摘要:
The present invention relates to a method of operating an electric arc furnace containing a furnace shell having a tapping hole, a plurality of electrodes, and a rotating apparatus that rotates the furnace shell around a vertical axis relative to the electrodes, the method contains a charging step of opening an opening-and-closing door of a scrap bucket containing a metal material and falling the metal material into the furnace shell in which the furnace shell is rotated by the rotating apparatus until a direction of a line connecting a center of the furnace shell to a center of the tapping hole intersects an extension direction of a seam at a closing side of the opening-and-closing door, the opening-and-closing door is opened in this positional relationship to charge the metal material.
