ABSTRACT OF THE DISCLOSURE A method of operating a steel making electric furnace which uses arc heat of electrodes to melt metal is taught. In accordance with the method, gas is blown through a plurality of holes in which at least one of the holes is in each of a plurality of plugs, and the molten metal is then blown in an amount of 1 to 40N 1/min per hole, 20 to 800N 1/min per plug and at a pressure of less than 10 kg/cm2.g. The plugs are spaced apart from each other within a furnace bed on the bottom of the furnace. The blowing takes place when a period of refining starts, in which charged scraps are molten thereby constituting the molten metal, to a period in which the molten metal is tapped. The swelling height of the molten metal is controlled to not more than 1000 mm.
