Description
The internal geometric profile nozzle plays an important role in the obtaining proper flow patterns in the thin slab continues casting funnel mould. After some geometry design concepts are derived, numerical and physical modelling like water modelling is applied to elaborate and verify if the design can meet the expected target. For the numerical simulation, some attentions should be taken to avoid some numerical modelling uncertainty caused by the mesh quality, different turbulence models, multi-phase phenomena in the reality, etc. In this paper a so called “S-port” with patent protected thin slab casting nozzle from RHI Magnesita was introduced. The special featured nozzle structure working like traditional concepted flow divider elaboration with the improved numerical method to customize the flow to required casting conditions and throughout was discussed. Finally, the nozzle design and the numerical modelling method was verified and tested in the RHI Magnesita’s water modelling laboratory in Leoben.
