An unequal diameter twin roll caster was adopted in the strip casting of aluminum alloy. This caster allowed easy start of casting, high speed roll casting, second cooling and casting of hypereutectic Al-Si alloy strip. Al-20%Si alloy, which has wide freezing zone, could be cast into the strip continuously at the speed of 20m/min. Primary Si was very fine by the effect of excellent cooling ability. The diameter of the large roll (lower roll) was 1000mm, and that of smaller roll (upper roll) was 250mm. The nozzle of this caster was assembled from 4 pieces of plates, and the attachment of the nozzle to the caster was very easy.
