Melt ejection twin roll caster for the strip casting of aluminum alloy

A melt ejection twin roll caster (METRC) was devised for the high-speed roll casting of aluminum alloy to secure sound surfaces. This caster can cast A5182 alloy as strip at a speed of up to 120 m/min. The strip surface can be improved by ejecting the melt onto the roll. The strip does not stick to the roll because the 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 METRC is very fine.
