In-Line Rolling of Aluminum Alloy Strip Cast by a High Speed Twin Roll Caster

Article Preview

In-line rolling was operated on the as-cast strip cast by a vertical type high speed twin roll caster. The AA6022 and AA6111 strip was tested. The casting and rolling speed was 60m/min. Reduction was from 20% to 55%. The temperature of the rolling was within from 400oC to 450oC. The porosity and crack in the strip were improved by the in-line rolling. The in-line as rolled strip was cold rolled down to 1mm, and T4 heat treatment was operated. The microstructure of the strip, on which in-line rolling was operated, became uniform at thickness direction than the microstructure of the strip on which only the cold rolling was operated. The surface defects like the ripple mark and trace line of the nozzle were improved.
