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 form or continuous casting mould. This paper presents the results describing the influence of selected parameters of rotating electromagnetic field enforcing the movement of liquid metal in the form on the morphology of graphite in grey cast iron. The results were fragmented graphite flakes in conditions of regulating the rate of cooling in the range of temperature [...] and casting with the influence of electromagnetic field.
