Experimental investigations on the consumption of graphite electrodes doped with various oxides

Abstract: In order to reduce the burning off of electrodes in electric arc furnaces it is necessary to decrease the specific thermal load at the tip in the arc attachment area. This can be achieved by minimizing the work function of the electrode materials, whereby the peak temperature is reduced. The work function of doped graphite electrodes was investigated under conditions prevailing during standard industrial practice in order to achieve transferable results. The measurement equipment developed to meet this require… Show more

“…Most recent publications are devoted to the arcs as applied to metallurgy and to plasma synthesis of fullerenes (see e.g. [1][2][3][4][5] and [6,7], respectively). Nowadays the arcs with graphite electrodes at atmospheric pressure have also shown their potential as plasma generators in plasma reactor systems for metal recovery from wastes [8].…”
