This invention relates to a method for stabilizing FeO in the slag of an electric arc furnace using intermittent pulverized carbon injection. It involves periodically opening injection valves to adjust the injection flow rate and frequency of carbon powder, thus developing an intermittent injection process. By precisely calculating the carbon content and molten pool formation time under different scrap steel ratios, the method designs the timing and initial injection process for carbon powder injection corresponding to different smelting conditions. Utilizing the imbalance between oxygen supply intensity and decarburization rate at different smelting stages, the method develops intermittent injection processes and late-stage injection processes, adjusting injection parameters in real time based on the foam slag index.
