The invention belongs to the technical field of metallurgy, relates to a first furnace smelting method of a new furnace for electric arc furnace steelmaking, and aims to provide a smelting method which can guarantee the sintering quality of a refractory material and the metallurgical quality of first furnace steel. The method comprises the following steps of: A, preparing materials, namely adding pig iron into a waste steel material, wherein the amount of the added pig iron is 25 to 30 percent of the total weight of the furnace charge, and the amount of added carbon is 1.2 to 1.4 percent of the total weight of the furnace charge; B, loading 60 to 70 percent of the total weight of the furnace charge at the first time, supplying 577 to 592V power after the first loading, supplying 637 to 671V power and 671 to 691V power in turn after arcing is stabilized, and starting an oxygen burner to contribute to smelting when the supplied power reaches 2 to 4MW.h; C, powering off for 15 to 25 minutes before second loading, wherein the second charge is the remaining furnace charge, supplying 577 to 592V power, supplying 637 to 671V power and 671 to 691V power in turn after the arcing is stabilized, and starting the oxygen burner to contribute to smelting after charging; D, after the furnace charge is smelted, powering off for 15 to 25 minutes after the temperature of a weld pool reaches 1,540 to 1,560 DEG C; and E, smelting according to the conventional process.
