sub entry nozzle

Sub Entry Nozzle / Shroud (SEN / SES) is an isostatically pressed refractory tube used for flow of steel from Tundish to Mould. The primary function of SEN / SES is to prevent re-oxidation of steel between the tundish and the mould. The design of the SEN / SES strongly influence the casting process by modulation of steel flow and thermal charasteristics inside the mould. Longer casting duration is achieved with special Zirconia containing mixes for the slag zone. Different glaze compositions are available that cover all range preheating and casting conditions. Latest insulation materials like Bio Soluble Ceramic Fiber and Fibre free Insulating Coating for SEN and SES eliminate the risk of exposing our customers to hazardous traditional ceramic fiber. Different design SEN & SES are available for conventional slab, thin slab, billet, bloom and beam blank casters. Customized SEN designs are offered through flow modelling simulations.

Monoblock Stopper is used mainly for flow control on Molten Steel poured from tundish to mould. Monolithic Stopper is installed in the Tundish above the Sub Entry Nozzle and the gap between stopper head and Nozzle decide the throughput requirement of Molten Steel inside the Mould.
Argon can be blown into the tundish through argon inlet to prevent nozzle from Clogging ( specially designed feature wherever it is required we design and customise accordingly)
