One of the methods, which improved unification of structure may be application of forced movement in time of metal crystallization. In studies to generating of forced movement of liquid metal was applied electromagnetic filed. In aim of determination of electromagnetic field influence on morphology of graphite was made a comparison between microstructure of cast iron ingots, which were poured in conventional conditions and with action of electromagnetic field. The results of studies show improvement in graphite morpholgy on condition that suitably slow process of casting solidification.
