FIELD: metallurgy. ^ SUBSTANCE: invention relates to metallurgy field and can be used for manufacturing of high-duty cast iron with globular graphite. For receiving of magnesium-bearing nano- modifying agent is blended with water solution of polyvinyl alcohol, chloride of magnesium and iron in molar correlation (10-5):1:1, agreeably, it is evaporated specified mixture before gel formation after what it is implemented carbonation at temperature 350-500C in atmosphere of inert gas with formation of carbon nanotube, filled by chloride of magnesium and iron. ^ EFFECT: invention decrease magnesium losses 1,5-2 times with introduction of nano- modifying agents into the cast iron. ^ 6 ex, 1 tbl, 6 dwg |
