Abstract
The temperature of an aluminum alloy (Al-6%Si) strip cast using a vertical-type high-speed twin-roll caster was measured by inserting a K-type thermocouple into the strip. The effects of the roll diameter on supercooling, cooling rate, and temperature at the roll bite were investigated. It was found that the roll diameter affects the cooling condition of the strip. The thickness of the thermocouple was 0.1 mm and the sampling rate was 100 Hz. Copper rolls with diameters of 300 and 600 mm, respectively, were used. The roll width was 100 mm and the roll speed was 30 m/min. The roll load was 5 or 20 kN.
