2017-5-16u2002·u2002The direct current arc burns between the graphite electrode seeming as a cathode and the anodic melt. Figure 9: Flows in the DC furnace The voltages in the voltage drop fields of cathode and anode UK =10 and UA = 30 V are oriented so that the losses are minimised at the graphite cathode and with that also the tip consumption of the electrode is ...
