SubmergedNozzle / Submerged Entry Nozzle/Submerged Entry Shroud is manufactured inAlumina Carbon (Al2O3-C) quality and isostatically pressed. Special protectivecoating is applied to provide oxidation resistance and decarburisation.
Sub-entryNozzle/Sub-entry Shroud is used to control flow of liquid steel from"Tundish to Mould". It prevents re-oxidation of steel between thetundish and the mould.
SENplays an important role in protecting the molten steel from air oxidation whenit flows from the tundish to the mould. It also averagely distributes steelinto the mould and control the steel fluid state in the mold.
LQseries of SEN features good thermal shock resistance,stability, corrosion resistance and anti-mechanicalfracture. Every batch of products have passed rigorous NDT X-ray test beforelaunching into the market.
