DELIVERY DEVICE AND METHOD FOR USING THE SAME

摘要

Discharge device for discharging liquid steel into a roller crystallizer for the continuous casting of thin strip capable of reducing 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 is also described, said process providing for particular expedients for improving the steel feeding from the 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 form when free-falling jet streams come into contact with the air, as occurs in the known devices and plants.
