Detoxification of impurities using cavitation
Improving the recycling rate of aluminum (Al) is becoming more important. Recycled Al contains impurities such as iron, silicon, and zirconia, which form intermetallic compounds(IMC) and reduce its mechanical strength. Convectional methods use ultrasonic vibrations to refine these compounds, but scaling up the process remains a challenge. To solve it, the inventor has invented a machine that applies cavitation treatment to molten recycled Al. This simple machine design makes it easier to scale up and use in industrial applications compared to conventional methods. Experimental results showed that the machine effectively refined IMC and improved the strength of recycled Al. This invention could significantly advance aluminum recycling.
