FIELD: metallurgy.
SUBSTANCE: invention relates to ferrous metallurgy and foundry, particularly, to improvement of properties of cast iron used for production of parts operated under variable-sign loads. In compliance with this invention, vanadium compound is reduced in cast iron melt under flux ply in the presence of reducer. Vanadium pentoxide (V2O5) is used as said vanadium compound. Ferrosilicon (FS75) is used as said reducer. Note here that vanadium is introduced into cast iron by chemical dispersion at feed to melt surface of the mix containing 30% of V2O5 , 20% of FS75 and 50% of CaO.
EFFECT: production of high-strength cast iron with ferrite metal base obtained by introduction of vanadium in fine disperse form.
