摘要

Fluid flow in the mold has a significant impact on the quality of continuously cast steel products.Since it is strongly influenced by the SEN design,attention has to be paid on its geometry.In this paper the main principles of a novel SEN type will be described.Water modeling and Computational Fluid Dynamics(CFD)are applied to characterize the flow pattern under different conditions.Furthermore,the interaction with electromagnetic stirring(M-EMS)is analyzed by means of a liquid melt model.Finally,actual steel plant performance data and observations are discussed.
