Correlation between the Steel Quality and the Mould Fluid Flow Characteristics Induced by the GYRONOZZLE

This paper summarizes the results describing the mould flow patterns induced by single port nozzles, multiport nozzles and by the GYRONOZZLE, a novel concept for improving the flow conditions in bloom and billet casting.
Based on the correlation of the modeling results with data obtained from industrial field trials regarding the solidification structure of the as-cast products it is concluded, that the Gyronozzle increases the efficiency of the electromagnetic mould stirring. A mould flow influenced by the port geometry of the GYRONOZZLE and optimized parameters for the electromagnetic stirring can improve the solidification structure of as-cast products.
