A melt ejection twin roll easter was devised for high-speed roll casting of aluminum alloy that has sound surfaces. This easter can cast A5182 alloy strip at the speed of up to 120 m/min. The strip surface can be improved by ejecting the melt on to the roll. The strip does not stick to the roll because of separating force is very small. Therefore, lubricant is not required in order to prevent the sticking of the strip at the roll. The microstructure of the strip cast using the melt ejection twin roll. easter is very fine.
