Abstract
A nozzle for delivering molten metal to a casting pool of a twin roll strip caster is formed in two halves and comprises an upwardly opening trough (61) to receive falling supply streams of molten metal and outlet openings (64) at the bottom of the trough. Nozzle end formations (87) define reservoirs (88) to receive separate supply streams of molten metal and flow passages (95) to direct metal from the reservoirs across pool confining end closures of the caster. Each reservoir (88) is separated from trough (61) by an upstanding wall (70) which functions as a weir for metal in the reservoir such that metal can flow over it into the trough when the reservoir is full.
