FIELD: siderurgy.
SUBSTANCE: invention concerns the siderurgy area and may be used when manufacturing the remelting fabricating parts that are used in the cast iron foundry production. The metal stock is loaded for melting inside an induction furnace until the melted down composition is obtained. In the furnace, upon the mirror of fusion the carbonates of the alkaline-earth metals are introduced in amounts of 10-20%, and the carboniferous material depending upon the required chemical composition of cast iron. The invention permits to intensify impregnation with carbon process, eradicates occurrence of refining foam and facilitates the sulfur removal.
EFFECT: intensification of impregnation with carbon process and eradication of occurrences of refining foam.
