A method is disclosed for smelting low nitrogen steel using a dual-shell electric furnace having two furnace shells and an arc power system for alternatively electrically heating the furnace shells in which one of the two furnace shells is respectively sequentially subjected to electric heating, feeding, sealing of a molten pool and blowing of a combustion medium and oxygen to initiate smelting; when the temperature of molten steel in the furnace shell subjected to electric heating reaches a target temperature, initiating electric heating of the other furnace shell. The method can shorten the smelting period and improve the throughput of a production line of an electric furnace to efficiently meet the market requirements for low nitrogen steel while reducing the emission of environmental pollutants associated with known processes.
