Submerged Nozzle Lqsn - China

Submerged nozzle LQSN Submerged Nozzle / Submerged Entry

Nozzle/Submerged Entry Shroud is manufactured in Alumina Carbon (Al2O3-

C) quality and isostatically pressed.

Special protective coating is

applied to provide oxidation resistance and decarburisation.

Sub-entry

Nozzle/Sub-entry Shroud is used to control flow of liquid steel from

'Tundish to Mould'.

It prevents re-oxidation of steel between the

tundish and the mould.

SEN plays an important role in protecting the

molten steel from air oxidation when it flows from the tundish to the

mould.

It also averagely distributes steel into the mould and control

the steel fluid state in the mold.

LQ series of SEN features good

thermal shock resistance, stability, corrosion resistance and anti-

mechanical fracture.

Every batch of products have passed rigorous NDT

X-ray test before launching into the market.
