Integral submerged entry nozzle
整体水口
One continuous refractory from the tundish seat to the mould.
- Application
- Tundish seat → below the mould steel surface

Product overview
Here, integral nozzle means a one piece submerged entry nozzle: the inlet seat, tube and submerged end form one component. The seat can work with a stopper. This is a structural member of the submerged nozzle family, distinct from a tube joined through a quick change sliding interface.
- Product range
- Integral submerged entry nozzles with matched seat, length and outlets.
- Application context
- Tundish to mould installations arranged for a one piece nozzle.
Application and installation
The inlet sits at the tundish outlet and the continuous tube extends through the bottom into the mould. The diagram includes a stopper; review the full mounting envelope and orientation.
Structure and steel flow
With the stopper raised, steel passes around the nose into the inlet, down the bore and through the submerged outlets. The illustrated version uses side ports.
- 1
Inlet seat
Works with the stopper nose to define the flow gap.
- 2
Integral body
No quick change sliding joint is shown in this continuous body.
- 3
Slag line zone
Position and material depend on immersion and flux.
- 4
Submerged outlets
Opposed side ports and a closed axial base are illustrated.
Product range and matching considerations
| Integral construction | One component joins the seat and submerged end. |
|---|---|
| Side port option | Outlet arrangement and connection type are separate design choices. |
Name the structure precisely
Integral means one piece SEN here, not a separate upper nozzle.
Check installation space
Review length and mounting with both tundish and mould drawings.
Functions and selection considerations
Continuous passage
The inlet and submerged end belong to a single refractory component.
Stopper matching
The seat and stopper nose must have compatible profiles.
Submerged delivery
Outlet geometry directs steel into the mould below its surface.
Information for product selection
Drawings and operating details help confirm product fit and service requirements.
| Seat | Stopper nose, inlet profile and alignment requirements |
|---|---|
| Installation | Overall length, tundish bottom depth, support and mounting |
| Submerged end | Mould section, level, immersion and outlet direction |
| Service | Steel grade, temperature, flux and casting sequence |
Materials, dimensions and service requirements are subject to the agreed technical documents.
