The invention relates to an environment-friendly top slag modification method suitable for IF steel. In the steel tapping process of a converter, steel ladle top slag modification is not carried out;molten steel is subjected to vacuum treatment after reaching RH; and after vacuum decarburization is finished and before aluminum adding complete deoxidation, a top slag modification agent is added into a vacuum tank. According to the environment-friendly top slag modification method, pollution of smoke dust to the surrounding working environment is avoided, and environment protection is facilitated; and after being fast and uniformly molten, the modification agent is combined with steel ladle top slag, the function that the top slag modification agent adsorbs Al2O3 inclusions of the IF steelis achieved better, and the cleanliness of the molten steel can be improved easily.
