Abstract
A twin roll caster to cast clad strip was designed and assembled. This twin roll caster could cast clad strips of aluminum alloys at the speed of 20 m/min. Thickness of the clad strip was about 2.0 mm. The clad strip had a clear interface between the two strips. The clad strip was connected strongly at the interface. Therefore, the clad strip did not peel off at interface after continuous bending until broken. Clad ratio of the thickness between overlay strip and base strip was 2:1 · 1:10. Alloy that melting point was lower than the other was suitable for overlay strip. Roll speed, cooling distance of base strip, temperature of the melt for overlay strip were important factors to cast sound clad strip.
