Apparatus for continuously casting lead strip at various rates upwards of about 8 ft. per minute including a nonturbulent, constant-head, constant-temperature source of dross-free melt, an open-ended casting nozzle, an insulator thermally isolating the nozzle from the source and an aromatic polyimide seal at the inlet of the nozzle. Melt is pumped upwardly through a standpipe which is open midway to the nozzle. An adjustable weir atop the standpipe controls the metalostatic head above the casting nozzle, and a reversible pump permits ready aborting of a casting run.
