Compositions for binderless briquette of in-mold innoculant of cast iron, binderless briquettes manufactured from the same, and manufacturing method of binderless briquettes

摘要

PURPOSE: A composition for the manufacture of binderless briquettes for an in-mold inoculant of cast iron, binderless briquettes manufactured from the same, and a method of manufacturing binderless briquettes are provided to produce cast iron of excellent quality by mainly using the composition without binder. CONSTITUTION: A composition for manufacture of binderless briquettes for an in-mold inoculant of cast iron comprises Mg 10 weight% or less, CaF2 8 weight% or less, BMA of 20-80 weight%, Fe of 5-65 weight%, misch metal of 1.0-2.5 weight%, and Ba of 1.5-3.5 weight%. Binderless briquettes are manufactured by mixing the powder of the composition, putting the mixture in a mold, and applying molding pressure to the mold without binder.
