  • Patent number: 5490554
    Abstract: A teeming arrangement for a continuous casting apparatus comprises a tundish, a casting nozzle which projects from the bottom of the tundish, and a stopper rod for regulating flow through the casting nozzle. The nozzle has an inlet end and an outlet end and narrows progressively from each of these ends to the middle of the nozzle. The distance from the middle of the nozzle to either end is at least 7 cm. The stopper rod is movable between a closed position in which it seals the middle of the nozzle and an open position in which the nozzle is unobstructed. In the open position, the stopper rod and the nozzle define an annular gap, and the gap has a section which extends from the inlet end of the nozzle partway to the middle and narrows in a direction from the inlet end towards the outlet end. During casting, molten material is discharged from a bath in the tundish via the nozzle and forms a molten pool in a mold.
