The article investigates the modifying and refining effect intensification using a pulsed effect on the cast iron melt through an additional high-intensity electropulse-based source. The correlation between the impulse action intensity, the macro- and micrometer dimensions of grains, and mechanical properties of a cast billet has been established. It has been found that using a complex method for modifiers introduction under conditions of melt impulse treatment enables to obtain especially fine and special structures with increased mechanical properties.
