Refractory tundish nozzle
Blowing argon through tundish nozzle seat to avoid alumina clogging. Same time blowing the slide plate groove to avoid air going in slide plate to ensure steel liquid purity . Purging upper nozzle increased a big range of the tundish using life , reduced cost. Till to now, slab tundish ‘s integrate using life exceed 14 hours with adopting tundish nozzle.
Tundish Purging upper nozzle had adopted in varies of slab tundish, the using life had exceed other countries same material’s products./
We has developed 20 patterns of tundish nozzle easily configured to meet customer specifications, yet rugged enough to withstand the challenging position at the bottom of the tundish as a link between a stopper and a subentry nozzle or for slab casters which have tube changers. The seat of our tundish nozzles is specially designed to prevent erosion caused by molten steel. We also incorporate argon in the body of the tundish nozzle to prevent aluminum contamination blockage in the molten steel and it is sufficiently stable to withstand possible tundish chemical corrosion
