METHOD OF SPHEROIDIZING TREATMENT OF SPHERULITIC IRON Russian patent published in 2000 - IPC

Abstract RU 2146295 C1

FIELD: metallurgy, particularly, production of spherulitic iron used in casting of castings in automotive and agricultural machine building, parts of changeable metallurgical equipment, manufacture of pipes and articles by centrifugal casting. SUBSTANCE: method consists in that prior to pouring of molten metal into ladle, magnesium-containing alloying composition in capsules from copper and/or nickel is placed there. Ratio of capsule metal weight to weight of magnesium-containing alloying composition placed in it is 0.6-2.5. EFFECT: reduced smoke liberation, pyroeffect and decreased consumption of magnesium-containing alloying composition. 1 tbl, 1 ex
