ABSTRACT:
A shroud or submerged pour tube which has a sealing cup of an essentially frustoconical configuration at its upper end is disclosed. The sealing cup matingly engages a bullet-shaped nose on the lower portion of the collector nozzle extending downwardly from the valve. The combination of the collector nozzle and the shroud and the joint are held in compressive and oriented relationship by a shroud support assembly. The shroud support assembly has adjustable length arms to permit tilting the shroud axis for alignment at the lower end of the shroud. This urges a line contact at the joint at the upper end of the shroud where it engages the bullet nose of the collector nozzle. The support assembly also may be mounted with flexibility for moving on the XY axis where the Z axis is the axis of the pour tube or shroud in those two plate situations where the collector nozzle shifts laterally during the on and off condition and also during throttling.
