Abstract (en)
[origin: WO9600877A1] An electric arc furnace for melting scrap iron is to be of the simplest possible design while preventing thermal loads on the side walls caused by the electrodes and damage to the electrodes during charging. The electric arc furnace is distinguished by the combination of the following elements: a base (2) to take the melt (10); an upper part (13) projecting from the base (2) with a side wall (15); a lid (16) covering the upper part (13); a charging shaft (17) arranged approximately centrally to the upper part (13) with a considerably smaller diameter (21) than that (22) of the upper part (13). The inside (18) of the charging shaft (18) is connected to the inside (20) of the furnace by an aperture (19) in the lid (16) and there are electrodes (31) in approximately symmetrical radial array directed obliquely into the inside of the furnace projecting approximately towards the centre (14) of the electric arc furnace.
