In the present study, ability of the high speed twin roll casting
of 5182 aluminium alloy was investigated. The high speed twin roll
casting was tried by two kinds of twin roll casters. One is an
unequal diameter twin roll caster and the other is a vertical type
high speed twin roll caster. In the previous study of the high speed
twin roll casting, the copper roll was used to increase casting speed.
The mild steel roll was used to make the roll-cost lower in stead of
the copper roll in the present study. Some devices were adopted to
increase the roll speed. In this report, surface condition,
microstructure and bending ability of the 5182 strip cast by the high
speed twin roll caster were shown.
