Nozzle for the continuous casting of lead

摘要

A continuous casting nozzle for lead strip adapted for cooling with water or the like. Primary and secondary cooling channels are arranged in paralleling relation and intercommunicated by a plurality of ports which direct turbulent streams of water from the secondary cooling channel against the hot surface of the primary cooling channel to purge any vapor films formed thereon. The water exits the primary cooling channel through passages beneath the surface of the casting mold and exits the nozzle so as to bathe the exiting cast strip in coolant.
