Submersed nozzle

Quick-exchange SEN for Slab Caster

1.Sliding plate ensures perfect seals and quick-change.
2.Steel shell ensures sliding plate in perfect condition andcooperate with mechanical structures.
3.The body adopts Al-C materials with perfect anti-thermalshock property.
4.Al-Zr-C compound materials has perfect anti-slagproperties.
5.Adopts perfect anti-corrosion materials, the side mouthspossess higher anti-corrosion properties, which decreasethe risk of turbulence of molten water carrying slags.
6.Insulating fiber keep the temperature effectively andprevents molten water from condensation .
