Thin Slab casting of steel require special design of Sub Entry Nozzle (TSS) for optimum flow parameters in a funnel mould at high casting speeds.
Thin Slab SEN design has direct influence on the formation of solidified shells and the quality of final products. Optimum depth of SEN in the mould is also critical to decrease the vortex in the free surface of the caster.
Longer casting duration is achieved with special Zirconia containing mixes for the slag zone.
Thin Slab SEN operates at high casting throughputs in a confined volume with the objectives of controlling turbulence in order to:
- Stable meniscus
- Avoid mould flux entrapment
- Heat flux removal for shell growth formation
- Inclusion removal
Flow Modelling Simulation based design
IFGL has expertise to provide customised solutions for Thin Slab SEN designs for high throughput casting. Every SEN design gets validated through series of mathematical modelling with the state of art software program using Computational Fluid Dynamics (CFD).
