摘要

Metallurgical quality of roll casting sheet is crucial to ensure the performance of aluminum foil. An electromagnetic purification system was installed in a twin roll casting line in order to improve the molten metal cleanliness. Metallographic analysis shows that inclusion particles larger than 10 μm can be eliminated from molten aluminum by electromagnetic purification and a total inclusion removal efficiency of 75% is achieved additional to the filtration by a ceramic foam filter. The electromagnetic purification system operated reliably and consistently during the casting campaign.
