Abstract
A current feed for an electrode of an electric smelting furnace. The current feed conductors lead to the electrode above the furnace hearth, and a current feed element surrounds the electrode and is arranged coaxially to the electrode and concentrically to the current feed conductors. Contact jaws are arranged concentrically to the electrode. The current-conducting cross section of the current feed element varies continuously from a maximum on the side away from the furnace axis to a minimum on the side adjacent to the furnace axis.
Claims10
A current feed for an electrode of an electric smelting furnace which comprises a plurality of electrodes disposed around and parallel to the furnace axis, said current feed comprising:
- (a) a current feed element which:
- (i) surrounds the electrode;
- (ii) is coaxial to the electrode;
- and
- (iii) has a larger current-conducting cross-section on the side of said current feed element remote from the furnace axis than on the side of said current feed element adjacent to the furnace axis;
- (b) current feed conductors leading to said current feed element;
- (c) a plurality of contact jaws which, during use of the current feed, are in electrical contact with the electrode;
- and
- (d) a plurality of current conductors providing electrical connection between said plurality of contact jaws and said current feed element.
