METHOD FOR CONTROLLING NITROGEN CONTENT IN MOLTEN STEEL

摘要

According to an aspect of the present invention, a method of controlling nitrogen content in molten steel may include: inputting scrap into an electric furnace; Forming molten steel by charging molten iron while dissolving scrap by applying electric power to an electric furnace; And descending the molten steel from the electric furnace to the ladle furnace, and adding a carbonizing agent to the molten steel from the point where the molten steel is 30%.
