Abstract
A discharge device discharges liquid steel into a roller crystallizer for the continuous casting of thin strip. The discharge device reduces turbulence at the meniscus to a minimum so as to eliminate the relative defects on the cast strip by passing the steel between two crystallizer rollers. A relative casting process provides expedients for improving the steel feeding from a tundish to the crystallizer. Advantageously, the feeding of guided steel jet streams inside the nozzle, or delivery nozzle, eliminates the disturbance at the meniscus caused by the air bubbles which can form when free-falling jet streams come into contact with the air.
