CASTING AL SHEETS ON A LAB-SCALE, SINGLE-ROLL, CONTINUOUS SHEET CASTER

The research described here deals with the design and fabrication of a laboratory-scale single-roil continuous caster and then the casting o f aluminum sheet under various operating conditions. The results indic ate that the sheer thickness decreases with increasing rotational spee d and melt superheat but increases with increasing stand-off distance and metal head in the tundish. The tundish opening size and the coolin g conditions at the inner surface have only it marginal effect on the thickness. After the initial stages of solidification, the sheet thick ness varies move or less linearly with the square root of the solidifi cation time.
