Abstract: A method for producing ductile iron alloys and products thereof, and in particular ductile iron alloys with at least a partial pearlitic structure, is disclosed. The improved ductile iron alloy may be used in vehicle parts, in particular disc brake rotors. The method for producing a ductile iron alloy includes heating an initial composition in a furnace to produce a molten mixture, transferring the molten mixture to an inoculation ladle, inoculating the molten mixture with an inoculant for a predetermined inoculation time to produce an inoculated molten mixture, and pouring the inoculated molten mixture into a mold to produce a ductile iron alloy with at least a partial pearlitic structure.

Abstract: The invention relates to a method for producing ductile iron alloys and products thereof, and in particular ductile iron alloys with at least a partial pearlitic structure. The inventors have sought to develop an improved iron alloy for providing vehicle parts, in particular disc brake rotors. The method for producing a ductile iron alloy comprises the steps of: heating a steel composition in a furnace to produce a molten steel; transferring said molten steel to an inoculation ladle; inoculating said molten steel with an inoculant for a predetermined inoculation time to produce an inoculated molten steel; and pouring said inoculated molten steel into a mould to produce a ductile iron alloy with at least a partial pearlitic structure.
