Mono Block Stopper / Tundish Ladle Shroud Sub-Entry Nozzle (SEN)

Mono Block Stopper/ Tundish

Mono Block Stopper (MBS) are used to control the flow of steel through the sub-entry nozzle or the tundish nozzle. Dalmia GSB’s Monoblock Stoppers are known for their excellent performance, especially for high Ca ppm steel and they are also tailor-made for individual plant requirements.
Tundish is an intermittent vessel between the ladle and the mould. It acts as a reservoir where liquid steel gets residence time before casting. This helps non-metallic inclusions to float on the surface and allows clean steel to be cast.

Solutions for Mono Block Stopper

Made with Isostatically pressed Alumina Carbon or Magnesia Carbon composites, we tailor-make MBS to suit specific customer requirements.

We also offer:

MBS with and without argon injection system
Composite type MBS with high spalling resistant material at the body and erosion resistant material at the nose
Specially designed MBS for foundries
Special Features Special material like Zirconia Carbon / Magnesia Carbon used at Tundish slag zone acts as corrosion resistant material
MBS with Magnesia-carbon nose can be used for high Ca ppm steel and High corrosion resistant material at the nose for MS & SS grade steel

Solutions for Tundish

These are the solutions for Tundish:

Special Features:

Sub-Entry Nozzle (SEN) / Ladle Shroud

SEN is used to guide the flow of steel from Tundish to mould during continuous casting. Materials like Zirconia Carbon and Magnesia-carbon are used at different zones to make it suitable for longer sequence casting. With isostatically pressed carbon composites and magnesia carbon in the seat area, Dalmia GSB’s Sub Entry Nozzles are most popular for making special grades of steel.
Ladle shrouds are special equipment that protect and control the flow of steel from Ladle to Tundish. Dalmia GSB’s Ladle Shrouds offer superior corrosion and spalling resistance, ensure low carbon and nitrogen pick-up, making them an ideal choice.

Solutions for Sub-Entry Nozzle

These are the solutions for Sub-Entry Nozzle (SEN):

Special Features:

SEN with Zirconia-Graphite at “Mould powder area” offers excellent corrosion resistance
With Magnesia Carbon in seat area, it is used in special grades of steel
Flat type SEN is particularly useful for narrow sections
With effective use of nano-zirconia at slag band, it is used for achieving higher life

Solutions for Ladle Shroud

Made with Isostatically pressed Alumina Carbon composites, our Ladle shrouds are tailor-made to meet specific requirements of customers. Incidentally, we are known to offer the widest range of tailor-made designs and our shrouds come in all types, shapes and sizes:

Composite type
Can type
Porous type
Groove type
Y-shaped
Bell-shaped
Encased in steel
With Cera cup or pyro-plastic sealing gaskets

Special Features of various types of ladle shrouds Composite type shrouds offer superior corrosion resistant material in slag zone and spalling resistant material in body for longer sequence casting.

Shrouds with steel encasing in neck area provide additional strength. Y-shaped shrouds help in neck strengthening & reducing Nitrogen pick up
Shrouds with argon injection system through in-built channel / porous ring / groove/ steel CAN help reduce Nitrogen pick up
Shrouds with pyroplastic sealing gasket reduce Nitrogen pick up
Bell shaped design helps reduce turbulence in tundish
