any variations in flatness across its surface. In conclusion, aluminum coils are subjected to rigorous testing procedures to ensure they meet the necessary standards for thickness and flatness. These tests are essential in maintaining the quality and reliability of aluminum coils, particularly in applications where precision and consistency are crucial.
