Sub-entry Shroud (SES)

In some Tundishes to maximize the life of Tundish, the fixed SEN is replaced by a combination of Tundish Nozzle and Sub Entry Shroud (SES), which is fitted to either a tundish nozzle or a tundish slide gate.

Our Submerged entry tubes have excellent thermal shock resistance and corrosion resistance properties and sophisticated anti-clogging quality features offering long sequence performance. This ensures less number of tube changes per sequence.

SES Tube Change Design:

Tube Change SES provides for excellent method for prolonging the life of Tundish. The worn-out SES is changed in a very short time by a new preheated SES which is again ready for further castings. The junction of SES with upper part is provided with Positive Argon Pressure to eliminate Air Suction through Joints. Upper Part which is a combination of Tundish Nozzle and Sliding Plate can be provided with Argon Bubling which minimizes Alumina Clogging. Lower SES also can be provided with Argon Bubling

Technical Benefit:

  • SES (Tube) changer with Stopper Control
  • Tube change in less than 2 seconds
  • Tube change at above the minimum casting speed
  • Tube change at above the minimum casting speed for most steel grades/ slab sizes
  • Increased safety by virtue of emergency shut-off facility (blank plate)
  • Argon direct injection in the upper part of the mono nozzle significantly decreases alumina clogging, unlike other systems
  • Argon injection onto the sliding surface of mono nozzle inhibits air ingress
  • Less tundish movement on the floor or with the crane

We can provide Refractory Components for all Types of Tube Changer Mechanism including for 3 plate Sliding Gate System.
