FIELD: metallurgy, namely foundry, particularly processes for obtaining magnesium-containing modifying agents used for producing cast iron with spheroidal graphite.
SUBSTANCE: method comprises steps of preparing, heating, pouring and crystallizing melt under protective flux. Melt is heated till temperature higher than liquidus temperature t1 by 10 - 99°C; pressure value is in range 10-3 - 0.9 x 10-1 MPa. Invention allows prepare modifying master alloy with easy-to-melt magnesium-containing component, with high density and uniform distribution of properties in the whole volume.
EFFECT: improved properties of master alloy at minimum consumption of materials.
