This invention relates to a method for modifying molten steel slag with carbon dioxide throughout the entire process under normal pressure. The method includes: first, adding the first batch of steel slag to a slag pot for melting; then, adding 10%–35% of the mass of the first batch of hot molten steel slag as a steel slag fracturing agent to the slag pot; next, unloading a second batch of hot molten steel slag into the slag pot through a slag discharge device of a converter or continuous casting system; then, adding a second batch of hot molten steel slag as a steel slag fracturing agent to the slag pot, repeating this cycle until the slag pot is full. This method achieves complete dissociation and efficient separation of the molten steel slag by adding modified steel slag tailings and steel slag fracturing agent in layers into the slag pot, utilizing the phased and temperature-segmented release of carbon dioxide by the fracturing agent. This completely solves the problems of iron-rich casting residue, desulfurization slag welding pot, and agglomeration. This method can be combined with the phased supply of solid carbon dioxide to synergistically improve the strength of the steel slag. The residue after supply can be utilized as a resource, making it environmentally friendly and efficient.
