FIELD: metallurgy of cast iron. SUBSTANCE: method includes treatment of melt with silicon dioxide amounting to 1-3% of charge weight that makes it possible to reduce volume fraction of graphite segregations in iron structure and more uniform distribution on cross-section of casting. EFFECT: improved mechanical properties of cast iron and ductility. 1 tbl
