The effect of electropulsing on the microstructure formation in solidification of mould flux has been investigated.Experimental characterization and image analysis reveals that the electropulsing treatment reduces 46% porosity and increases the interfacial perimeter to area ratio by 100%.The latter provides strong evidence that electric current influences interfacial energy.Dendrite arm spacing is Celebration reduced considerable.Electropulsing promotes the anisotropic crystal growth and retards the formation of interconnected crystal network.

The latter is favourable to the current flow, liquid Toy Storage Bag refilling and lubrication.The work demonstrates that electropulsing can be used to modify the microstructure of slag and hence to control the horizontal heat transfer rate in the mould, which is desirable in continuous casting of advanced high strength steels.
