Method for modification of primary structure of cast iron with vermicular graphite intended for thin-walled castings

摘要

modification structure of original iron with graphite in ductile wermikularnym tube containing by mass: 20 - 37% nickel, 1 - 6% silicon, up to 2% chromium, to 1.5% manganese, 2,4 - 35% carbon to 0,02% sulphur, the rest iron is that together in wermikularyzatorem and modyfikatowem grafityzującym is titan of 0.03 - 0.35 mass% relative to the weight of the liquid metal, which is then poured into forms of iron within 2.5 minutes of treatment modification.
