Steb > Solution & Implementation
BILLET/BLOOM CASTING
  • High-speed casting technology.
  • Modular design for fast dimensional change.
  • Dynamic secondary cooling system.
  • Wear-resistant components with prolonged life.
  • State-of-the-art modular equipment for maintenance optimization.

COOLING BED
Final temperature calculation model
Our experience enables us to calculate the final temperature for the billet at the turn-over cooling bed. The final temperature is calculated by means of functional relations mathematical model, linking:
  • Billet in temperature.
  • Size of the billet.
  • Local temperature.
  • Residence time of the billet on the turn-over cooling bed.

CASTING IMPLEMENTATION
Our technical experience and simulation model enables us to train and verify our casters in the following metallurgical skills:

Temperature profiling

Inner straigh expansion

  • Surface straightening.
  • Calculation of the effective metallurgical length as the function of "K" solidification factor and casting speed.
