Definitions
- FIG. 1 is a section through an electrode according to the invention, while FIG. 2 is a top view of the electrode of FIG. 1.
- the present invention which concerns a giant electrode of graphite for maximum output operation of electric arc furnaces, is characterized in that it comprises an electric arc stabilizing wick.
- Wick electrodes with small diameter are principally known for use in connection with movie projection lamps and for illuminating purposes.
- synthetic carbon products are involved of a diameter of up to 20 mm. and a length of approximately 50 cm.
- the present invention is concerned with the application of this principle of increasing the power of electrodes to giant electrodes for the electric arc furnace.
- the advantage of this new electrode results from a combination of individual effects. In this connection there are to be mentioned:
- a giant electrode of graphite for maximum power operation of electric light arc furnaces which comprises a graphite body having an axial central bore of small diameter therethrough compared to total electrode cross section, and a thin wick arranged centrally in said bore, said thin wick specifically assuring stabilization of electric light are furnace operation and simultaneously reducing graphite consumption.
- An electrodeof electric light are furnaces according to claim 1, in which the mass of the thin wick contains a compound selected from the group consisting of n TiC and TiN in which n is selected from one to four for stabilization at higher current load demand during maximum power operation of electric light are furnaces.
- the wick electrode according to invention gets by with er small bores.
- instancje aj bore of 1fiw -wi.ll suffice for pmdficifig stabilizing efifeiit.
- Tit TiN may be ob -zoxaldes'horethertitanium as well Em" i
