Abstract The method for alloying working surface of casting with special performance is characterized by that the molten steel containing alloy element meeting specific performance requirements of casting and molten steel containing no alloy element are respectively injected into mould continuously in turn, and the molten steel containing alloy element is completely centralized in working surface of the casting with specific performance requirements. The advantage of said invented is that adopting special molten steel injection process and centralizing noble alloy element in working surface of casting with specific performance requirement to save lots of alloy elements, obviously reduce production cost and effectively raise service life of casting.
