To effectively utilize slag remaining in a ladle after completing the casting, without raising a recycle-treatment cost and also, without bringing about bad influence to the other operation.
A method for recycling the slag in the ladle is performed as the followings: the slag 1 remaining in the ladle 3 after completing the casting is exhausted into a molten iron ladle 6 for accomodating the molten iron 8 by tilting the above ladle as the hot-state, and the molten iron 8 is discharged as the main raw material for decarburize-refining in a converter from the molten iron ladle under state of leaving the slag in this molten iron ladle and thereafter, the molten iron 10 tapped off from a blast furnace is received with the above molten iron ladle 6 leaving the slag, and after receiving the molten iron, the received molten iron 10 is desulfurized by using the above slag as a part of the desulfurizing agent 14.
