Tube Changer Mechanism for Slab Caster  
 
 
  • Hydraulic / Pneumatic drive
  • Blank Plate Support System
  • Detachable drive unit
  • Emergency shut-off facility
  • Pushers - Coil Spring
  • No need of cooling
  • Sophisticated Gas delivery system through Mononozzle without chance of any blockage
  • Tube Guides for perfect alignment
  • SES (Tube ) changer with Stopper Control
  • Quick change of SES (Tube) without stopping the cast
  • Tube change without raising the tundish
  • Tube change in less than 2 seconds
  • 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 mononozzle significantly decreases alumina clogging unlike other systems
  • Argon injection onto sliding surface of mononozzle inhibits air ingress
  • Longer sequence without the need to use large complex pouring tubes
  • Less tundish movement on the floor or with the crane
  • Increase in the number of heats per tundish and per sequence length
  • More heats per day due to less downtime
  • Increased caster productivity by less slab down-grades
  • Less accumulation of skull
  • Labour and energy saving due to less tundish requirement
  • Reduced overall refractory cost due to longer tundish sequence life
  • Reduced operating cost due to high reliability and very less spares
