For high quality production at elevated casting speeds, moldlevel fluctuation is a substantial problem with standard bifurcatedSENs. An innovative whirl SEN has been developed which reducesthe mold fluid velocity, penetration depth and mold level fluctuation.

Numerical modelling and planttests were carried out to optimize the core type and operatingcondition of the EMBR.

The properties of viscosity, melting point andsolidification point were separately correlated with the chemistriesusing MC, a multiple correlation software package, to derive threecorrelation equations.

Two-dimensional slab bulging model could not estimate the criticalconditions of internal crack at the solid/liquid interface.

The macroscopic models involved the governingequations of heat flow and composite solid shell resistance (CSSR).
