Beschreibung
Zusammenfassung:	The invention relates to the technical field of steel casting, and particularly relates to a cored wire for reducing the degree of superheat of molten steel and a use method thereof. A cored wire provided by the invention comprises a core inorganic heat absorbing material and an external metal shell. The cored wire is fed into molten steel in a mold by a wire feeder during a casting process. A metal shell of the cored wire is gradually melted and joint to the molten steel (without affecting composition of molten steel), and meanwhile, the core inorganic material melts by absorbing latent heat and floats up to a surface, so as to reduce the degree of superheat of the molten steel, promote a cooling rate of molten steel, and finally improve the quality of castings.
