One way to improve the unification of the casting structure may be the application of forced convection of liquid metal during the crystallization in the mould or continuous casting mould. This paper presents the results describing the influence of selected parameters of rotate electromagnetic field enforcing the movement of liquid metal in the mould on the morphology of graphite in grey cast iron. Different form of flake graphite was obtained in conditions of changes in the rate of liquid metal solidification in the range of pouring and liquidus temperature T_ZAL - T_L and casting with the influence of electromagnetic field.
