Abstract
Aluminum alloy strips were cast using a melt drag twin roll caster (MDTRC). Casting speed (roll speed) of MDTRC was much higher than that of conventional type twin roll caster for aluminum alloy. Microstructure of the strip became fine as the roll speed became high. Tensile strength and elongation of Al-6%Si strip cast using MDTRC was better than that of ingots cast by mold casting.
