FIELD: ferrous metallurgy, namely compositions of modifying agents for producing cast pieces of cast iron with vermicular or compact graphite.
SUBSTANCE: complex modifying agent contains next relation of components, mass %: magnesium, 0.5 - 10; calcium, 0.1 - 10; aluminum, 0.1 - 10; silicon, 30 - 80; total content of cerium and yttrium, 0.5 - 15; manganese, 0.1 - 15; lanthanum, 0.001 - 10; magnesia, 0.001 - 5; total content of oxides of rare earth metals, 0.001 - 10; iron, the balance.
EFFECT: stable process of producing cast pieces of cast iron with vermicular or compact graphite, lowered casting stresses, improved heat conductance of cast iron.
