MIXTURE FOR FILLING DISCHARGING DUCT OF STEEL CASTING LADLE

摘要

FIELD: ferrous metallurgy. ^ SUBSTANCE: mixture contains: flake graphite, 1 - 4 mass %; vein quartz, 11 - 34 mass %; chromite concentrate, 65 - 85 mass %. Fraction size of chromite concentrate is no more than 2 mm. Addition of flake graphite allows eliminate caking of mixture. Adding of chromite concentrate provides increased mobility of mixture grains and mixture may be completely poured out from discharging ducts of metering nozzles. ^ EFFECT: improved efficiency of casting unit. ^ 2 cl, 3 tbl, 2 ex
