| Abstract Scope |
The current distribution and temperature distribution in the electrode play an important role in the consumption of the electrode. In this paper, the three-dimensional unidirectional coupling model of current and heat transfer carrying alternating current is established, and the effects of magnesia-carbon material embedded in electrode on the current distribution and temperature distribution are studied. It is found that in the three-phase electrodes, the current is mainly distributed in the region near the left electrode. With the increase of the radius of the magnesia-carbon material embedded in the three-phase electrodes carrying alternating current, the region with high current density expands in the opposite direction to the left electrode, the temperature of the upper region and the height of the high-temperature region of the electrode are decreasing. Magnesia-carbon material embedded in the electrode can not only reduce the skin effect and proximity effect, but also reduce the temperature of the electrode. |
