Tube Changer Mechanism

IFGL offers customised Tube Changer Solution for Slab casters.

Tube Changer Mechanism (TCM) is the safest and economic solution for long sequence Slab casters that demand high productivity with high steel quality. The system is used for quick change of Sub Entry Shroud (SES) without raising the Tundish or stopping the casting process.
Tube Changer Mechanism operate with optimized contact pressure for a metal tight SES change operation. The mechanism is capable for emergency strand shut-off with refractory blank plate.
IFGL offers customised Tube Changer solutions for Slab casters that are extremely safe, have long service life and require minimum running maintenance.

Hydraulic Drive System Direct Acting
Pneumatic Drive System Bell Crank
Electric Drive System

TCM HY-1 : Bell Crank

TCM HY-2 : Direct Acting

Direct drive hydraulic cylinder, sequence actuated by a single switch.


Tube Changer Refractories

Tube Changer Mechanism uses Mono-Nozzle with Sub Entry Shroud and Monoblock Stopper to ensure effective and safe flow control from Tundish to Mould. TCM refractories have efficient dual Argon purging arrangement in Nozzle seat and Sub Entry Shroud interface area to reduced Alumina clogging.
  • Customised refractory design through CFD modelling.
  • No gap SES design to prevent finning.
  • Dual Argon purging arrangement
