Investigates the effects of roll speed on thin A6061 sheet quality in vertical twin-roll casting, indicating potential improvements in fabrication methods.
This paper reports on the vertical twin roll casting of aluminum alloy A6061. In this paper, we investigate the conditions under which thin aluminum alloy A6061 sheets can be fabricated by the twin roll casting method, which can directly fabricate thin sheets from molten metal. The effects of roll speed on sheet continuity, surface properties, and thickness were investigated, and the characteristics of twin-roll casting were evaluated by observing the microstructure of the sheets and conducting Vickers hardness tests. The surface of the fabricated sheets consisted of metallic luster and cloudy areas, and fine solidification cracks were observed in some places.
