FIELD: metallurgy.
SUBSTANCE: invention can be used in machine building and automotive industry for productions of casts of high-strength cast iron with spherical and vermicular shape of graphite. Spheroidising modifier as ferromagnesium silicon foundry alloy is placed at ladle bottom rear, opposite the tip, so that coverage of ladle bottom does not exceed the radius of bottom circle. Then, ladle is filled with iron melt for 30-60 s. Note here that at teeming, iron melt jet is fed closer to ladle tip.
EFFECT: higher efficiency.
