Abstract
An apparatus for automatically charging scrap into an arc furnace wherein an inactive position at which a scrap bucket charged with the scrap is normally placed is provided adjacent to the arc furnace; a transport mechanism is provided so that the scrap bucket is moved between said position and the arc furnace; and the scrap bucket is brought to and stopped at a position right above the arc furnace so as to charge immediately the scrap into the arc furnace within a short time and without overflowing.
